The aim of present study was to compare the effects of acceptance and commitment therapy and schema therapy on problem solving styles in heart patients. The research method was quasi-experimental with a pre-test-post-test and two experimental groups and one unbalanced control group. The statistical population of the study included all patients with heart diseases referred to the Nuclear Medicine Center in 2017 in Tehran for diagnostic examinations and cardiac scans. The study sample consisted of 45 people (15 people in the acceptance and commitment therapy group, 15 people in the schema therapy group and 15 people in the control group). They were selected by a non-random convenience sampling method and were randomly allocated to three groups. To collect research data, Cassidy and Long (1996) standard problem solving styles questionnaire (Aga Yousefi and Sharif, 2011) was used. After performing the pre-test for all three groups, the experimental groups received acceptance and commitment treatment protocol (Wells and Sorrell, 2007; Mesgarian, 2012) for 12 sessions (1 session per week of 120 minutes) and the schema therapy protocol (Young et al., 2012; Hamidpour and Andoz, 2012) for 10 sessions (1 session per week of 120 minutes).
The present study aimed at evaluating the effectiveness of group-based acceptance and commitment therapy on self-regulation of maladjusted couples. This study was conducted by using a quasi-experimental method with pre-test-post-test design with a control group. The statistical population of the study included maladjusted couples in the age range of 20 to 50 years in Districts 4 and 5 of Tehran. Among them, 80 people were selected by a convenience sampling and they were randomly assigned to experimental and control groups. A self-regulation inventory (25 questions) was used to collect data and according to the research design, the subjects were assessed in two stages of before and after the group training. The treatment program was performed for 7 sessions of 90 minutes for the couples in the experimental group, but the control group received no intervention during the study. The collected data were analyzed using multivariate analysis of variance in SPSS-26 software. Results revealed that self-regulation scores and their dimensions in the experimental group increased significantly compared to the control group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
