Stress Reactivity Study in Adolescents

The TSST was 20 minutes long and consisted of a five-minute instructional period where participants listened to a pre-recorded tape; a five-minute speech preparation period; a five-minute challenging serial subtraction task; and a five-minute videotaped public speaking task in front of a panel of three evaluative, non-affirming judges dressed in white coats.

The 20-minute TSST was replaced with a 20-minute low-affect educational film screening.
