Adaptation of a lay health advisor model as a recruitment and retention strategy in a clinical trial of college student smokers.

This study describes and provides results from a process evaluation of a lay health advisor (LHA) model to enhance participation in a clinical trial of the effectiveness of motivational interviewing on smoking cessation in college fraternity and sorority members. The implementation of the model had two phases: (a) the selection and training of LHAs as liaisons between research staff and participants and (b) LHAs' roles in recruitment and retention. Perceptions of the LHA model were explored using survey questionnaires. Trial participants (N = 118) and LHAs (N = 8) were generally satisfied with the model and identified LHAs as helpful to participation. Seventy-four percent of chapter members were screened and 73% of participants received three of the four motivational interviewing sessions. These results indicate the LHA model was well received and met the needs of the research project.
