A cross-sectional study by Luty et al. [65] found that attitudes towards people with substance use disorders (alcoholism) were not significantly different between participants who received didactic educational factsheets and people who did not (P > 0.05). Luty et al.'s [63] randomized control trial revealed that educational leaflets communicating positive depictions about people with substance use disorders significantly reduced stigmatized attitudes among the general public towards heroin (g = 1.50, SE = 0.13, P < 0.0001) and alcohol (g = 1.25, SE = 0.13, P < 0.0001) dependence. Luty et al.'s [64] third study found that brief motivational interviews conducted with members of the general public moderately decreased stigmatizing attitudes towards people with alcohol dependence (g = 0.44, SE = 0.14, P < 0.01).
