Depression, Alcohol Abuse, and Alcoholism in One versus Two Parents and the Implications for Child Attachment and Self-Regulation in Infancy through Adolescence.

This study's purpose was to determine whether the influence of combined parental disorders can cause greater frequency in the occurrence of insecure child attachment and dysfunctions in self-regulation as opposed to the influence of one parent having a disorder. The research design is a quantitative meta-analysis that combined effects from 10 studies to establish differences in the frequency of occurrence for insecure child attachment and dysfunctions in self-regulation through an examination of Cohen's d. Global analysis of Cohen's effect (d) indicated that children being reared by two disordered parents had higher frequency in occurrence of insecure attachment and self-regulation dysfunction than those children reared by only one disordered parent. By addressing the issues surrounding the child population where both parents are disordered, children would have a better chance at healthy development by way of interventions that minimize the occurrence of child psychopathology and foster improvements in the social and overall human condition.
