Participants came from a large, on-going longitudinal study of the behavioral and emotional health of college students at a public university in the mid-Atlantic (Dick et al., 2014). The present report uses data from the August 2014 project data release. Baseline and follow-up data were collected on three consecutive cohorts during the fall and the spring, respectively, of participants' first year of college via on-line surveys administered using REDCap software (Harris et al., 2009). For the baseline assessment, incoming first-year students 18 years of age or older were invited via email to complete the survey starting one week before their arrival on-campus up until the tenth week of the fall semester. Of the 10,497 individuals who were eligible to complete the study's baseline fall assessment, 6,120 participated (58% response rate, cohort 1 n = 2055, cohort 2 n = 2038, cohort 3 n = 2027. Of these, 38% were male, 61% were female, 1% declined to identify sex. The sample reflected the population from which it was drawn: 51% White, 19% African-American, 16% Asian, 6% Hispanic/Latino, 8% other/multi-race/unknown/declined to respond. The average age at assessment was 18.42 years.
