METHOD: This systematic review used the preferred reporting items of Systematic Reviews and Meta-Analyses (PRISMA). We conducted a systematic review of randomized controlled and quasi-experimental studies published from the establishment of the database to October 2022. Marital self-disclosure interventions were conducted with both cancer patients and their spouses. Studies published in a language other than English or Chinese, and studies below a quality grade of C were excluded. Data were extracted through a standardized data collection form, and two reviewers independently extracted and evaluated the data. The quality of the included studies was assessed using the Cochrane Handbook of Systematic Reviews of Interventions, and a third reviewer adjudicated in case of disagreement. The data were synthesized by vote counting based on direction of effect according to the Synthesis Without Meta-analysis (SWiM) reporting guideline.
RESULTS: Thirteen studies were included in the review. Based on quality evaluation, three studies were categorized as grade A (good), and ten studies were grade B (moderate). Seven studies reported moderate rates of participant refusal and attrition. The structure and topics of marital self-disclosure varied across different studies. The five studies had various prespecified disclosure topics, such as fear of cancer recurrence, benefit finding, and emotional distress. The overall results suggest that marital self-disclosure interventions can improve physical and psychological health, enhance marital relationships, and increase self-disclosure ability.
CONCLUSION: The limited number of studies, small sample sizes, diverse intervention strategies, and methodological heterogeneity weakened the evidence base for the effectiveness of marital self-disclosure interventions. Therefore, further high-quality randomized controlled trials (RCTs) are recommended to confirm the effectiveness of such interventions. These studies should also evaluate the interventions' long-term impact, analyze optional topics and methods, identify key features, and explore the development of the best intervention program.
METHOD: The study followed a single-blind parallel group in a randomized controlled trial using an experimental longitudinal design, comprising 72 heterosexual couples living in Shiraz, Iran, with a 1-7-year marital age and no severe marital problems. The experimental group received eight consecutive O-GPIs via the Zoom platform, while the control group received information related to parenting skills via email. The outcome measures were the three patterns of communication: (i) constructive communication; (ii) demand-withdraw communication; and (iii) mutual avoidance communication-the screening measure was the dyadic adjustment scale.
RESULTS: The findings indicated that O-GPI could improve couples' constructive communication significantly (45% for husbands and 40% wives) and decrease their total demand-withdrawal (51% for husbands and 65% wives) and mutual avoidance communication (60% for husbands and 62% wives).
LIMITATIONS: Due to the homogenous nature of the sample, generalizations should be made with caution.
CONCLUSIONS: This study demonstrates the feasibility and effectiveness of the online Gottman's psychoeducational intervention to improve couples' communication patterns.
