Brief Summary

This study looks at whether using cartoons that reflect the culture of South Africa can help change how young adults there think about HIV/AIDS. This study will test two types of cartoons in a two-arm (treatment, comparator) randomized controlled trial design-one with Black characters and one with White characters-to see how they affect people's attitudes and knowledge about HIV/AIDS. Randomly allocated participants will be Black seronegative South African adults between 18 and 35 years old. This group was chosen because they're a demographic disproportionately affected by HIV, they're at a high point in their lives for shaping and sharing beliefs, and they're also highly active online, which is where this study takes place. The cartoons will show the daily struggles of the protagonist living with HIV/AIDS, and end with a call to action. The study aims to highlight how the characters' ethnicity influences how viewers feel about and remember the message. The investigators want to understand if seeing characters who look like them helps people understand and empathize more. The aim of this study is to learn how cultural representation can improve health communication and guide future efforts to reduce stigma in different communities. Ultimately, the investigators hope this study will contribute to better public health messages and create a more accepting environment for people with HIV/AIDS.

Outcome Measures

Primary Outcomes (2)

  • Attitudes towards HIV

    HIV-related attitudes are measured using Beaulieu et al's SAT-PLWHA-S survey instrument, designed specifically to measure stigmatizing attitudes towards HIV/AIDS. The objective of this questionnaire is to measure participants' own HIV-related behaviors. This measurement uses a 5-point Likert-type scale (from 1 =strongly disagree to 5 = strongly agree) to understand how participants behave when confronted with HIV-related information. Respondents will be asked to answer items such as "Stories featuring diverse ethnic backgrounds make me feel more connected to the content" or "Ethnic diversity in health messages affects my trust in their accuracy". A higher score indicates more positive attitudes and comfort levels regarding HIV and people living with HIV.

    Up to 14 days

  • Health Ethnicity Perceptions

    A composite index measuring participants' perceptions of the relevance, relatability, and trustworthiness of health messages based on the ethnicity of the message source. Items assess how protagonist ethnicity influenced viewers' ability to engage with the content, trust the information, and find the message relatable. 3-item Likert scale index (1-5), with higher scores indicating more positive perceptions of ethnic concordance in health messaging.

    Up to 14 days

Interventions

Thabo cartoonBEHAVIORAL

The animated cartoon features Thabo, a Black South African man living with HIV. Through his narrative, viewers follow his daily experiences managing his condition and confronting societal stigma in a South African context. The story explores his interactions with family, friends, and community members, highlighting both challenges and moments of resilience. The animation concludes with Thabo delivering an anti-stigma message directly to viewers.

Thabo group
Steve cartoonBEHAVIORAL

The animated cartoon follows Steve, a White man living with HIV. His narrative parallels Thabo's, showing his daily experiences managing HIV and facing societal stigma. The story depicts his interactions with family, friends, and community members, presenting the same situations and challenges as in Thabo's story. The animation ends with Steve delivering the same anti-stigma message to viewers.
