The Effectiveness of Couple Therapy and Relationship Support: a Randomized Controlled Trial
This randomized and controlled study investigates the effectiveness of relationship counselling and couple therapy in improving couples' relationship satisfaction and overall well-being. It compares four intervention groups both with each other and with a waitlist control group. The groups are:
- HUS Self-Help (Mielenterveystalo.fi): Participants independently complete online self-help tasks based on couple therapy, developed by Helsinki University Hospital (HUS) Psychiatry and Väestöliitto.
- Peloton Parisuhde (eng. Fearless Relationship) Online Course: Based on Emotionally Focused Couple Therapy (EFCT), this course by EFCT trainers Eklund-Mikola & Pinomaa uses online lectures and exercises to help couples identify negative interaction patterns and strengthen their emotional connection.
- Short Manualized Emotionally Focused Couple Intervention: Five face-to-face sessions with a couple therapist.
- Face-to-Face Couple Therapy (Treatment As Usual): 1 to 10 sessions, with the therapeutic approach varying depending on the therapist's training.
The study is conducted at the Relationship Counselling Unit of the City of Helsinki's Social Services in Finland, which provides counselling and family guidance under Section 26 of the Social Welfare Act to couples with children living in Helsinki. A total of 200 couples from the unit's treatment queue will be invited to participate and randomly assigned to one of the interventions or the control group, with 40 couples in each group.
Participants will complete questionnaires at the beginning and end of the service, and at a 4-month follow-up. The questionnaires measure relationship satisfaction and well-being, among other things. The study also examines how individual, couple-level, and treatment-related background factors influence and mediate the effectiveness of the interventions.
In addition to the questionnaires, registry data, therapist assessments, and ongoing treatment feedback collected within the unit is utilized. The results will provide new scientific insights into the effectiveness of short interventions and their suitable target groups and can be used to develop relationship counselling work both within the unit and nationally.
