Online recruitment of a non-help-seeking sample for an internet intervention: Lessons learned in an alcohol-exposed pregnancy risk reduction study

摘要

BackgroundRecruiting a hidden population, such as the population of women at risk for alcohol-exposed pregnancy (AEP) who binge drink and are at risk of an unintended pregnancy, is challenging as this population is not typically seeking help or part of an identifiable group. We sought to identify affordable and efficient methods of recruitment for hidden populations.
