Adaptation of the Appearance Anxiety Inventory to Turkish and its psychometric properties in emerging adults: A comprehensive assessment with item response theory and network analysis
Abstract
The aim of the current study is to adapt the Appearance Anxiety Inventory (AAI), which is used to measure appearance anxiety, into Turkish. For this purpose, the psychometric properties of the AAI in Turkish culture were examined in a sample of emerging adults (N = 520). Confirmatory factor analysis supported the single-factor structure of the AAI, and the AAI showed measurement invariance across gender. Item response theory analysis revealed that the scale items had sufficient discrimination parameters for levels of appearance anxiety; differential item functioning analysis revealed that the scale items did not show differential item functioning according to gender. Network analysis determined that the items with the highest centrality were those regarding the individual hiding or changing his or her appearance. The scale yielded a McDonald's ω value of .91, a Cronbach's α value of .90, and an intraclass correlation coefficient of .88. The findings of the study indicate that the AAI has sound psychometric properties that can be used in the assessment of appearance anxiety in emerging adults in the Turkish population.
