Development of the Disordered Eating Scale for Adolescents Aged 14-18

Öz

This study aimed to develop a scale for evaluating disordered eating attitudes and behaviors among adolescents aged 14 to 18. The scale’s factor structure was examined with a total of 1379 participants, revealing 14 items and three sub-dimensions that accounted for 58.46% of the total variance. The scale demonstrated good internal consistency (Cronbach’s alpha = .86) and test-retest reliability (r = .90). Regarding criterion validity, the correlation between the Disordered Eating Scale (DES) and the Eating Disorder Examination Questionnaire (EDE-Q) was found to be .86. Receiver operating characteristic (ROC) analysis results indicated a sensitivity of .930 and a specificity of .91 for the ≥31 cut-off point. Confirmatory factor analysis (CFA) was conducted, and the model fit indexes for both applications were as follows: x2 = 287.43, df = 73, x2/df = 3.94, RMSEA = 0.079, CFI = 0.938, TLI = 0.922, and SRMR = 0.045. These findings supported the three-dimensional model, suggesting that disordered eating can be measured through restriction, weight anxiety, and extraction-control behaviors dimensions with a total of 14 items. The DES is deemed suitable for screening and evaluating negative eating behaviors and potential psychopathology in adolescents, including those with and without clinical eating disorder symptoms.

14-18 Yaş Arası Ergenler için Bozulmuş Yeme Ölçeği’nin Geliştirilmesi

Öz

Çalışmanın amacı, 14-18 yaş arası ergenler için bozulmuş yeme ile ilgili davranış ve tutumlarını değerlendiren bir ölçek geliştirmektir. “Bozulmuş Yeme Ölçeği” (BYÖ) adı verilen bu ölçeğin faktör yapısı toplam 1379 katılımcının katılımıyla ortaya çıkarılmıştır. Faktör analizi sonuçlarına göre ölçek 14 maddeden oluşmakta ve ölçeğin üç alt boyutu bulunmaktadır. Bu üç alt boyut toplam varyansın %58.46’sını açıklamaktadır. Ölçeğin iç tutarlılık değeri .86 iken test-tekrar test korelasyonu .90 olarak bulunmuştur. Ölçüt geçerlik için BYÖ ile Yeme Bozukluğu İnceleme Ölçeği (YBİÖ) arasındaki korelasyon .86’dır. İşlem karakteristik analizi sonuçlarına göre ≥31 kesme noktası için duyarlılık .930 ve özgüllük .911’dir. Ortaya çıkan yapıyı doğrulamak için doğrulayıcı faktör analizi uygulanmıştır. Her iki uygulama için de uyum indeksleri x2 = 287.43, df = 73, x2/df = 3.94, RMSEA = 0.079, CFI = 0.938, TLI = 0.922 ve SRMR = 0.045’tir. Ortaya çıkan yapı, bozulmuş yemenin kısıtlama, kilo kaygısı ve çıkarma-kontrol davranışları alt boyutlarında ve toplamda 14 madde ile ölçülebileceğini göstermektedir. BYÖ’nün yeme bozukluğu tanısı olan ve olmayan ergenlerde, olası psikopatolojiye ilişkin olumsuz tutum ve davranışları taramak ve değerlendirmek için geçerli ve güvenilir bir ölçek olarak kullanılabileceği bulunmuştur.
