Beden Algısı Bozukluğu ve İşlevsellik Ölçeği: Geliştirme, Geçerlik ve Güvenirlik

Öz

Bu çalışma, beden algısı bozukluklarını ve bunların günlük işlevsellik üzerindeki etkilerini kapsamlı bir şekilde değerlendirmek amacıyla Beden Algısı Bozukluğu ve İşlevsellik Ölçeği’ni (BİBİÖ) geliştirmeyi hedeflemiştir. Ölçek geliştirme süreci, alanyazın ve uzman görüşleri temelinde oluşturulan 198 maddelik bir havuz ile başlamış, pilot uygulama ve açımlayıcı faktör analizi sonucunda 21 maddeye indirgenmiştir. Nihai form üç boyuttan oluşmaktadır: bilişsel-duygusal belirtiler, görünümle ilişkili davranışlar ve işlevsel kaçınma. Geniş bir yetişkin örnekleminde (N = 723) yapılan doğrulayıcı faktör analizi üç faktörlü yapıyı desteklemiştir. Ölçek yüksek iç tutarlılık (α = 0,94) ve test-tekrar test güvenirliği (r = 0,82) göstermiştir. BİBİÖ’nün, BIDQ-S, SAAS ve MDDI ile anlamlı korelasyonları yakınsak geçerliği doğrulamıştır. Ayırt edici geçerlik ise yüksek ve düşük semptom grupları arasındaki anlamlı farklılıklarla desteklenmiştir. Genel olarak, BİBİÖ beden algısı bozukluklarını ve bunların işlevsel sonuçlarını genel popülasyonda değerlendirmek için geçerli ve güvenilir bir araçtır.

BODY IMAGE DYSFUNCTION AND FUNCTIONALITY SCALE: DEVELOPMENT, VALIDITY, AND RELIABILITY

Öz

This study aimed to develop the Body Image Dysfunction and Functionality Scale (BIDFS) to comprehensively assess body image disturbances and their impact on daily functioning. The scale development process began with a 198-item pool based on literature and expert input, which was refined to 21 items through pilot testing and exploratory factor analysis. The final version includes three dimensions: cognitive-emotional symptoms, appearance-related behaviors, and functional avoidance. Confirmatory factor analysis in a large adult sample (N = 723) supported the three-factor structure. The scale demonstrated high internal consistency (α = 0.94) and test-retest reliability (r = 0.82). BIDFS showed significant correlations with BIDQ-S, SAAS, and MDDI, confirming convergent validity. Discriminant validity was supported by significant differences between high and low symptom groups. Overall, BIDFS is a valid and reliable instrument for evaluating body image dysfunction and its functional consequences in the general population.
