title: Using facebook to maximize follow-up response rates in a longitudinal study of adults who use methamphetamine.
abstract: This study examines the process and effects of using facebook (FB) to locate and re-contact study participants targeted for follow up in a longitudinal study of adult methamphetamine users (N = 649). A follow-up interview was conducted in 2009-11 approximately 8 years after previous study participation. Our paper describes re-contact efforts involving FB, including IRB regulatory issues and the effectiveness of using FB compared to mailings and phone calls. A total of 48 of the 551 surviving non-incarcerated participants who agreed to be contacted for follow up studies were contacted via FB, of whom 11 completed the follow-up interview. Those contacted through FB were more likely to be younger, female, relocated out-of-state, and reported somewhat higher rates of anxiety and cognitive problems compared to those not located on FB. Although participants contacted through FB are likely to differ demographically from those contacted by phone or mail, FB provides a potentially effective means to expand conventional methods of correspondence for contacting hard to reach participants.
