Validity of Social Media Assessments in Personnel Selection

Abstract: Approximately two out of three recruiters report screening candidates’ KSAOs (knowledge, skills, abilities, and other characteristics like personality) or hireability based on social media platforms (e.g., Facebook, LinkedIn), often referred to as cybervetting. However, various researchers cautioned against engaging in this emerging practice due to questions about the validity of social media assessments. Therefore, we conducted a systematic review to summarize initial research on the psychometric properties of social media assessments: Reliability, construct-related validity, and criterion-related validity. Our literature search yielded 12 studies with 536 raters and 2,019 ratees, and most of these studies addressed personality traits. We found that single-rater reliability of social media assessments was mostly poor; convergent validity regarding personality traits was adequate, and criterion-related validity for job-related outcomes was small or close to zero. Convergent validity tended to be higher for ratings of extraversion and lower for neuroticism. However, given that evidence was scarce, we highlight that substantial gaps in the current state of knowledge about social media assessments remain. Thus, we conclude by discussing various avenues for future research to better understand and improve their validity.

An investigative study on the effective utilization of process hazard analysis (PHA) and safety instrumentation system (SIS) in chemical process industries

AbstractThis research paper focuses on effectiveness of process hazard analysis (PHA) and safety instrumented systems (SIS) interventions during process design and implementation which prevents accident and loss in chemical process industries. An initial preview was conducted to analyze the accidents and incidents in case of industrial and chemical process industries which enabled to define the research question in a scientific way. The research was conducted using a survey questionnaire developed with the help of focus group and was based on theoretical and conceptual framework developed for the study. The survey received responses from 36 participants who met the inclusion and exclusion criteria. The validity and reliability were established using confirmatory factor analysis, convergent validity, and Cronbach’s Alpha. The data analysis methods were used to answer the research questions to test the hypotheses. From the results it is observed that PHA and SIS were in an agreeable range. However, the performance factors grouped based on barrier controls and organizational behavior were have moderate positive relationship. This showed there exists a gap in the PHA and SIS contributing factors which may directly or indirectly cause industrial accidents in the chemical process industries.

Development and validation of an Arabic tool for assessment of post-vaccination confidence in COVID-19 vaccines (ARAB-VAX-CONF)

Abstract Background Vaccine confidence is described as a belief that vaccines are effective, safe, and part of a trustworthy health system. The objective of this study was to develop and validate an Arabic tool to evaluate confidence in the received coronavirus disease 2019 (COVID-19) vaccines (ARAB-VAX-CONF). Methods The research team developed the ARAB-VAX-CONF based on three areas specified by the Centers for Disease Control and Prevention (CDC): confidence in vaccine effectiveness, confidence in vaccine safety, and confidence in the healthcare system. The analysis includes data from 406 eligible vaccinated persons (≥ 18 years). Cronbach’s alpha was used to measure internal consistency, while convergent, discriminant, exploratory, and confirmatory factor analyses were used to verify construct validity. Results A total of 406 adults were recruited, with a mean age of 33.0 ± 12.2 years. A total of 63.1% were males, 56.7% were married, 21.9% had chronic conditions, 93.3% were nonsmokers, and 39.6% were obligated to obtain vaccines. The three domains of the scale met the criterion of internal consistency (Cronbach’s alpha > 0.7). Convergent validity was identified by the significant inter-item and item-mean score of the domain correlation (P < 0.001). Discriminant validity was reported as the inter-factor correlation matrix (< 0.7). The Kaiser–Meyer–Olkin sampling adequacy measure was 0.80, and Bartlett’s sphericity test was significant (P < 0.001). Exploratory factor analysis indicated that the scale could be summarized into three factors. Confirmatory factor analysis confirmed the adequate psychometric properties and fit with observed data (root-mean-square error of approximation = 0.08, comparative fit index = 0.945, Tucker-Lewis index = 0.924, standardized root-mean-square residual = 0.086, normed fit index = 0.918, and goodness-of-fit index = 0.909). Conclusions The ARAB-VAX-CONF developed in this study is valid and reliable for assessing confidence in vaccine effectiveness, safety, and confidence in the healthcare system. The ARAB-VAX-CONF can support decision-makers in addressing the gap in vaccine confidence among various populations.

