Análisis Factorial Confirmatorio de la Escala de Desempeño Laboral en Profesionistas del Valle de México durante el Confinamiento por COVID 19

A psychometric study is presented using confirmatory procedures of the Work Performance Scale of Koopmans, Bernaards, Hildebrandt, Van Buuren, Van der Beek y De Vet (2013) in its Argentine version carried out by Gabini y Salessi (2016) to obtain construct validity in accordance with the original structure and concurrent criterion validity through correlation with the Work Expectations scale (Villa-George, Moreno-Jiménez, Rodríguez-Muñoz, y Villalpando, 2011). A non-experimental-cross-sectional design was used and snowball sampling was applied. The sample was made up of 404 professionals from the Valley of Mexico who were working remotely. The three-factor structure was analyzed (performance in the task, counterproductive behaviors and performance in the context) and with 12 items, the results indicate good reliability of the instrument, an adequate fit of the model to the data, and relevant convergent construct validity. It is considered that the scale is a recommended instrument for the evaluation of Work Performance in Mexican professionals.

The feeding siblings questionnaire (FSQ): Development of a self-report tool for parents with children aged 2–5 years

Over the last decade, there have been repeated calls to expand the operationalisation of food parenting practices. The conceptualisation and measurement of these practices has been based primarily on research with parent-child dyads. One unexplored dimension of food parenting pertains to the evaluation of practices specific to feeding siblings. This study describes the development and validation of the Feeding Siblings Questionnaire (FSQ) – a tool designed to measure practices in which siblings are positioned as mediators in parents’ attempts to prompt or persuade a child to eat. Item development was guided by a conceptual model derived from mixed-methods research and refined through expert reviews and cognitive interviews. These interviews were conducted in two phases, where parents responded to the questionnaire primarily to test i) the readability and relevance of each item, and ii) its overall feasibility. The instrument was completed by 330 parents (96.1% mothers) in Australia with two children aged 2–5 years, and repeated by 133 parents (40.3%) two weeks later. Exploratory factor analysis was performed on baseline data. Internal consistency and test re-test reliability of the subsequent subscales were examined. Construct validity was assessed through comparisons with existing measures of food parenting practices and child eating behaviours. The final FSQ scale included 22 items, reflecting five food parenting practices: sibling competitiveness, active sibling influence, threatening unequal division of food, sibling role modelling, and vicarious operant conditioning. Internal consistency and test re-test reliability estimates were high, and there was some evidence of convergent construct validity. While its factor structure should be confirmed in a different sample, the FSQ offers a novel tool for assessing, monitoring, and evaluating feeding interactions beyond those confined to the parent-child dyad.

중국 예비유아교사 직업정체성 척도 개발 및 타당화

The purpose of this study is to explore the components of preservice early childhood teachers' professional identity in China and to develop a valid and reliable scale to measure the level of preservice early childhood teachers' professional identity.
 To identify the factors that constitute preservice early childhood teachers' professional identity, 13 subscales and 62 preliminary items were extracted through literature analysis and in-depth interviews. A Delphi survey was conducted to verify the appropriateness of the items by experts, and exploratory factor analysis and reliability analysis were conducted to determine the final five components and 33 items.
 The final item of the preservice early childhood teacher professional identity Scale was used to test the item favorability, validity, and reliability. The results of the item validity analysis showed that all items met the assumption of normality and showed good item discrimination. Confirmatory factor analysis (CFA) was conducted to verify validity, and the model fit of the scale (RMSEA .059) was found to be adequate. In addition, the standardization coefficient (.636 or higher) and average variance extracted (AVE) values of each construct's convergent validity were checked and verified through the covariance correlation between the discriminant validity components. Due to the high correlation of the constructs, multicollinearity among the constructs was tested to confirm their independence. The factor reliability of the scale is more than .867, and the total item reliability is .964, which is very high.
 The preservice early childhood teachers' professional identity scale developed in this study proved to be a valid and reliable scale to measure the level of preservice early childhood teachers' professional identity in various training programs in China.

