This document summarizes a researcher's experiences recruiting and retaining participants for a longitudinal qualitative study on the experiences of male intimate partners of female rape victims in South Africa. The researcher conducted a pilot study from February to July 2008 and a main study from August 2008 to August 2009. Several challenges were encountered, including participants preferring off-site interviews, a language barrier, and retention issues. Tracking strategies like frequent contact, safety measures, incentives, and preparation for termination helped address these difficulties and retain nine of sixteen main study participants. The researcher documented these lessons to inform best practices in longitudinal qualitative research.
