A psychometric evaluation of the PTSD Checklist for DSM-5 among women experiencing intimate partner violence.

Recent national estimates suggest that 1 in 2 women will experience intimate partner violence (IPV) in their lifetime. Given the high prevalence of posttraumatic stress disorder (PTSD) among women experiencing IPV, it is necessary to consider whether PTSD assessments function adequately for this population. Thus, the present study aimed to evaluate the psychometric properties of the past-month version of the PTSD Checklist for DSM-5 (PCL-5), one of the most widely used self-report measures of PTSD symptoms, in a sample of community women experiencing IPV. Participants were 158 women who had experienced IPV in the past 6 months (Mage = 40.14 years, 39.9% White). The PCL-5 demonstrated good internal consistency, Cronbach's α =.97, and scores were significantly positively correlated with theoretically related constructs (i.e., PTSD symptom count on the SCID-5, IPV severity, substance use, depression, anxiety, and emotion dysregulation); however, it demonstrated poor 30-day stability, r =.38, ICC =.55. The ability of the PCL-5 to discriminate with respect to a PTSD diagnosis was acceptable, AUC =.74. A cutoff score of 21 maximized sensitivity (82.5%) and specificity (55.4%); this is lower than typical cutoffs (i.e., 31-33). Although the PCL-5 has generally demonstrated adequate psychometric properties, findings suggest that it does not function optimally for women experiencing IPV relative to its functioning for other trauma-exposed populations. The lower-than-typical cutoff suggests that the PCL-5 may underestimate PTSD prevalence among women experiencing IPV.

Illegitimate work tasks: an investigation of psychometric properties of the Swedish version of the BITS instrument and its suitability in human versus ‘non-human’ service occupations

BackgroundIllegitimate tasks, i.e. working tasks that are perceived as unnecessary or unreasonable, are commonly measured by the Bern Illegitimate Tasks Scale (BITS). Despite a growing research attention paid to illegitimate tasks, the Swedish version of BITS needs yet to be properly evaluated. Moreover, previous multiorganizational studies in this field have taken for granted, without really testing it, that the instrument functions invariantly in different contexts; a prerequisite for meaningful comparisons.MethodsTwo occupational groups that differs hugely—966 human services workers (teachers and registered nurses) and 750 non-’human service’ workers (construction and IT-workers) were targeted utilizing questionnaires data collected 2018 within the Swedish Longitudinal Occupational Survey of Health (SLOSH) study. Psychometric properties, i.e., reliability, dimensionality, and measurement invariance between the occupations were examined using confirmatory factor analyses and structural equation models. Also, the associations between the two dimensions of illegitimate tasks and job satisfaction and emotional exhaustion, respectively, were tested.ResultsGood reliability was supported and two- versus one-dimensionality showed better psychometric properties. Partial scalar measurement invariance was satisfactory supported with only 25% relaxed constraints of equal intercepts between groups. Examining the two subdimensions revealed different associations with emotional exhaustion, where the associations was more substantial for unreasonable tasks. Nevertheless, the findings point to potential improvements for future investigation.ConclusionsThis study shows that the Swedish version of BITS is working satisfactory and allows for meaningful comparisons of occupational groups. Furthermore, construct validity of the two dimensions was corroborated.

Parent version of the Eating Disorder Examination: Reliability and validity in a treatment-seeking sample

BackgroundAssessment of eating disorders (ED) in youth relies heavily on self-report, yet persistent lack of recognition of the presence and/or seriousness of symptoms can be intrinsic to ED. This study examines the psychometric properties of a semi-structured interview, the parent version of the Eating Disorder Examination (PEDE), developed to systematically assess caregiver report of symptoms.MethodsA multi-site, clinical sample of youth (N = 522; age range: 12 to 18 years) seeking treatment for anorexia nervosa (AN) and subsyndromal AN were assessed using the Eating Disorder Examination (EDE) for youth and the PEDE for collateral caregiver report.ResultsInternal consistencies of the four PEDE subscales were on par with established ranges for the EDE. Significant medium-sized correlations and poor to moderate levels of agreement were found between the corresponding subscales on each measure. For the PEDE, confirmatory factor analysis of the EDE four-factor model provided a poor fit; an exploratory factor analysis indicated that a 3-factor model better fits the PEDE.ConclusionsFindings suggest that the PEDE has psychometric properties on par with the original EDE. The addition of the caregiver perspective may provide incremental information that can aid in the assessment of AN in youth. Future research is warranted to establish psychometric properties of the PEDE in broader transdiagnostic ED samples.

