AbstractBackgroundIn the Arab countries, there has not been yet a specific validated questionnaire that can assess the psychological antecedents of COVID-19 vaccine among the general population. This study, therefore, aimed to translate, culturally adapt, and validate the 5C scale into the Arabic language.MethodsThe 5C scale was translated into Arabic by two independent bilingual co-authors, and then subsequently translated back into English. After reconciling translation disparities, the final Arabic questionnaire was disseminated into four randomly selected Arabic countries (Egypt, Libya, United Arab Emirates (UAE), and Saudi Arabia). Data from 350 Arabic speaking adults (aged ≥18 years) were included in the final analysis. Convergent, discriminant, exploratory and confirmatory factor analyses were carried out. Internal consistency was assessed by Cronbach alpha.ResultsAge of participants ranged between 18 to 73 years; 57.14% were females, 37.43% from Egypt, 36.86%, from UAE, and 30% were healthcare workers. The 5 sub-scales of the questionnaire met the criterion of internal consistency (Cronbach alpha ≥0.7). Convergent validity was identified by the significant inter-item and item-total correlation (P<0.001). Discriminant validity was reported as inter-factor correlation matrix (<0.7). Exploratory factor analysis indicated that the 15 items of the questionnaire could be summarized into five factors. Confirmatory factor analysis confirmed that the hypothesized five-factor model of the 15-item questionnaire was satisfied with adequate psychometric properties and fit with observed data (RMSEA=0.060,GFI=0.924, CFI=0.957, TLI=0.937, SRMR=0.076 & NFI=906).Conclusionthe Arabic version of the 5C scale is a valid and reliable tool to assess the psychological antecedents of COVID-19 vaccine among Arab population.

Background In the Arab countries, there has not been yet a specific validated Arabic questionnaire that can assess the psychological antecedents of COVID-19 vaccine among the general population. This study, therefore, aimed to translate, culturally adapt, and validate the 5C scale into the Arabic language. Methods The 5C scale was translated into Arabic by two independent bilingual co-authors, and then translated back into English. After reconciling translation disparities, the final Arabic questionnaire was disseminated into four randomly selected Arabic countries (Egypt, Libya, United Arab Emirates (UAE), and Saudi Arabia). Data from 350 Arabic speaking adults (aged ≥18 years) were included in the final analysis. Internal consistency was assessed by Cronbach’s alpha. Construct validity was determined by concurrent, convergent, discriminant, exploratory and confirmatory factor analyses. Results Age of participants ranged between 18 to 73 years; 57.14% were females, 37.43% from Egypt, 36.86%, from UAE, 30% were healthcare workers, and 42.8% had the intention to get COVID-19 vaccines. The 5 sub-scales of the questionnaire met the criterion of internal consistency (Cronbach’s alpha ≥0.7). The predictors of intention to get COVID-19 vaccines (concurrent validity) were young age and the 5C sub-scales. Convergent validity was identified by the significant inter-item and item-mean score of the sub-scale correlation (P<0.001). Discriminant validity was reported as inter-factor correlation matrix (<0.7). Kaiser-Meyer-Olkin sampling adequacy measure was 0.80 and Bartlett’s sphericity test was highly significant (P<0.001). Exploratory factor analysis indicated that the 15 items of the questionnaire could be summarized into five factors. Confirmatory factor analysis confirmed that the hypothesized five-factor model of the 15-item questionnaire was satisfied with adequate psychometric properties and fit with observed data (RMSEA = 0.060, GFI = 0.924, CFI = 0.957, TLI = 0.937, SRMR = 0.076 & NFI = 906). Conclusion The Arabic version of the 5C scale is a valid and reliable tool to assess the psychological antecedents of COVID-19 vaccine among Arab population.

Abstract Background: The Mini-Mental Adjustment to Cancer Scale (Mini-MAC) instrument is commonly used worldwide by professionals of oncology, but the scale has not, up to date, been validated in Arabic and Moroccan context, and there is absence of data in the Moroccan population. This study aims to validate the Mini-MAC, translated and adapted to the Arabic language and Moroccan culture, in women with breast cancer.Methods: The Mini-MAC instrument was administered to 203 breast cancer women, receiving medical care in the university Hospital of Fez city. A cross-sectional validation study using exploratory factor analysis and Confirmatory factor analysis was carried out.Results: Confirmatory factor analysis confirmed Watson’s original structure underlying the Mini-MAC items: Helpless/Hopeless, Anxious Preoccupation, Fighting Spirit, Cognitive Avoidance, and Fatalism. Absolute, incremental, and parsinmonious fit indices showed a high significant level of acceptance confirming a good performance of the measurement model. The instrument showed sufficient reliability and convergent validity demonstrated by acceptable values of composite reliability (CR =0.93–0.97), and average variance extracted (AVE= 0.66 - 0.93), respectively. The square roots of AVE were higher than factor-factor pairs correlations, and the Heterotrait-Monotrait ratio of correlations values were lesser than 0.85, indicating an acceptable discriminant validity. Conclusions: reliability; and both convergent and discriminant validity tests indicated that The Arabic version of the Mini-MAC had a good performance and may serve as a valid tool measuring psychological responses to cancer diagnosis and treatment.

