The purpose of this study is to develop a Teachers' Autonomy on Curriculum Scale. For this aim, an item pool consisted of 50-item was prepared for the study. These scale items were reduced to 29 items after expert review and pilot implementation. This preliminary form was applied to 178 science teachers working in secondary schools in Izmir, Turkey. Validity and reliability studies have been done and Cronbach's Alpha internal consistency coefficient was calculated as .82. The scale is four-dimensional and reveals 67.4% of the total variance. The scale has four sub-scales (Professional Autonomy, Process Autonomy, Assessment Autonomy, and Planning Autonomy). Confirmatory factor analysis results support that the scale consisted of four subscales (RMSEA= .05, CFI= .98, AGFI= .89, RMR= .05, GFI= .93, SRMR= .06).

Abstract Background The Lederman Prenatal Self-Evaluation Questionnaire (PSEQ) is used to assess psychosocial adaptation to pregnancy, labor, childbirth, and maternity. The PSEQ is a tool used in various countries and has been translated into Portuguese; however, it needs to be validated in Brazil. This study aimed to analyze the validity and reliability of the PSEQ in Brazilian pregnant women. Method This methodological validity study investigated internal consistency and reliability using Cronbach’s alpha and intraclass correlation coefficients. Construct validity was assessed using Pearson’s correlation between domains and confirmatory factor analysis. To assess concurrent validity, Pearson’s correlation between the different domains of the PSEQ and Prenatal Psychosocial Profile-Portuguese Version (PPP-VP) was determined. The level of significance was set at 5%. Results This study included 399 pregnant women in the northeastern region of Brazil. The internal consistency and reliability of the total PSEQ score were high (Cronbach's alpha = 0.89; intraclass correlation coefficient = 0.95). Validity analysis showed positive and significant correlations between all PSEQ domains, ranging from 0.14 to 0.56. Confirmatory factor analysis demonstrated the following values of goodness of fit: RMSEA = 0.05, SRMR = 0.08, CFI = 0.61, χ2/df = 1.77. The discriminant and concurrent validities of the PSEQ were confirmed. Conclusions The Portuguese version of the PSEQ has adequate psychometric properties and is a valid and reliable tool to evaluate psychosocial adaptation to pregnancy in Brazilian pregnant women.

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.

The aim of this study is to adapt the Moral Integrity Scale developed by Sclenker (2008) to Turkish and conduct its psychometric analysis. The scale items were translated into Turkish by five specialists in the first place. After the language structure, culture suitability and understandability of the items were examined by the two experts, the items agreed upon were translated back to their original language by the two translation experts. After the positive evaluations of the experts, the final version of the scale items was decided. During the adaptation process of the study, data were collected from 470 people for exploratory factor analysis; from 248 people for confirmatory factor analysis and from 100 people for criterion validity. In this context, Exploratory Factor Analysis (AFA) was used to test the construct validity of the scale first. As a result of the exploratory factor analysis, it is seen that the moral integrity scale explains 52,127% of the variance as one dimension. Confirmatory factor analysis (CFA) was then performed to test the construct validity of the scale. The one-dimensional and 18-item structure of the Moral Integrity Scale was analyzed with DFA and accepted fit indices were obtained (X2 / sd = 2.745; p <.001; RMSEA = 0.061; S-RMR = 0.051; NFI = 0.929; CFI = 0.954; GFI = 0.915; RFI = 0.919). In order to calculate the scale reliability, the Cronbach Alpha (α) internal consistency coefficients and the difference between the lower and upper scores of 27% were examined. For the Moral Integrity Scale, the internal consistency coefficient Cronbach’s Alpha value was determined as 961. At the same time, the moral identity scale was used for criterion validity and a significant positive relationship was obtained with the two sub-dimensions of this scale. The total score obtained from the scale gives the person’s moral integrity score. According to all these results, it is understood that the Moral Integrity Scale has sufficient validity and reliability values.

