Our data derive from a larger prospective study. Participants were students in their 11th year of education who were recruited over 3 years from one school in suburban Chicago, Illinois, and another in suburban Los Angeles, California. For screening, students provided assent and parental consent before completing the neuroticism scale of the revised Eysenck Personality Questionnaire (EPQ-R-N; Eysenck & Eysenck, 1975). Over 3 years, 1,976 students fully completed the screening measure. Participants were paid $10 for the screening phase.