Measuring childbirth-related posttraumatic stress disorder: Psychometric properties of the Italian version of the City Birth Trauma Scale (City BiTS).

The City Birth Trauma Scale (City BiTS) assesses postpartum posttraumatic stress disorder (PTSD) based on the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria. Although it has been validated worldwide, predictive validity has not been previously examined. Moreover, no Italian version of the scale exists. This study aimed to test the bifactor latent structure and alternative models, internal consistency, test-retest reliability, convergent validity, divergent validity, and predictive validity of the City BiTS. Women (N = 629) who had given birth within the past 3 months completed an online survey including sociodemographic and obstetric characteristics, the City BiTS, the Impact of Event Scale-Revised, and the Edinburgh Postnatal Depression Scale. After 3 months, women completed the City BiTS again and reported their intention to breastfeed during the 1-year postpartum. Exploratory factor analysis confirmed the two-factorial structure. In confirmatory factor analysis, the two-factorial solution showed the best model fit. Internal consistency was good to excellent for the subscales and the total scale. Correlation analyses showed strong convergent validity with the Impact of Event Scale-Revised, high divergent validity with the Edinburgh Postnatal Depression Scale, high test-retest reliability, and good predictive validity with the intention to exclusively breastfeed. Moreover, the Birth-Related Symptoms subscale distinguished between different types of delivery. The City BiTS-Italian is the first measure evaluating and diagnosing childbirth-related PTSD symptoms based on Diagnostic and Statistical Manual of Mental Disorders (5th ed.) in Italy. The factorial structure and validity reported in other cultural contexts were confirmed; moreover, findings add evidence to the scale's temporal stability and predictive validity. Besides contributing to clinical purposes, the City BiTS-Italian will facilitate international comparability regarding the prevalence of PTSD following childbirth.

Dysfunctional beliefs associated with hair pulling disorder: an examination in clinical versus non-clinical groups

ABSTRACT Objective Until recently, empirical studies had been limited with respect to investigating factors that influence the onset and maintenance of hair pulling disorder (HPD), particularly regarding the role of dysfunctional cognitions and beliefs. The primary aim of this study was to examine the relationships between symptom severity and belief domains in a sample with hair pulling disorder compared with non-clinical participants, using the Beliefs in Trichotillomania Scale (BiTS); a recently developed measure of relevant negative self-beliefs, coping efficacy beliefs, and perfectionist cognitions. Method Twenty adults with HPD and 43 age- and gender-matched control participants completed the BiTS and several measures of related constructs. Results HPD severity was significantly and positively correlated with negative self-beliefs and low coping efficacy, but not perfectionism, even after controlling for anxiety and depressive symptoms. Focussed hair pulling, but not automatic hair pulling, was correlated with each BiTS domain; however, once anxiety and depressive symptoms were controlled for, the significant relationship between focussed hair pulling and perfectionism was no longer apparent. The BiTS psychometric properties demonstrated good internal consistency and differentiated clinical from non-clinical participants, with clinical participants endorsing greater negative self-beliefs, lower coping efficacy, and greater perfectionism compared with control participants. Conclusions Negative self beliefs, low coping efficacy, and perfectionism have differential relationships with HPD severity and hair pulling styles, variable on the presence of co-occurring anxiety and depressive symptoms. While further support for the BiTS internal consistency was obtained, future examination of divergent validity with a more diverse range of constructs is required.

My precious: development and validation of the conservation of human energy resources index (CHERI)

ABSTRACT Conserving energy resources is crucial for sustaining effort and preventing exhaustion, especially in demanding work environments. Yet, a reliable and valid measure for assessing individuals’ motivation to conserve energy is currently lacking. To fill this gap, we introduce a concise five-item scale, the Conservation of Human Energy Resources Index (CHERI), available in both German (CHERI-G) and English (CHERI-E) versions. In four comprehensive studies (N = 1,814), we evaluated the structure and psychometric properties of both language versions. Our results reveal that the CHERI measures a one-dimensional, homogeneous construct characterized by a high internal consistency (Studies 1, 2, and 4). Our findings also emphasize the CHERI’s sensitivity to change (Study 3) and its meaningful associations with measures from the nomological network of motivation, energy, and effort (Studies 2 and 4). Additionally, we demonstrate the cross-cultural equivalence of the CHERI-G and CHERI-E as well as their equivalence across situational contexts, encompassing both workplace and academic settings (Study 4). Taken together, the present research provides preliminary evidence for the psychometric properties of the CHERI – a measure that can be used to enhance our understanding of energy conservation behaviours and to open new perspectives for advancing research on energy management and recovery.

