The relationship of childhood abuse history and substance use in an Alaska sample

This study confirms a strong link between childhood abuse history and substance misuse based upon data obtained from an ethnically diverse (largely Alaska Native) sample of 192 pregnant women in substance misuse treatment in the mid-1990s. Nearly three-quarters of the women reported childhood victimization. Compared to women with no abuse history, abused women were significantly younger at the age of onset of substance misuse, used substances more frequently, had experienced more blackouts, had more family members with substance-misuse concerns, were more likely to have been raped, revealed more psychological problems, and had less formal education. Risk patterns differed slightly for women with physical versus sexual abuse histories, with the experience of physical violence having a stronger relationship with adulthood problem behaviors than the experience of sexual molestation. Overall, findings suggest an interactive cycle of violence and substance misuse that begins very early in childhood, especially for women who were physically abused, and continues in adulthood, though no cause-end-effect conclusions can be drawn. Treatment and prevention implications of these findings are discussed.
