The aim of this research is to compare the effectiveness of personal intelligence and body intelligence training on the symptoms of body dysmorphic disorder in cosmetic surgery applicants with mixed models.
Methods: This study is semi-experimental study which was conducted through pre-test, posttest and follow-up. Statistical samples of the present study consisted of 48 applicants who referred to Tabriz cosmetic surgery centers in 2016. Samples were randomly divided in to three groups of 16 (personal intelligence, body intelligence training groups and control groups). For collecting data, “Mayer’s Personal Intelligence”, “Anderson’s Body Intelligence”, and “Body Dysmorphic Metacognition Questionnaire (BDMÇQ)” Were used. The validity and reliability of the questionnaires were confirmed in the previous studies.  The data was analyzed with SPSS.22 statistical software.
Results: Results shows that the personal intelligence and the body intelligence training have significant effects on decreasing the body dysmorphic disorder in the cosmetic surgery applicants (F= 3.8; P<0.006). But difference effectiveness of these interventions is not significant to treat the body dysmorphic disorder in cosmetic surgery applicants (F=-2.87; P>0.05).
