Three experiments were conducted to test a model of attributional bias in counseling diagnosis. The model predicted that (a) available helping resources influence diagnostic attributions and (b) this effect is mediated by the effect resources have on the diagnostician's perception of his or her helping role. In each experiment, undergraduates served as diagnosticians in a simulated referral agency. Referral resouces for half of the subjects were oriented toward dealing with personal problems; resources for the other half were oriented toward dealing with situational problems. In referring each client, subjects indicated whether they perceived the problem to lie with the client (a dispositional atrribution) or with his social environment (a situational attribution). As predicted, subjects with person‐oriented resources were more likely to perceive clients' problems to be dispositional than were subjects with situation‐oriented resources. Results of Experiment 3 indicated that this effect was mediated by the influences resources had on subjects' perception of their helping role.