Abstract Background: Self-management is the most important component in the treatment of chronic diseases, including multiple sclerosis (MS). The Bishop and Frain Multiple Sclerosis Self-Management Scale–Revised (MSSM-R) is one of the valid tools available for self-management assessment. The purpose of this study was to evaluate the psychometric properties of the MSSM-R in Iranian people with MS. Methods: This cross-sectional study was conducted in 2018 in the 1600 people with MS in Guilan Province, Iran. In this study, 250 people were selected by convenience sampling. The reliability of the Persian version of this scale was examined by internal consistency and test-retest methods, and validity evidence was evaluated using confirmatory factor analysis. Results: The MSSM-R had acceptable face and content validity. Confirmatory factor analysis results showed that 24 items on this scale have factor loadings in five subscales. Other results showed the internal consistency, as measured by Cronbach α and test-retest reliability, for the MSSM-R overall (α = 0.85, r = 0.77) and for the following subscales: Healthcare Provider Relationship and Communication (α = 0.83, r = 0.70), Treatment Adherence/Barriers (α = 0.70, r = 0.71), Social/Family Support (α = 0.79, r = 0.85), MS Knowledge and Information (α = 0.89, r = 0.72), and Health Maintenance Behavior (α = 0.77, r = 0.75). Conclusions: This study provides evidence of the validity and reliability of the MSSM-R. To further ensure its psychometric properties, additional studies with this scale are suggested.

Weight Stigmatization

The present study was intended to develop a scale to measure perceived weight stigmatization among people with obesity. The study was conducted in five steps. In first step, three focus group discussions were conducted with female obese university students to get the first-hand information related to weight stigmatization. Step two involved four interviews which were conducted with male obese university students to collect detailed information about weight stigmatization experiences of men. Step three included content analysis of qualitative data for item generation. In step four, judge’s opinion was taken, and a committee approach was carried out to select the items for the initial form of the scale. Items for final form of the scale were selected through exploratory factor analysis and confirmatory factor analysis in step five. For exploratory factor analysis, 150 university students (men = 61, women = 89) were included in the sample, whereas, for confirmatory factor analysis, another group of students (men = 78, women = 72) participated in the study. Principal Component Factor Analysis revealed three meaningful structures including Self-Perception, Perceived Social Rejection, and Perceived Impact containing 43 items. Confirmatory factor analysis confirmed this factor structure and all 43 items possessed factor loadings greater than .40. Moreover, results indicated that perceived weight stigmatization had high internal consistency (Cronbach’s alpha = .96) with three subscales having internal consistency .95, .83, and .92 respectively. Therefore, Perceived Weight Stigmatization Scale turned out to be a reliable and valid instrument for measuring perception of weight stigma in adults with obesity.

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: Child obesity is one of the main health problems all across the world, which leads to mental and physical health problems. Various models are used in designing intervention to prevent child obesity, one of which is social-cognitive theory (SCT). The constructs of social-cognitive theory are commonly used for designing preventive interventions. However, there is no specific tool based on the constructs of social-cognitive theory to assess the factors associated with child obesity. Aim: The aim of this study was to investigate the validity and confirmatory factor analysis of a SCT-based questionnaire for assessing obesity preventing behaviors among 4-6 years old children. Method: A cross-sectional study was first conducted in 2016 on 240 preschool children aged 4-6 years in Behbahan city (a city in southwest Iran) to assess the obesity prevention behaviors among them using a SCT-based questionnaire. To investigate the validity and confirmatory factor analysis of the SCT-based questionnaire, content and face validity as well as forward-backward translation method were used. Reliability of the questionnaire was also measured by Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC). Construct validity was assured by confirmatory factor analysis. To measure the obesity prevention behaviors in 4-6 years old children, the construct of SCT, including environment, emotional coping, outcome expectations, goal setting and self-efficacy were used. Also, the obesity prevention behaviors used in the model included physical activity, consumption of fruit and vegetable, consumption of sugar-free drinks, and screen. Results: Results of this study confirmed the acceptable content and face validity of the SCT-based questionnaire. The results of confirmatory factor analysis also confirmed the factor loading of more than 0.3 for all variables; therefore, the SCT-based questionnaire had an acceptable validity and reliability. Conclusions: Since the SCT-based questionnaire had an acceptable validity and reliability, it can be used to assess the obesity prevention behaviors in 4-6 year old children, and also to design relevant educational interventions.
