Maltreatment, attachment, and substance use in adolescence: Direct and indirect pathways.

Abstract

Past research indicates that maltreatment increases risk for adolescent substance use; however, research is limited on how attachment between adolescents and their parents influences this relationship. The present study examined psychological and physical maltreatment, attachment avoidance and attachment anxiety, and substance use (i.e., cigarettes, alcohol, marijuana, and other drugs ) among adolescents between the ages of 12 and 18 (N\u202f=\u202f737; 59.3% female; Mage\u202f=\u202f14.69, SD\u202f=\u202f1.46). Psychological maltreatment was significantly related to cigarettes, alcohol, and marijuana use, and physical maltreatment was related to cigarette and marijuana use. Exposure to both forms of maltreatment was also associated with increased attachment avoidance and attachment anxiety, but only attachment avoidance predicted substance use. Indirect paths indicated that attachment avoidance mediated the relationship between psychological maltreatment and cigarette (B\u202f=\u202f0.14, CI [0.001, 0.314]) and alcohol use (B\u202f=\u202f0.09, CI [0.011, 0.188]). Attachment avoidance also mediated the relationship between physical maltreatment and cigarette (B\u202f=\u202f0.15, CI [0.031, 0.311]) and alcohol use (B\u202f=\u202f0.09, CI [0.027, 0.185]). No significant mediated effects for attachment anxiety emerged. Attachment avoidance may increase risk for substance use because youth have a lower rate of disclosing their activities to their parents, and do not seek or accept their guidance. Instead, they may turn to peers who also engage in substance use as a source of support. Interventions designed to increase parent-teen attachment security and decrease attachment avoidance may be particularly useful in reducing risk for substance use.
