EFCT vs. BCT for Depression and Anxiety in Married Couples

Detailed Description:

This randomized controlled trial (RCT) is designed to compare the effectiveness of Emotion-Focused Couples Therapy (EFCT) and Behavioral Couples Therapy (BCT) in reducing depression and anxiety symptoms among married couples. The study will involve 150 married couples aged between 18 and 65, who have been married for at least one year, have no current psychiatric diagnosis, and are not undergoing any form of psychological therapy at the time of recruitment. Recruitment will be conducted through advertisements, social media platforms, and referrals from community centers and family counseling services in Istanbul.

Study Design:

The study will follow a parallel-group design with a 1:1:1 allocation ratio. After an initial screening process, participants will complete a sociodemographic form and two standardized psychological assessments: the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory (BAI). Based on the assessment results, 60 couples with high levels of depression and anxiety symptoms will be selected for the intervention phase. A computer-generated randomization process will assign 20 couples to the EFCT group, 20 couples to the BCT group, and 20 couples to a control group that will not receive therapy during the study period.

Intervention Protocol:

The EFCT intervention will consist of 12 weekly therapy sessions, each lasting 50 minutes, facilitated by trained clinical psychologists experienced in EFCT. The therapy will focus on enhancing emotional expression, addressing attachment-related insecurities, and fostering emotional bonding between partners. The EFCT framework will follow the standard intervention model, encompassing the three stages of de-escalation, restructuring of interactions, and consolidation.

The BCT intervention will also include 12 weekly 50-minute sessions, focusing on modifying maladaptive behavioral patterns, improving communication, and developing effective problem-solving skills within the relationship. The BCT approach will be guided by the established protocols emphasizing behavioral exchange, communication training, and cognitive restructuring techniques.

The control group will not receive any therapeutic intervention during the 12-week study period but will be offered counseling sessions after the completion of the study to ensure ethical integrity and participant well-being.

Assessment Timeline and Outcome Measures:

Participants will undergo assessments at four key time points:

Baseline (Pre-Intervention): Before the first therapy session, all couples will complete the BDI-II and BAI.

Mid-Intervention: After the 6th therapy session, the BDI-II and BAI will be administered again to evaluate initial changes in depression and anxiety levels.

Post-Intervention: Upon completion of the 12th therapy session, participants will complete the BDI-II and BAI to measure the immediate effects of the intervention.

Follow-Up: Three months after the final therapy session, couples will complete the BDI-II and BAI to assess the sustainability of the therapeutic outcomes.

Data Collection and Management:

Data will be collected using paper-based forms and subsequently entered into a secure electronic database by research assistants. Double data entry will be implemented to minimize errors. All data will be anonymized, and participants will be assigned unique identification codes to ensure confidentiality. The principal investigator will oversee data management and ensure adherence to the study protocol.

Data Analysis Plan:

Statistical analysis will be conducted using SPSS software (version 28.0). Repeated measures ANOVA will be employed to examine within-group and between-group differences over time, focusing on changes in BDI-II and BAI scores. Post-hoc tests (Bonferroni correction) will be used to identify specific differences between the EFCT, BCT, and control groups at each assessment point. Effect sizes (Cohen's d) will be calculated to determine the magnitude of therapeutic effects. Missing data will be handled using multiple imputation methods to maintain the integrity of the dataset.

Ethical Considerations:

The study has received ethical approval from Üsküdar University (Reference number: 61351342/020-675) on December 29, 2024. All participants will provide written informed consent prior to participation. Confidentiality will be maintained throughout the study, and participants will have the right to withdraw at any time without any consequences. The study adheres to the ethical guidelines outlined in the Declaration of Helsinki.

Clinical Significance:

This study aims to provide empirical evidence on the comparative effectiveness of EFCT and BCT in alleviating depression and anxiety symptoms in married couples. The findings are expected to contribute to the development of evidence-based therapeutic interventions in marital counseling, highlighting the potential benefits of both emotion-focused and behavioral approaches in improving mental health and relationship quality.
