Validation of a scale to assess adherence to oral chemotherapy based on the experiences of patients and healthcare professionals (EXPAD-ANEO).

Background: Lack of adherence to Oral antineoplastic agents (OAAs) treatment has important clinical, social and economic consequences. Objective: To develop and validate a novel instrument for assessing adherence to OAAs, based on the reported experiences of people with cancer in relation to their treatment and the opinions of the healthcare professionals who care for them. Methods: We performed a multicenter validation study of a scale designed to assess adherence to OAAs. First, a steering committee developed the items for an initial scale, based on the results of a qualitative study that evaluated patients' and professionals' experiences with this treatment. We then assessed the validity and reliability of the initial scale in a sample of 268 outpatients with cancer who received their OAAs from four Spanish hospitals. Results: The mean age of the sample of 268 outpatients was 64.1 (standard deviation [SD] 12.4) years, and 47% of participants were women. With the results of this analysis, we developed the EXPAD-ANEO scale, which has 2 factors, one for beliefs and expectations and another for behavior. Both factors explain 52% of the explained common variance. Good reliability was obtained, with a McDonald's omega of 0.7 for the first factor and 0.6 for the second factor. The fit indices were optimal (Root Mean Square Error of Approximation = 0.02, Comparative Fit Index = 0.99, Tucker Lexis Index = 0.99 and Standardized Root Mean Squared Residual = 0.03), which verifies the appropriateness of the items to the model. We measured EXPAD-ANEO criterion validity against pill count, obtaining a specificity of 80%. We measured convergent validity with the Morisky-Green test and found a significant association (p < 0.001). We measured divergent validity with questions on health literacy from the 16-item European Health Literacy Survey and found no correlation (p = 0.153). Conclusion: EXPAD-ANEO is the first validated instrument for evaluating patients' experiences with and adherence to OAAs, providing valuable information that can help health professionals to establish individual strategies or collective programs for improving therapeutic results and reducing healthcare costs.

Pediatric Nurse Practitioner Knowledge of and Attitudes Toward Human Trafficking: A Psychometric Evaluation

Human trafficking is an urgent health threat. This study sought to psychometrically validate the novel Pediatric Nurse Practitioner Knowledge and Attitudes Toward Human Trafficking scale. Using data from a 2018 study of pediatric-focused advanced practice registered nurses (n=777), this secondary analysis examined dimensionality and reliability of the survey. The Cronbach α for scale constructs was < 0.7 for knowledge and 0.78 for attitudes. Exploratory and confirmatory analyses identified a bifactor model for knowledge with relative fit indexes within standard cutoffs, root mean square error of approximation=0.03, comparative fit index=0.95, Tucker-Lewis index=0.94, and standardized root mean square residual=0.06. The attitudes construct indicated a 2-factor model with root mean square error of approximation=0.04, comparative fit index=0.99, Tucker-Lewis index=0.98, and standardized root mean square residual=0.06, within standard cutoffs. The scale is a promising tool in advancing nursing response to trafficking but needs further refinement to increase utility and uptake.

Fast prediction of the performance of the centrifugal pump based on reduced-order model

In the present paper, the prediction of the performance of a centrifugal pump is investigated based on proper orthogonal decomposition (POD) reduced-order model (ROM). Firstly, the POD method is used to analyze the characteristics of the complex flow field inside the centrifugal pump, especially the eigenvalues of the velocity field and pressure field, and then the ROM of the flow field in the centrifugal pump is established then. After that, the established reduced-order model is used to predict the internal flow field. The results show that the POD mode field can reflect the spatial scale distribution of the flow field. The low-order flow field reflects the large-scale flow field structure, while the high-order flow field reflects the small-scale flow field structure. With the established ROM, the overall pump head (0D, 0-dimensional parameter) can be predicted with the relative error of less than 5%, and the standard root mean square error (normalized root mean square error, NRMSE) of pressure field and velocity field (3D, 3-dimensional parameter) is less than 4% and 8%, respectively. The efficiency and accuracy of both 0D and 3D parameters’ prediction motivate the fast prediction of multi-scale simulation of the large-scale industrial system in the future.

