This study used data gathered over the course of a New Zealand longitudinal study (N = 924) to examine the relationships between measures of parental bonding and attachment in adolescence (age 15-16) and later personal adjustment (major depression; anxiety disorder; suicidal behaviour; illicit drug abuse/dependence; crime) assessed up to the age of 30. Key findings included: 1) There were significant (p less than 0.05) and pervasive associations between all measures of attachment and bonding and later outcomes. 2) Structural equation modelling showed that all measures of bonding and attachment loaded on a common factor reflecting the quality of parent/child relationships in adolescence. 3) After adjustment for covariates there were modest relationships ([beta] = 0.16-0.17) between the quality of parent/child relationships in adolescence factor and later adjustment. The study findings suggest that the quality of parent/child relationships in adolescence is modestly related to later psychosocial functioning in adulthood. (Contains 2 tables and 1 figure.)
