Objective: The Dysmorphic Concern Questionnaire (DCQ) is a widely used screening instrument assessing dysmorphic concerns ranging from a mild to an excessive level. In Iran, there is no brief and valid questionnaire for the assessment of body dysmorphic disorder.
Methods: To investigate the psychometric properties of this scale, 210 university students (103 males and 107 females) were selected by convenience sampling method. The study participants were requested to complete the DCQ, scales of external shame, self-compassion, negative affect, and perfectionism. LISREL and SPSS were used for analyzing the obtained data. Confirmatory Factor Analysis (CFA), correlation coefficient, and Cronbach's alpha coefficient were calculated, as well.
Results: The one-factor structure of DCQ was supported by the results of CFA in an Iranian sample (X2/df=2/12, RMSEA=0.07, NFI=0.94, CFI=0.97). Dysmorphic concern was positively and significantly correlated with external shame scale (0.38), perfectionism (0.22), and negative affect (0.22); however, they were negatively and significantly correlated with self-compassion (0.16). Cronbach's alpha coefficient was obtained equal to 0.78 in this respect.
Conclusion: DCQ demonstrated acceptable psychometric properties in university student populations. This scale has appropriate psychometric properties for research and clinical practice.

● Persian version of DCQ can be used as a useful tool to measure dysmorphic concerns in Iranian population.
● The internal consistency of the items in the Persian version of DCQ had acceptable Cronbach's alpha coefficient value (α=0.78).
● Dysmorphic concern was positively and significantly correlated with external shame scale, perfectionism, and negative affect.
● Dysmorphic concern negatively and significantly correlated with self-compassion.
Dysmorphic concerns are defined as excessive preoccupations with a slight or perceived defect in physical appearance. Many studies have suggested that a higher rate of negative affect is associated with body image dissatisfaction. Some instruments have been used to screen body dysmorphic concern including the Dysmorphic Concern Questionnaire (DCQ). It is a self-report scale with 7 items based on a 4-point scale measuring concerns about physical appearance. The present study aimed at examining the psychometric properties of the DCQ among Iranian samples. To investigate the psychometric properties of this scale, 210 university students were selected by a convenience sampling method. This questionnaire had high internal consistency and had good divergence and convergence validity. The results suggested acceptable psychometric properties of this tool in university student population in Iran. This scale has appropriate psychometric properties to be used for research and clinical practice.
