Physical abuse, sexual victimization, and illicit drug use: replication of a structural analysis among a new sample of high-risk youths.

Mounting evidence of serious adverse consequences of childhood physical and sexual abuse has important implications for public health officials and care providers. Given the potential impact on social policy of this area of inquiry, programmatic research is needed for the validation of theoretical models across populations and over time. This study, based on a sample of high-risk youths, replicates a structural model that specified the influence of child physical and sexual abuse on self-derogation and drug use. Results suggest that for male and female youths, physical abuse and sexual victimization had a direct effect on self-derogation and illicit drug use, and an indirect effect on drug use that was mediated by self-derogation. Moreover, structural coefficients for the model were found to be identical across gender. Subsequent analyses demonstrated the equivalence of the structural model of child physical and sexual abuse on drug use across two study cohorts. Implications for the identification and treatment of youths in high-risk groups are discussed.
