Background: Human immunodeficiency virus (HIV/AIDS) is the factor causing AIDS. The virus is categorized into retroviruses that attack and destroy the immune system of the body and cause lethal infections. Objectives: The present study aimed to investigate the effectiveness of mindfulness-based cognitive therapy in the improvement of sleep quality and perceived social support of the patients with HIV/AIDS. Methods: The present study is randomized controlled trial research. The study population included individuals with HIV-AIDS from Ahvaz county's center of behavioral disease counseling. The study sample volume consisted of two groups, named mindfulnessbased cognitive therapy and control groups, each one contained 15 individuals who were selected randomly. The experimental intervention was undertaken during eight 1.5-hour sessions that were held once a week. To gather the data, the sleep quality scale, perceived social support questionnaire, SCL-90-R scale, and demographic factors questionnaire were used. Multivariate covariance analysis and SPSS-22 Software were utilized for analyzing the data. Results: In terms of gender, the experimental group consisted of 8 (53.3) women and 7 (46.7) men. In the control group, 4 (26.7) were women and 11 (73.3) were men. The mean (standard deviation) age of the participants in the experimental group was 35.7 (7.42) and the mean (standard deviation) of the age of the control group was 37.8 (9.1). The results showed that mindfulness-based cognitive therapy had a significant effect on sleep quality (F = 27.98, P < 0.001) and perceived social support (F = 36.20, P < 0.001) in patients with HIV/AIDS. Conclusions: It can be concluded that mindfulness-based cognitive therapy is effective in improving the sleep quality and perceived social support of patients with HIV/AIDS. Based on the results of this study, it seems that by teaching mindfulness-based cognitive therapy, patients' sleep quality and perceived social support can be reduced.

Background and Objective: Due to the role of recognition in eating disorders, the identification of core beliefs and cognitive schemas becomes debatable. This study aimed to determine the effectiveness of schema therapy in psychological distress, body image, and eating disorder beliefs in anorexic patients. Materials and Methods: This was an applied quasi-experimental study with a pretest and posttest design and control group. The statistical population of the study included patients with an eating disorder, attending the psychological, clinical psychiatric, and obesity treatment centers in Ahvaz, Iran, within the age range of 16-23 years in 2019. The subjects were selected using the purposive sampling method. In this study, the pretest (i.e., filling out the Eating Disorder Beliefs Questionnaire [EDBQ]) was performed before the schema therapy intervention. Then, the intervention was conducted on the experimental group; however, no intervention was carried out for the control group. After the termination of the treatment sessions (12 sessions of 45 min), the posttest was performed. Finally, 3 months following the termination of the treatment, the follow-up test was conducted. The data were obtained using the EDBQ, Psychological Distress Questionnaire, and Body Image Concern Inventory. The data were analyzed using multivariate analysis of covariance and SPSS software (version 22). Results: The results of the present study showed that schema therapy led to a decrease in psychological distress (F=157.36, P<0.0001, Eta=0.89), body image concern (F=8.03, P<0.001, Eta=0.29), and eating disorder beliefs (F=13.85, P<0.0001, Eta=0.91). Conclusion: It can be concluded that schema therapy reduces psychological distress, body image concerns, and eating disorder beliefs

Background and Aims: Given the success of group psychotherapy as well as drug therapies to improve drug-dependent patients, it is increasingly necessary to compare different interventions to select the most effective way to reduce the problems of methadone maintenance therapists. This study aimed to compare the effectiveness of existential group therapy with cognitive-behavioral group therapy on increasing the life satisfaction of addicted people under methadone maintenance therapy. Materials and Methods: This semi-experimental study was conducted based on the pretest-posttest method with a control group. The study population included addicted males who underwent methadone maintenance treatment at Qazvin Addiction Treatment and Injury Clinics in 2019, Qazvin, Iran. The participants (n=90) were randomly selected and divided into experimental (existential and cognitive-behavioral therapy) and control groups. Subsequently, the experimental groups participated in 10 sessions of 120-min per week. The data were analyzed in SPSS software (version 22) through a repeated-measures ANOVA. Results: The results showed the improvement of life satisfaction in the existential and cognitive-behavioral therapy groups (P<0.001); however, the control group showed no significant difference in pretest, posttest, and follow-up. Furthermore, the results indicated no significant difference between cognitive-behavioral and existential therapy groups in terms of life satisfaction (P>0.05). Conclusion: It can be concluded that both cognitive-behavioral and existential therapies are effective in increasing the life satisfaction of addicted patients under methadone maintenance therapy; however, no significant difference was observed between the two experimental groups regarding the increasing level of satisfaction.