Validation of the Coping with Children’s Negative Emotions Scale Adapted to the Early Childhood Education and Care Context

ABSTRACT Research Findings: The Coping with Children’s Negative Emotions Scale (CCNES) is a self-report instrument developed to measure parents’ emotion socialization with their children. This study examined the factorial and convergent validity of a short version of the CCNES adapted for the early childhood education and care (ECEC) context. Using exploratory factor analysis with responses from 490 ECEC-workers from the Oslo Early Education Study, our results revealed a three-factor structure of the CCNES, including emotion dismissing, emotion coaching, and emotion distracting. Model specifications were conducted in half the sample and cross-validated in the other half. ECEC-workers’ coaching and distracting correlated positively with each other and with their reports of supportive scaffolding practices and self-efficacy in supporting children’s socioemotional development. Dismissing correlated negatively with these measures. Practice and Policy. Our results indicate that this ECEC version of the CCNES is a valid instrument to assess ECEC-workers’ emotion socialization strategies in interactions with children and to support the use of distracting as a separate strategy. This instrument enables us to extend our knowledge of teacher–child interaction quality in ECEC by examining associations with children’s development. The CCNES could also form the baseline for discussions and reflections about ECEC-workers’ professional roles and development.

Psychometric properties of the Specific Phobia Dimensional Scale in an Australian adult community sample

ABSTRACT Objective The Specific Phobia Dimensional Scale (SP-D) is a 10-item scale developed by the Diagnostic and Statistical Manual (Fifth Edition) Anxiety, Obsessive-Compulsive Spectrum, Posttraumatic and Dissociative Disorder work group to supplement current categorical approaches to Specific Phobia (SP) assessment. The aim of the current study was to examine the psychometric properties of the SP-D in an Australian community sample. Method A total of 285 participants (74% female) aged 18–76 years (M = 28.15; SD = 12.01) completed the study. A smaller subsample (n = 18) completed the measures of interest a second time to examine test–retest reliability. Results Confirmatory factor analysis indicated a unidimensional factor structure of the SP-D (root mean square error of approximation [RMSE] = 0.13; comparative fit index [CFI] = 0.94). Internal consistency and test–retest reliability was high (a = 0.95 and Intraclass Correlation Coefficient [ICC] = 0.95, respectively). The measure demonstrated adequate convergent validity with the Specific Phobia Questionnaire (SPQ; r s = 0.54), and unsatisfactory divergent validity with the Fear Questionnaire – Agoraphobia subscale (FQ-Ag; r s = 0.45). Conclusions Overall, the findings suggest that the SP-D can reliably and briefly measure SP symptoms within an Australian community sample. Further research is required to investigate divergent validity. Replication of the test–retest results are required due to small sample size. Overall, this study is limited in its female-biased convenience sample and recruitment methodologies.

Cross-cultural validation of the Clinician-Administered PTSD scale for DSM-5, child and adolescent version in Japan

ABSTRACT Background: The establishment of a formal diagnosis of post-traumatic stress disorder (PTSD) for children and adolescents is the foundation for advancing pertinent clinical research and formulating proper treatment and management. However, a validated diagnostic tool for PTSD in children and adolescents is lacking in Japan. Objective: To examine the cross-cultural validity and reliability of the Japanese Clinician-Administered PTSD Scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), child and adolescent version (CAPS-CA-5-J). Method: Overall, 73 children who had experienced potentially traumatic events were recruited from three medical facilities. The linguistically validated CAPS-CA-5-J was conducted by trained psychiatrists and psychologists. Additionally, children and their caretakers completed questionnaires such as the UCLA PTSD reaction index for DSM-5 (PTSD-RI-5), Depression Self-Rating Scale for Children (DSRDC), and Strength and Difficulties Questionnaire (SDQ); 16 participants were randomly selected for the inter-rater reliability assessment. Results: Owing to missing values in the CAPS-CA-5-J and PTSD-RI-5, 68 children were included in the final analysis. Regarding reliability, the CAPS-CA-5-J showed excellent internal consistency (Cronbach’s alpha coefficient = 0.90) and interrater agreement (kappa coefficient = 0.88). Convergent validity was supported by a strong correlation between the total severity scale of the CAPS-CA-5-J and the PTSD-RI-5 scores (Pearson’s correlation coefficient = 0.82). Divergent validity was indicated by a moderate correlation between the CAPS-CA-5-J and DSRDC, and no correlation was found with the SDQ scores. Conclusions: This study is the first to validate a structured clinical interview for children and adolescents with PTSD in Japan. The psychometric properties of the CAPS-CA-5-J were good enough and comparable to those reported in previous validation studies. Therefore, the CAPS-CA-5-J can be considered reliable and valid for use in Japan.

