The Investment Model: Its Antecedents and Predictors of Relationship Satisfaction

Intimate relationships are an integral part of our lives, but the rate of relationship breakups is high. We explored the role of the investment model and the traits that influence investments on relationship satisfaction among 146 volunteers (age M = 28.76 years, SD = 10.23). Relationship satisfaction was predicted by investments, which in turn were predicted by attachment, personality and love style. Clinicians working with individuals or couples with relationship issues may benefit from knowing how invested they are in the relationship and their love style. Insight into imbalances in these constructs between partners may be used to facilitate relationship satisfaction.
