Abstract

Long-term affective bonds are associated with several benefits, with commitment being a key indicator of relationship quality. According to the Investment Model of Relationships, the main factors influencing commitment are satisfaction, investment, and availability of alternatives. Although widely studied, these constructs lack recent systematic syntheses. This study conducted a systematic review with meta-analysis, following PRISMA guidelines, to assess the association between these three factors and romantic commitment. Sixteen articles published between 2016 and 2020 were analyzed, selected from Scopus, Web of Science, PubMed, and PsycInfo databases, with a combined total of 10,644 participants. Results showed that satisfaction had the strongest association with commitment (r = 0.66), followed by investment (r = 0.51) and alternatives (r = –0.41). These findings support the continued validity of the Investment Model, even in light of the psychosocial changes that have shaped romantic relationships in recent decades.
