Participants read details of a hypo-thetical sexual assault of a female minor and of an adult. Expert testimony of his risk assessment consisted of clinical opinion versus structured-clinical judgment (SCJ) versus actuarial assessment. Participants perceived clinical-opinion and SCJ testimony as equally influential when forming judgments of future dangerousness. In the context of treatment, however, participants relied on actuarial testimony when judging potential for risk. In addition, attributional complexity (AC) moderated perceptions of sexual risk. Overall, results point to the need for continued refinement of assessment techniques when determining dangerousness and need for treatment. Key words: risk assessment, expert testimony, future dangerousness
