Based on previous results showing comparable post\u2010treatment 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\u2010year follow\u2010up and examined whether treatment\u2010related 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\u2010as\u2010usual) provided data at post\u2010therapy, 6\u2010month, and 1\u2010year follow\u2010ups on individual symptomatology, romantic and coparenting relationship quality, and child adjustment. Mixed effects models first indicated that therapy gains were largely stable over time, with some parents reporting improvements in child adjustment, particularly men in BST\u2010as\u2010usual and women in IBSI. Using multiple factor analysis and hierarchical clustering (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200972 couples), we identified five trajectories reflecting different configurations of individual distress and relational functioning. Multinomial logistic regression showed that both treatment characteristics and family context contributed to differentiating these pathways: IBSI was associated with more favorable trajectories, while having younger children or more children was linked to less optimal patterns. Clinically, identifying distinct post\u2010therapy trajectories underscores the importance of monitoring couples beyond treatment termination and tailoring support to those whose individual or family circumstances place them at higher risk of deterioration.\n                  <\/jats:p>","DOI":"10.1111\/famp.70114","type":"journal-article","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T06:10:29Z","timestamp":1769062229000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Post\u2010Therapy Trajectories Following Brief Systemic Couple Therapy for Parents"],"prefix":"10.1111","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9802-3216","authenticated-orcid":false,"given":"Jo\u00eblle","family":"Darwiche","sequence":"first","affiliation":[{"name":"Family and Development Research Center, University of Lausanne  Lausanne Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1614-9622","authenticated-orcid":false,"given":"Cindy Eira","family":"Nunes","sequence":"additional","affiliation":[{"name":"Psychological Sciences Research Institute, Catholic University of Louvain (UCLouvain)  Leuven Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5594-2095","authenticated-orcid":false,"given":"Laura","family":"Vowels","sequence":"additional","affiliation":[{"name":"Family and Development Research Center, University of Lausanne  Lausanne Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7604-6230","authenticated-orcid":false,"given":"Esther","family":"Liekmeier","sequence":"additional","affiliation":[{"name":"Family and Development Research Center, University of Lausanne  Lausanne Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0117-4769","authenticated-orcid":false,"given":"Jean\u2010Philippe","family":"Antonietti","sequence":"additional","affiliation":[{"name":"Family and Development Research Center, University of Lausanne  Lausanne Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,21]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/wics.1246"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1545\u20105300.2006.00191.x"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1037\/0022\u2010006X.73.5.893"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0014405"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/famp.12075"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0025121"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1037\/0893\u20103200.21.2.288"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v061.i06"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0018132"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1037\/0022\u2010006X.74.6.1180"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.48.1.243"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/jmft.12625"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/famp.12773"},{"key":"e_1_2_10_15_1","volume-title":"L'analyse Des Donn\u00e9es \u00e9volutives: M\u00e9thodes et Applications [Analyzing Time Series Data: Methods and Applications]","author":"Dazy F.","year":"1996"},{"key":"e_1_2_10_16_1","volume-title":"Keys to Solution in Brief Therapy","author":"Shazer S.","year":"1985"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.beth.2018.03.011"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00787\u2010022\u201002027\u20101"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1037\/10438-006"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469\u20107610.1997.tb01545.x"},{"key":"e_1_2_10_21_1","volume-title":"Uncommon Therapy: The Psychiatric Techniques of Milton H.
