This study aimed to: (a) determine the inter-rater reliability of the proposed muscle dysmorphia criteria, (b) investigate if muscle dysmorphia (MD) represented a syndrome of frequently co-occurring symptoms, and (c) determine the level of correlation between the proposed MD criteria and the Muscle Appearance Satisfaction Scale. Men (N = 48) aged 18 years and older who were currently participating in resistance training were assessed using the Muscle Appearance Satisfaction Scale and a one-on-one interview. Two qualified psychologists assigned a diagnosis of MD to those participants who appeared to meet the proposed criteria for MD. Inter-rater reliability and the frequency of co-occurring symptoms in participants were assessed. The correlation between MD and the Muscle Appearance Satisfaction Scale was explored. The inter-rater reliability between the researchers was low (Cohen's kappa = .39; p ≤ .05). A Binomial test revealed that MD represented a syndrome of frequently co-occurring symptoms; there was ...
