Journal Title: Journal of Human Sciences - Year 2018, Vol 15, Issue 3
Abstract
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.ÖzetBu çalışmanın amacı, Zielke ve Kopf-Mehnert (1978, 2001) tarafından geliştirilen Yaşantı ve Davranışlarda Değişim Ölçeğini (YADA) Türkçeye uyarlamaktır. Ölçek psikolojik danışma sonrasındaki değişimin, yönü ve gücü hakkında bilgi sunmaktadır. Özgün formu Almanca olan ölçek, tek faktörlü ve 42 maddeden oluşmaktadır. Uyarlama çalışması için öncelikle özgün ölçeğin Türkçeye çevirisi yapılmıştır. Dilsel eşdeğerlilik çalışmasının ardından madde analizi, geçerlik ve güvenirlik çalışmaları gerçekleştirilmiştir. Yapı geçerliğini test etmek için doğrulayıcı faktör analizi yapılmış ve uyum indekslerinin kabul edilebilir düzeyde olduğu bulunmuştur (χ²=2113;/sd=818; χ²/sd=2.5; CFI=.95; TLI=.94; RMSEA=0.08; SRMR=0.06). Bu analiz sonuçları YADA'nın orijinal faktör yapısının Türk danışanlardan oluşan örneklemde yinelendiğini ve yeterli düzeyde geçerliliğinin olduğunu göstermektedir. Ayrıca yapılan madde analizi ölçekteki maddelerin, madde toplam korelasyonlarının anlamlı olduğunu ortaya koymaktadır. Ölçeğin güvenirlik çalışmaları bağlamında Cronbach α ve test-tekrar test değerleri hesaplanmıştır. Buna göre ölçeğin Cronbach α değeri .96 ve test-tekrar test değeri .72 olarak tespit edilmiştir. Sonuç olarak Yaşantı ve Davranışlarda Değişim Ölçeği'nin Türkiye'de psikolojik danışma veya psikoterapi sonrasında danışanlardaki değişimin ölçülmesinde kullanılabilecek geçerli ve güvenilir bir ölçek olduğunu göstermektedir.
