Masuda et al. [107] | USA | Psychological disorders | College students | 95 (43 + 52) | The CAMI scores for the educational workshop lowered at post-intervention and 1-month follow-up among participants with higher levels of psychological flexibility (scored 67 or higher on the Acceptance and Action Questionnaire) | CAMI administered at beginning and end of workshop, and at 1-month follow-up |
Boulay et al. [108] | Ghana | HIV | General public | 2746, 2926 | Attitudes related to a punitive response to PLHA both improved over time and were positively associated with exposure to the program’s campaign; overall, respondents exposed to the campaign were 45% more likely than those not exposed to be willing to care for a HIV-infected relative, and 43% more likely to believe that an HIV-infected female teacher should be allowed to continue teaching | |
Peters et al. [109] | Indonesia | Leprosy | Community in an endemic district | 213 and 375 | Knowledge about leprosy increased and that negative attitudes reduced significantly; at baseline, 87% considered leprosy curable and 31% thought leprosy was still contagious after treatment; this had improved after the contact event to 98% and 7%, respectively | Post-intervention result measured after 3 months |
Contact | ||||||
Peters et al. [109] | Indonesia | Leprosy | Community in an endemic district | 213 and 375 | The EMIC and SDS stigma scores reduced both among those attending ‘contact events’ (effect sizes 0.75 and 0.81, respectively) and in the wider community (effect size 0.47 and 0.54) | Contact was through testimonies on video plus a live testimony given at ‘contact events’ with community groups; post-intervention results were measured on average 1–1.5 years after the contact events |
Corrigan et al. [110] | USA | Mental illness | College students | 257 | Participants in the contact intervention group showed significant reduction in avoidance and segregation factors with the Attribution Questionnaire at post-intervention and 1-week follow-up; participants in contact condition also showed significant reduction in pity and improvement in power from pre- to post-intervention | Contact through video was used; measures administered pre-test, post-test, 1-week follow-up |
Paxton [137] | ? | HIV | Young people | 1230 | HIV-positive speakers were effective in decreasing fear and stigmatization among the audience; meeting HIV-positive people decreased fear and prejudice, reinforced messages about protective behavior and increased the belief that HIV is preventable; the improved attitudes remained significant over 3 months | |
Uys et al. [71] | Lesotho, Malawi, South Africa, Swaziland, Tanzania | HIV | Nurses PLHA | 41 PLHA 134 nurses | PLHA involved in the intervention teams reported less stigma and increased self-esteem; nurses in the intervention teams and those in the target group reported no reduction in stigma or increases in self-esteem and self-efficacy, but their HIV testing behavior increased significantly | A pre- and post-test was done to measure stigma, self-esteem and self-efficacy; the post-test was conducted within 1 month after the intervention |
Yiu et al. [111] | Hong Kong | HIV | Nursing students | 89 | In both the knowledge-only group and the knowledge-contact group, significant improvement in AIDS knowledge, stigmatizing attitudes, fear of contagion, willingness to treat, and negative affect were found at post-test; the effects on AIDS knowledge, fear of contagion, willingness to treat, and negative affect were sustained at follow-up for both groups Intergroup comparisons at post-test showed that the effectiveness of the knowledge-contact program was significantly greater than the knowledge program in improving stigmatizing attitudes; no significant difference between the two groups was found at follow-up | |

Cross & Choudhury [76] | Nepal | Leprosy | Community | 152 SHG participants | The Stigma Elimination Programme had a significant impact at community level and is recognized as a positive force by district level officials of Her Majesty’s Government of Nepal; as direct effects of SHG activity, 1060 people have had some basic education, many people now have access to clean water, some have the benefits of improved sanitation and others have improved physical access to amenities, over 200 people are now generating income from their own micro enterprises | |

Li et al. [78] | China | HIV | Healthcare workers | 1750 POL | Reduced prejudicial attitudes (estimated difference = – 2.40; p < 0.001), reduced avoidance intent towards people living with HIV (estimated difference = – 1.10; p < 0.001), and increased institutional support in the hospitals (estimated difference = 0.39; p = 0.003) at 6 months after controlling for service providers’ background factors and clinic-level characteristics | The intervention effects (6 months) were sustained and strengthened at 12 months |
