The Effect of Acceptance and Commitment Therapy Intervention on Caregiver Burden in Caregivers of Schizophrenia Patients

Overview

The aim of this study was to learn the effects of Acceptance and Commitment Therapy based stress management program on psychological flexibility and caregiver burden in caregivers of schizophrenia patients. This study is a randomized controlled trial. The main questions it aims to answer are: * Does an acceptance and commitment therapy-based stress management program increase psychological flexibility in caregivers of patients with schizophrenia? * Does an acceptance and commitment therapy-based stress management program reduce caregiver burden in caregivers of schizophrenia patients? * What is the relationship between the level of psychological flexibility and care burden? Researchers will compare the intervention with a control group (no intervention) to see if an acceptance and commitment therapy-based stress management program increases psychological resilience and reduces caregiver burden in people with schizophrenia. Participants will participate in the Acceptance and Commitment Therapy Based Stress Management Program, consisting of 6 sessions, one session per week, each session lasting 45 minutes. The intervention group will visit the clinic at the end of the application (after 6 weeks), at 1 month, 2 months and 3 months to be administered the Psychological Flexibility Scale and the Caregiver Burden Scale. They will do the homework given in the therapy program.

Approximately 25-50% of schizophrenia patients worldwide, and 70% of schizophrenia patients in Asia, live with their families. Schizophrenia-related symptoms affect the individual as well as their family and caregivers. The severity of disease symptoms and the decrease in productivity of patients increase the care burden of family members and affect their physical and psychological health. Caring for patients with schizophrenia is a difficult, sensitive, and time-consuming responsibility. Caregiving creates social, emotional, behavioral, and financial problems for caregivers and causes various limitations in their personal lives. Caregivers of patients with schizophrenia are at serious risk of caregiver burden and psychiatric morbidity.Caregivers of schizophrenia patients experience high levels of caregiver burden and stress. It has been reported that family interventions reduce the relapse rate and hospitalization time in schizophrenia, and increase the duration of remission. Therefore, implementation of interventions that reduce the caregiver burden is very important to provide the best care for the patient, while also preventing mental illnesses that may develop in family caregivers. Developing stress coping methods and psychological flexibility of caregivers of schizophrenia patients with an acceptance and commitment therapy-based stress management program may be effective in reducing the caregiver burden. It is thought that with the implementation of this program, caregivers will develop more effective coping behaviors against stress, and in parallel, the risk of caregiver burden, stress, and mental illness will decrease. This research is a randomized controlled trial to determine the effects of an individual Acceptance and Commitment therapy-based stress management program on psychological flexibility and caregiver burden in caregivers of schizophrenia patients. Research Hypothesis/Hypotheses H1. At the end of the application of the acceptance and commitment therapy based stress management program, there is a difference between the intervention and control group psychological flexibility scores. H2. At the end of the application of the acceptance and commitment therapy based stress management program, there is a difference between the intervention and control group care burden scores. H3. At the end of the application of the acceptance and commitment therapy based stress management program, there is a difference between the intervention and control group care burden scores in the first, second and third months. H4. At the end of the application of the acceptance and commitment therapy based stress management program, there is a difference between the intervention and control group psychological flexibility scores in the first, second and third months. The Universe and Sample of the Study The universe of this study will consist of the caregivers of patients diagnosed with schizophrenia who were hospitalized in Sivas Hospital and Sivas Cumhuriyet University Application and Research Hospital psychiatry clinic between March 22, 2024 and March 01, 2025. The number of patients to be included in the study sample was determined by performing power analysis with the G-Power 3.1.9.4 sample volume calculation program. Accordingly, when the standard deviation was one, the effect size was 0.76, the significance level was 0.05 and (1-β)=0.80, the power of the study was calculated as 0.80678. The sample size will consist of the caregivers of 60 patients. 30 of the caregivers will form the intervention group (n1) and 30 will form the control group (n2). Measurement Tools Used in the Study 1. Personal Information Form: 2. Psychological Flexibility Scale: 3. Caregiver Burden Scale: 4. DISCERN (Quality Criteria for Consumer Health Information) Scale: It was to be used in the evaluation of the content and quality of educational materials. The DISCERN measurement tool, which consists of three sections, includes 16 questions that question the content of the material. Obtaining Expert Opinions A total of 5 expert opinions were obtained regarding the acceptance and commitment therapy-based stress management guide, including 3 faculty members specialized in psychiatric nursing, 1 faculty member specialized in public health and 1 faculty member specialized in clinical psychology. The experts were asked to evaluate the prepared guide in accordance with the Written Materials Appropriateness Evaluation Form and the DISCERN Scale. The expert opinions evaluated with the DISCERN Scale were analyzed. The intervention program was finalized in line with the opinions. The preliminary application of the research was carried out and changes were made regarding the aspects that needed to be adjusted. Research Process The research will be conducted in the psychiatry clinics of Sivas Hospital and Sivas Cumhuriyet University Hospital. Caregivers of schizophrenia patients receiving inpatient treatment will be interviewed in the interview room of the psychiatry clinic between the research dates. Consent forms will be obtained from those who want to participate in the study and the study will be conducted on caregivers who meet the participation criteria. Individuals who agree to participate in the study will be assigned to the intervention and control groups through randomization. The first interview will be conducted with the intervention and control groups and the Psychological Flexibility Scale, Caregiver Burden Scale and Personal Information Form will be filled out. The intervention group will be informed about the program and its goals. The Acceptance and Commitment Therapy Based Stress Management Program consisting of 6 sessions, 1 session per week and each session lasting 45 minutes, will be applied to the intervention group. The purpose of the research will be explained to the control group and it will be stated that the scales will be applied at certain intervals within the scope of this research and measurements will be made simultaneously with the intervention group. No program will be applied to the control group during the application and follow-up periods. At the end of the application (after 6 weeks), the psychological flexibility scale and the caregiver burden scale will be applied to the intervention and control groups in the 1st month, 2nd month and 3rd month. Data Analysis The data obtained from our study will be loaded into the Statistical Package for the Social Sciences program (Ver: 22.0) and when the parametric test assumptions are met (Kolmogorov Smirnov), Variance Analysis, Bonferroni test, significance test of the difference between two means will be used in repeated measurements, and when the parametric test assumptions are not met, Friedman test, Wilcoxon test, Mann Whitney U test and Chi-square test will be used and the error level will be taken as 0.05.
