Validity and Reliability Testing of a Quality of Life Measurement Instrument "Child Health and Illness Profile-CHIP-AE" For Adolescents Aged Between 12 and 17.

Objective: In this study, it was aimed to make a cultural adaptation of the Child Health and Illness Profile-Adolescents (CHIP-AE) measurement tool for adolescents, which was developed by Starfield in 1993, to analyze whether the Turkish version is reliable, valid and applicable. Material and Methods: The sample of the study consisted of adolescents aged between 12 and 17, receiving inpatient treatment in the Children's Health and Diseases Clinic in the Faculty of Medicine at Eskisehir Osmangazi University, and adolescents aged between 12 and 17, studying in a private school. The original version of CHIP-AE in English was first translated into Turkish, and then back translated. All stages of the cultural adaptation were performed by a specialized committee. Confirmatory Factor Analysis was conducted on LISREL to test the validity of the instrument. Results: For the purpose of this study, the Turkish version of the CHIP-AE (12-17 years) was administered to 252 adolescents receiving inpatient treatment [148 (58.7%) female; 104 (41.3%) male] and 223 healthy adolescents [109 (48.9%) female; 114 (51.1%) male]. The average age was 14.32±1.70 in the group of ill adolescents, and 14.57±1.51 in the group of healthy adolescents. With regard to reliability, Cronbach's was 0.852 in the group of ill adolescents, and 0.807 in the group of healthy adolescents. These values refer to perfect reliability. Confirmatory Factor Analysis (CFA) was conducted to test construct validity. Model fit results obtained in CFA were as follows: χ²=1622.07, df=1061, p-value=0.000 RMSEA=0.046 in the group of ill adolescents; and χ²=2082.33, df=1208, p-value=0.000 RMSEA=0.057 in the group of healthy adolescents. Thus, validity results comply with the standards. Conclusion: This study suggests that the version developed for Turkish adolescents has high validity for the groups of both healthy and ill Turkish adolescents. [ABSTRACT FROM AUTHOR]
