Background and Aims: Generalized anxiety and depression are prevalent in patients with type 2 diabetes. Type 2 diabetes is one of the most common chronic diseases leading to many complications. This study aimed to compare the effectiveness of metacognitive therapy and behavioral activation on depression in the elderly with type 2 diabetes. Materials and Methods: This quasi-experimental study was conducted based on a pretest-posttest design using a follow-up and control group. The study population consisted of elderly with type 2 diabetes who referred to five endocrine and metabolism clinics in region 11 of Tehran, Iran, during 2017. A total of 45 males and females were selected by purposive sampling method based on the inclusion criteria. Then they were assigned randomly to one control and two case groups. The Beck Depression Inventory (Second Edition) was utilized to measure the depression scale. In total, eight 90-min group intervention sessions were held weekly. The data were analyzed in SPSS software (version 25) through analysis of covariance and repeated measures ANOVA. Results: The results showed that metacognitive therapy (F=15.07, P<0.001) and behavioral activation (F=7.09, P<0.008) were significantly effective on depression in the elderly with type 2 diabetes, and there was a significant difference between the experimental and control groups in this regard (P<0.001). Conclusions: This study was conducted to compare the effectiveness of metacognitive therapy and behavioral activation on depression in the elderly with type 2 diabetes. The results showed that metacognitive therapy and behavioral activation were significantly effective on depression in this population with type 2 diabetes. Moreover, behavioral activation was more effective than metacognitive therapy on depression reduction.
Background and Objectives:Adolescence is a critical period of social, psychological, and physical development. Adolescents make important choices about health, growth, attitudes, and health behaviors that will affect their adulthood. Therefore, this research was conducted to compare the effectiveness of dialectical behavior therapy and metacognitive therapy on attachment styles and dimensions of identity transformation in adolescents. Materials and Methods:This semi-experimental study was performed with a pretest-posttest follow-up design and a control group. The research population included all adolescent girls aged 13 to 16 years in District 1 of Baharestan City who were studying in the seventh to tenth grades in the academic year of 2022-2023 and were referred to the education counseling center in 2022. Out of this population, three groups of 20 people were selected using the availability sampling method and randomly divided into experimental and control groups. The required data were collected through Hazan and Shaver's (1987) Attachment Styles Questionnaire and Berzonsky’s Identity Style Inventory(1992) in three pre-test, post-test, and follow-upstages. The subjects in the experimental groupsunderwent dialectical behavior therapy and metacognitive therapy inone 60-minute session per week; however, the control groupreceived no training. The data were statistically analyzed in SPSS software using the repeated measures ANOVA. The significant level was considered < 0.05. Results: The results were indicative of the significant effects of dialectical behavior therapy and metacognitive therapy on attachment styles (P=0.017) and the dimensions of identity transformation (P=0.023). Conclusion: According to the results of this research, the goal of dialectical behavior therapy and metacognition therapy was to increase behaviors that would probably lead to a safe and healthy attachment style and healthy identity transformation in adolescents, and these rewards are internal or external.
