Marital Conflict

This parallel three-arm, single-blind (assessor-blinded), randomized controlled trial (RCT) aims to compare the effects of ACT, CBT, and treatment-as-usual (TAU) on the severity of depressive symptoms (primary outcome), the severity of comorbid anxiety symptoms, marital satisfaction, intimacy with spouse, quality of life, and experiential avoidance (secondary outcomes) among people diagnosed with major depressive disorder (MDD) with marital crisis across four time points (T0 = baseline (pre-intervention), T1 = post-intervention (immediately after completion of the intervention, 8 weeks after its commencement), T2 = follow-up at 12 weeks after completion of the intervention, T3 = follow-up at 24 weeks after completion of the intervention). A total of 120 MDD patients with marital crisis will be recruited from two study sites and randomized by stratified block randomization into three groups (ACT, CBT and TAU) in a 1:1:1 ratio. ACT group therapy will be conducted once a week for 8 weeks in the ACT group, while CBT group therapy once a week for 8 weeks will be carried out in the CBT group. During baseline assessment (T0), the demographic and clinical characteristics, the Chinese versions of the Beck Depression Inventory-II (BDI-II), the Generalized Anxiety Disorder 7-item scale (GAD-7), the Personal Assessment of Intimacy in Relationships (PAIR), the Dyadic Adjustment Scale (DAS), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), and the Acceptance and Action Questionnaire-II (AAQ-II) will be administered to all participants. The re-administration of the BDI-II, GAD-7, PAIR, DAS, WHOQOL-BREF and AAQ-II will be carried out at T1, T2, and T3.

Children whose parents experience high levels of couple distress are at greater risk for emotional, behavioral, and academic problems. This study tests two types of self-help for parenting couples: the OurRelationship program (OR), an online guided program, and couple-focused bibliotherapy (BT), a book-based self-help approach. The investigators will compare these interventions with a waitlist (WL) control group to see which is most effective at reducing communication conflict between partners. They will also examine whether the interventions improve child well-being when problems are present at the start of the study. A total of 350 parenting couples in Denmark will take part. Eligible couples have at least one child under 18 living at home and report high levels of conflict or relationship distress. Couples will be randomly assigned to OR, BT, or WL. Questionnaires will be completed online before the program, after the program (10 weeks later), and at 3- and 12-month follow-ups.

This study is designed to evaluate a preventive intervention program designed to support families (parents and typically developing adolescent siblings) that include a child with an intellectual and/or developmental disability. Participant families will be randomly assigned to either the treatment condition, in which they will receive psychoeducation and communication coaching over a four-week period, or the control condition, in which they will receive self-study materials. All subjects will participate in a pre-test assessment and three post-test assessments over the course of the year.
