Childhood inhibition predicts adolescent social anxiety: Findings from a longitudinal twin study.

An enduring issue in the study of mental health is identifying developmental processes that explain how childhood characteristics progress to maladaptive forms. We examine the role that behavioral inhibition (BI) has on social anxiety (SA) during adolescence in 868 families of twins assessed at ages 8, 13, and 15 years. Multimodal assessments of BI and SA were completed at each phase, with additional measures (e.

The impact of parenting a child with serious mental illness: Accounting for the parent's genetic vulnerability to mental illness.

Parents of adults with serious mental illness (SMI) often are primary caregivers for their affected relative. Prior work has suggested that the toll of caregiving is associated with poorer well-being in family caregivers, particularly parents of affected adults. However, due to methodological limitations, it has not been possible to assess these family caregivers' own genetic vulnerability to mental and physical health problems, and thus the impact of caregivers' genetic risk on well-being may not have been accounted for.

Validating psychosocial pathways of risk between neuroticism and late life depression using a polygenic score approach.

Neuroticism is a stable and heritable personality trait that is strongly linked to depression. Yet, little is known about its association with late life depression, as well as how neuroticism eventuates into depression. This study used data from the Wisconsin Longitudinal Study (WLS; N = 4,877) to examine the direct and indirect effects of neuroticism on late life depression at 3 points in the life course-ages 53, 64, and 71-via stressful life events (i.
