Abstract
Objective: Deficits in motivation to change are common among individuals with eating disorders, yet there has been an absence of research on motivation in non-Western countries. The aim of this study was to develop mea-sures of motivation to change based on the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) and the Bulimia Nervosa Stages of Change Questionnaire (BNSOCQ) in a Turkish population. Methods: Forty-four women with anorexia nervosa and thirty-one women with bulimia nervosa participated in the study. In order to show the reliability of the ANSOCQ and BNSOCQ, Cronbach’s alpha values were evaluated. Pearson Correlation Coeffi-cient test was used to analyze correlations between the ANSOCQ/BNSOCQ and both the Eating Disorder Examination Questionnaire (EDEQ) and Beck Depression Inventory (BDI). The Student’s t-test for independent samples was used to compare mean total scores on the ANSOCQ and BNSOCQ across the current phase of illness groups. Results: The Turkish versions of the ANSOCQ and BNSOCQ demonstrated good internal consistency (Cronbach’s alpha=0.92 and 0.89, respectively). In terms of convergent validity, negative correlations were found between the ANSOCQ/BNSOCQ and each of the EDEQ subscales and (for the ANSOCQ alone) the BDI. Also, participants in the active phase of illness reported a significantly lower level of motivation compared to those in remission. Discus-sion: The study provides initial support for the reliability and validity of the ANSOCQ and BNSOCQ in a Turkish sample, which will enable greater cross-cultural research on motivation in eating disorders.

Key words: eating disorders, anorexia nervosa, bulimia nervosa, motivation, stages of change



Anoreksiya Nervoza Değişim Evreleri Ölçeği ve Bulimiya Nervoza Değişim Evreleri Ölçeği: Türk örnekleminde psikometrik özellikleri

Özet
Amaç: Yeme bozukluğu olgularında değişime yönelik motivasyon eksikliğine sık rastlanmakla birlikte, batılı olma-yan ülkelerde bu alandaki araştırmalar oldukça azdır. Bu doğrultuda çalışmamızın amacı, değişime yönelik motivas-yonu ölçen Anoreksiya Nervoza Değişim Evreleri Ölçeği (ANDEÖ) ve Bulimiya Nervoza Değişim Evreleri Ölçeğinin (BNDEÖ) Türkçeye uyarlamasının yapılmasıdır. Yöntem: Araştırmada 44 anoreksiya nervoza ve 31 bulimiya nervoza olgusu yer almıştır. ANDEÖ ve BNDE֒nün güvenilirlik düzeyleri Cronbach alfa iç tutarlılık katsayısı analizi ile ölçülmüştür. Ayrıca ANDEÖ/BNDEÖ ile Yeme Bozukluğunu Değerlendirme Ölçeği (YBDÖ) ve Beck Depresyon Ölçeği (BDÖ) arasındaki ilişkiler Pearson korelasyon katsayısı analizi ile incelenmiştir. Son olarak ANDEÖ/BNDEÖ toplam puanlarının hastalığın evrelerine göre farklılaşıp farklılaşmadığı bağımsız örneklemler t-testi ile analiz edil-miştir. Sonuçlar: ANDEÖ ve BNDE֒nün Cronbach alfa iç tutarlılık düzeyleri sırasıyla 0.92 ve 0.89 olarak bulun-muştur. Yakınsak geçerlilik bağlamında ANDEÖ/BNDEÖ ile YBDÖ ve BDÖ puanları arasında (sadece ANDEÖ ile) negatif korelasyonlar bulunmuştur. Ayrıca, hastalığın akut olduğu olguların, remisyonda olan olgulara göre motivas-yonları anlamlı olarak daha düşüktür. Tartışma: Araştırma bulguları ANDEÖ ve BNDE֒nün güvenilirlik ve geçerli-liğinin kabul edilebilir düzeyde olduğunu desteklemekte ve ölçeklerin Türk toplumunda kullanımının uygun olduğunu ortaya koymaktadır. Araştırma sonuçlarının yeme bozukluklarında motivasyonel durumun kültürler arası araştırıl-masına destek sağlayacağı düşünülmektedir.

Anahtar Kelimeler: yeme bozuklukları, anoreksiya nervosa, bulimiya nervosa, motivasyon, değişim evreleri