Development of a revised version of the SCRAM questionnaire to evaluate sleep, circadian rhythms, and mood characteristics

ABSTRACT Sleep quality, chronotype, and mood may be closely interconnected processes. Typically, such constructs are measured independently, leaving out important information regarding their intrinsic relationships. The Sleep, Circadian Rhythms, and Mood (SCRAM) questionnaire is a promising tool for measuring sleep, chronotype, understood as diurnal preference, and depressive symptomatology, and the interrelationships between them. Anxiety has also been linked to sleep quality, chronotype, and depression, but there is currently no scale that measures these constructs together. This study aims to validate a revised version of the SCRAM questionnaire (rSCRAM), incorporating items to measure anxious mood. 486 Italian participants were involved in two studies. In Study 1, principal component analysis (PCA) identified representative anxiety elements from validated questionnaires. In Study 2, after adding the anxiety elements, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) established a 4-factor, 16-item model. The rSCRAM demonstrated excellent psychometric properties: high internal consistency (α = 0.72–0.90) and a strong test-retest reliability of the scales over 2 weeks (r = 0.73–0.82), a high correlation for convergent validity, and low correlations for divergent validity. The rSCRAM questionnaire measures the constructs for which it was created and revised. Including the anxiety scale enhances its utility in assessing mental health constructs within a single instrument.

Making plaque assessment easier - a validation study of simplified versions of the Marginal Plaque Index.

The assessment of plaque indices may be time-consuming and error-prone. Simplification of these indices may increase their utility without compromising their validity. The aim of this study was to evaluate the validity of two simplified versions of the Marginal Plaque Index (MPI). Two simplified versions of the MPI as well as the Plaque Control Record (PCR) were derived from full-scale MPI assessments in two studies with four age groups (N = 42 10-year-olds; N = 24 15 year-olds; N = 53 university students (18y-33y); N = 66 parents (32y-57y). Correlations with the Turesky modification of the Quigley-Hein Index (TQHI) and the Papillary Bleeding Index (PBI) were calculated. The indices derived from the MPI showed high convergence with each other (all r ≥ 0.94) and with the TQHI (r ≥ 0.80). The concurrent validity of the MPI with the PBI was equal to that of the TQHI in all age groups. The simplified versions of the MPI and the PCR show a lower convergent validity with the PBI than the MPI within parents (p < 0.05). In the other age groups, their convergent validity was equal to that of the MPI. Simplification of the MPI does not affect its convergent validity with other plaque indices but may reduce its concurrent validity with the PBI in middle-aged adults.

Psychometric Validation of the New Misophonia Screening List-Child and Youth and AMISOS-Y (Dutch Child- and Parent-Report Versions) for Assessing Misophonia in Youth.

Misophonia is a recently identified disorder of decreased sound tolerance that often originates in childhood. Currently, there is a lack of validated questionnaires for screening and assessing misophonia severity in children/adolescents. This paper presents an iterative validation process of two innovative (parallel child-/parent-reported) questionnaires: the Misophonia Screening List-Child and Youth for screening, and the Amsterdam Misophonia Scale-Youth (AMISOS-Y) for assessing misophonia severity in youth. After instrument refinement, we performed ROC curve, reliability, and principal component analyses, and assessed concurrent, convergent and divergent validity, on a combined sample (aged 8-18; clinical sample N = 94 youth, 95 parents; control group screening N = 197 youth, 56 parents; control group AMISOS-Y N = 192 youth, 55 parents). Both questionnaires were unidimensional and displayed excellent psychometric properties (α = 0.95-0.96). Future replication studies are needed in community and clinical samples to contribute to a unified diagnostic framework. Trial registered 09/2021: NL-OMON20775.

