Most research on mental health in individuals with autism spectrum disorder (ASD) and intellectual disability (ID) has focused on deficits. We examined individual (i.e., sociocommunicative skills, adaptive behavior, functional cognitive skills) and contextual (i.e., home, school, and community participation) correlates of thriving in 330 youth…

Risk behaviors such as substance use or deviance are often limited to the early stages of the life course. Whereas the onset of risk behavior is well studied, less is currently known about the decline and timing of cessation of risk behaviors of different domains during young adulthood. Prevalence and longitudinal developmental patterning of…

The transition to adulthood is characterised by both great potential for positive change and a relatively high incidence of problem outcomes. A multidimensional model of positive development during the transition to adulthood (at 19-20 years) has recently been proposed. However, an unresolved question regarding the nature of positive development…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

This study examines the predictive significance of late adolescent substance use groups (i.e., abstainers, experimental users, at-risk users, and abusers) for early adult adaptation. Participants (N = 159) were drawn from a prospective longitudinal study of first-born children of low-income mothers. At 17.5 years of age, participants were assigned…

In one study, a comparison of 42 high school juniors with 42 delinquent adolescents showed that delinquents have less successful task resolutions. In a second study of 175 seventh graders, twelfth graders, and college freshmen, juniors, and seniors, older students and those with low dysfunctional attitudes had better task resolutions. (SLD)

Examined whether relationship seriousness influenced youths' sexual behaviors and attitudes. Found that interpersonal context influenced sexual timetables of whites more than other groups. Some ethnic differences in sexual timetables were diminished when sociodemographic factors were controlled. Youth generally began sexual activities with a…

Examined the extent to which risk factors for concurrent binge drinking in adolescence can predict changes during transition to young adulthood. Found that being male, possessing low self-efficacy, and drinking primarily "to get drunk" were unconditional risk factors for increased binge drinking over time. Other adolescent risk factors…

Background: It has been proposed that ADHD is an executive control disorder. Little is known however about the maturation of executive control in ADHD. Method: A cross-sectional study of ADHD patients compared to normal controls tested on a computerized neurocognitive test battery. Participants: 175 patients with ADHD, age 10 to 29, compared to…

Examined links between the match between adolescents' developmental stage and the family and community environment and their psychosocial outcomes, implications for later outcomes, and impact of adolescent diabetic status. Found that even after controlling for psychosocial factors during adolescence, the benefits of developmental match were…

"On the Frontier of Adulthood" reveals a startling new fact: adulthood no longer begins when adolescence ends. A lengthy period before adulthood, often spanning the twenties and even extending into the thirties, is now devoted to further education, job exploration, experimentation in romantic relationships, and personal development. Pathways into…
