The joint impact of parental psychological neglect and peer isolation on adolescents' depression.

Adolescents receive psychological or emotional care from both parents and peers, which is crucial for mental health at this stage. Little research has been undertaken to evaluate the experience and consequences of caregiver psychological neglect during adolescence. Less is known about the unique and combined impacts of neglectful experiences with parents and peers. The purpose of this study was to evaluate the relationship between exposure to caregiver psychological neglect and isolation from peers with depression for a population of at-risk adolescents. A sample of 2776 adolescents who represent a cohort population of adolescents in contact with Child Protective Services in the U.S. was studied. Data come from the National Survey of Child and Adolescent Well-being (NSCAW) and are pooled across four waves representing seven years duration. Structural equation modeling with latent variables was used to estimate within-time associations. A two-stage-least squares path model was used to determine within-time reciprocal effects between depression and neglectful experiences. Adolescents who are emotionally neglected by their primary caregivers and are isolated from peers have substantially increased depression, a combined standardized effect of 0.78-0.91. Isolation from peers is more impactful for depression compared to psychological neglect by caregivers. The effects of deficits in these two primary sources of emotional support explain 40 percent of the variation in depression. The relationships between depression and peer isolation and depression and psychological neglect are reciprocal, but the primary direction of effect is from neglectful experiences to depression.
