Aspects of our study that may have contributed positively to recruitment, and are consistent with the literature on effective recruitment strategies [1] include: the inclusion of monetary incentive upon completion, a relatively low-risk intervention, as well as a potential previous knowledge or recommendation of the study drug. However, specific aspects that strongly influenced the positive impact that social media had on recruitment include the fact that our study was a health-seeking study targeting a population–likely young to middle-aged women–who are active users of social media platforms and are often using the internet as the first point in seeking this information. The marked impact of social media may not have been as significant if we were targeting an elderly population or patients suffering from certain chronic disease states. Thus, factors such as age, generational demographics and scope of internet access will inevitably define the reach, relevance and efficiency of social media as a recruitment source.
