This study examined change prospectively in autism symptoms and maladaptive behaviors during a 4.5 year period in 241 adolescents and adults with an autism spectrum disorder who were 10-52 years old (mean = 22.0) when the study began. Although many individuals' symptoms remained stable, a greater proportion of the sample experienced declines than increases in their level of autism symptoms and maladaptive behaviors, and there were significant improvements in mean levels of symptoms. Individuals with mental retardation had more autism symptoms and maladaptive behaviors than those without mental retardation, and they improved less over time. Compared to adolescents, older sample members (31 and older) had fewer maladaptive behaviors and experienced more improvement in these behaviors over time.

We investigated how change in the characteristics of 140 adolescents and young adults with an autism spectrum disorder (ASD) would predict subsequent change in maternal well-being and in the quality of the mother-child relationship. Overall patterns of improvement in maternal well-being and mother-child relationship quality were observed during the study. When the son or daughter had declining behavior problems, were prescribed more psychotropic medications, and exited from high school during the study period, mothers' well-being and perception of relationship quality improved to a greater extent. In addition, improvements in maternal well-being and relationship quality were observed in mothers of daughters, in mothers of individuals with mental retardation as well as ASD, and in mothers of those in better health.

We identified 201 individuals who obtained IQs of 85 or below in high school and participated in the Wisconsin Longitudinal Study (a prospective longitudinal study that followed sample members from age 18 through age 53). Their life course development was contrasted with their siblings who obtained IQs above 100. Life course outcomes were assessed in five domains: Education and Occupational Attainment, Family Formation, Social Participation and Support, Physical Health, and Psychological Well-Being. Compared to their higher IQ sibling, low-IQ individuals completed less schooling, had less prestigious occupations, rated themselves less physically healthy, and reported lower levels of psychological well-being. Differences were not evident, however, in patterns of family formation, social support, job satisfaction, or objective measures of physical health.

The current study offers a new way to ascertain information about child neglect by evaluating a self-report measure of neglectful behaviors, the Mother-Child Neglect Scale (MCNS). The scale was modified from an existing self-report measure, the Neglect Scale (NS), which was originally designed to measure personal histories of neglect. One hundred adolescent mothers were administered the MCNS and NS in two occasions via phone interviews. In addition, maternal abuse potential and the quality of mother-child interactions were assessed when children were age 3 and 5 years. The MCNS had high internal consistency and moderate test-retest reliability. Convergent validity was found between the MCNS and maternal histories of neglect as well as observed parenting behaviors and child abuse potential; those relationships remained after social desirability was controlled. This research tool may prove useful, in conjunction with existing assessment instruments, in determining the type and severity of past neglectful behaviors.

The present study examines the role of neglect potential in adolescent mother-child dyads, both in terms of antecedents and its consequences for children's development. Participants were 100 adolescent mother-child dyads who were part of a larger, longitudinal study. Data were collected from the third trimester of pregnancy until the children's 10th year. Histories of maternal neglect and the quality of mother-child interactions during early childhood were found to predict neglect potential during middle childhood. Mothers with high neglect potential had children who exhibited more externalizing problems and fewer adaptive behaviors, with neglect potential mediating the effects of both early abuse potential and the quality of parenting on children's later externalizing behaviors. Results suggest that neglect potential may be a mechanism through which early potential for child abuse and insensitive maternal interactions affect later externalizing problems in children of adolescent mothers.