An Exploratory Study to Test the Psychometric Properties of Character Strengths-Semantic Differential Scale (CS-SDS) Among Singaporean Adults

Character strengths encompass a set of positive traits that can be manifested through thoughts, feelings, and behaviors. To measure the 24 character strengths, the Character Strengths-Semantic Differential Scale (CS-SDS) was used. The aim of the study was to (a) test the factor structure of CS-CDS and (b) test the convergent validity of CS-CDS with life satisfaction and positive affect, and the divergent validity of CS-SDS with negative affect. In total, 283 Singaporean students (96 males, 35.3%), with a median age of 24–26 years old (42.9%), participated in this study. Exploratory (EFA) and confirmatory factor analyses (CFA) showed the multi-dimensional nature of CS-SDS. Specifically, EFA demonstrated a four-factor model, while CFA identified a five-factor model, showing the dimensions of interpersonal, emotional, restraint, theological, and intellectual. All factors were significantly related to life satisfaction, positive affect, and negative affect. It was concluded that CS-SDS is a psychometrically sound instrument for measuring character strengths in the Asian context. This tool can be used for designing strength-based interventions aimed at promoting well-being and character among students in higher education.

Psychometric properties of an instrument to assess teachers’ practice of differentiated instruction (IATPDI): a confirmatory factor analysis on Bhutanese teachers’ data

IntroductionWe developed the IATPDI questionnaire, comprising seven scales for assessing teachers’ implementation of assessment methods, content, process, and product differentiation, familiarity with and use of various differentiated instruction (DI) strategies, factors influencing DI implementation, and resources used to enhance DI efficacy. This study examined the psychometric properties of the initial four scales with 35 items.MethodsThe questionnaire was administered to a sample of 237 Bhutanese teachers (66.2% male, 33.8% female), and confirmatory factor analysis (CFA) was used for psychometric evaluation.ResultsCFA supported the hypothesized four scales (CFI = 0.911, TLI = 0.903, SRMR = 0.052, RMSEA = 0.059, χ2/df = 1.58). Cronbach’s alpha coefficients ranged from 0.83 to 0.92, and Composite reliability (CR) ranged from 0.86 to 0.92, indicating high internal consistency reliability. Inter-factor correlations supported discriminant validity for most factor pairs, but correlations exceeding 0.85 between some pairs suggested potential overlap, prompting further investigation. Average Variance Extracted (AVE) values for assessment, content, process, and product factors were 0.50, 0.41, 0.53, and 0.51, respectively. While AVE for process and product factors surpassed the commonly accepted threshold (0.50) for convergent validity, the assessment factor approached the threshold and the content factor fell below it, indicating the need for further refinement of its indicators. However, all standardized factor loadings were significant (p &amp;lt; 0.05), confirming convergent validity.DiscussionThese results indicate that the proposed four scales of the IATPDI questionnaire are reliable and valid in measuring the intended constructs. Nevertheless, they also highlight the need for further refinement in identified areas to enhance the tool.

Psychometric Properties of the Malay Suicidal Behaviors Questionnaire-Revised (SBQ-R) in Malaysian Undergraduates

The psychometric properties of the Malay Suicidal Behaviors Questionnaire-Revised (SBQ-R) need to be tested as it is increasingly utilized, and there is a lack of a brief, validated scale to examine suicidal behaviors in Malaysia. A total of 713 and 715 undergraduates answered the English and Malay SBQ-R, respectively. Exploratory factor analysis derived a one-factor solution, with a total explained variance of 58.0% accounted for by the four items. Confirmatory factor analyses supported the one-factor model for the Malay SBQ-R, with acceptable fit indices (χ2/df = 0.451, comparative and Tucker–Lewis fit indices = ≥1.000, standardized root mean square residual = 0.014, root mean square error of approximation = 0.000, and 90% CI [0.000, 0.083]). Measurement invariance was achieved when comparing the SBQ-R between the English and Malay versions, indicating that both versions are similar in Malaysian undergraduates. Convergent validity was established through a strong correlation between the Malay SBQ-R and the Malay Yatt Suicide Attitude Scale (r = 0.74; p &lt; 0.001). Good internal consistency was achieved for both the English (α = 0.83; ω = 0.85) and Malay (α = 0.81; ω = 0.84) versions. The Malay SBQ-R has adequate validity and reliability for use in Malaysian undergraduates.

