Abstract: This study examines source credibility of violence risk assessments made using two methods: actuarial assessment and structured professional judgment (SPJ).Data were collected in an online study of violence risk to a university population (N =174).Source credibility (Meyer, 1988) was evaluated as an antecedent variable to Eagly and Chaiken's (1993) heuristic-systematic model (HSM) of information processing.The impact of motivation for accurate information was assessed.Source credibility of violence risk assessment methods was similar on a superficial level but different underlying structures were detected.Analysis of the full model revealed notable differences in model fit when source credibility factor scores (x 2 = 16.693,P = .005,Negelkerke R 2 = .124)were included in the model.Accuracy motivation was predictive of risk decisions (J3 =.602, CI = [.412,.880],P < .054).Results indicate that both perceived credibility of the method and motivation for accurate information impact risk judgments.