Validation of Turkish Parental Perception on Antibiotics Scale

Objective: Antibiotic misuse is a significant public health problem worldwide. Parents’ perceptions of antibiotics are critical for the antibiotic intake of children. The study’s aim was to validate the Turkish Parental Perception on Antibiotics Scale. Methods: This is a scale validation study. The data were collected through a questionnaire that consisted of 15 questions about the demographic and socioeconomic characteristics of the family and the Turkish Parental Perception on Antibiotics Scale. The scale, developed by Alumran et al., is a 5-point Likert type and consists of 31 items. The high scores obtained from the non-cut-off scale indicate better antibiotics perception. Experts completed the language adaption and content validity of the scale. Confirmatory factor analysis was used for construct validity. Reliability was tested by internal consistency coefficients. Results: One thousand eight people participated in the study. 68.8% of the participants were mothers. The mean age of the mothers was 35.7±5.0, and the mean age of the fathers was 39.4±5.2 years. The percent of high school and above graduates was 51.2% among mothers and 56.0% among fathers. According to the confirmatory factor analysis, the fit index values were standardized root mean square residual (SRMR)=0.06, goodness-of-fit index (GFI)=0.90, root mean square error of approximation (RMSEA)=0.06, comparative fit index (CFI)=0.95, non-normed fit index (NNFI)=0.93. The fit index values were good or excellent and confirmed the 5-factor structure. It was found that the internal consistency coefficients calculated for reliability were 0.79 for the whole scale and ranged between 0.63 and 0.86 for the subscales. Conclusion: The Turkish Parental Perception on Antibiotics Scale is a valid and reliable measurement tool. Further research is needed to determine the current situation regarding antibiotic perception.

Multifractal descriptors ergodically characterize non-ergodic multiplicative cascade processes

Biological and psychological processes routinely break ergodicity, meaning they fail to have stable means (Mean) and independent variation over time that we might find in additive white Gaussian noise (awGn). One possible reason for this failure of ergodicity is the failure of biological and psychological processes to exhibit independence across time. Multifractal evidence has long suggested that biological and psychological processes show strong signatures of nonlinear interactions across scales. These cross-scale interactions sooner befit a cascade-dynamical process than awGn. The present work thus compares awGn to simulations of multiplicative binomial cascades, submitting both types of series and shuffled versions of each to the Thirumalai-Mountain method for estimating ergodicity breaking. Estimating ergodicity breaking for original awGn and cascade series allows us to examine the sources of ergodicity breaking across the sequence, e.g., in temporal correlations specifying nonlinear interactions across scales, and examining ergodicity breaking of the shuffled series allows us to assess the raw, sequence-independent contribution of distributional properties (e.g., the heavy tails of a cascade) without the original temporal sequence. Raw cascade fluctuations and the standard deviation (SD) and root mean square (RMS) series describing those raw fluctuations break ergodicity, but nonlinear, cascade-dynamical descriptors: multifractal spectrum width (Δα) and multifractal nonlinearity (tMF), maintain ergodicity. Interestingly, the fundamentally linear descriptor, fractal Hurst exponent (HfGn) shows moderate ergodicity breaking when describing the fundamentally nonlinear cascade processes, but the linear descriptor coefficient of variation (CV) controls for multiplicative relationships between SD and Mean and maintains ergodicity. We conclude that the ergodicity of statistical descriptors depends on how well they can portray nonlinearity (Δα and tMF) or at least multiplicativity (CV) of the underlying cascade processes.

Psychometric properties of the Fletcher Recovery Housing Alliance Measure (FRHAM-12)

ABSTRACT Background: Recovery Housing (RH), an important resource for substance use disorder (SUD) recovery, centers on shared lived experience. Program evaluation considers the contribution of environmental factors to outcomes, yet most research on outcomes has focused on patient factors and fidelity to protocols. Investigations of process measures reflecting the dynamic interplay between patient factors and the treatment program are limited. Alliance, one’s perceived connection with others, is a process measure associated with mental health outcomes and includes domains “tasks,” “goals,” and “bonds.” We posit that alliance serves as a proxy construct to measure the impact of shared experience in RH. Objectives: Develop and assess the psychometric properties of the Fletcher Recovery Housing Alliance Measure (FRHAM-12) for RH. Methods: A cross-sectional survey with the 12-item FRHAM-12 was administered to 271 individuals (60% men, 39% women, 1% other) within six RH centers in Kentucky. Item-total correlations, internal consistency reliability, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted. Results: The FRHAM-12 was found to have a strong internal consistency (0.924 alpha coefficient) and the EFA yielded a single component (56.38% of cumulative scale variance). CFA indicated acceptable levels of absolute and relative fit of a unidimensional scale with values of 0.67 and 0.976 for the standardized root mean square residual and relative fit index. Conclusion: This study aimed to construct and validate an initial measure for RH alliance resulted in the brief, FRHAM-12; a tool with strong internal and factor validity. Future research should examine the measure’s predictive and concurrent validity.

