Loss to follow-up (LTF) is an important issue that can affect the validity of longitudinal studies. Further, LTF among adolescent study participants may be predicted by variables such as substance use, educational attainment, and demographic information. The purpose of this study was to determine if alcohol or marijuana use, high school completion, or demographic information was correlated with LTF among adolescent participants in the Real Talk Study. The Real Talk study is a randomized control trial that employs a brief motivational interview intervention in a clinical setting to reduce perpetration of teen dating violence (TDV) in Boston. Current participants of the Real Talk study who were eligible for follow up comprised the study sample (N=127). Baseline characteristics on age, gender, race/ethnicity, high school completion, alcohol use, and marijuana use were analyzed using Pearson’s Chi Square, and the level of significance set to p < 0.10. A post-hoc analysis was conducted on frequency of alcohol use using Pearson’s Chi Square. Of the total sample, 13% were LTF (n=17). The results of the analyses indicated that there was a statistically significant difference between those LTF and those retained for gender and drinking 6 or more drinks of alcohol per occasion. Females were more likely to be LTF than males (p<0.10), and those participants who responded “never” or “less than monthly” to the question, “how many times do you drink 6 or more drinks per occasion?” were more likely to be retained, or less likely to be LTF (p<0.10) than those who responded differently. While some of the results were consistent with the literature, it is also possible that the follow-up procedure for Real Talk ensured that there were minimal differences in LTF.