Abstract 4118724: Validity of a NYHA Classification Guide with Six Minute Walk Test Outcomes

Background: The New York Heart Association (NYHA) classification is a subjective tool that is commonly used in clinical practice to assess symptoms and functional capacity of patients with heart failure (HF). Correct assignment of NYHA is essential to facilitate evidence-based management. Research Question: What is the validity of the CLASS-HF Guide compared to the 6-minute walk test (6MWT)? Purpose: To examine the validity of the new investigator-developed CLASS-HF guide to assist in appropriate assignment of NYHA Class relative to the 6MWT. Methods: A multi-site, cross-sectional study in three cardiology clinical sites (two specializing in HF) recruited 103 patients in various classes and stages of HF. Providers assigned patients their NYHA Classification using the CLASS-HF guide. Patients then performed the 6MWT with test staff blinded to the assigned NYHA class. Exertion, dyspnea, and walk distance were captured post-test. The validity of the guide-assisted classification was then examined for convergent validity with 6MWT outcomes. Data analysis was performed with correlations, ANOVA, and multivariable regression. Results: Of the 103 total participants, 65.1% were male, 18.4% were non-White, with an average age of 66.0 ± 15.5 years old. A little less than one-third (30.1%) had HFpEF (LVEF ≥ 50%). Provider-assigned NYHA Class was 22.3% I, 38.8% II, 35.0% III and 3.9% IV. The average distance walked during the 6MWT by class was: 367.1 ± 85.6 m for I, 343.7 ± 104.7 m for II, 261.6 ± 73.9 m for III, and 184.6 ± 114.0 m for IV. Convergent validity of NYHA class with Borg exertion (Spearman’s r = .546, p &lt; .001) and dyspnea ( r = .504, p &lt; .001) was strong. A statistically significant inverse correlation was found between NYHA assigned class and meters walked during the 6MWT ( r = -.469, p &lt; .001), with significant mean differences (ANOVA F (3,99) = 10.72, p &lt; .001) in distance walked for: NYHA Class I vs. III ( md = 105.5 m), I vs. IV ( md = 182.6 m), II vs. III ( md = 82.1 m), II vs. IV ( md = 159.2 m). Increasing NYHA class remained significantly associated with lower 6MWT distance ( F (3,90)=5.22, p = .002) in multivariable regression (Adj. R -squared= .575) controlling for age, sex, race/ethnicity, diagnosis, site, Borg exertion and dyspnea, and 6MWT stopping/pausing. Conclusion: Validity evidence was found for NYHA class assignment after use of the CLASS-HF guide with respect to 6MWT distance and post-test perceived exertion and dyspnea.

Comparison of EQ-5D-Y-3L Utility Scores Using Nine Country-Specific Value Sets in Chinese Adolescents.

This study aimed to assess and compare the measurement properties of EQ-5D-Y-3L utilities derived from available countries' value sets (Chinese, Japanese, Slovenian, German, Spanish, Hungarian, Netherlandish, Belgian, and Indonesian), among Chinese adolescents. From July to September 2021, a large-scale cross-sectional survey was administered across 16 cities in Shandong, China, with the objective of assessing the health status of junior high school students aged 10-18 years. Supported by the educational authorities, quick response (QR) codes and questionnaire links were disseminated to schools. A total of 97,413 junior high school students completed the questionnaire. Agreement, convergent validity, and known-group validity were determined in the nine country-specific value sets. The Indonesian value set demonstrated the highest mean health utility score (0.970), followed by the Japanese (0.961), Chinese (0.960), Netherlandish (0.948), Hungarian (0.942), German (0.938), Belgian (0.932), Slovenian (0.926), and Spanish (0.926) value sets, respectively. The utility scores derived from Asian value sets were higher than those from Europe. Good or excellent agreements (intraclass correlation coefficients >0.7) were found between each paired value set. In Bland-Altman plots, the 95% limits of agreement for any two value sets were 0.046-0.348. A strong relationship (Spearman's correlation coefficients >0.99) between any two value sets was found. The EQ-5D-Y-3L utility scores discriminated equally well for the nine value sets across three known groups. The effect size and the relative efficiency statistics showed the Chinese value sets were more sensitive in general. Referring to the Chinese value set, all the relative efficiency values in each value set were similar across three known groups, ranging from 0.9 to 1.0. A total of nine country-specific EQ-5D-Y-3L value sets showed an overall high level of agreement, strong correlation, and good known-group validity. However, the utility scores derived from nine EQ-5D-Y-3L value sets were different and the country-specific value sets were not interchangeable.