Introduction and validation of the open symptom framework: a public domain modular framework for patient-reported measurement of symptoms related to cancer and its treatment.

We provide an initial description and validation of some public domain patient-reported outcome (PRO) items to assess cancer symptom burden to address immediate barriers to symptom assessment use in clinical practice and facilitate future research. We created the Open Symptom Framework (OSF), a flexible tool for clinicalcancer-related symptom assessment. The items comprise six components: recall period, concept, symptom, qualifier(s), a definition, and a 5-point Likert-type response. We recruited patients receiving cancer therapy in the United States and United Kingdom. We assessed external construct validity by comparing OSF scores to the PRO-CTCAE measure and assessed reliability, scalability, dimensionality, and item ordering within a non-parametric item response theory framework. We tested differential item functioning for country, age, gender, and level of education. We developed a framework alongside clinical and psychometric experts and debrieifed with 10 patients. For validation, we recruited 331patients. All items correlated with the PRO-CTCAE equivalents (r = 0.55-0.96, all p < 0.01). Mokken analysis confirmed the scalability and unidimensionality of all symptom scales with multiple items at the scale(Ho = 0.61-0.75) and item level (Hi = 0.60-0.76). Items are interpreted consistently between demographic groups (Crit = 0 for all groups). The public domain OSF has excellent psychometric properties including face, content, and criterion validity and can facilitate the development of flexible, robust measurements to fulfil stakeholder need.The OSF was designed specifically to support clinical assessmentbut will function well for research. Further work is planned to increase the number of symptoms and number of questions per symptom within the framework.

Psychometric properties of the maternal breastfeeding evaluation scale: a confirmatory factor analysis

BackgroundIt has been suggested that maternal satisfaction should be included as an additional and appropriate outcome indicator in relation to the breastfeeding process. The aim of this study was to analyze the psychometric properties of various existing versions of the Maternal Breastfeeding Evaluation Scale in a Spanish sample.MethodsThis was a longitudinal observational study, evaluated at three different time points: in the hospital after delivery, and then at five and 12 months after delivery in a Spanish sample. A total of 690 mother participated in this study.ResultsConfirmatory factor analysis results indicated an improved fit of the data to the original model (CFI = 0.984; TLI = 0.982; RMSEA = 0.079). All dimensions of the Maternal Breastfeeding Evaluation Scale are positively associated with breastfeeding rates and negatively associated with perceived difficulty in continuing to breastfeed after returning to work at five months postpartum. Moreover, the scale can predict breastfeeding behavior at 12 months postpartum.ConclusionsThe results of this study indicate that the structure of the original version of the Maternal Breastfeeding Evaluation Scale mean it is a is valid and reliable tool for assessing maternal perceptions of the breastfeeding experience in Spain. This research enhances our understanding of maternal satisfaction with the breastfeeding experience and its potential implications for supporting breastfeeding practices. It is an opportunity for the academic, healthcare, and policy sectors to develop more effective interventions to improve breastfeeding rates and ensure a positive experience for mothers.

Proposing a more conservative Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Effort Index cutoff score for forensic inpatient populations.

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Effort Index (EI) may be unreliable at its standard recommended cutoff score when used with forensic psychiatric inpatient populations given high rates of genuine cognitive impairment. The present study sought to (a) examine the rate of invalid performance on the RBANS EI using the standard cutoff among incompetent to stand trial (IST) inpatients and (b) investigate the psychometric properties of the RBANS EI at various cutoff scores. This study was conducted using archival assessment data collected at a large forensic psychiatric hospital. Across the entire sample (N = 238, 79% male, Mage = 45 years, 24% primary Spanish-speaking), 79% were diagnosed with a schizophrenia spectrum disorder. Experiment 1 of the study (n = 165) contained IST patients who were classified as having a valid presentation. Experiment 2 contained a valid (n = 46) and invalid (n = 27) presentation group comprised of postadjudication and IST inpatients, respectively. In Experiment 1, over one third (36.4%) of the valid presentation sample scored above the standard recommended EI cutoff. In Experiment 2, applying the standard recommended cutoff score of > 3 was associated with a false positive rate of over 20%. Obtaining < 10% false positive errors was achieved at a cutoff score of > 5. At this cutoff score, the estimated local base rate of invalid responding among IST patients was 28%. Clinical and forensic implications and recommendations for adopting this more conservative RBANS EI cutoff score are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

