About this trial
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.

Treatments tested in this trial
The OurRelationship Program
BehavioralA guided self-help program for couples delivered online over 10 weeks. Participants complete structured learning modules and engage in planned couple conversations focused on improving communication, problem-solving, and emotional connection. Each couple receives support from a trained coach through five scheduled telephone or video calls. The program is designed to be flexible and completed at the couple's own pace within the 10-week period.
Bibliotherapy
BehavioralAn unguided self-help program for couples using the Danish book "Take Care of Your Relationship" \[Pas på Parforholdet\] and an accompanying reading guide. Couples are encouraged to read assigned sections, engage in planned couple conversations, and apply strategies for improving relationship functioning. The intervention is self-paced and completed over 10 weeks without guidance from a coach or therapist.
Treatment groups
Trial outcomes
Primary outcomes
Communication Conflict Scale
A 7-item self-report measure assessing how couples handle conflict (e.g., "Small issues suddenly became big arguments"), scored from 1 (Often) to 4 (Never), with higher scores indicating better conflict management. Developed for the Administration for Children and Families Supporting Healthy Marriage Initiative
Secondary outcomes
The Strengths and Difficulties Questionnaire (SDQ) - impact score
The 4-item section of the parent-reported SDQ in which the parent assesses the extent to which a child's difficulties cause distress and interfere with everyday life, scored from 0 (Not at all) to 2 (A lot), with higher scores indicating worse impact.
Other outcomes
Couple Satisfaction Index-4
A 4-item self-report measure of overall relationship satisfaction, scored from 0 (Not at all / Not at all true) to 5 (Completely / Completely true), with higher scores indicating greater satisfaction.
Responsive Attention Scale
A 10-item self-report measure of perceived partner responsiveness, scored from 1 (Very rarely) to 5 (Very often), with higher scores indicating greater responsiveness.
Intimate Safety Questionnaire
A 4-item self-report measure of perceived safety and comfort with one's partner, scored from 0 (Never) to 4 (Always), with higher scores indicating greater intimacy.
Major Depression Inventory
A 10-item self-report measure of depressive symptoms, scored from 0 (None of the time) to 5 (Always), with higher scores indicating worse symptoms.
