Joëlle Darwiche, Cindy Eira Nunes, Laura Vowels, Esther Liekmeier, Jean‐Philippe Antonietti

TL;DR
This study explores how parent couples' relationships change after therapy, finding different patterns of improvement or decline over a year.
Contribution
The study identifies distinct post-therapy trajectories and factors influencing them in parent couples.
Findings
Therapy gains were largely stable over time, with some improvements in child adjustment.
Five distinct post-therapy trajectories were identified based on individual distress and relational functioning.
IBSI was associated with more favorable trajectories, while younger or more children linked to less optimal patterns.
Abstract
This study examined post‐therapy trajectories among parent couples who received either the Integrative Brief Systemic Intervention (IBSI)—targeting both romantic and coparenting relationships—or Brief Systemic Therapy as usual (BST‐as‐usual). Based on previous results showing comparable post‐treatment improvements across conditions, participants were analyzed together to identify the typical patterns of change couples follow after therapy. We assessed whether distinct trajectory groups could be identified over the 1‐year follow‐up and examined whether treatment‐related variables (therapy condition, number of sessions) and family characteristics (relationship duration, blended family status, number of children, age of youngest child) predicted group membership. Of the 101 Swiss randomized parent couples, 85 (44 IBSI, 41 BST‐as‐usual) provided data at post‐therapy, 6‐month, and 1‐year…
