We propose that commitment is a prerequisite in highly satisfied couples, fostering relationship maintenance behavior such as positive dyadic coping. Method: Structural equation models identified the relationship between commitment, relationship satisfaction, and dyadic coping with data from 201 heterosexual couples with an average relationship length of 34 years. Results: The common fate model confirmed that relationship satisfaction mediated the effects between commitment and dyadic coping on a latent dyadic level. Additional analyses revealed that women’s satisfaction was mainly responsible for mediating effects between both partners’ commitment and dyadic coping. Conclusions: Findings support the essentiality of commitment for couples’ maintenance strategies and for consistency in long-term relationships. </jats:p> application/pdf https://sonar.ch/global/documents/121831 eng info:eu-repo/semantics/altIdentifier/doi/10.1024/1662-9647/a000112 info:eu-repo/semantics/altIdentifier/issn/1662-9647 info:eu-repo/semantics/openAccess GeroPsych. - Hogrefe Publishing Group. - 2014, vol. 27, no. 4, p. 139-149 Gerontology Geriatrics and Gerontology Commitment and Dyadic Coping in Long-Term Relationships http://purl.org/coar/resource_type/c_6501
