Post-Therapy Trajectories Following Brief Systemic Couple Therapy for Parents.

Area of Science:

• Psychology and Family Therapy
• Clinical Psychology
• Relationship Science

Background:

• Parent couples often experience challenges in romantic and coparenting relationships.
• Previous research indicated comparable outcomes between Integrative Brief Systemic Intervention (IBSI) and Brief Systemic Therapy (BST)-as-usual post-treatment.
• Understanding long-term couple trajectories after therapy is crucial for sustained relationship health.

Purpose of the Study:

• To identify distinct post-therapy trajectories in couples over a 1-year follow-up.
• To examine predictors of these trajectories, including treatment type and family characteristics.
• To inform clinical practice regarding post-treatment monitoring and support for at-risk couples.

Main Methods:

• A 1-year follow-up study of 85 Swiss parent couples (initially 101) who received IBSI or BST-as-usual.
• Mixed effects models analyzed changes in individual symptomatology, relationship quality, and child adjustment.
• Multiple factor analysis and hierarchical clustering identified distinct couple trajectories.

Main Results:

• Therapy gains remained largely stable, with some improvements in child adjustment noted.
• Five distinct trajectories were identified, reflecting varying levels of individual distress and relational functioning.
• IBSI was linked to more favorable outcomes, whereas younger or more children predicted less optimal patterns.

Conclusions:

• Distinct post-therapy trajectories highlight the heterogeneity of couple recovery.
• Treatment characteristics (IBSI) and family context (number/age of children) significantly influence long-term outcomes.
• Monitoring couples post-therapy and tailoring support are essential for preventing deterioration, especially for high-risk families.