A systematic review of the psychometric properties of the Leicester Cough Questionnaires based on the COSMIN guidelines

BackgroundChronic cough affects around 10 % of the general adult population, impairing all aspects of quality of life. Research questionWhat are the Leicester Cough Questionnaire's psychometric properties? Study design and methodsElectronic searches of PubMed, CINAHL, and ScienceDirect databases were conducted from inception until October 1rst 2022. All full-text articles, published in French or English, aimed at evaluating the LCQ's content validity or psychometric properties were included. The COSMIN Risk of Bias checklist was applied to assess their methodological quality and results. Results were qualitatively summarised and rated by a modified GRADE approach. Results40 studies were included accounting for 8731 adults, subject to cough or a respiratory condition. Chronic cough (>8 weeks) was the most represented. The LCQ's total score is relevant and comprehensible for the assessment of the impact of cough on QoL. The original 3-factor model showed a satisfactory model fit. Good convergent validity was found for the total and physical domain scores. These scores demonstrate good internal consistency and test retest reliability, with some variability noted and they are responsive to change. Recent estimates of MID thresholds were 1.7 and 0.4 for total and domain scores respectively. The quality of the studies is globally poor. InterpretationThe LCQ is a valid outcome to assess the intra-individual impact of cough on QoL and to detect large changes in quality of life mainly in a short-term clinical trial setting. Clinical trial registrationThe protocol was registered with PROSPERO (CRD42022355191).

Psychometric analysis of the kansas city cardiomiopathy questionnaire-23 in a european population

Abstract Background People affected by heart failure (HF) often exhibit poor quality of life, which places a great deal of burden on the healthcare systems. The Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 is one of the most widespread instruments to measure quality of life in this population. So far, its psychometric properties have been investigated by a broad array of research, but the overall findings reveal inconsistency of the factorial structure and lack of rigorous psychometric testing. Objective The aim of this study was to evaluate the psychometric properties of the KCCQ-23 in a European cohort of HF patients. Methods The data used for this study were collected for the MOTIVATE-HF study, which was a three-arm, multicenter, randomized controlled trial to evaluate the effect of motivational interviewing for improving self-care in HF. A group of 510 patients (median age 74 years, IQR=18, 58% males) completed the KCCQ-23 along with clinical and psychosocial measures. Factorial validity was established with confirmatory factor analysis (CFA); omega and model-based internal consistency indexes were computed to examine the internal consistency of the scale. Convergent validity was established by correlating the KCCQ-23 scores with several clinical and psychosocial measures. Measurement invariance testing was conducted within a multigroup framework across patients with preserved vs those with reduced ejection fraction. Results Two CFA solutions were tested, which confirmed the theoretical and empirical models postulated by the original author. The internal consistency coefficients for the latent dimensions were adequate (Omega range =0.77-0.93; internal consistency coefficient =0.89-96)- KCCQ-23 scores were found to be correlated with ejection fraction, NYHA levels, quality of life, self-care confidence, anxiety and depression, and symptom burden, supporting its convergent validity. Finally, the KCCQ-23 was invariant across ejection fraction levels, both in the theoretical and empirical factor solution. Conclusion Overall, this study provides for the first time evidence that the KCCQ-23 has satisfactory psychometric properties, promoting its use in clinical settings and research to investigate the quality of life in patients with HF.

