Testing the psychometric properties of the Turkish culture version of the self-efficacy scale for pediatric chronic illness

The aim of the study was to evaluate the validity and reliability and to test the psychometric properties of the Turkish culture version of the Pediatric Rating of Chronic Illness Self-Efficacy Scale (PRCISE). The sample of this methodological study consisted of adolescents with chronic disease who were followed up in pediatric polyclinics. 220 adolescents aged 10–17 were included in the study. The study was conducted between April and November 2019 at a university hospital in Turkey. Data were collected using face-to-face interviews with the participants visited to the outpatient clinic in the hospital. Questionnaires (personal information form and Pediatric Rating of Chronic Illness Self-Efficacy Scale) were administered to the adolescents. Psychometric testing consisted of internal consistency reliability (item-total correlations and Cronbach alpha coefficient), test-retest reliability, and validity (exploratory factor analysis and confirmatory factor analysis). In the exploratory factor analysis, Barlett’s sphericity test was (χ2(105) =497.953; p = 0.000). The five-factor model with an eigenvalue value of more than 1 in the exploratory factor analysis obtained the best and acceptable fit indices in the confirmatory factor analysis. The factor structure was verified by the confirmatory factor analysis. In the confirmatory factor analysis, the model fit indices of this scale were obtained as follows: Goodness-of-Fit Index = 0.92, Comparative Fit Index = 0.87, and Root Mean Square Error of Approximation = 0.55. Cronbach alpha value indicating the internal consistency of the entire scale was .703. The PRCISE is a reliable and valid instrument for Turkish adolescents with chronic illness.
