Turkish Adaptation, Validity, and Reliability Study of the Children and Adolescent Behavior Inventory Family Questionnaire

Introduction: This study aimed to conduct the Turkish adaptation, validity, and reliability analyses of the Children and Adolescent Behavior Inventory (CABI) Family Questionnaire. Method: A total of 1015 parents of children and adolescents aged 6-14 years, with 762 from the community sample and 253 from the clinical sample, participated in the study. After the language adaptation of the scale was completed by experts, its construct validity was determined using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and discriminant validity. The reliability was assessed with Cronbach's alpha internal consistency coefficients, and the test-retest reliability of the scale was tested on 100 participants. Results: The results of the EFA showed that the scale had 10 factors. The items associated with the 10th factor, which was different from the original scale, aligned with the subscales of the Sluggish Cognitive Tempo. The results of the CFA indicated that the factor load values were statistically significant, and the fit index values were at moderate, good, and excellent levels. A comparison of the subscale scores of the clinical and population sample groups showed that the scale had a distinctive feature. The Cronbach's alpha value of the total scale score was calculated to be 0.94. No statistically significant difference was found between the mean test-retest scores obtained on the subscales. The test-retest correlation coefficient was found to be within the range of r=0.605-0.853 for the subscales (p<0.01). Conclusion: This study proved that the CABI Family Questionnaire was a valid and reliable scale and could be administered to the parents of Turkish children and adolescents aged between six and 14 years in population and clinical samples.