Transcultural validation of the “Body Esteem Scale for Adolescents and Adults” among Tunisian adolescents

IntroductionAdolescence is considered as a particularly vulnerable period for body image disturbance. Body esteem is defined as the self-evaluation of one’s own body or appearance.ObjectivesValidate the Body Esteem Scale for Adolescents and Adults (BESAA) in Tunisian adolescents.MethodsWe conducted a cross-sectional study among adolescents who attend Tunisian high school from 11 October 2021 to 11 November 2021.We translated the BESAA into dialectal Tunisian Arabic based on the translation back-translation method. The validity of the scale was evaluated through content validity, reliability and construct validity. We used the Arabic version of Rosenberg Self Esteem Scale as an external validator.ResultsWe recruited 340 adolescents aged between 12 and 19 years’ old. The translated version was considered satisfactory. The internal consistency showed a good result with a Cronbach Alpha of 0,830. The correlation between items and subscales demonstrated statistically significant and logical results. Statistically significant correlations were found between the BESAA and its external validator the Rosenberg Self Esteem Scale (r= 0,422; p&lt; 0,01). The exploratory analysis related three factors similarly to the original version of the questionnaire and in confirmatory analysis. The scale demonstrated good model fit statistics as follow: Comparative fit index= 0,87; goodness of fit index=0,81; adjusted goodness of fit index=0,77; Root Mean Square Error of Approximation=0,1 and Standardized Root Mean Square Residual=0,09.ConclusionsOur BESAA version can be reliably used to conduct further studies and researches on body esteem in the Tunisian population.Disclosure of InterestNone Declared

Validation of Depression, Anxiety and Stress Scale (DASS-21) among healthcare workers during the outbreak of delta variant of SARS-CoV-2 in Ghana

Background: Today COVID-19 is having a dire effect on the mental and physical health of the general population. Although the long-term psychological effects of COVID-19 remain unknown, studies have shown increasing depression, anxiety and stress among healthcare workers. The aim of the study was to examine the psychometric properties and validation of the Depression, Anxiety, and Stress Scale (DASS-21) and evaluate the level of depression, anxiety, and stress among healthcare workers in a tertiary hospital during the SARS-CoV-2 delta variant outbreak. Methods: Using an online questionnaire, we conducted a cross-sectional study on 1201 healthcare workers in a tertiary hospital. The validation of DASS-21 was performed by examining the factorial structure (construct validity) using confirmatory factor analysis (CFA), internal consistency (reliability), convergent validity, discriminate validity and measurement invariance. Results: Cronbach's Alpha was acceptable for depression (0.88), anxiety (0.81), and stress (0.86). CFA provides support for the three-factor oblique model with the following fit indexes: (Chi-Square χ2/ (degrees of freedom) = 1628.5/(186), p &lt; 0.001), comparative fit index (CFI = 0.923), Tucker-Lewis index (TLI = 0.901), standardized root mean square residual (SRMR = 0.0452) and root mean square error of approximation (RMSEA = 0.07). DASS-21 achieved both configural and metric invariance. Conclusions: Our results indicate that DASS-21 is a reliable and valid self-reporting screening tool for depression, anxiety and stress among healthcare workers. This tool is also invariant across sex, doctors, nurses, and non-clinical healthcare workers. Thus DASS-21 is an essential screening tool to identify healthcare workers at a higher risk of developing work-related mental health disorders.