The Lum emotional availability of parents scale among Portuguese adolescents: a psychometric evaluation

ABSTRACT Emotional availability of parents plays a crucial role in the psychological well-being and development of adolescents. However, previous studies have primarily focused on assessing maternal emotional availability. The Lum Emotional Availability of Parents (LEAP) scale was developed, considering both mothers’ and fathers’ emotional availability. This study aimed to examine the psychometric properties of the LEAP scale among Portuguese adolescents (N = 202). The results confirmed the unifactorial structure of the LEAP scale. Convergent construct validity was supported. Specifically, adolescents’ perceptions of higher emotional availability from parents were related to better health-related quality of life. The LEAP scale also demonstrated small but positive associations with emotion regulation, with higher emotional availability being linked to lower use of expressive suppression and greater use of cognitive reappraisal. In conclusion, the findings suggest that the LEAP scale is a valid instrument for assessing adolescents’ perceptions of both mothers’ and fathers’ emotional availability.

Validation of the Spanish version of the body image acceptance and action questionnaire (BI-AAQ-Spanish): Measurement invariance across cultures

The purpose of this study was to assess the psychometric properties of a Spanish version of the Body Image Acceptance and Action Questionnaire (BI-AAQ) and its recently developed 5-item version, the BI-AAQ-5. The BI-AAQ measures psychological flexibility/inflexibility regarding body image. A sample of Spanish adults (n = 938) completed the BI-AAQ and a battery of measures (including body mass index, psychological flexibility, exposure to and internalization of sociocultural body image expectations, body dissatisfaction, and eating disorder symptoms). Measurement invariance was tested against a U.S. American adult sample (n = 866) that completed the English version of the BI-AAQ. The unidimensional factor structure of the BI-AAQ and BI-AAQ-5 was replicated in both samples using confirmatory factor analysis, with model fit indexes ranging from adequate (e.g., CFI = 0.95) to excellent (e.g., CFI = 0.99). Internal consistency was good for both instruments across samples (α = 0.90 to 0.97). Measurement invariance analyses confirmed full configural and metric invariance and scalar partial invariance. The Spanish BI-AAQ and BI-AAQ-5 showed clear evidence of convergent and incremental construct validity. Both instruments’ scores correlated substantively with theoretically related variables. In addition, the results of a conditional process analysis showed that body-image psychological flexibility measured with either instrument moderated the mediated effect of pressure to conform to cultural ideals of body image on disordered eating through internalization of body image ideals and body dissatisfaction. We concluded both instruments are likely suitable for conducting cross-cultural research with Spanish and English-speaking samples.

Convergent construct validity of the Brazilian version of the Houghton scale.

After lower limb amputations, a decrease in gait capacity, even with prostheses, is common and persistent. Functional ability involves multiple constructs; therefore, several outcome measures, such as performance tests or self-report questionnaires, should be used to evaluate people with amputation who use prostheses. To analyze the convergent construct validity of the Brazilian version of the Houghton scale in a sample of lower limb prosthesis users. Volunteers selected were older than 18 years with any level of lower limb amputation and prosthesis use for at least 6 months. In this study, evidence of construct validity of the Houghton scale was established by the Spearman rho correlation with the Brazilian translation of the Prosthetic Limb Users Survey of Mobility and with the Physical Function (PF) and Emotional Well-being subdomains of the Medical Outcomes Study 36-Short Form Health Survey. Seventy-one volunteers were recruited for the study. The sample consisted mainly of men (70.4%) with a mean age of 50 ± 12 years. The primary cause of amputation was traumatic (53.5%), and most participants (54.9%) had a transtibial amputation. The Houghton questionnaire correlated strongly with the Brazilian translation of the Prosthetic Limb Users Survey of Mobility questionnaire (rho: 0.74, p < 0.01) and weakly with the PF and Emotional Well-being of the 36-Short Form Health Survey (rho: 0.06 and rho: 0.22, respectively, p > 0.05). This study showed evidence of convergent construct validity of the Houghton questionnaire to measure and classify functional use of lower limb prostheses, with great value to clinical practice. Additional work is needed to assess other measurement properties in different samples.

