Brief summary
This is a pragmatic, non-inferiority, randomized controlled trial comparing the effectiveness of two methods (crowdsourcing versus social marketing) for creating one-minute videos promoting condom use among MSM and TG in China. Crowdsourcing is the process of shifting individual tasks to a large group, often involving open contests and enabled through multisectoral partnerships.
Detailed description
Crowdsourcing may be a powerful tool to spur the development of innovative videos to promote condom use among key populations such as men who have sex with men (MSM) and transgender (TG) individuals. The purpose of this randomized controlled trial is to compare the effect of a crowdsourced video and a social marketing video on condom use among Chinese MSM and TG who report condomless anal sex during the past three months. The crowdsourced video was developed using an open contest, formal transparent judging, and several prizes. The hypothesis is that a crowdsourced video will not be inferior (within a margin of 10%) to a social marketing video in terms of condomless sex at three to four weeks (with an additional follow-up at three months) of watching the video.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Frequency of condomless sex following the assigned video intervention (3 wk) | 3 weeks following the video | Frequency of men, defined as those who report condomless sex over the 3 week period divided by the total number of men who watched the video |
| Frequency of condomless sex following the assigned video intervention (3 month) | 3 months following the video | Frequency of men, defined as those who report condomless sex over the 3 month period divided by the total number of men who watched the video |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Male condomless sex | 3 weeks and 3 months after baseline | Frequency of men, defined as number of men who reported condomless anal sex with a man divided by the total number of men who viewed the video in that arm. |
| Post-video condomless sex | 3 weeks after baseline | Frequency of men, defined as number of men who reported condomless vaginal or anal sex with any partner immediately following the video intervention divided by the total number of men who viewed the video in that arm |
| Frequency of sex acts | 3 weeks and 3 months after baseline | Frequency of men, defined as the number of men who had decreased total number of sex acts in the three weeks following the intervention compared to the three weeks immediately preceding the intervention in that arm |
| Condom self-efficacy | 3 weeks and 3 months after baseline | Frequency of men, defined as number of men who had an increase in self-efficacy when comparing self-efficacy during the three weeks before baseline and the three weeks after the baseline, will measure again at 3 months and then compare baseline and three month data |
| Incremental cost | 3 weeks after baseline | Incremental cost, defined as the cost associated with respective video interventions per individual who reported no sex or sex with a condom during the follow-up period. |
| Condom use negotiation | 3 weeks and 3 months after baseline | Frequency of men, defined as the number of men who attempted to convince an unwilling partner to use a condom immediately following the video intervention divided by the total number of men who viewed the video in that arm |
| HIV testing | 3 weeks and 3 months after baseline | Frequency of men, defined as the number of men who reported being tested for HIV during the interval between watching the video and following up compared to the number of men who followed up |
| STI testing | 3 weeks and 3 months after baseline | Frequency of men, defined as the number of men who reported being tested for STIs (excluding HIV) during the interval between watching the video and following up compared to the number of men who followed up |
| Condom use social norms | 3 weeks and 3 months after baseline | Frequency of men, defined as number of men who report higher levels of social norms when comparing their pre-intervention and post-intervention condom use norms. |
| Female condomless sex | 3 weeks and 3 months after baseline | Frequency of men, defined as number of men who reported condomless vaginal or anal sex with a woman divided by the total number of men who viewed the video in that arm. |