Translation and validation of Greek version of the Pandemic Grief Scale

IntroductionThose who have lost loved ones to COVID-19 may be considered at risk of complicated grief. A 5-item mental health screening tool called the Pandemic Grief Scale (PGS) was developed to find likely instances of dysfunctional grief during the pandemic.ObjectivesTo develop a Greek version of PGS and to explore the validity and reliability among the general population in Greece in order to further use it as clinical mental health screener.MethodsWe conducted a cross-sectional study between January and April 2022, and 342 persons were recruited. The questionnaire included socio-demographic parameters, the PGS, the Brief Resilience Coping Scale to capture tendencies to cope with stress and the Athens Insomnia Scale to assess the insomnia symptoms. Based on experiences over the previous two weeks, each PGS item is scored on a 4-point scale, from 0 (not at all) to 3 (almost every day), with higher rating and a cut-off of 7 indicating dysfunctional grief. Prior to the psychometric validation a linguistic validation and adaptation in Greek was performed.ResultsA total of 342 patients participated in the study, 67.8 % were females and 27.8% were 18-30 years old. Coefficient Validity Ratio (CVR) results showed that 100% (n = 5) of items were acceptable. Value of Cronbach’s alpha was found 0.848. A one-factor model was conducted by Confirmatory Factor Analysis (CFA), giving acceptable global fit indices. The resulting global fit indices [Standardized Root Mean Square Residual (SRMR) = 0.037, Comparative Fit Index (CFI) = 0.952, Tucker–Lewis Index (TLI)= 0.903] showed that the 5 items in one-factor solution proposed by the primary researchers shouldn’t be rejected for the Greek version. The Bartlett Test of Sphericity was 758.08 (p &lt;0.001). The Kaiser-Meyer-Olkin Measure of Sampling Adequacy was 0.826, showing that the data is suitable for factor analysis. The one-factor solution derived in our study consisted of 5 items. The total explained variance was 64.3 %.ConclusionsThe findings of this research support the PGS psychometric validity and reliability. PGS is suitable to be used in healthcare to identify and assist individuals, who are experiencing this type of pandemic-related dysfunctional grief as it is a screening tool that it’s simple to use, access, and understand.Disclosure of InterestNone Declared

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Positive Body Image among Adolescents Scale (PBIAS) into Spanish and Catalan

The Positive Body Image among Adolescents Scale (PBIAS) explores the factors that bolster and interfere with developing and maintaining a positive body image during adolescence. The aim of this study was to translate, adapt, and validate the PBIAS into Spanish and Catalan. A cross-sectional study was conducted for the instrument's translation, cross-cultural adaptation, and psychometric validation. A process of translation, back-translation, expert consultation, and piloting was followed. The reliability and statistical validity were evaluated. The Cronbach's alpha was 0.95 in both the Spanish and Catalan versions. Pearson's correlation coefficients were statistically significant (r > 0.087) for all items analyzed. The resulting values of the Spanish and Catalan versions indicate a good level of concordance (p < 0.001) with the original questionnaire, the comparative fit index being 0.914 and 0.913, the Tucker-Lewis index being 0.893 and 0.892, the root mean square error of approximation being 1.31 and 1.28, and the standardized root mean square residual being 0.051 and 0.060, respectively. The instrument presents a good level of internal consistency, a high level of reliability, and statistical validity compared to the original instrument. The PBIAS in Spanish and Catalan can be a useful assessment instrument for educators and health professionals in the context of adolescent mental health literacy. This work contributes to the Sustainable Development Goals (Goal 3) of the United Nations 2030 Agenda.

Using Structural Equation Modelling to Predict Safety and Health Status among Stone Industries.

The creation of a working organization with a high safety level ensures employees' health in their workplaces, therefore current study evaluated effect the organizational structure on the safety and health in the stone industry. The study was done among the 100 stone industries in Isfahan, Iran. We asked selected participants to complete the organizational structure questionnaire and ELMERI checklists. tested the hypothesis with Smart PLS 3.0. The model fit index showedthe standardized root mean square (SRMR=0.08), the normalized fit index (NFI=0.9), The coefficient of determination (R2 = 0.362), Effect size (ƒ2 was less than 0.2), and the Predictive relevance of the model (Q2=0.216) which is considered a good fit for mode. Also, the relation between formalization and health and safety was significant (β = -0.47). findings suggest that Organization factors are the basic reasons associated with occupational accidents and the main indicator of safety and health performance.

Validation of the Scale Knowledge and Perceptions about Edible Insects through Structural Equation Modelling