Psychometric properties of the KCCQ-12 in an european cohort of patients with heart failure

Abstract Background Despite medical advances, patients with heart failure continue to suffer from poor quality of life due to worsening symptoms and functional limitations. Therefore, it is important to understand the multidimensional facets of quality of life in these patients. The Kansas City Cardiomyopathy Questionnaire is a commonly used quality of life assessment tool worldwide. However, However, there is still a lack of knowledge about its psychometric properties. Purpose The aim of this study was to investigate the psychometric properties of the KCCQ-12 and its measurement invariance in a cohort of European patients with heart failure. Methods Participants (n=510, median age=72, IQR=18, 58% males) completed the KCCQ-12 alongside measures of clinical psychosocial severity. A confirmatory factor analysis was used to establish factorial validity; internal consistency was determined using the Omega coefficient and the model-based internal consistency coefficient. Zero-order correlations between the KCCQ-12 scores and clinical and psychosocial measures were performed to test convergent validity. Multigroup confirmatory factor analysis was conducted to test measurement invariance across patients with preserved vs reduced ejection fraction. Results Confirmatory factor analysis confirmed a four-factor solution, with the domains of physical limitations, symptom frequency, quality of life, and social interference. Internal consistency was excellent (Omega coefficients ranging from 0.83 and 0.90, and internal consistency index of 0.94). The KCCQ-12 scores significantly correlated with ejection fraction, New York Heart Association class, quality of life, anxiety, depression, symptom burden, and the KCCQ-23 Overall Summary score, which adequately supported the convergent validity of the KCCQ-12. Measurement invariance was confirmed at the partial scalar and strict level. Conclusions These findings support the validity and reliability of the KCCQ-12, both in patients with reduced and preserved ejection fraction. Hence, this version can be confidently used both in research and clinical practice to measure quality of life of heart failure patients.

Multifactorial Memory Questionnaire: a comparison of young and older adults

ABSTRACT The Multifactorial Memory Questionnaire (MMQ; Troyer & Rich, [2002]. Psychometric properties of a new metamemory questionnaire for older adults. The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 57(1), P19–P27) is a widely used measure of subjective memory consisting of three scales: Satisfaction, Ability, and Strategies. Although subjective memory complaints are prevalent across different age groups, the factor structure and psychometric properties of the MMQ have yet to be examined in young adults. Here, we independently replicated the original MMQ factor structure in N = 408 young adults (YA) recruited from undergraduate courses and N = 327 older adults (OA) and, for the first time, assessed the age-invariance of the scale using measurement invariance testing. YAs made significantly higher ratings than OAs on MMQ-Satisfaction and MMQ-Strategies, indicating greater satisfaction with their memory and greater use of strategies, but the groups were similar on MMQ-Ability. The original MMQ factor structure was replicated in OAs but not in YAs, and age invariance was not supported. Future studies seeking to compare young and older adults could therefore consider either requesting modification of the MMQ for use with young adults or using a different scale.

Translation and psychometric properties of the Arabic version of the ageism scale for dental students (ASDS-Ar): A multi-institutional validation.

Ageism represents an important barrier to high-quality healthcare for older adults. The present study sought to translate and validate the Arabic version of the Ageism Scale for Dental Students (ASDS-Arabic). The 27-item ASDS tool was translated from English into Arabic following recommended cross-sectional forward and backward translation guidelines. The translated version was subjected to the content validity ratio (CVR) and sent to dental students in 21 institutes from 10 different Arab countries. Principal components analysis (PCA) was used to assess the dimensionality of the scale, and Cronbach's alpha was used to determine internal consistency reliability. The discriminant validity of the scale was assessed using the independent t-test. Confirmatory factor analysis (CFA) was also undertaken. Based on CVR, three items were removed. The 24-item Arabic version was completed by 3284 dental students. PCA and CFA retained 17 items in six components, explaining 50.3% of the total variance, with acceptable reliability, validity and discrimination. The first component "Adherence of older patients with dental treatment and instructions," included four items with a Cronbach α of 0.64 and scored 4.3 ± 0.8. The second component "Feasibility of the treatment plan," included three items with a Cronbach α of 0.66 and scored from 2.6 ± 1.2 to 2.9 ± 1.1. The third component "Cost of and responsibility for the dental treatment" included four items with a Cronbach α of 0.47 and scored 4.4 ± 0.8 to 4.5 ± 0.8. The fourth component "Medical history of older patients" included two items with a Cronbach α of 0.70 and scored 4.0 ± 1.0 to 4.1 ± 1.0. The fifth Component "Feeling towards older patients" included two items with a Cronbach α of 0.672 and scored 2.6 ± 1.2 to 2.0 ± 1.4. The sixth Component "Confidence and experience in treating older patients" included two items with a Cronbach α of 0.33 and scored 4.4 ± 1 to 4.6 ± 1. This preliminary validation of the ASDS-Ar resulted in a new 17-item scale with six components with acceptable validity, reliability and discrimination.

