NCT07125118

Brief Summary

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.

Study Arms (3)

The OurRelationship Program

EXPERIMENTAL

Participants assigned to this arm complete a guided self-help program for couples that includes online learning modules, structured couple conversations, and support from a trained coach through five scheduled calls.

Behavioral: The OurRelationship Program

Bibliotherapy

Waitlist

NO INTERVENTION

Participants receive no intervention during the study period and are offered access to the OurRelationship Program or Bibliotherapy after the follow-up assessment.

Interventions

A 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.
