Attachment in Young Adults and Life Satisfaction at Age 30: A Birth Cohort Study

Satisfying close relationships are associated with higher levels of life satisfaction throughout the life course. Despite the fundamental role of attachment style in close relationships, few studies have longitudinally examined the association between attachment style in young adults with later life satisfaction.

Data from 2,088 participants in a longitudinal birth cohort study were examined. At 21-years, participants completed the Attachment Style Questionnaire which comprises five domains reflective of internal working models of interpersonal relationships and attachment style: confidence (security), discomfort with closeness and relationships as secondary (avoidance), need for approval and preoccupation with relationships (anxiety). At 30-years, participants self-reported their overall life satisfaction. Linear regression was used to longitudinally examine the association between attachment domains at 21-years and life satisfaction at age 30.

After adjustments, confidence was positively associated with life satisfaction (β = 0.41, 95% CI 0.25–0.56, p < 0.001), while need for approval was negatively associated with life satisfaction (β = -0.17, 95% CI -0.30 – -0.04, p < 0.001). Low income at 21, caring for a child by age 21, and leaving the parental home at 16-years or under were negatively associated with life satisfaction at 30-years.

Young adult attachment style is associated with later life satisfaction, particularly through confidence in self and others. Promoting positive internal working models of interpersonal relationships and fostering greater confidence in self and others in adolescence may be an effective strategy for improving life satisfaction later in life.