Validation of the Interpersonal Relationships in Eating Disorders (IR-ED) Scale in an Eating Disorder Sample.

Interpersonal problems have been identified as a plausible mechanism underlying the onset and maintenance of eating disorders. The Interpersonal Relationships in Eating Disorders (IR-ED) scale is the first eating disorders-specific measure of interpersonal problems, which was developed in a nonclinical sample. The aims of the current study were to (a) confirm the factor structure of the IR-ED within a large clinical sample, (b) investigate measurement invariance of the IR-ED across nonclinical and clinical samples, (c) examine the convergent validity of the IR-ED using a generic measure of interpersonal problems, and (d) investigate the incremental clinical utility of the IR-ED in uniquely predicting eating disorder symptomatology. Treatment-seeking individuals (N = 437) completed the IR-ED at their initial assessment appointment at a specialist eating disorder outpatient service. A multiple-group confirmatory factor analysis supported an invariant bifactor structure comprising a general interpersonal problems factor and two group factors-Avoidance of Body Evaluation and Food-Related Interpersonal Tension. Convergent validity was demonstrated by a large, statistically significant correlation with a generic measure of interpersonal problems (r = 0.62, p < 0.001). A series of structural equation models further revealed unique incremental predictive utility of the IR-ED for eating disorder symptomatology. The IR-ED has strong psychometric properties and may prove beneficial in the assessment, formulation, and treatment of eating-specific interpersonal problems among patients with eating disorders.

The Knowledge, Attitudes, and Practices of Healthy Eating Questionnaire: a pilot validation study in Chinese families

IntroductionIdentifying the knowledge, attitudes, and practices (KAP) gaps of healthy eating can inform the design of effective interventions. This study aimed to test the validity and psychometric properties of a KAP of Healthy Eating Questionnaire (KAP-HEQ) tailored to the Chinese culture.MethodsThe dimensions and potential items of each KAP scale were identified from published KAP and health literacy questionnaires, which were supplemented by the findings of a previous qualitative healthy eating study. Content validity of the KAP-HEQ was evaluated by eight experts and eight Chinese parent–adolescent dyads in Hong Kong through content validity ratio (CVR), content validity index (CVI), and qualitative feedback. The feasibility, construct validity, reliability, and sensitivity of the KAP-HEQ were evaluated in this pilot study among 60 adolescent–parent dyads (120 persons) through an online survey. The first 30 dyads who completed the KAP-HEQ were invited to repeat the KAP-HEQ 2 weeks later to assess the test–retest reliability.ResultsThe final 44-item KAP-HEQ was completed in 10–15 min by both adolescents and their adult parents. The CVR ranged from −0.38 to 1, and the CVI ranged from 0.56 to 1. Over 80% of the items achieved convergent validity (a significantly positive correlation with its hypothesized scale) and discriminant validity (a higher correlation with its hypothesized scale than with the other two scales). Cronbach’s alpha for the internal consistency of the Overall, Attitude, and Practice scales was &amp;gt;0.7, while that of the Knowledge scale was 0.54. The intraclass correlation coefficient (ICC) on test–retest reliability of the Overall and individual scales were all &amp;gt;0.75 except that of the Knowledge scale (ICC = 0.58). The significant differences in KAP scale scores with small to large effect sizes were found between known groups as hypothesized, except the Attitude score between groups by household income, which supported the sensitivity of the KAP-HEQ.ConclusionThe KAP-HEQ has shown good validity, reliability, and sensitivity among Chinese adolescents and adults, which can be applied to evaluate KAP status and gaps to inform the design and assess the effectiveness of healthy eating interventions.

