1. Describe the study design you will employ in order to determine if your intervention has had an effect on the outcome variable of interest.
The overall outcome of interest is increased enrollment of high risk populations in HIV vaccine research. A more specific outcome of interest for this intervention is to increase awareness and education of HIV vaccine research by distributing an easily comprehensible video widely.
A potential study can be done after the initial evaluation of the video. We can recruit participants from Gay and Lesbian organizations to take a pre and post-video survey that attempts to quantify HIV vaccine knowledge obtained through the video. We can also assess the survey participants likelihood of participating in future research after the video.
2. Define the unit-of-analysis for your main outcome evaluation, the minimum meaningful effect size, and the sample size necessary to detect this effect size.
The unit of analysis would points on a survey of HIV vaccine research knowledge. The meaningful effect size would be at least 15 points difference between pre and post tests. This makes my sample size be 150 participants for both the pre and post tests.