Cross-Cultural Adaptation and Validation of the Arabic Version of the Prolapse Quality of Life Questionnaire in the United Arab Emirates.

Given the extensive translation of the Prolapse Quality of Life Questionnaire (P-QoL) into many languages, it is imperative to develop an Arabic version to facilitate the study of pelvic organ health within the Arabian culture. The aim of this study was to investigate, cross-culturally adapt, and validate the Arabic version of the P-QoL. This study involved cross-cultural adaptation and psychometric testing. A total of 90 participants were included in the study. This cross-sectional study was carried out in two phases; during phase I, the P-QoL was translated and adapted from English into Arabic. The Arabic version was psychometrically validated during phase II using the test-retest reliability and internal consistency with Cronbach's alpha coefficient, convergent construct (CC) validity among the four study tools using Spearman's coefficient (r), and discriminative validity using Mann-Whitney test to find the differences between the means of the two samples. A satisfactory level of semantic, conceptual, idiomatic, and content comparability was reached in the cross-cultural adaptation of the Arabic version of the P-QoL. The internal consistency was high in terms of psychometric validation, with a Cronbach's alpha coefficient of 0.971 for the P-QoL. The test-retest results showed high reliability, with the interclass correlation coefficient (ICC) of the P-QoL determined as 0.987. The convergent construct validity was highly acceptable (moderately strong), reflecting a positive correlation between the Arabic version of the P-QoL and the Australian Pelvic Floor Dysfunction Questionnaire (APFD) (r = 0.68; p < 0.001). Similarly, a significant convergent validity of the Arabic version of the P-QoL and the Visual Analogue Scale (VAS) (r = 0.47; p < 0.001) was observed, as well as a correlation between the APFD and the VAS (r = 0.46; p < 0.001). However, there was no significant correlation between the 12-Item Short-Form Survey (SF-12), the P-QoL, the APFD, and the VAS. Based on the significant correlation found between the Arabic APFD and the VAS, the results reveal good reliability, internal consistency, and construct validity. It is recommended that Arabic-speaking females with pelvic organ prolapse use the Arabic version of the P-QoL. More research is needed to assess the responsiveness of the P-QoL.

Translation, transcultural adaptation, and validation of PedsQL 3.0 Sickle Cell Disease Module into Brazilian Portuguese.

Despite the high prevalence of sickle cell disease (SCD) in Brazil, no studies have described the validation of an SCD-specific health-related quality-of-life (HRQoL) instrument in children. We validated PedsQL 3.0 Sickle Cell Disease Module (PedsQL-SCD) for Brazilian Portuguese, and cross-validated it with PedsQL 4.0 Generic Core Scale (PedsQL-GCS) in children with SCD. PedsQL-SCD was translated and culturally adapted using forward and reverse translations. PedsQL-SCD and PedsQL-GCS were tested in children and adolescents with SCD aged 2-18years and their caregivers. Validity was assessed using the Pearson and intraclass correlation coefficients, and reliability measured with Cronbach's alpha. PedsQL-SCD was validated in 206 children with SCD (median age 14years, range: 8-18) and 201 caregivers. Among patients and caregivers, the mean total score for PedsQL-SCD was 65.7 and 64.1, respectively. The mean total score for PedsQL-GCS was 73.1 and 68.9 among patients and caregivers, respectively. The internal consistency for PedsQL-SCD and PedsQL-GCS was good; Cronbach's alpha coefficients ranged from .59-.93 to .64-.83 among patients and from .60-.95 to .65-.85 among caregivers, respectively. Most intercorrelations between PedsQL-SCD and PedsQL-GCS, for patients and caregivers, had medium to large effect sizes (range: .23-.63 and .27-.64, respectively). Pain and pain impact domains of PedsQL-SCD and physical dimension of PedsQL-GCS had the highest cross-correlation (.63 and .6 for patients; .63 and .64 for caregivers, respectively), confirming convergent construct validity. PedsQL-SCD is a valid, culturally appropriate measure to assess HRQoL in children with SCD in Brazil and is well-correlated PedsQL-GCS.

