Latent profile analysis of adolescent temperament: Relations to happiness and health in adulthood

Abstract

AbstractIntroductionThis study provides long‐term evidence that profiles of temperament during adolescence are associated with happiness and health over two decades later.MethodsData are based on the ongoing Fullerton Longitudinal Study, a community‐based sample in the United States. At 14 and 16 years, adolescents (N = 111; 52% male, 90% Euro‐American) and their mothers (N = 105) completed the Dimensions of Temperament Survey‐Revised, a scale designed specifically to assess adolescents' temperament across a set of attributes. When adolescents reached age 38 years in 2017, they completed scales measuring comprehensive happiness and global health.ResultsLatent profile analysis (LPA), a person‐centered approach, was conducted for adolescents' and for mothers' temperament ratings separately. Distinct two‐profile solutions, labeled more regulated and less regulated, emerged for each informant. These were comparable in features across informants. Only the adolescents' self‐rated profiles, controlling for sex and family SES, revealed a conceptually meaningful and statistically significant relation to the distal outcomes of health and happiness two decades later.ConclusionsAdolescents with temperament profiles characterized as more regulated, in contrast to less regulated, reported being happier and healthier upon entering middle adulthood. Implications for intervention are presented.
