This study aimed to generate a linguistic equivalent of the COVID Stress Scales (CSS) in the Serbian language and examine its psychometric characteristics. Data were collected from September to December 2020 among the general population of three cities in Republic of Serbia and Republic of Srpska, countries where the Serbian language is spoken. Participants completed a socio-demographic questionnaire, followed by the CSS and Perceived Stress Scale (PSS). The CSS was validated using the standard methodology (i.e., forward and backward translations, pilot testing). The reliability of the Serbian CSS was assessed using Cronbach’s alpha and McDonald’s omega coefficients and convergent validity was evaluated by correlating the CSS with PSS. Confirmatory factor analysis was performed to examine the construct validity of the Serbian CSS. This study included 961 persons (52.8% males and 47.2% females). The Cronbach’s alpha coefficient of the Serbian CSS was 0.964 and McDonald’s omega was 0.964. The Serbian CSS with 36 items and a six-factorial structure showed a measurement model with a satisfactory fit for our population (CMIN/DF = 4.391; GFI = 0.991; RMSEA = 0.025). The CSS total and all domain scores significantly positively correlated with PSS total score. The Serbian version of the CSS is a valid and reliable questionnaire that can be used in assessing COVID-19-related distress experienced by Serbian speaking people during the COVID-19 pandemic as well as future epidemics and pandemics.

Abstract Background: Parents of children with autism spectrum disorder (ASD) are known to poorer quality of life. The Quality of Life in Autism Questionnaire (QoLA) is a commonly used instrument for measuring the quality of life in parents of children with ASD. The aim of this study was to evaluate the reliability and validity of the QoLA in Iranian mothers of children with ASD.Methods: The sample of this methodological study consisted of 88 mothers of children with ASD in Arak, Iran. The data were collected using convenience sampling method between September 2019 and January 2020. A battery of questionnaires was administered to mothers which included the QoLA, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale-4 (PSS-4). Factor structure and internal consistency of the QoLA were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with WHOQOL-BREF, PHQ-9, GAD-7 and PSS-4.Results: The mean total scores of QoLA Part A and Part B were 86.50 (SD=13.89) and 61.41 (SD=18.21), respectively. Both subscales exhibited good internal validity (with Cronbach’s alpha of 0.899 and 0.950 for Part A and Part B, respectively). The convergent validity of both subscales of QoLA was proved via moderate to strong correlations with measure of the WHOQOL-BREF. In addition, both QoLA Part A and Part B scores were negatively correlated with measures of PHQ-9, GAD-7, and PSS-4. The confirmatory factor analyses provided evidence for unidimensionality of both subscales of QoLA.Conclusion: The Persian version of QoLA displays satisfactory reliability and validity in Iranian mothers of children with ASD.

Background: Kinesiophobia is described as fear of physical movement resulting in painful injury. Older adults with knee osteoarthritis usually suffer from joint pain. Assessment of kinesiophobia is beneficial for prevention of further deterioration in performing activity. Even though, the Tampa Scale of Kinesiophobia (TSK-11) has been developed to briefly examine pain related to fear of movement in patients with chronic pain, the TSK-11 Thai version has not been examined for its validity and reliability yet. Objective: To examine psychometric properties of the TSK-11 Thai version. Materials and Methods: A cross-sectional study with 200 older people with knee osteoarthritis living in the northeastern part of Thailand was used in the present study. Participants were asked to complete the demographic questionnaire, the TSK-11-Thai version, the numeric rating scale (NRS), and the Pain Catastrophizing Scale (PCS) Thai version. To confirm the TSK-11 Thai version validity, construct validity was examined using confirmatory factor analysis. Pearson correlation coefficients were used to confirm the TSK-11-Thai version’s convergent validities. For internal consistency reliability, Cronbach’s alpha coefficients were also assessed. Results: The results of confirmatory factor analysis indicated that a two-factor model, including somatic factor and activity avoidance, fitted with the data. The TSK11-Thai version was positively correlated with pain catastrophizing. Cronbach’s alpha coefficients of the total TSK11-Thai version was at 0.77. For subscale, Cronbach’s alpha coefficients of the TSK somatic factor and activity avoidance were 0.61 and 0.69, respectively. Conclusion: The Thai version of TSK-11 has acceptable validity and reliability. The TSK-11-Thai version is suitable to use to examine pain-related fear of movement in patients with knee osteoarthritis for clinical and research purposes.