Validity and Reliability of the Turkish Version of School Function Assessment in Children with Special Needs

ABSTRACT Background To assess the validity and reliability of the Turkish Version of School Function Assessment in children with special needs. Methods School children between 6 and 12 years of age with special needs and their typically developing counterparts participated in the study. The School Function Assessment (SFA) was the main outcome with the Pediatric Evaluation of Disability Inventory providing data for the convergent construct validity analysis. Results The SFA’s convergent construct validity analysis results were satisfactory. There were no differences between genders, and significant differences between children with and without special needs; showing an acceptable discriminative construct validity and known-group validity for the SFA. The Cronbach’s alpha scores were over 0.90 for all domains, showing an excellent internal consistency. Implications for School Health Policy, Practice and Equity Wide usage of the SFA in school settings can enable tailoring specific educational and rehabilitative interventions through making the children’s limitations and strengths within the school context clear. Conclusions The results indicate that the Turkish version of the SFA is a valid and reliable assessment tool for school children with disabilities. This tool can help teachers and therapists to understand children’s school functioning.

Psychometric properties of the Caregiver's inventory neuropsychological diagnosis dementia (CINDD) in mild cognitive impairment and dementia.

The Caregiver's Inventory Neuropsychological Diagnosis Dementia (CINDD) is an easy tool designed to quantify cognitive, behavioural and functional deficits of patients with cognitive impairment. Aim of the present study was to analyse the psychometric properties of the CINDD in Mild Cognitive Impairment (MCI) and Dementia (D). The CINDD, composed by 9 sub-domains, was administered to fifty-six caregivers of patients with different types of dementia (D) and 44 caregivers of patients with MCI. All patients underwent an extensive neuropsychological assessment, the Neuropsychiatric Inventory (NPI) and functional autonomy scales. The reliability, convergent construct validity and possible cut-off of CINND were measured by Cronbach's alpha (α), Pearson's correlation and ROC analysis, respectively. The D and MCI patients differed only for age (p=0.006). The internal consistency of CINDD was high (α= 0.969). The α-value for each CINDD domain was considered acceptable, except the mood domain (α=0.209). The CINDD total score correlated with cognitive screening tests; each domain of the CINDD correlated with the corresponding score from either tests or NPI (p<0.05), except for visuo-spatial perception skills and apathy. A screening cut-off equal to 59, can be used discriminate D from MCI (Sensitivity=0.70, Specificity=0.57). The CINDD is a feasible, accurate and reliable tool for the assessment of cognitive and behavioural difficulties in patients with different degree of cognitive impairment. It may be used to quantify and monitor caregiver-reported ecological data in both clinical and research settings.

Fear of Movement in People with CRPS: A Psychometric Evaluation of the Tampa Scale-11 for Kinesiophobia.

People with complex regional pain syndrome (CRPS) commonly report a fear of movement that can worsen symptoms and increase disability. The Tampa Scale of Kinesiophobia (TSK) is used to evaluate fear of movement and (re)injury, but findings have been inconsistent in different populations. To evaluate the psychometric properties of the Persian version of TSK-11 in individuals with upper limb CRPS. Specifically, to determine if the factor structure aligns with the original two-factor model, consisting of "activity avoidance" and "somatic focus." People with CRPS (n=142, mean age=42, 54% female) completed the TSK. The psychometric testing included internal consistency and test-retest reliability (intra-class correlation coefficient), and convergent construct validity. Confirmatory and Exploratory factor analyses (CFA, EFA) were performed to evaluate the structural validity. The TSK-11 showed acceptable internal consistency (Cronbach alpha 0.93) and excellent test-retest reliability (ICC=0.93, 95% CI: 0.92 to 0.94). The Standard Error of Measurement and Minimal Detectable Change were 4.3 and 11.7, respectively. The results also demonstrated excellent criterion validity (r=0.81). CFA demonstrated that the original two-factor model did not fit. EFA derived a two-factor solution with different items. The factor structure accounted for 64.91% of the variance, and the internal consistency of the factors was acceptable (>0.90). Expert consensus suggested naming these two factors as Fear-avoidance, Magnification & Helplessness. The TSK-11 demonstrates excellent retest reliability in people with CRPS. The original two-factor structure was not confirmed, and a new 2-factor structure of the TSK-11 proposed consisting of subscales for Fear Avoidance beliefs and Magnification/Helplessness. Given the overlap between these constructs and the construct of pain catastrophizing, further study is needed to clarify both measures' content validity and relative uniqueness.

