Assessment Scale for Body Dysmorphic Disorder (AS-BDD): psychometric properties
This study analyzed the psychometric properties of the second version of the Assessment Scale for Body Dysmorphic Disorder (AS-BDD). It is a scale of self-report, with 40 items, developed to evaluate 3 dimensions of Body Dysmorphic Disorder (BDD): (a) excessive concern with a minor or imagined flaw in his/her personal physical characteristics, (b) significant clinical suffering and functional damage in important areas of life, and (c) such concern is not better explained by another disorder. The construct analysis by judges indicated accordance in 35 items which were answered by 30 patients diagnosed with BDD and 400 university students. The validity of criterion measures indicated ability to discriminate the items among the individuals of both sampled groups. The exploratory factor analysis suggested a unidimensional structure of the scale which allows to measuring "excessive concern with a minor or imagined flaw in his/her personal physical characteristics and the functional damages in different areas of life". The withheld items have shown excellent internal consistency. Cut point definitions and the ability to discriminate other disorders should be further studied.