Background and Purpose: To establish the psychometric soundness for Coping and Adaptation Processing Scale (CAPS) using the Roy adaptation model as theoretical framework. Method: A descriptive, cross-sectional survey of a convenience sample of 199 nurses working in different acute health care facilities in California. The internal consistency of the multifactor CAPS questionnaire was explored using Cronbach’s alpha coefficient. Factors correlation was examined using Pearson product moment correlation. The factor structure was studied using confirmatory factor analyses. Results: In the confirmatory factor analysis, the indices of fitness highly supported these results. The Cronbach’s alpha coefficient for the total score was .81 and varied between .31 and .78 in the 5 domains. A positive and significant correlation emerged between CAPS factors and total scores (r = .91, p < .01) ranging from .17 to .81. CAPS showed acceptable validity and reliability for measuring the coping of nurses in acute setting. Future studies using the scale might lead to the improvement of the subscales measurement. Conclusion: The psychometric data suggests that CAPS is a highly suitable instrument to measure coping processes.

This study aims to investigate the construct validity and reliability of the checklist for qualitative analysis of the overhand serve in Volleyball. Fifty-five male subjects aged 13-17 years participated in the study. The overhand serve was analyzed using the checklist proposed by Meira Junior (2003), which analyzes the pattern of serve movement in four phases: (I) initial position, (II) ball lifting, (III) ball attacking, and (IV) finalization. Construct validity was analyzed using confirmatory factorial analysis and reliability through the Cronbach’s alpha coefficient. The construct validity was supported by confirmatory factor analysis with the RMSEA results (0.037 [confidence interval 90% = 0.020-0.040]), CFI (0.970) and TLI (0.950) indicating good fit of the model. In relation to reliability, Cronbach’s alpha coefficient was 0.661, being this value considered acceptable. Among the items on the checklist, ball lifting and attacking showed higher factor loadings, 0.69 and 0.99, respectively. In summary, the checklist for the qualitative analysis of the overhand serve of Meira Junior (2003) can be considered a valid and reliable instrument for use in research in the field of Sports Sciences.

This study develops a scale that assesses the self-efficacy of Sri Lankan nursing educators in assuming the roles of nursing educators and validates its psychometric properties. This methodological research followed the DeVellis Scale Development Model, which involves six steps of instrument development and evaluation. Preliminary items were determined through a literature review and focus group interviews with nine Sri Lankan nursing experts. The experts, comprising five South Korean and two Sri Lankan nursing professors, tested the scale’s content validity. Moreover, 15 nursing educators participated in a pilot study, and 126 educators took part in the main survey. To evaluate the scale’s validity and reliability, the data from a preliminary questionnaire were analyzed using SPSS/IBM and AMOS 24.0. Further, construct validity was tested using exploratory and confirmatory factor analyses, and reliability was tested by calculating Cronbach’s alpha and performing split-half testing. Finally, 39 items under four themes, “clinical mentorship” (18 items), “research” (10), “teaching” (6), and “advising” (5), explained 63.5% of the total variance. Confirmatory factor analysis results revealed an acceptable model fit for the final scale. The developed scale achieved a Cronbach’s alpha value of 0.97. Thus, the psychometrical properties of the scale measuring Sri Lankan nursing educators’ self-efficacy were comprehensively evaluated and found acceptable. The developed scale will be useful in guideline development or studies regarding the self-efficacy of nursing educators’ roles in developing countries with similar context to Sri Lanka.