Validating a fear-of-falling-related activity avoidance scale in lower limb prosthesis users.

Limited available data suggest that fear of falling (FoF) may be common among lower limb prosthesis users (LLPUs) and associated with negative rehabilitation outcomes. The impact of FoF on outcomes may be exacerbated when fear leads to self-imposed declines in activity. There is a need to identify the validity of fear-of-falling-related activity avoidance scales in LLPUs. To evaluate the convergent, discriminant, and known-group construct validity of the modified Survey of Activities and FoF in the Elderly (mSAFE) for LLPUs. Secondarily, we sought to determine if the mSAFE scale could be reduced without losing information regarding construct validity. Online survey. Not applicable. Fifty-nine persons with unilateral or bilateral amputation at the transtibial or transfemoral level, with ≥6 months experience using a definitive prosthesis for activities other than transfers. Participants completed an online survey that consisted of the mSAFE and questions to assess FoF (yes/no), fear-of-falling-related activity avoidance (yes/no), as well as previously validated scales capturing related and unrelated constructs. T-tests were used to compare mSAFE score between yes/no respondents for known-group construct validity. Correlations between mSAFE and previously validated surveys assessed convergent and discriminant validity. Analyses were repeated on a reduced number of mSAFE items following a redundancy analysis. Not applicable. Significant correlation coefficients of |0.440-0.825| were found for convergent validity with evidence of known-group construct validity (p < .021 for all comparisons). There was evidence for discriminant validity, with non-significant associations for two-of-three correlations. Results from validity analyses for a shortened 6-item mSAFE were similar to that for the full scale. This study provided initial evidence regarding validity of the mSAFE as a measure to assess fear-of-falling-related activity avoidance in LLPUs. A 6-item scale may be appropriate if the full scale would be taxing or time-consuming.

Validity and Reliability of the Persian Version of Barriers to Physical Activity Questionnaire for People With Mobility Impairments.

Although physical activity (PA) is an important determinant of health, physically disabled individuals tend to have a sedentary lifestyle. The Barriers to Physical Activity Questionnaire for People with Mobility Impairments (BPAQ-MI) is a self-report instrument evaluating PA barriers. This study was intended to evaluate the validity and reliability of the Persian version of BPAQ-MI (P-BPAQ-MI) and to report the prevalence and severity of PA barriers among Persian-speaking individuals. The translation and back translation of the BPAQ-MI was conducted according to an internationally accepted guideline and tested on 163 participants to assess its reliability and validity. Internal consistency and test-retest reliability were analyzed using Cronbach alpha and Spearman correlation coefficient. Convergent construct validity was established by comparing the scores of P-BPAQ-MI and The Baecke Habitual Physical Activity Questionnaire. Known-groups construct validity was assessed with regard to type of assistive device and sex of the individual. Prevalence and severity of the barriers were reported by computing the percentage and means of "yes" answers. The P-BPAQ-MI domains demonstrated very good internal consistency (Cronbach alpha of .77-.95) and excellent test-retest reliability (Spearman rho of .73-.96) with a significant inverse small correlation with Baecke Habitual Physical Activity Questionnaire indexes. The P-BPAQ-MI successfully discriminated between individuals with different assistive devices and sex. Community Built Environment barriers were the most prevalent and severe. The P-BPAQ-MI is a valid and reliable instrument to assess the PA barriers of people with physical disability. The community barriers were the most frequently reported obstacles to PA.

Health-Related Quality of Life in Patients With Ventricular Assist Device: Psychometric Evaluation of the German Version of the Quality of Life With a Ventricular Assist Device Questionnaire.

