Purpose and Background: Eating disorders and obsessive-compulsive disorder co-occur on many occasions. Impulsivity is one of the prevalent features between the mentioned disorders. The purpose of this study is to compare the feature of impulsivity and its components in eating disorders, obsessive-compulsive disorder and the normal individuals. Methods and Materials: This study carried on patients suffering from eating disorders and obsessive compulsive disorder receiving treatment at Bozorgmehr clinic in Tabriz in 1389-1390, using a convenience sampling. A normal group matched with patients’ groups and Barratt impulsiveness scale was used to collect data. Findings: Data was analyzed using Multivariate Analysis of Variance (MANOVA). The results show that the clinical groups have the higher rates of impulsivity compared to the normal group  but there are no meaningful differences between the clinical groups. Regarding the components, the study shows that the attention impulsivity and non-planning impulsivity have significant differences between eating disorders and obsessive compulsive disorder with normal group, but there are no differences between two clinical groups. Regarding motor impulsiveness, there are no differences between the groups. Conclusions: high impulsivity and its components were noticed among the patients and this may justify the patients’ problems of behavioral inhibition and delay needs.

Aim and Background: The aim of the present study was to determine the effectiveness of transactional analysis based on motivational interviewing on patients with eating disorders. Methods and Materials: This quasi-experimental study was performed using a multiple baseline single case design. The study subjects consisted of 2 female clients of the psychological counseling unit of Imen Teb Zagros Center in Shiraz, Iran, in 2013. The participants were selected by purposive sampling method and underwent transactional analysis based on motivational interviewing. The subjects completed the Ahwaz Eating Disorder, Food Habits, Body Attitudes, Personality States, Interpersonal Relationships, and Self-esteem Questionnaires during pre-treatment (baseline) and at the third, eighth, fourteenth, nineteenth, and twenty-third sessions, and one-month follow-up. Moreover, their body mass index (BMI) was measured during the course of the treatment. Recovery percentage and the effect size were used for data analysis. For data analysis, percentage improvement and effect size index were used. Findings: The results showed that motivational interview-based transactional analysis was effective in curing patients with eating disorders and was been able to cause lasting and significant changes in all targets. At the end of the treatment and follow-up period, both participants demonstrated overall improvement in eating disorder (73%), eating habits (74%), body image (60%), interpersonal relationships (62%), self-esteem (54%), and personality states (76%). Conclusions: Transactional analysis based on motivational interviewing can be an effective treatment for patients with anorexia nervosa and bulimia nervosa.