Adaptation and validation of the Adolescent Psychotic-like Symptom Screener (APSS-6) in Spain: evidence from adult population.

Psychotic-like experiences are common in the general population and an important indicator of psychological vulnerability. One of the used instruments for their assessment is the Adolescent Psychotic-Like Symptom Screener (APSS). However, there are few studies on the APSS psychometric characteristics in different cultural contexts. The aim of this study is to adapt the instrument in the Spanish context and analyze its psychometric properties in an adult population. Upon the translation and adaptation of the APSS to Spanish, a sample of 287 participants (19-60 years) completed the questionnaire online together with the Symptom Assessment-45 Questionnaire (SA-45) and an ad-hoc survey on clinical and sociodemographic variables. The sample was then randomly split into two halves, the first being the calibration (n = 144) and the second the validation sample (n = 143). An exploratory factor analysis was performed with the former, and a confirmatory factor analysis was performed with the latter, together with internal consistency and convergent validity analyses. The APSS Spanish version presents a unifactorial structure comprising 6 out of the 7 original items with adequate fit and good internal consistency. This single factor structure is invariant across age, sex and history of self-reported psychopathology. The instrument also shows significant positive correlations with the SA-45 psychoticism and paranoid ideation subscales. To the best of our knowledge, this is the first study that has conducted a psychometric analysis of the APSS in adult population. The Spanish version of the APSS shows adequate reliability, construct and convergent validity in adults, therefore provides a handy tool to be used for the screening of psychotic-like experiences in the Spanish general population.

Construction of women's empowerment index for Bangladesh

IntroductionThis study is dedicated to refining and enhancing the measurement model of women's empowerment in Bangladesh. Women's empowerment, a crucial and multifaceted aspect of societal growth, is often hindered by gender disparities. This is particularly evident in societies like Bangladesh, where women face inequalities in education, economic opportunities, and decision-making power. To address these disparities effectively, it is essential to have a comprehensive understanding of women's empowerment. Therefore, this study aims to refine and enhance the measurement model to capture the multifaceted nature of women's empowerment accurately.MethodsTo gather data for this study, a structured questionnaire was administered to married women of reproductive age (15–49) in eight Mouza/Mohalla in Dhaka, Bangladesh. This unique approach allowed us to capture a diverse range of perspectives. We used thirty-three indicators across economic, socio-cultural, household, and psychological dimensions to measure women's empowerment. The sample data were then randomly divided for exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) to identify and validate a comprehensive multidimensional framework.ResultsOut of 625 respondents, only 36% of women worked, and ~39% married before age 18. Employing thirty-three items in EFA led to identifying eight critical factors (economic independence, control over household financial decisions, household decision-making, reproductive decision-making, freedom of movement, media exposure, positive self-esteem, and negative self-esteem). These factors, which explained 72.661% of the total variance in the data, provide a practical framework for understanding and addressing women's empowerment. Each component was then divided into two sub-dimensions to acquire a better understanding. The CFA indicated a good model fit for each dimension, and convergent and discriminant validity assessments were used to establish reliability and validity, further enhancing the practical implications of our findings.ConclusionsThe results of our rigorous exploratory and confirmatory factor analyses not only confirmed the sample structures and internal consistency but also provided significant insights. The findings suggested an adequate fit for all CFA models, indicating the robustness of our measurement model. According to the CFA results, each dimension's variables are satisfactory, and all the dimensions can be combined to create a single index measuring women's empowerment. This comprehensive understanding of women's empowerment, with its specific dimensions and factors, equips policymakers and practitioners with the knowledge to develop a wide range of interventions appropriate to particular facets of empowerment, thereby fostering societal growth and gender equality.

