ABSTRACT
In recent years, there has been a growing interest in the interrelationships among obsessive- compulsive disorder, impulsivity, and serotonin and previous studies produced mixed results. This study aimed at investigating the comparison of impulsivity between responsive and non-responsive obsessivecompulsive patients to selective serotonin reuptake inhibitors [SSRIs]. In an ex post facto design, using Sadock and Sadock's [2007] definition, and through convenience sampling, 27 Obsessive-Compulsive patients were divided into two groups [responsive and nonresponsive to SSRI] and were examined through 11th Barratt Impulsivity Scale, Yale-Brown Obsessive-Compulsive Scale [symptom checklist], and Structured Clinical Interview for DSM-IV. The mean scores of impulsivity and its components in responsive patients were higher in comparison with non responsive ones. Centroids of responsive and non responsive groups were significantly different regarding impulsivity, attentional, motor, and nonplanning impulsiveness [p< 0.009]. Among the four variables, there were significant differences only in impulsivity [p<0.01], attention [p< 0.01] and impulsiveness between responsive and non responsive groups [p <0.05]. The findings of this research shows that there is a significant difference in impulsivity level between responsive and non-responsive obsessive-compulsive patients to SSRIs, and the mean score of impulsivity in nonresponsive patients is higher. However, attending to some paradoxes in the literature, more researches are needed to provide a comprehensive theoretical explanation for the interrelationships among impulsivity, OCD, and responsivity to SSRIs
ABSTRACT
Todays, The etiology of binge eating has not been definitively determined. Treatment must address the somatic, the behavioral, and the psychological problems. The aim of this study was to determine the effectiveness of cognitive behavior group therapy on reducing symptoms of binge eating disorder in woman of Ahvaz overeating anonymous. Subjects were consisted of 30 patients with binge eating disorder that were selected from overeating anonymous. Sampling was convenience then patients who were diagnosed with binge scale and clinical interview, were randomly assigned to experimental and control groups. The experimental group received 6 weekly sessions of cognitive behavior group therapy that the control group did not received. It was hypothesized that cognitive behavior group therapy decrease the symptoms of binge eating disorder of the experimental group as compared with the control group. The binge scale was administered to both groups before and after treatment. SPSS 16 software was used for data analysis The results of covariance analysis showed that cognitive behavior group therapy significantly reduced the symptoms of binge eating [F=107.16, p<0.001] in the experimental group as compared with the control group. This study showed that cognitive behavior therapy is effective on reducing symptoms of binge eating, and this method can be one of the treatment choices for this disorder considered by the therapist