Edible insects have been suggested as a more sustainable source of protein, but their consumption varies according to geographical and sociocultural influences. Focusing on the different aspects that can influence people’s attitudes towards edible insects (EI), this work aimed to carry out the statistical validation of an instrument aimed at assessing different dimensions of this field: the KPEI (knowledge and perceptions about EI) scale. The instrument consists of 64 questions distributed by the following dimensions: Culture and Tradition, Gastronomic Innovation and Gourmet Kitchen, Environment and Sustainability, Economic and Social Aspects, Commercialization and Marketing, Nutritional Characteristics, and Health Effects. The data were collected in 13 countries (Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey). The validation of the KPEI scale was made through Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM). The results revealed two acceptable models, both retaining 37 of the 64 initial items, distrusted by the seven dimensions as: Culture and Tradition (5 items), Gastronomic Innovation and Gourmet Kitchen (5 items), Environment and Sustainability (8 items), Economic and Social Aspects (5 items), Commercialisation and Marketing (4 items), Nutritional Aspects (6 items), Health Effects (4 items). Both multifactorial models resulting from the CFA/SEM analyses showed approximately equal goodness of statistical fit indices with values of Root Mean Square Error of Approximation (RMSEA), Root Mean Square Residual (RMR), and Standardized Root Mean Square Residual (SRMR) partially zero and values of Goodness of Fit Index (GFI) and Comparative Fit Index (CFI) approximately one, i.e., very close to a perfect fit. For the first-order model, the ratio between chi-square and degrees of freedom is χ2/df = 13.734, GFI = 0.932, CFI = 0.930, RMSEA = 0.043, RMR = 0.042, SRMR = 0.042; and for the second-order model χ2/df = 14.697, GFI = 0.926, CFI = 0.923, RMSEA = 0.045, RMR = 0.047, SRMR = 0.046). The values of composite reliability (CR = 0.967) and mean extracted variance (MEV = 0.448) are indicative of a good fit. Finally, the reliability analysis indicated a very good internal consistency (Cronbach’s α = 0.941). These results confirm the successful validation of the KPEI scale, making it a valuable instrument for future application at the international level.

Developing and Evaluating a Measure of the Willingness to Use Pandemic-Related mHealth Tools Using National Probability Samples in the United States: Quantitative Psychometric Analyses and Tests of Sociodemographic Group Differences.

There are no psychometrically validated measures of the willingness to engage in public health screening and prevention efforts, particularly mobile health (mHealth)-based tracking, that can be adapted to future crises post-COVID-19. The psychometric properties of a novel measure of the willingness to participate in pandemic-related screening and tracking, including the willingness to use pandemic-related mHealth tools, were tested. Data were from a cross-sectional, national probability survey deployed in 3 cross-sectional stages several weeks apart to adult residents of the United States (N=6475; stage 1 n=2190, 33.82%; stage 2 n=2238, 34.56%; and stage 3 n=2047, 31.62%) from the AmeriSpeak probability-based research panel covering approximately 97% of the US household population. Five items asked about the willingness to use mHealth tools for COVID-19-related screening and tracking and provide biological specimens for COVID-19 testing. In the first, exploratory sample, 3 of 5 items loaded onto 1 underlying factor, the willingness to use pandemic-related mHealth tools, based on exploratory factor analysis (EFA). A 2-factor solution, including the 3-item factor, fit the data (root mean square error of approximation [RMSEA]=0.038, comparative fit index [CFI]=1.000, standardized root mean square residual [SRMR]=0.005), and the factor loadings for the 3 items ranged from 0.849 to 0.893. In the second, validation sample, the reliability of the 3-item measure was high (Cronbach α=.90), and 1 underlying factor for the 3 items was confirmed using confirmatory factor analysis (CFA): RMSEA=0, CFI=1.000, SRMR=0 (a saturated model); factor loadings ranged from 1.000 to 0.962. The factor was independently associated with COVID-19-preventive behaviors (eg, "worn a face mask": r=0.313, SE=0.041, P<.001; "kept a 6-foot distance from those outside my household": r=0.282, SE=0.050, P<.001) and the willingness to provide biological specimens for COVID-19 testing (ie, swab to cheek or nose: r=0.709, SE=0.017, P<.001; small blood draw: r=0.684, SE=0.019, P<.001). In the third, multiple-group sample, the measure was invariant, or measured the same thing in the same way (ie, difference in CFI [ΔCFI]<0.010 across all grouping categories), across age groups, gender, racial/ethnic groups, education levels, US geographic region, and population density (ie, rural, suburban, urban). When repeated across different samples, factor-analytic findings were essentially the same. Additionally, there were mean differences (ΔM) in the willingness to use mHealth tools across samples, mainly based on race or ethnicity and population density. For example, in SD units, suburban (ΔM=-0.30, SE=0.13, P=.001) and urban (ΔM=-0.42, SE=0.12, P<.001) adults showed less willingness to use mHealth tools than rural adults in the third sample collected on May 30-June 8, 2020, but no differences were detected in the first sample collected on April 20-26, 2020. Findings showed that the screener is psychometrically valid. It can also be adapted to future public health crises. Racial and ethnic minority adults showed a greater willingness to use mHealth tools than White adults. Rural adults showed more mHealth willingness than suburban and urban adults. Findings have implications for public health screening and tracking and understanding digital health inequities, including lack of uptake.