Assessment of psychometric properties of the Dari version of the Pittsburgh Sleep Quality Index (PSQI) among Afghans

Abstract Background Sleep helps in improving the functions of all systems of human body. Disturbance in sleep can cause immediate adverse effects on normal human physiologic functions. Main objective of this study was to explore the psychometric properties of the Dari version of the of Pittsburgh Sleep Quality Index (PSQI) among general adult population of Afghanistan. Methods This methodological study has been conducted during July to November 2023. Reliability and validity of PSQI were evaluated using Cronbach’s Alpha and confirmatory factor analysis, respectively. Pearson correlation analysis was conducted to assess the convergent validity of the components of PSQI, comparing results with those obtained from the DASS-21 subdomains. Results In this cross-sectional study, 965 Afghan adults were studied during five months of duration between July and November, 2023. Mean age of the study participants was 35.2 years. The prevalence of sleep disturbance was 44.6% (430/965). Among them, 59.3% (572/965) reported experiencing subjective sleep quality disturbances less than once a week, 36.2% (349/965) had sleep latency issues less than once a week, 17.6% (170/965) had sleep duration disruption once or twice a week, while 36.3% (350/965) had daytime dysfunction less than once a week. The Cronbach’s alpha coefficient for the seven-component scale was 0.677, indicating acceptable internal consistency. Substantial and statistically significant positive correlations were present among the component of PSQI subjective sleep quality and sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, daytime dysfunction, DASS-Depression, DASS-Anxiety, and DASS-Stress. The overall PSQI exhibited favorable fit indices, supporting the proposed single-factor structure among adult Afghan population. Conclusion Prevalence of sleep disturbance was very high among adult population of Afghanistan. This study provided useful information that will help policy makers (such as ministry of public health as well as international donor agencies like WHO, USAID, and UNICEF) to design a better strategy to reduce the prevalence of sleep disturbance that affects health of the Afghan community at large.

QOL-10. AN ASSESSMENT TOOL FOR MEASURING CAREGIVERS’ DEATH ANXIETY IN PRIMARY BRAIN TUMOR: A CONFIRMATORY FACTOR ANALYSIS

Abstract BACKGROUND Caregivers of patients with primary brain tumor describe significant emotional distress regarding their loved one’s impending trajectory and eventual mortality—a construct known as death anxiety. Our team adapted a pre-existing, validated scale for patients with advanced cancer (the Death and Dying Distress Scale; DADDS) to measure this latent variable in caregivers of patients with primary brain tumors. Our adapted scale (DADDS-CG) demonstrated preliminarily strong internal consistency and construct validity. We now seek to confirm the factor structure, internal consistency, and convergent validity of the DADDS-CG in a second sample of neuro-oncology caregivers in accordance with best practices of measure development. METHODS Caregivers of those with primary brain tumors (N=221) completed an online battery of self-report questionnaires, including the 15-item Death and Dying Distress Scale-Caregiving (DADDS-CG), the Generalized Anxiety Disorder (GAD-7), and the Patient Health Questionnaire (PHQ-9). To verify the two-factor structure of the DADDS-CG, we used confirmatory factor analysis. Cronbach’s alpha measured internal consistency, Pearson correlations assessed convergent validity, and descriptive statistics determined the prevalence of death anxiety. RESULTS Caregivers (Mage=46.2) were primarily White (85.5%) female (72.4%) spouses (75.6%). The two-factor model demonstrated adequate fit (X2/df=4.24; CFI-.89; NFI=.87; RMSEA=.06), suggesting two correlated subscales of death anxiety: Finitude and Dying (r=.80). The DADDS-CG demonstrated strong internal consistency (a=.95) and was moderately correlated with the GAD-7 (r=.73) and PHQ-9 (r=.68), suggesting adequate convergent validity. Mean scores fell within the moderate range (M=40.5, SD=18.7), with 20.8%, 36.2%, and 43.0% of caregivers reporting low, moderate, and severe death anxiety, respectively. CONCLUSION The DADDS-CG is a valid and reliable assessment tool for measuring death anxiety in caregivers of those with primary brain tumors. Given the high prevalence of death anxiety, future investigations are needed to understand caregiver’s death anxiety throughout the disease trajectory and to inform intervention development for neuro-oncology caregivers.

