The project Multiple Opportunities to Reach Excellence (MORE) is a longitudinal community epidemiological study. It was designed to investigate the risk and protective factors associated with alcohol, tobacco, and other substance exposure and use among urban primarily African American children who have been exposed to varying levels (low, moderate, high) of neighbourhood violence. Data sources were comprised of 425 youth (ages 7-13), their parents and teachers, school records, and characteristics of the neighbourhood environment assessed by independent evaluators collected in two annual waves. In this study, we examine the missing data patterns across data sets and informants to explore alternative strategies for dealing with missing data.
