Using a life-span developmental psychology model of positive personality adjustment, this study had two aims. First, this study aimed to compare additive and threshold cumulative models of personality adjustment after divorce. The cumulative effect hypothesis states that the number of indicators is a more accurate predictor of an outcome than any…

This paper considers the functions of supportive individuals in the lives of community college and 4-year college students and how such support can promote hope, defined as agency and pathways thinking. We surveyed 181 college students regarding their supportive relationships and found that parents were most likely to be nominated as a primary…

This study tested the association between parent illicit drug use disorder (DUD) in early adulthood and observed parenting practices at ages 27-28 and examined the following 3 theoretically derived models explaining this link: (a) a disrupted parent adult functioning model,(b) a preexisting parent personality factor model, and (c) a disrupted…

The relationship between complexity and usefulness can be captured by a U-shaped curve. This comment explores that relationship. Complexity may be useful for one of the main aims of developmental psychology (causal inference) but not for another (description of developmental phenomena). Currently, developmentalists conduct complex analyses that…

Longitudinal data analysis has long played a significant role in empirical research within the developmental sciences. The past decade has given rise to a host of new and exciting analytic methods for studying between-person differences in within-person change. These methods are broadly organized under the term "growth curve models." The…

This study examined alcohol use development from ages 13-20 years. The sample comprised 256 youth (50.4% female; 51.2% White, 48.8% African American) assessed annually for 6 years. A cohort-sequential latent growth model was used to model categorical alcohol use (non-use vs. use). Covariates included gender, race, income, parent marital status,…

Most youth in America have a good chance of becoming productive members of adult society. However, for a particular group of young people, at-risk youth, the probability of maturing into responsible adulthood is less certain. "At-risk youth" is a term commonly used to describe those adolescents for whom there is a high probability (risk)…

Stage-state analysis of the life course is presented as useful in identifying types of life courses and their relative frequency, in estimating the likelihood of moving from a given state through a sequence of future states, and in analyzing routes and processes connecting initial states with potential outcomes.