QOL-23. MEASURING BODY FUNCTIONALITY APPRECIATION IN PATIENTS WITH PRIMARY BRAIN TUMORS

Abstract BACKGROUND Body image is a multifaceted construct consisting of thoughts, feelings, and perceptions about one’s body and its functioning. Perception of one’s own physical functioning and capabilities may be an important consideration in neuro-oncology given the sequalae of brain tumors and associated treatment; however, it is understudied in this population. One brief measure of body image, the Functionality Appreciation Scale (FAS) is a comprehensive tool, focused on one’s perceived physical functioning and capabilities, rather than perceived appearance. We aimed to examine the psychometric properties of the recently developed Functionality Appreciation Scale (FAS) among patients with primary brain tumors. METHODS Adult patients with primary brain tumors (N=237) completed the FAS and other measures of psychological distress as well as medical and demographic characteristics. An exploratory variance factor analysis (EFA) using principal axis factoring and a Promax rotation was conducted. Convergent validity was examined via correlations to measures of psychological distress. RESULTS The EFA supported the single-factor structure, which accounted for 62.71% of the variance with all items loading significantly onto this factor. The FAS had good internal consistency (Cronbach’s a=.90). Convergent validity was demonstrated by negative associations (ps&amp;lt;.05) with symptoms of depression (r=-.30), generalized anxiety (r=-.21), and death anxiety (r=-.17). CONCLUSION Results confirmed the single factor structure of the FAS in primary brain tumor patients. Furthermore, the expected negative relationships with measures of psychological distress provide evidence of convergent validity. The FAS is valid and reliable in patients with primary brain tumors. Our findings suggest that body functionality and appreciation may be important to target in psychosocial interventions for those with primary brain tumors.

The Chinese version of the physical activity questionnaire for adolescents: a psychometric validity, reliability, and invariance study.

The Physical Activity Questionnaire for Adolescents (PAQ-A) is one of the most commonly used questionnaires for assessing adolescents' levels of moderate to vigorous physical activity (PA). Although a Chinese version of the PAQ-A (comprising nine items) exists, it has been assessed for only internal consistency coefficients, test-retest reliability, and correlations with the GT3X + accelerometer. Therefore, this study aimed to evaluate the psychometric properties of the Chinese version of the PAQ-A among Chinese adolescents. This study included three samples of 1,101 secondary school students (12-19years old). The first sample consisted of 518 participants (50.4% males, 49.6% females) for correlation tests and exploratory factor analysis (EFA). The second sample consisted of 227 participants (55.75% males, 44.24% females) for confirmatory factor analysis (CFA), convergent validity, and sample size invariance tests. The third sample consisted of 356 participants (54.50% male, 45.50% female) for the internal consistency reliability test, invariance test (cross sample size, education level and gender), and t-test. Pearson correlation analysis of the PAQ-A indicated that all the total-item correlations exceeded 0.2, indicating good consistency across the items. Subsequent EFA of the Chinese version of the PAQ-A revealed a two-factor structure. CFA subsequently validated this structure. One of the items exhibited a standardized loading below 0.4 and was excluded. The exclusion of this item resulted in increased standardized loadings for the remaining items, ranging from 0.40 to 0.82, which indicates improved fit indices. This adjustment underscores the questionnaire's satisfactory convergent validity and robust discriminant validity. The overall Cronbach's alpha was 0.821, with the values for the first and second factors being 0.757 and 0.716, respectively. The questionnaire demonstrated stable invariance across sample sizes and education levels and additionally showed partial scalar invariance across genders. A t-test revealed a significant difference between males and females, which aligns with previous findings. These findings supported the construct validity of the questionnaire. This study validated the Chinese version of the PAQ-A for assessing adolescent PA in China, with a two-factor structure improved by removing one item.
