The purpose of this study is to develop the "Bicycle Handicap Scale (BHS)" and to test the validity of the scale to demonstrate the obstacles bicyclists encounter. 292 bicycle riders cycling in Eskisehir and Ankara for various purposes for transportation or recr[1]eational purposes in their daily life were participated voluntarily. Explanatory and confirmatory factor analysis was performed in order to ensure the validity of the BEÖ structure. As a result of the exploratory factor analysis, a 5-dimensional structure was obtained on the scale. In the confirmatory factor analysis, five factorial structure was tested and it was determined that the obtained model was in accordance with the compliance criteria. According to this, BEÖ consists of 30 items consisting of 8 items in individual dimension, 5 items in law and regulation, 6 items in socio-cultural dimension, 7 items in physical and economic dimension and 4 items in infrastructure dimension. The internal consistency coefficient of the BEÖ was .92 for the scale, and between .89 and .73 for the subscales of the scale. As a result; It has been found that BEÖ is a useful measuring tool, developed to measure the attitudes of cyclists towards the obstacles encountered while riding a bicycle as a result of the validity and reliability studies conducted.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetBu çalışmanın amacı, bisiklet kullanıcılarının karşılaştıkları engelleri ortaya koyabilmek amacıyla “Bisiklet Engelleri Ölçeği’ni (BEÖ)” geliştirmek ve ölçeğin geçerlik güvenirlik çalışmasını yapmaktır.

Perceived Autonomy Support

The purpose of this study was to examine the validity and reliability of Perceived Autonomy Support Scale for Exercise Settings (PASSES; Hagger et al., 2007) from teacher and from peers in Turkish context. It was conducted with volunteer university students. 230 university students completed PASSES from teacher, and 142 university students completed PASSES from peers. Each scale has 12 items with a unidimension structure. The items were rated on a 7-point Likert type scale from totally disagree (1) to totally agree (7). Each scale was analyzed by using confirmatory factor analysis (CFA) to determine validity and by using Cronbach alpha value to determine reliability. The validity analyses for each scale showed good fit indexes in Turkish context. The reliability analyses also showed high reliability scores for each scale. Results were consistent with previous studies. It was suggested that PASSES from teacher and from peers can be used in Turkish context. ÖzetBu araştırmanın amacı “Egzersizde Algılanan Özerklik Desteği Ölçeğinin” (Perceived Autonomy Support Scale for Exercise Settings; Hagger ve diğ., 2007) hem öğretmen hem de arkadaşlar versiyonunu Türkçeye uyarlamak ve her iki ölçeğin geçerlik ve güvenirliğini incelemektir. Bu amaçla Türkçeye çevrilen ölçekler bir grup üniversite öğrencisine uygulanmıştır (öğretmen versiyonu için n = 230; arkadaşlar versiyonu için n = 142). Tek boyutlu olan ölçekler 12 ifadeden oluşmaktadır ve ifadeler tamamen katılmıyorum (1)’dan tamamen katılıyorum (7)’a doğru sıralanan yedili Likert üzerinden değerlendirilmektedir. Ölçeğin yapı geçerliğini belirlemek için doğrulayıcı faktör analizi uygulanmış, iç güvenirliğini tespit etmek için de Cronbach alfa kat sayısı hesaplanmıştır. Her iki ölçeğin yapı geçerliği bulguları iyi uyum indeksleri göstermiştir. Her iki ölçeğin iç güvenirlik kat sayıları da oldukça yüksek olarak hesaplanmıştır. Elde edilen bulgular alan yazında ilgili araştırmalarla benzerlik göstermektedir. Egzersizde Algılanan Özerklik Desteği Ölçeğinin hem öğretmen hem de arkadaşlar versiyonunun Türkçede ilgili araştırmalarda kullanılabileceği önerilmektedir.

AbstractThe present study developed a Brazilian adaptation of the BAS for young adolescents, testing its factor structure by the Confirmatory Factor Analysis (CFA), concurrent and criterion validity, and its internal consistency. Participants were 347 adolescents (171 male and 176 female, aged between 10 and 13 years old). Three psychologists experts in psychological evaluation and three teachers of Portuguese of elementary school also participated for the adaptation stage of the items in order to be properly understood by the sample age group. There were few changes from the version culturally adapted for the Brazilian adult population. Cronbach’s alpha coefficients were satisfactory for the general population and both sexes (.804; female =.851; male =.752). The one-factor model of the BAS was confirmed by the confirmatory factor analysis with good indicators for the measurements of adjustment to the model, χ2 = 77.9; GFI = 0.967; NFI = 0.940, CFI = 0.979; TLI = 0.968; RMSEA;.038). The convergent validity analyzes revealed significant correlations between BAS scores and BMI (r = –.230; p < .001) and between the first and body image satisfaction (r = .309; p < .001). The BAS version for Brazilian young adolescents had adequate levels of validity and reliability, keeping the one-dimensional structure which indicates its use in Brazilian adolescent’s samples.

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: 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.

Grit, as a positive psychological trait, could affect the stability of nursing workforce and nurses’ physical and mental health continuously. The Short Grit Scale (Grit-S) with fewer items than the original Grit Scale was widely used to measure individual trait-level grit. However, the psychological properties of Grit-S among Chinese nurses have not been verified. A self-designed sociodemographic questionnaire was used to investigate 709 Chinese nurses in the study, and Grit-S, Big Five Inventory-44, Brief Self-Control Scale, 10-item Connor-Davidson resilience scale, and Task Performance Scale were adopted to collect information of grit, personality, self-control, resilience, and work performance. The confirmatory factor analysis, Pearson correlation analysis, hierarchical regression analysis, and multi-group confirmatory factor analysis were conducted to verify the psychometric properties of the Grit-S. The results demonstrated that the Grit-S had sound validity and reliability among Chinese nurse samples and had good measurement invariance across nurses in general hospitals and psychiatric hospitals. The results of this study provide confidence in using the grit measurement among Chinese nurse in the future.
