Participants were college students recruited to participate in an online
survey from Psychology Department Participant Pools at ten universities across
ten U.S. states. To ensure that data collection was standardized at each site,
all data were collected using the same software (i.e., Qualtrics). To minimize
burden on participants, we utilized a planned missing data design, also known as
matrix sampling (Graham, Taylor, Olchowski,
& Cumsille, 2006 ). Specifically, each participant received and
completed a battery of core measures that focused on substance use (i.e.,
alcohol and marijuana) and the DSM-5 level 1 measure. After completing the core
measures, each participant received a random sample of 10 measures from a larger
pool (19 total measures) that assessed mental health (e.g., depression, anxiety,
stress, self-esteem, suicide, posttraumatic stress), physical health (i.e. sleep
quality, sexual experiences, eating habits), and personality (i.e.,
impulsivity-like traits, Big Five personality traits, antisocial behavior, and
temperament) constructs. Although 7,307 students were recruited across sites,
only data from students that completed the DSM-5 level 1 measure
(n = 7,217) were included in the final analyses. The
majority of the analytic sample was White (73.80%), female (70.54%), and
reported a mean age of 20.85 (Median = 19.00;
SD = 4.74) years. Specific demographic information on our
full sample as well as each data collection site is shown inSupplemental Table 1 . Participants
received research participation credit for completing the study. This protocol
was approved by the institutional review boards at each participating
university.
