When these relationships become distressed, the consequences often extend beyond the couple, affecting families and the communities. Despite growing research on factors associated with couple relationships, much of the existing evidence is limited to the US and English\u2010speaking populations, underscoring the need for studies in other contexts, such as Spanish\u2010speaking couples. Our sample included 68 heterosexual, Spanish\u2010speaking couples from Argentina, Costa Rica, Guatemala, Mexico, and Spain. We examined how differentiation of self and attachment experiences uniquely predicted four dimensions of dyadic adjustment: satisfaction, consensus, cohesion, and affectional expression. We utilized an Actor\u2010Partner Interdependence Model (APIM), complemented by a Monte Carlo simulation\u2010based power sensitivity analysis. Overall, higher differentiation (i.e., lower emotional reactivity and cutoff) was associated with greater consensus and affectional expression, while higher attachment anxiety and avoidance were linked to decreased satisfaction, cohesion, and affectional expression. Our findings emphasize the complex interplay between romantic partners' differentiation of self, attachment experiences, and relationship well\u2010being. Findings suggest that clinical interventions aimed at enhancing differentiation of self and addressing attachment insecurity may improve relationship functioning. Future research should explore these dynamics in more diverse samples and cultural contexts to further understand the nuances of the current findings and refine clinical interventions for couples.<\/jats:p>","DOI":"10.1111\/famp.70105","type":"journal-article","created":{"date-parts":[[2025,12,30]],"date-time":"2025-12-30T11:22:29Z","timestamp":1767093749000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Differentiation of Self, Attachment Experiences, and Dyadic Adjustment: An APIM Approach With Spanish\u2010Speaking Couples"],"prefix":"10.1111","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9334-4379","authenticated-orcid":false,"given":"Min","family":"Xu","sequence":"first","affiliation":[{"name":"University of San Diego  San Diego California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7117-0045","authenticated-orcid":false,"given":"Marti\u00f1o","family":"Rodr\u00edguez\u2010Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Psychology Universidad de Navarra  Pamplona Spain"},{"name":"Institute for Culture and Society Universidad de Navarra  Pamplona Spain"},{"name":"Institute for Health Research (IdiSNA) Recinto de Complejo Hospitalario de Navarra  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2394-910X","authenticated-orcid":false,"given":"Mar\u00eda","family":"Calatrava","sequence":"additional","affiliation":[{"name":"Institute for Culture and Society Universidad de Navarra  Pamplona Spain"},{"name":"Institute for Health Research (IdiSNA) Recinto de Complejo Hospitalario de Navarra  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2513-9853","authenticated-orcid":false,"given":"Alessandra","family":"Sambuceti\u2010Lewis","sequence":"additional","affiliation":[{"name":"Department of Psychology Universidad de Navarra  Pamplona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Pilar","family":"Mart\u00ednez\u2010D\u00edaz","sequence":"additional","affiliation":[{"name":"Department of Psychology Universidad Pontificia Comillas  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/14681994.2021.2003320"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471\u20102288\u201014\u2010118"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaac.2016.04.018"},{"key":"e_1_2_10_5_1","volume-title":"Family Therapy in Clinical Practice","author":"Bowen M.","year":"1978"},{"key":"e_1_2_10_6_1","volume-title":"Attachment and Loss: Vol. 1.