Ventricular assist device (VAD) implantation has become an alternative treatment for patients with end-stage heart failure. In Germany, valid and reliable instruments to assess health-related quality of life in patients with VAD are lacking. The aim of this study was to present the psychometric validation of the German version of the Quality of Life with a Ventricular Assist Device questionnaire. In a multicenter, cross-sectional study, 393 participants (mean age, 58.3 years; 85.8% male, 60.3% bridge to transplant, and 72.8% living with VAD for ≤2 years) completed the German Quality of Life with a Ventricular Assist Device questionnaire of physical, emotional, social, cognitive, and meaning/spiritual domains. Item and confirmatory factor analyses were conducted to test item difficulty and discrimination and the underlying structure, respectively. To examine internal consistency, Cronbach α was assessed. Convergent construct validity was tested using the Kansas City Cardiomyopathy Questionnaire and the Patient Health Questionnaire-9. Readability was examined using Flesch Reading Ease index and Vienna Factual Text Formula. The Quality of Life with a Ventricular Assist Device showed reasonable item difficulty (Ptotal = .67) and mostly moderate to high discriminatory power (rit > 0.30). In confirmatory factor analysis, root-mean-square error of approximation (0.07) was acceptable for model fit, but no other indices. Acceptable internal consistency was found (α ≥ 0.79), with the exception of the cognitive domain (α = 0.58). The overall questionnaire and single domains demonstrated convergent validity (r ≥ 0.45, P < .001). The questionnaire showed adequate readability (Flesch Reading Ease, 64.11; Vienna Factual Text Formula, 6.91). Findings indicate a promising standardized clinical instrument to assess health-related quality of life in patients with VAD.

Validation of a measure to assess decision-making autonomy in family planning services in three low- and middle-income countries: The Family Planning Autonomous Decision-Making scale (FP-ADM).

Integrating measures of respectful care is an important priority in family planning programs, aligned with maternal health efforts. Ensuring women can make autonomous reproductive health decisions is an important indicator of respectful care. While scales have been developed and validated in family planning for dimensions of person-centered care, none focus specifically on decision-making autonomy. The Mothers Autonomy in Decision-Making (MADM) scale measures autonomy in decision-making during maternity care. We adapted the MADM scale to measure autonomy surrounding a woman's decision to use a contraceptive method within the context of contraceptive counselling. This study presents a psychometric validation of the Family Planning Autonomous Decision-Making (FP-ADM) scale using data from Argentina, Ghana, and India. We used cross-sectional data from women in four subnational areas in Argentina (n = 890), Ghana (n = 1,114), and India (n = 1,130). In each area, 20 primary sampling units (PSUs) were randomly selected based on probability proportional to size. Households were randomly selected in Ghana and India. In Argentina, all facilities providing reproductive and maternal health services within selected PSUs were included and women were randomly selected upon exiting the facility. Interviews were conducted with a sample of 360 women per district. In total, 890 women completed the FP-ADM in Argentina, 1,114 in Ghana and 1,130 in India. To measure autonomous decision-making within FP service delivery, we adapted the items of the MADM scale to focus on family planning. To assess the scale's psychometric properties, we first examined the eigenvalues and conducted a parallel analysis to determine the number of factors. We then conducted exploratory factor analysis to determine which items to retain. The resulting factors were then identified based on the corresponding items. Internal consistency reliability was assessed with Cronbach's alpha. We assessed both convergent and divergent construct validity by examining associations with expected outcomes related to the underlying construct. The Eigenvalues and parallel analysis suggested a two-factor solution. The two underlying dimensions of the construct were identified as "Bidirectional Exchange of Information" (Factor 1) and "Empowered Choice" (Factor 2). Cronbach's alpha was calculated for the full scale and each subscale. Results suggested good internal consistency of the scale. There was a strong, significant positive association between whether a woman expressed satisfaction with quality of care received from the healthcare provider and her FP-ADM score in all three countries and a significant negative association between a woman's FP-ADM score and her stated desire to switch contraceptive methods in the future. Our results suggest the FP-ADM is a valid instrument to assess decision-making autonomy in contraceptive counseling and service delivery in diverse low- and middle-income countries. The scale evidenced strong construct, convergent, and divergent validity and high internal consistency reliability. Use of the FP-ADM scale could contribute to improved measurement of person-centered family planning services.