This study aims to validate the Mini-MAC, translated and adapted to the Arabic language and Moroccan culture, in women with breast cancer. Methods Data were analyzed in two successive phases. First, exploratory factor analysis (EFA) was used to assess the factor structure in the pilot sample (N = 158). Then, this structure was confirmed in the validation sample (N = 203) using confirmatory factor analysis (CFA). Results Confirmatory factor analysis confirmed Watson’s original structure underlying the Mini-MAC items: Helpless/Hopeless, Anxious Preoccupation, Fighting Spirit, Cognitive Avoidance, and Fatalism. Absolute, incremental, and parsimonious fit indices showed a highly significant level of acceptance confirming a good performance of the measurement model.

Objective This study was performed to assess the reliability and validity of the Chinese version of the Snizek-revised Hall’s Professionalism Inventory Scale (C-SR-HPIS). Methods Exploratory factor analysis and confirmatory factor analysis were used to evaluate the construct validity of the C-SR-HPIS. The average variance extracted (AVE) and square root of the AVE were calculated and correlation analyses were performed to test the convergent validity and discriminant validity, respectively. Cronbach’s alpha (α) coefficient was used to test the internal consistency reliability. Results Data for 355 clinical nurses in mainland China were collected. Five factors were extracted, accounting for 58.86% of the total explained variance, and 20 items were selected for the C-SR-HPIS. The confirmatory factor analysis suggested good fitness of the modified model. The AVE was acceptable for convergent validity. The square roots of the AVE of the five factors were larger than their correlation coefficients with other factors, showing suitable discriminant validity. Cronbach’s α coefficient of internal consistency reliability of the overall scale was 0.76, indicating good reliability of the scale. Conclusions This study demonstrated good reliability and validity of the C-SR-HPIS and provides a quantitative tool for the assessment of nursing professionalism in China.

The study aimed to perform confirmatory factor analysis, internal consistency, gender differential item functioning, and discriminant validity of the Fear of COVID-5 Scale in emerging adult students of a university in Mexico. Confirmatory factor analysis, internal consistency (Cronbach's alpha and McDonald's omega), and gender differential item functioning were estimated (Kendall tau b correlation). The Fear of COVID-5 Scale showed a one-dimension structure (RMSEA = 0.07, CFI = 0.98, TLI = 0.96, and SRMR = 0.02), with high internal consistency (Cronbach's alpha of 0.78 and McDonald's omega of 0.81), non-gender differential item functioning (Kendall tau b between 0.07 and 0.10), and significant discriminant validity (Higher scores for fear of COVID-19 were observed in high clinical anxiety levels). In conclusion, the Fear of COVID-5 Scale presents a clear one-dimension structure similar to a previous study.

Background: Sensory integration is a necessary skill for acquiring reading skills because it strongly depends on the rapid and strong relation between written and verbal symbols. There is no standardized test for Iranian children with dyslexia to investigate their sensory processing problems. Therefore, understanding the validity and reliability of the child sensory profile 2 (CSP2) would be essential for a detailed assessment of sensory impairments in dyslexic children. Objectives: The current research aimed to establish the internal consistency, factor analysis, and convergent validity of the Persian version of CSP2 in children with dyslexia. Methods: The sample of this study included 200 dyslexic children aged 6 to 12 years who were referred to learning disabilities centers in Qom from September 2019 to February 2020 by using the multistage sampling method. To collect data, the CSP2 questionnaire and the dyslexia test (NEMA) were used. The factor structure was assessed by confirmatory factor analysis. The internal consistency of the CSP2 was examined by using Cronbach’s alpha. Convergent validity was assessed by examining the relationship between CSP2 and NEMA. Results: Internal consistency was obtained as 0.89, 0.92, 0.77, and 0.94 for the four subscales of sensory processing, namely registration, seeking, sensitivity, and avoiding, respectively. The result of confirmatory factor analysis gained support for Dunn's four-factor model. Total scores of NEMA were correlated with the scores of CSP2 subscales (seeking, avoiding, sensitivity, and registration). Conclusions: The Persian version of the Child Sensory Profile 2 is a valid (via confirmatory factor analysis and convergent validity) and reliable (via internal consistency) tool for assessing sensory processing in children with dyslexia.

