The Turkish Adaptation of the Friendship Qualities Scale: A Validity and Reliability Study
Özet
In this study, the authors have aimed to adapt the Friendship Qualities Scale (FQS) in order to determine friendship relation levels among adolescents. A total of 603 high school students from Ankara Turkey, were selected using convenient sampling to participate in this study. During the course of this study, the FQS was first translated into Turkish and then its psychometric properties were examined. The construct validity of the FQS was tested using a confirmatory factor analysis (CFA). Before performing the CFA, the assumption of missing values, outliers, normality, and collineriaty were checked. According to the results, the 22-item FQS consisting of 5 dimensions had acceptable goodness of fit indexes (S-Bx(2)/df = 669.12/199, p = .00, RMSEA = .063, CFI = .97, GFI = .88, NNFI = .96). The Cronbach alpha coefficients of the subscales ranged between .66 and .86. The internal consistency for the entire scale was alpha = .85. In conclusion, an instrument consisting of 22 items and 5 subscales was prepared for future researchers.
