Abstract

Research on eating disorders (EDs) and body image disturbances has focused mostly on females from Western countries, and little is known about EDs in male populations in China, which is partially due to the lack of validated assessment measures. The current work aims to translate the Muscularity-Oriented Eating Test (MOET), Drive for Muscularity Scale (DMS) and Muscle Dysmorphic Disorder Inventory (MDDI) into Chinese and examine their psychometric properties. The factor structures, reliability and validity of the translated scales were examined with two samples: male university students (n = 295, Mage = 18.92 years) and general adult men (n = 406, Mage = 28.53 years). With confirmatory factor analyses, the original factor structures are replicated for the MOET, DMS and MDDI. The results also support the adequate internal consistency for both samples. Strong evidence of convergent and incremental validity for the three measures is also found in both samples. Overall, the three measures prove to be good instruments for use among Chinese male university students and general adult men.

Highlights

Eating disorders (EDs) are severe mental illnesses characterized by disturbances in eating behaviors and body image [1]
The results showed that the understandability of the Muscularity-Oriented Eating Test (MOET) ranged from 4.03 to 4.77, the understandability of the Muscle Dysmorphic Disorder Inventory (MDDI) ranged from 3.50 to 4.53, and the understandability of the Drive for Muscularity Scale (DMS) ranged from 4.20 to 4.67
We evaluated the concurrent validity of the MOET, DMS and MDDI by exploring the correlations between the scores of the three scales being validated and the theoretically correlated measures

Summary

Introduction

Eating disorders (EDs) are severe mental illnesses characterized by disturbances in eating behaviors and body image [1]. According to the previous literature [3,5,6], EDs and body image disturbances among women are typically thinnessoriented (i.e., drive for thinness), while EDs and body image disturbances among men are typically muscularity-oriented (i.e., drive for muscularity). The majority of the existing measures that are widely used for assessing ED symptomatology and body image disturbances are thinness-focused, such as the Eating Attitude. The measures are not sensitive enough to capture the core features of disordered eating or body image disturbances among men [5]
