Research on the effectiveness of short-term education programs in changing
societal attitudes about mental illness has been mixed. Education efforts s
eem to be mediated by characteristics of the program participants, This stu
dy determines whether the effects of a specially prepared, semester-long co
urse on severe mental illness are mediated by pre-education knowledge about
and contact with severe mental illness, Eighty-three participants who were
enrolled in either a course on severe mental illness or general psychology
completed the Opinions about Mental Illness Questionnaire before beginning
the course and at completion. Research participants also completed a pre-
and posttest of knowledge about mental illness and a pretest on their conta
ct with people who have severe mental illness, The education program had po
sitive effects on some attitudes about mental illness. Interestingly, the e
ffects of education group interacted with pre-education knowledge and conta
ct and varied depending on attitude. Participants with more pre-education k
nowledge and contact were less likely to endorse benevolence attitudes afte
r completing the education program. Participants with more intimate contact
showed less improvement in attitudes about social restrictiveness. Implica
tions of these augmentation and ceiling effects are discussed.
