The Effect of Positive Mindfulness Therapy, Mindfulness Based cognitive Therapy and Cognitive-Behavioral Therapy on Aggression and Mood States of Female Students with Depression

Aggression and low level of mood states are the problems which female students with depression suffer from them. Therefore, the aim of this study was to compare the effect of Positive Mindfulness Therapy (PMT), Mindfulness Based Cognitive Therapy (MBCT) and Cognitive Behavioral Therapy (CBT) on aggression and mood states in female students with depression.  The research method was semi-experimental with pretest-posttest and control group. Out of 300 female high school students in Nain City in 2017, 60 participants were selected using purposeful method based on entry and exit criteria and randomly assigned into four groups (control, PMT, MBCT and CBT). To measure the dependent variables, the Aggression Questionnaire (AQ) and Brunel Mood Scale (BRUMS) were used. The group of PMT, MBCT and CBT received 12 sessions of treatment and the control group did not receive any treatment. The data were analyzed with the use of analysis of covariance (ANCOVA). Based on the results of ANCOVA, all three treatments had a significant effect on decrease of aggression and increase of mood states (p<0.01). Also, the effect of PMT was more than MBCT and CBT on reducing aggression (p<0.01), but the effect of three types of treatment on mood states was similar (p>0.05). Considering the more powerful effect of PMT compared to other two treatments in decreasing aggression and with the equal effects of three types of treatment on mood states, the use of these treatments is suggested for girl students with depression.
