The validity and reliability study on Turkish version of the Questionnaire of Changes in Experiencing and Behavior Yaşantı ve Davranışlarda Değişim Ölçeği Türkçe formunun geçerlik ve güvenirlik çalışması

The aim of this study is to adapt Questionnaire of Changes in Experiencing and Behavior (QCEB) developed by Zielke and Kopf-Mehnert (1978, 2001) to Turkish. The scale provides information about change, direction and strength after counseling. The original version of the questionnaire is in German; the scale is one factor and consists of 42 items. For the adaptation study, the original scale was firstly translated into Turkish. After linguistic equivalence study, item analysis, validity and reliability studies were carried out. Confirmatory factor analysis was conducted to test the validity of the structure and it was found that the compliance indices were acceptable (?²=2113;/sd=818; ?²/sd=2.5; CFI=.95; TLI=.94; RMSEA=0.08; SRMR=0.06). The results of this analysis show that the original factor structure of QCEB has been replicated and adequately validated in the sample of Turkish clients.  In addition, the analysis of the items revealed that total correlations of the items were significant. In the context of reliability studies of the scale, Cronbach ? and test-retest values were calculated. Based on this, the scale had Cronbach ? value of .96 and a test-retest value of .72. As a result, Questionnaire of Changes in Experiencing and Behavior shows that there is a valid and reliable scale that can be used to measure the change after counseling or psychotherapy in Turkey.  Extended English summary is in the end of  Full Text  PDF (TURKISH)  file .
