Turkish validity and reliability of the Treatment Assessment Scale Parent Form

Abstract

Purpose: The aim of this study was to adapt the Treatment Assessment Scale Parent Form into Turkish and evaluate its validity and reliability. Materials and Methods: The sample of the study consisted of parents whom children were treated in day treatment. The data of 133 parents who completed at discharge the. For validity, exploratory and confirmatory factor analyses were performed. Reliability was evaluated by Cronbach's alpha internal consistency coefficient and item-total score correlation coefficients. Results: After the confirmatory factor analyses applied to the original scale, it was observed that the fit indices of the scale were not at the desired level. After the Kaiser Meyer Olkin index was 0.84 and the Chi-square score in the Bartlett Test was determined as 831.68 (p<0.001), exploratory factor analysis was applied. Modification of 3., 8. and 11. items from the Treatment Course subscale to the Treatment Success subscale has been proposed. The explanatory rate of the total variance, which supports the validity of the two reconstructed factors, was found to be over 40%, and the fit indices of the scale were found to be more acceptable than the original scale. In the internal consistency analyses Cronbach's alpha coefficient was 0.88 for the entire scale, 0.88 for the Treatment Success subscale and 0.81 for the Treatment Course subscale. Conclusion: These results support that the scale adapted into Turkish is a valid and reliable assessment instrument.