Trauma exposure and psychometric properties of the life events checklist among adults in South Africa

ABSTRACT Background: Trauma exposure is widespread and linked to chronic physical and mental health conditions including posttraumatic stress disorder. However, there are major gaps in our knowledge of trauma exposure in Africa and on the validity of instruments to assess potentially life-threatening trauma exposure. Objective: The Life Events Checklist for the DSM-5 (LEC-5) is a free, widely used questionnaire to assess traumatic events that can be associated with psychopathology. As part of a case–control study on risk factors for psychosis spectrum disorders, we used the LEC-5 to examine the frequency of traumatic events and to assess the questionnaire’s factor structure in South Africa (N = 6,765). Method: The prevalence of traumatic events was measured by individual items on the LEC-5 across the study sample, by case–control status, and by sex. Cumulative trauma burden was calculated by grouping items into 0, 1, 2, 3, and ≥4 traumatic event types. Psychometric properties of the LEC-5 were assessed through exploratory and confirmatory factor analyses. Results: More than 92% of the study sample reported experiencing ≥1 traumatic event; 38.7% reported experiencing ≥4 traumatic event types. The most endorsed item was physical assault (65.0%), followed by assault with a weapon (50.2%). Almost 94% of cases reported ≥1 traumatic event compared to 90.5% of controls (p < .001) and 94% of male participants reported ≥1 traumatic event compared to 89.5% of female participants (p < .001). Exploratory factor analysis revealed a 6-factor model. Confirmatory factor analyses of three models found that a 7-factor model based on the South African Stress and Health survey was the best fit (standardized root mean square residual of 0.024, root mean square error of approximation of 0.029, comparative fit index of 0.910). Conclusion: Participants reported very high exposure to traumatic events. The LEC-5 has good psychometric priorities and is adequate for capturing trauma exposure in South Africa.

A psychometric evaluation of Chinese chronic hepatitis B virus infection-related stigma scale using classical test theory and item response theory.

To validate the hepatitis B virus infection-related stigma scale (HBVISS) using Classical Test Theory and Item Response Theory in a sample of Chinese chronic HBV carriers. Feasibility, internal consistency reliability, split-half reliability and construct validity were evaluated using a cross-sectional validation study (n = 1,058) in Classical Test Theory. Content validity was assessed by COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. The Item Response Theory (IRT) model parameters were estimated using Samejima's graded response model, after which item response category characteristic curves were drawn. Item information, test information, and IRT-based marginal reliability were calculated. Measurement invariance was assessed using differential item functioning (DIF). SPSS and R software were used for the analysis. The response rate reached 96.4% and the scale was completed in an average time of 5 min. Content validity of HBVISS was sufficient (+) and the quality of the evidence was high according to COSMIN criteria. Confirmatory factor analysis showed acceptable goodness-of-fit (χ 2/df = 5.40, standardized root mean square residual = 0.057, root mean square error of approximation = 0.064, goodness-of-fit index = 0.902, comparative fit index = 0.925, incremental fit index = 0.926, and Tucker-Lewis index = 0.912). Cronbach's α fell in the range of 0.79-0.89 for each dimension and 0.93 for the total scale. Split-half reliability was 0.96. IRT discrimination parameters were estimated to range between 0.959 and 2.333, and the threshold parameters were in the range-3.767 to 3.894. The average score for test information was 12.75 (information >10) when the theta level reached between-4 and + 4. The IRT-based marginal reliability was 0.95 for the total scale and fell in the range of 0.83-0.91 for each dimension. No measurement invariance was detected (d-R 2 < 0.02). HBVISS exhibited good feasibility, reliability, validity, and item quality, making it suitable for assessing chronic Hepatitis B virus infection-related stigma.

Factor structure of post-operative quality of recovery questionnaire (QoR-15): An Italian adaptation and validation.

