Reactions toward mental, physical, and substance-abuse disorders

In this study, participants read 3 separate vignettes describing a hypothetical sibling with each of the following disorders: substance abuse, schizophrenia, and a physical illness. As hypothesized, and consistent with attribution theory, the hypothetical patient with a substance-abuse disorder was perceived as having the most control over his or her illness and the associated symptoms, and the patient described as having a physical illness was perceived as having the least control over his or her illness. Also in support of attribution theory, the hypothetical patient described as having a substance-abuse disorder elicited the most negative emotional reactions from participants, and the patient described as having a physical illness elicited the least negative emotional reactions. Again in support of attribution theory and study hypotheses, participants reported the most willingness to help a physically ill hypothetical sibling.
