2022 Uluslararası Uzlaşı Sonrasında Ortoreksiya Nervoza Ölçümündeki Gelişmeler: Psikometrik Kanıtlara Dayalı Sistematik Bir Derleme

Öz

Ortoreksiya Nervoza (ON), sağlıklı beslenmeye yönelik aşırı zihinsel uğraş, katı diyet kontrolü, duygusal sıkıntı ve işlevsel bozulma ile karakterizedir. Araştırma alanındaki ilerleme, tutarsız tanı ölçütleri ve heterojen ölçüm araçları nedeniyle sınırlı kalmıştır. 2022 uluslararası uzlaşı raporu, ON için temel tanı alanlarını tanımlayarak çağdaş ölçek geliştirme çalışmalarına bir çerçeve sunmuştur. Bu tarihten sonra yeni ON ölçüm araçları geliştirilmiş olsa da, bunların psikometrik kalitesi ve uzlaşı temelli ölçütlerle kavramsal uyumu henüz bütüncül olarak sentezlenmemiştir. PRISMA 2020 rehberine uygun bir sistematik derleme yürütülmüştür. PubMed, Scopus ve Web of Science Core Collection veri tabanlarında, Ocak 2023 ile Ocak 2026 tarihleri arasında yayımlanmış ve ON ölçüm araçlarının geliştirilmesini raporlayan çalışmalar taranmıştır. Dahil edilme kriterlerini karşılayan beş çalışma analize alınmıştır. Örneklem büyüklükleri 418 ile 978 katılımcı arasında değişmektedir. Tüm araçlar faktör analizine dayalı doğrulama raporlamış ve kabul edilebilirden mükemmele değişen iç tutarlılık düzeyleri bildirmiştir (α/ω = 0,77–0,94). İki araç zamansal kararlılığı değerlendirmiş, iki araç ise kesme puanları önermiştir. Alan eşleştirme sonuçları, sağlıklı beslenmeye yönelik zihinsel uğraşın tüm araçlarda tutarlı biçimde değerlendirildiğini göstermiştir. Uzlaşı sonrası geliştirilen ON ölçüm araçları, psikometrik açıdan ilerleme göstermektedir. Ancak kavramsal olarak çeşitlilik sürmektedir.

Advancements in the Measurement of Orthorexia Nervosa After the 2022 International Consensus: A Systematic Review of Psychometric Evidence

Öz

Orthorexia Nervosa (ON) involves excessive preoccupation with healthy eating, rigid dietary control, emotional distress, and functional impairment. Research progress has been limited by inconsistent diagnostic criteria and heterogeneous ON assessment instruments. The 2022 international consensus report defined core diagnostic domains for ON, providing a framework for contemporary scale development. Novel ON assessment instruments have since emerged, yet their psychometric quality and conceptual alignment with consensus-based criteria have not yet been synthesized. A PRISMA 2020-guided systematic review was conducted. PubMed, Scopus, and Web of Science Core Collection were searched for studies published between January 2023 and January 2026 reporting the development of ON assessment instruments. Five eligible studies were included. Sample sizes ranged from 418 to 978 participants. Two instruments assessed temporal stability, and two proposed preliminary cut-off scores. All instruments reported factor-analytic validation and acceptable-to-excellent internal consistency (α/ω ranging from .77 to .94). Domain mapping demonstrated uniform assessment of preoccupation with healthy eating. Post-consensus ON assessment instruments demonstrate advancing psychometric sophistication but remain conceptually diverse.