Psychometric properties of the knowledge and understanding questionnaire of the canadian assessment of physical literacy-2 in low-income brazilian children

This study aimed to translate and cross-culturally adapt the Physical Literacy Knowledge (PLK) questionnaire from Canadian Assessment of Physical Literacy-2 for Portuguese version, and to evaluate its psychometric properties (construct validation, content, composite reliability, measurement invariance) in low-income Brazilian children. The sample comprised of 562 children (247 girls), aged between 8.00 and 12.99 years-old (10.20±1.20 years), enrolled in the 12 public-school in Lagoa do Carro city, Pernambuco, Brazil. A translation and cross-cultural adaptation of the PLK questionnaire was carried out. Content validity was determined by calculating the content validity coefficient, which assesses the relevance, clarity and pertinence of total (CVCt) and each question individually (CVCi). The dimensional structure of the PLK and alternative models were considered with first and second order models. Internal consistency was assessed using composite reliability. Structural invariance (configural, metric, scalar and strict) between sexes was also assessed using a multigroup factor analysis. Content validity was considered acceptable, varying between 0.88 and 1.00 for CVCi, and 0.91, 0.94 and 0.99 for clarity, pertinence and relevance in the CVCt, respectively. Construct validity was considered adequate, with 3 dimensions and 9 items model being the most appropriate [χ²(df)=34.01(24); CFI=0.92; TLI=0.87; RMSEA=0.03; SRMR=0.04; 90%CIRMSEA=0.00-0.05]. The questionnaire was structurally invariant (all ΔCFI&lt;0.05). Based on the findings, the PLK questionnaire has adequate psychometric properties to assess the cognitive domain of Physical Literacy in low-income Brazilian children. Key-words: Physical Literacy; Cognition; Children; Psychometry; Child Development.

Death anxiety scale (DAS): internal structure and factorial invariance in Peruvian adults

Background Studies have this reported the presence of death anxiety, ranging from near-death experiences to physically ill people, to a simple thought about death, as well as when it is associated with states of loneliness. The Templer’s Death Anxiety Scale (DAS), based on Eysenk’s incubation theory, has been adapted and validated in different contexts and is still insufficient in countries such as Peru. This study aimed to determine the psychometric properties of the DAS, its internal structure, and factorial invariance. Methods An online scale was used in 1248 Peruvians aged between 18 and 70 years (M= 27.37, SD= 11.29) from all regions. DAS was validated using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, measurement invariance, and internal consistency (reliability). Results Psychometric properties were found with adequate values in its structure and validity based on the internal structure through exploratory factor analysis, where it was found that the components of the scale are interrelated and the data matrix is factorizable. model of three specific factors and a general factor is presented, which is consistent with the theory and has practical utility, revealing adequate statistical values that reflect acceptable levels of reliability. Finally, there was fairness according to sex and age group of the scale by means of factorial invariance analysis. Conclusions Our results indicate adequate psychometric properties and facilitate a better data collection process for future research.

Validation of the Maslach Burnout Inventory-General Survey 9-item short version: psychometric properties and measurement invariance across age, gender, and continent

BackgroundThe Maslach Burnout Inventory-General Survey (MBI-GS) stands as the preeminent tool for assessing burnout across various professions. Although the MBI-GS9 emerged as a derivative of the MBI-GS and has seen extensive use over several years, a comprehensive examination of its psychometric properties has yet to be undertaken.MethodsThis study followed the Standards for Educational and Psychological Testing guidelines to validate the MBI-GS9. Employing a combined approach of classical test theory and item response theory, particularly Rasch analysis, within an integrated framework, the study analyzed data from 16,132 participants gathered between 2005 and 2015 by the Centre for Organizational Research at Acadia University.ResultsThe findings revealed that the MBI-GS9 exhibited satisfactory reliability and validity akin to its predecessor, the MBI-GS. Across its three dimensions, Cronbach’s α and omega coefficients ranged from 0.84 to 0.91. Notably, the MBI-GS9 displayed no floor/ceiling effects and demonstrated good item fit, ordered threshold, acceptable person and item separation and reliability, clear item difficulty hierarchy, and a well-distributed item threshold. However, the results suggested a recommended minimum sample size of 350 to mitigate potential information loss when employing the MBI-GS9. Beyond this threshold, the observed mean difference between the MBI-GS and MBI-GS9 held minimal practical significance. Furthermore, measurement equivalence tests indicated that the MBI-GS9 maintained an equivalent three-factor structure and factor loadings across various gender, age, and continent groups, albeit with inequivalent latent values across continents.ConclusionIn sum, the MBI-GS9 emerges as a reliable and valid alternative to the MBI-GS, particularly when utilized within large, diverse samples across different age and gender demographics. However, to address potential information loss, a substantial sample size is recommended when employing the MBI-GS9. In addition, for cross-cultural comparisons, it is imperative to initially assess equivalence across different language versions at both the item and scale levels.