The Quality of Recovery questionnaire (QoR-15) is an English instrument for measuring quality of recovery in surgical patients, not yet translated and validated in Italian when the Enhanced Recovery After Surgery (ERAS) Piemonte studies were planned. To produce the Italian version of the QoR-15 questionnaire, to evaluate its factorial structure and to assess the invariance between two types of surgery. The Italian version (QoR-15I) was obtained translating and adapting the original version to the Italian context. The validation was performed suppling the QoR-15I to 3,784 patients enrolled in two parallel stepped wedge cluster randomised trials (ERAS Colon-rectum Piemonte; ERAS Gyneco Piemonte). The factor structure and its invariance between types of surgery was tested using confirmatory bifactor model and multi-group analysis. Comparative fit index (CFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR) fit indices and their changes between nested models were used to assess the factor structure and the invariance. The bifactor model showed good fit (RMSEA = 0.049, CFI =0.957, SRMR = 0.036) and provided a general recovery factor and two specific factors for physical and mental recovery. Eighty-four percent of the common variance is attributable to the general factor, and thus the QoR-15I is sufficiently 'one-dimensional' with an adequate reliability (ωh = 0.70). The ωs values for the physical and mental recovery factors were 0.01 and 0.13, respectively. Multigroup analysis supported configural (RMSEA = 0.053, CFI = 0.950, SRMR = 0.035) and metric invariance (ΔRMSEA = -0.004; ΔCFI = -0.002; ΔSRMR = 0.014), whereas the intercept constraint was removed from item 15 to obtain partial scalar invariance (ΔRMSEA = 0.002; ΔCFI = 0.007; ΔSRMR = 0.004). Construct validity was supported by a negative association of QoR-15I scores with all variables related to worse patient condition and more complex surgery. Our results support the use of the QoR-15I as a valid, reliable, and clinically feasible tool for measuring the quality of recovery after surgery. The results of the confirmatory factor analyses suggest that a unique recovery score can be calculated and support measurement invariance of the QOR-15I across the two type of surgery, suggesting that the questionnaire has the same meaning and the same measurement parameters in colorectal and gynaecologic patients.

The impact of posttraumatic stress disorder on the psychological distress, positivity, and well-being of Australian police officers.

Police officers experience many traumatic events over the course of their career, often resulting in posttraumatic stress disorder (PTSD) and associated psychological distress. Studies have investigated the efficacy of interventions aimed at reducing symptoms of PTSD experienced by police officers, but lacking are studies investigating the impact of PTSD on positivity, a construct we define as a latent variable estimated using self-report measures of optimism, gratitude, self-compassion, and mindfulness. The present study carried out a path analysis of a model testing the hypothesis that PTSD would be associated with increased psychological distress and decreased positivity, both of which influence well-being. The model also evaluated associations between constructs that could be modified through interventions to increase well-being-associations between posttraumatic growth, social support, physical activity and psychological distress, positivity, and well-being. Police officers (n = 506) completed an online survey that included self-report measures of the constructs included in the model being tested. The model tested produced fit indices of root mean square error of approximation (RMSEA) = .089; comparative fit index (CFI) = .960; Tucker-Lewis index (TLI) = .93; standardized root mean square residual (SRMR) = .041 and R² = .79. Results found that neither PTSD or psychological distress had a direct effect on well-being. Psychological distress indirectly influenced well-being by lowering levels of positivity, while positivity was associated with higher scores on the measure of well-being. The implication of the results is that interventions aimed at enhancing positivity could be expected to improve well-being in police officers and offering traditional therapies together with positivity enhancing therapies may have additional benefits over either alone.

Translations and psychometric validation of the Korean version of the Nursing Teamwork Survey.

Enhancing nursing teamwork benefits both patients and nurses. The Nursing Teamwork Survey is a reliable, valid tool to evaluate nursing teamwork. This study was conducted to translate and psychometrically validate the Nursing Teamwork Survey for nurses in Korea. In Phase 1, the Nursing Teamwork Survey was translated into Korean using forward and backward translations. Content and face validity were determined using expert review and pilot testing, respectively. In Phase 2, we evaluated construct and convergent validity and internal consistency, and test-retest reliability. We used survey data from 1119 hospital nursing staff; 98 of whom completed the Korean version of the Nursing Teamwork Survey after 2 weeks. Confirmatory factor analysis showed an acceptable fit (χ2 /df ratio = 3.96, root mean square error of approximation = 0.05, standardized root mean square residual = 0.05, comparative fit index = 0.91, and Tucker-Lewis index = 0.90) with good internal consistency (Cronbach's α = 0.76-93) and test-retest reliability (rs = 0.63-0.83). Convergent validity was supported by the correlation between the subscales of the Korean version of the Nursing Teamwork Survey and the Teamwork Within Units subscale of the Hospital Survey on Patient Safety Culture (rs = 0.45-0.69, ps < 0.01). These findings indicate that the Korean version of the Nursing Teamwork Survey is a reliable and valid measurement for assessing nursing teamwork. The Korean version of the Nursing Teamwork Survey can inform management strategies to promote nursing teamwork and improve patient safety and nurses' well-being.