Feasibility, criterion and construct convergent validity of the 2-minute walk test and the 10-meter walk test in an oncological context

ObjectiveTo examine the feasibility, the criterion, and the construct convergent validity of the 2-Minute Walk Test (2MWT) and the 10-Meter Walk Test (10MeWT) against the 6-Minute Walk Test (6MWT) to assess walking capacity in people with cancer. The criterion concurrent validity of a self-test version of the 10MeWT (10MeWTself-test) was also evaluated against the 10MeWT. MethodsFifty-six people with cancer performed the 2MWT, the 10MeWT at comfortable and fast speeds, the 6MWT, and the 10MeWTself-test. The feasibility of the tests was assessed using safety, adverse events, space requirements, time taken to administer and interpret the tool, equipment or training required, cost, and portability as criteria. Validity was assessed using Pearson correlation coefficients and Bland Altman plots. ResultsThe 2MWT, 6MWT, 10MeWT, and 10MeWTself-test were feasible for people with cancer. The 2MWT and the 10MeWT results were moderately to strongly correlated with the 6MWT results (0.61 < r < 0.84, p < 0.001). The 10MeWTself-test results were strongly correlated with the 10MeWT results at comfortable and fast speeds (r = 0.99, p < 0.001). ConclusionsThe 2MWT, 10MeWT, and 10MeWTself-test are simple, rapid, and feasible tests for use in people with cancer. The strong correlation between the 2MWT and 6MWT results indicates that the 2MWT can be used as an alternative walking capacity assessment tool. The 10MeWT results moderately correlated with those of the other two tests, suggesting that it partially measures the same construct of walking capacity in walking-independent outpatients with cancer. The 10MeWTself-test showed promising results but needs further investigations in ecological settings.

Construct and criterion validity of the HEXACO Medium School Inventory Extended (MSI-E).

In this cross-sectional study we aimed at: 1) validating the observer (Obs) version of HEXACO Medium School Inventory Extended (MSI-E); 2) establishing convergent and divergent construct validity of the HEXACO-MSI-E; 3) establishing criterion validity of HEXACO-MSI-E. We administered the HEXACO-MSI-E, the Big Five Questionnaire-Children (BFQ-C), the Internalizing and Externalizing scales of Youth Self Report (YSR), some items of the 2019 Middle School Youth Risk Behavior Survey (YRB) and some items about adolescents' values, beliefs, behaviors, and desired features of a possible future job to 1175 adolescents (Mage = 12.03, SD = 0.89) and the observer version of these measures (except for BFQ-C) to 854 parents or legal guardians. The factorial structure and the reliability of the Observer Report of HEXACO-MSI-E were confirmed. Convergent and divergent validity were successfully established with a version of the inventory filled out by parents. Convergent and divergent validity were also established with BFQ-C notwithstanding some only apparent anomalies. Criterion validity was established with respect to four specific groups of criteria collected in both self-report and observer form. HEXACO-MSI-E traits were more predictive with respect to self-report than to observer criteria and the majority were common. Together with the positive results of this study, implications and issues for future studies are discussed.

Development and psychometric properties of a questionnaire about knowledge of lay people about traumatic dental injury.