Abstract Background Anxiety and depression symptoms are common among cardiac patients. The Hospital Anxiety and Depression Scale (HADS) is frequently used to measure symptoms of anxiety and depression; however, no study on the validity and reliability of the scale in Danish cardiac patients has been done. The aim, therefore, was to evaluate the psychometric properties of HADS in a large sample of Danish patients with the four most common cardiac diagnoses: ischemic heart disease, arrhythmias, heart failure and heart valve disease. Methods The DenHeart study was designed as a national cross-sectional survey including the HADS, SF-12 and HeartQoL and combined with data from national registers. Psychometric evaluation included analyses of floor and ceiling effects, structural validity using both exploratory and confirmatory factor analysis and hypotheses testing of convergent and divergent validity by relating the HADS scores to the SF-12 and HeartQoL. Internal consistency reliability was evaluated by Cronbach’s alpha, and differential item functioning by gender was examined using ordinal logistic regression. Results A total of 12,806 patients (response rate 51%) answered the HADS. Exploratory factor analysis supported the original two-factor structure of the HADS, while confirmatory factor analysis supported a three-factor structure consisting of the original depression subscale and two anxiety subscales as suggested in a previous study. There were floor effects on all items and ceiling effect on item 8. The hypotheses regarding convergent validity were confirmed but those regarding divergent validity for HADS-D were not. Internal consistency was good with a Cronbach’s alpha of 0.87 for HADS-A and 0.82 for HADS-D. There were no indications of noticeable differential item functioning by gender for any items. Conclusions The present study supported the evidence of convergent validity and high internal consistency for both HADS outcomes in a large sample of Danish patients with cardiac disease. There are, however, conflicting results regarding the factor structure of the scale consistent with previous research. Trial registration ClinicalTrials.gov: NCT01926145.

Abstract Background The transition out of military service and subsequent reintegration to civilian life has been established as a period associated with an increased risk of psychological adjustment difficulties, psychiatric disorders and suicide risk, yet no tool exists to measure cultural and psychological adjustment following permanent separation from the military. This study describes the two-phase mixed-methods development and validation of the self-report Military-Civilian Adjustment and Reintegration Measure (M-CARM). Methods In Phase I, four focus groups (n = 20) and semi-structured one-on-one interviews (n = 80) enabled thematic analysis and generation of 53 initial items that were reviewed by an expert multidisciplinary panel (n = 12) and piloted for clarity and relevance in an Australian service-veteran sample (n = 11). In Phase II, psychometric properties of the 47 items resulting from Phase I were evaluated with online assessment of a convenience sample of transitioned Australian Defence Force veterans (n = 725). Analyses included exploratory and confirmatory factor analyses, as well as evaluation of test-retest reliability, internal consistency, and convergent, divergent and discriminant validity. Results Exploratory factor analysis on a randomized split-half sample (n = 357), resulted in a 21-item, five-factor solution of Purpose and Connection, Help seeking, Beliefs about civilians, Resentment and regret, and Regimentation, explaining 53.22% of the variance. Confirmatory factor analysis (n = 368) verified this factor structure without modification (χ2 = 304.96, df = 160; CFI = .96, TLI = .94, NFI = .91, RMSEA = .05). Strong convergent, divergent and discriminant validity was demonstrated as M-CARM scores significantly correlated with related constructs assessed by standardised clinical measures as well as differentiated groups based on three binary reintegration items, with large effect sizes (d = > 1). Strong test-retest reliability for the total score (n = 186, r = .93) and excellent internal consistency (n = 725, a = .90) were also found. Conclusions Results provide promising evidence the M-CARM is a valid, reliable measure of psychological and cultural reintegration to civilian life, with potential for considerable clinical and research application.

The purpose of this study is to conceptualize a construct of Tour Conductor Playfulness (TCP) and establish a set of reliable and valid measures for TCP. The construct of TCP introduces a new concept in tourism research, while also extending the application of playfulness theory. TCP also can help businesses train employees and serve as a tool for human resource management. Study 1 produced initial items through in-depth interviews and content analysis, and study 2 conducted two sample collections. First, an exploratory factor analysis was performed by investigating 253 tour conductors, and four factors were identified: playful guiding, enthusiastic guiding, creative guiding, and engaged guiding. Second, this scale was validated with a new sample of 396 tour conductors. We verified the reliability of the TCP scale through confirmatory factor analysis, convergent validity, and discriminant validity to finally obtain 23 items. Implications and suggestions for future research are provided.

Purpose Standardized clinical assessment of dysarthria is essential for management and research. We present a new, fully standardized dysarthria assessment, the Bogenhausen Dysarthria Scales (BoDyS). The measurement model of the BoDyS is based on auditory evaluations of connected speech using 9 scales (traits) assessed by 4 elicitation methods. Analyses of the BoDyS' reliability and construct validity were performed to test this model, with the aim of gauging the auditory dimensions of speech impairment in dysarthria. Method Interrater agreement was examined in 70 persons with dysarthria. Construct validity was examined in 190 persons with dysarthria using a multitrait-multimethod design with confirmatory factor analysis. Results Interrater agreement of < 1 on a 5-point scale was found in 91% of cases across listener pairs and scales. Average reliability was .85. Inspection of the multitrait-multimethod matrix pointed at a high convergent and discriminant validity. Modeling of the BoDyS trait and method factors using confirmatory factor analysis yielded high goodness of fit. Model coefficients confirmed high discriminant and convergent validity and revealed meaningful relationships between scales and methods. Conclusions The 9 auditory scales of the BoDyS provide a reliable and valid profile of dysarthric impairment. They permit standardized measurement of clinically relevant dimensions of dysarthric speech.
