Reliability and Validity of the Turkish Version of Children's Somatization Inventory

PURPOSE The purpose of this study was to examine the psychometric properties of the Childrens Somatization Inventory (CSI) in Turkish schoolchildren and adolescents. METHODS The CSI was translated using translation and back-translation. The participants were 813 schoolchildren, adolescents and their parents (n=453). Content and construct validity were assessed to test the validity of the CSI-24. Internal consistency reliability, interrater reliability (child-parent agreement) and test-retest reliability were assessed to test the reliability of the CSI-24. RESULTS Psychometric analyses of the Turkish version of the CSI-24 indicate high reliability and good content and construct validity. CONCLUSION The Turkish version of the CSI-24 is a useful instrument for measuring self-reported somatic complaints in Turkish schoolchildren and adolescents between the ages of 9 and 15.

Reliability and Validity of the Turkish Version of the Situational Self-Efficacy Scale for Fruit and Vegetable Consumption in Adolescents

Purpose. The purpose of this research was to examine the psychometric properties of the Turkish version of the situational self-efficacy scale for vegetable and fruit consumption in adolescents. Design. This was a methodological study. Setting. The study was conducted in four public secondary schools in Istanbul, Turkey. Subjects. Subjects were 1586 adolescents. Measures. Content and construct validity were assessed to test the validity of the scale. The reliability was assessed in terms of internal consistency and test-retest reliability. Analysis. For confirmatory factor analysis, χ2 statistics plus other fit indices were used, including the goodness-of-fit index, the adjusted goodness-of-fit index, the nonnormed fit index, the comparative fit index, the standardized root mean residual, and the root mean square error of approximation. Pearsons correlation was used for test-retest reliability and item total correlation. The internal consistency was assessed by using Cronbach α. Results. Confirmatory factor analysis strongly supported the three-component structure representing positive social situations (α = .81), negative effect situations (α = .93), and difficult situations (α = .78). Psychometric analyses of the Turkish version of the situational self-efficacy scale indicate high reliability and good content and construct validity. Conclusion. Researchers and health professionals will find it useful to employ the Turkish situational self-efficacy scale in evaluating situational self-efficacy for fruit and vegetable consumption in Turkish adolescents.