Structural and cross-cultural validity of the Afrikaans for the Western Cape Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire

BackgroundThe Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire has been translated and cross-culturally adapted to Afrikaans for the Western Cape, within the public health service context of South Africa. The aim of this study was to evaluate structural validity, internal consistency, and cross-cultural validity/measurement invariance of this new translation to increase applicability and clinical utility in a public health service context.MethodsDuring this cross-sectional study, exploratory factor analysis (EFA) was conducted with parallel analysis and oblimin rotation. Confirmatory factor analysis (CFA) and multiple group confirmatory factor analysis (MGCFA) to assess cross-cultural validity/measurement invariance, was employed to test model fit with X2 goodness-of-fit statistic, root mean square error of approximation (RMSEA), standardized root mean square residual (SRMR) and comparative fit index (CFI). Internal consistency was calculated using Cronbach’s alpha.Results109 women and 110 men (n = 219) completed the Afrikaans for the Western Cape and the South African English DASH questionnaire, used during the analysis. Unidimensionality of the Afrikaans for the Western Cape DASH questionnaire was not supported in the 218 questionnaires eligible for inclusion in the analysis [X2 (df) = 1799.10 (405); p value = < 0.01; RMSEA (90% CI) = 0.126 (0.120–0.132); SRMR = 0.09 and CFI = 0.984]. EFA revealed a two-factor structure with Eigenvalues exceeding one explaining 55% and 7% of the variance. The two-factor structure of the Afrikaans for the Western Cape DASH questionnaire was supported during CFA. Cronbach’s alpha revealed good internal consistency of both factors [factor 1 = 0.97 (0.96, 0.97) and factor 2 = 0.92 (0.90, 0.94)]. MGCFA conducted between 218 Afrikaans for the Western Cape DASH and 219 South African English DASH questionnaires (N = 437) revealed that the data supports configural, metric and scalar invariance models during initial model fit assessment. Subsequent hypotheses testing comparing the nested models revealed that scalar invariance holds.ConclusionThe Afrikaans for the Western Cape DASH questionnaire revealed a two-factor structure with good internal consistency across the two factors and demonstrated measurement invariance with the South African English DASH questionnaire.

Lack of voluntary interest and difficulty making eye contact are the most discriminative behaviors of the ASQ:SE and might suggest delays: Results from a large-scale assessment

Background Every child is unique, but development tends to occur in predictable steps and stages. The early identification of infants who face developmental delays is critical, boosting the use of screening tools to determine risks for delays. The city of Rio de Janeiro conducted a large-scale assessment of children who were enrolled in educational facilities using the Ages & Stages Questionnaires: Social-Emotional (ASQ:SE). Objectives We examined the internal structure of the ASQ:SE and its most discriminative items of risks of delays in development among 12- to 60-month-old children. The trajectory of the discrimination parameter of eight anchor items was used to check how well they inform the risk of social-emotional competence delays throughout development. Methods Data from 79,332 children (1–5 years) were analyzed via Samejima Graded Response model of Item Response Theory (IRT). The discrimination (a) and threshold (b) parameters were computed, and errors were achieved via maximum likelihood. Data/codes are available at https://osf.io/by6sf/. Results (a) Item Response Theory analyses supported the unidimensionality of data via the root mean square error of approximation and standardized root mean square residual results (RMSEA). (b) The lack of voluntary interest was the most discriminative risk behavior in the first 5 years. (c) Lack of interest was the most persistent risk behavior. (d) Difficulty making eye contact was nearly as informative as lack of interest. Conclusion Lack of voluntary interest in things should be considered a critical risk-related behavior, and making eye contact is a vital aspect of typical development. Both behaviors may be predictors of children’s delays. MAIN OUTCOMES The ASQ:SE is a valid and reliable tool to measure child development. The internal structure of the ASQ:SE is well-fitted with a unidimensional solution. A child’s age is a vital aspect of the discrimination parameter of the IRT model. Lack of interest in things and difficulty making eye contact are critical risk-related behaviors.