The level of knowledge about traumatic dental injuries (TDI) of lay people from a national point of view has never been studied and there is currently a lack of validated research instruments on this issue. The present study aims to develop and validate a questionnaire (TDI-Q) to assess the knowledge of lay people about TDI, including participants from the five regions of Brazil. TDI-Q was drafted, in Brazilian Portuguese, based on the recommendations of the International Association of Dental Traumatology (IADT). Before its application, TDI-Q was evaluated by dentists, lay people, linguists, and psychometrists. The questionnaire was applied to measure temporal stability at two distinct times, with an interval of 15-20 days between the two applications: test (n = 110) and retest (n = 50). The presence of floor and ceiling effects were investigated by analyzing the frequency of responses of the questionnaire; convergent construct validity was tested through Spearman's correlation; the Mann-Whitney test was applied to discriminant construct validity. Temporal stability and internal consistency were evaluated through intraclass correlation coefficient and Cronbach's alpha, respectively. The floor and ceiling effects were not observed (0.9% and 2.7%, respectively); convergent validity analysis indicated a positive and strong correlation (r = 0.50; p < .001). Significant discriminant construct validity (p < .05) was observed. Satisfactory internal consistency (α = 0.7) and temporal stability (ICC = 0.82, p < .001) were also achieved. TDI-Q proved to have good psychometric properties and to be a reliable tool for evaluating the knowledge of lay people regarding TDI in the Brazilian population.

Psychometric properties of the Romanian version of the female sexual function index (FSFI-RO)

BackgroundFemale sexual dysfunction (FSD) is a highly prevalent health disorder and no self-report questionnaire on female sexual function is available in Romanian. Therefore we considered the Female Sexual Function Index (FSFI) to be the most appropriate due to its excellent psychometric properties. The FSFI is a measuring scale with 19 items that assess the six domains of female sexual function: desire, arousal, lubrication, orgasm, satisfaction and pain. The paper aims to analyze the psychometric reliability and validity of the FSFI-RO (Romanian Version of the Female Sexual Function Index).Methods385 women (aged 18 to 51) enrolled in the present study. To assess the presence of FSD we used the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria for sexual dysfunction. Then we categorized the participants into two groups: the FSD group (41%) and the healthy control group (59%). Women were then asked to fill out a form that included sociodemographic information and the FSFI-RO questionnaire. A sample of 50 women agreed to re-answer FSFI-RO in a 4-week interval in order to evaluate the test-retest validity of the questionnaire. The data were summarized using descriptive statistics: the test-retest reliability was measured by the intraclass correlation coefficient (ICC); Cronbach’s alpha was employed to evaluate the internal consistency of the Romanian version of the FSFI, and validity was assessed by the content and construct validity.ResultsThe results showed high test-retest reliability, with ICC from 0.942 to 0.991 in the domains and 0.987 in the total score. Regarding the internal consistency of the FSFI-RO, Cronbach’s α coefficients were found to be high (α = 0.944). Convergent construct validity proved to be moderate to high in desire, arousal, lubrication, orgasm and, satisfaction domains, and weak correlation in the pain domain. Regarding the discriminant construct validity, the scores for each domain and the total score showed statistically significant differences between the FSD group and the control group.ConclusionsThe FSFI-RO showed similar psychometric properties to those of the original version, therefore being a reliable and valid instrument that can be used in Romanian-speaking women.

Validation of the Simplified Chinese Palliative Care Nursing Self-Competence Scale: Two Cross-sectional Studies.

Due to the increasing burden of life-limiting illnesses, the need for palliative care has increased. Nurses' palliative care competence is a vital factor in improving its accessibility. A reliable instrument is needed to measure nurses' competence in providing palliative care. Our aim was to translate and culturally adapt the Palliative Care Nursing Self-Competence Scale (PCNSC) into the Palliative Care Nursing Self-Competence Scale-Simplified Chinese (PCNSC-SC). Two cross-sectional studies were conducted after content validity had been confirmed during the instrument's translation and adaption. The convergent validity, construct validity, internal consistency, and homogeneity were evaluated in both the first and second studies. Test-retest reliability was assessed only in the first study. Clinical nurses who had a registered nurse qualification certificate and at least 12 months of work experience from a tertiary hospital in Hubei, China participated in the 2 studies. The PCNSC-SC contains 8 dimensions and 34 items, based on goodness-of-fit indices and confirmatory factor analysis. The Cronbach's alpha of the PCNSC-SC was .984 and .990 in the 2 studies, respectively. The test-retest reliability of the PCNSC-SC after 2 weeks was .717. The PCNSC-SC can be used to evaluate perceived self-competence in palliative care of Chinese nurses with good reliability and validity.
