We recruited 1,702 students from seven high schools in five school districts in southeast Texas for the current study.

We discarded seven surveys due to severely inconsistent responses, which yielded a total of 1,042 study participants. Because of the low number of students in the 11th grade (n = 11) and of those who reported their race or ethnicity as Asian (n = 38), American Indian (n = 5), multi-racial (n = 20), or “other” (n = 40), these students were also excluded from the present analyses, leaving those students who were in the 9th or 10th grade and who were Caucasian, African American, or Hispanic/Latino.
