Brief Summary
The purpose of this experiment is to determine whether social buffering by friends of stress physiology remains effective later in puberty when friends share the load versus when they provide support but are not undergoing the stressor with the target child. There are four conditions: (1) Friend and Target both undergo the stressor, (2) Friend provides support but does not undergo the stressor, (3) Unfamiliar Peer and Target undergo the stressor, and (4) Alone (no partner).

Outcome Measures
Primary Outcomes (2)
Cortisol AUCi
Cortisol response to the TSST, measured as Area Under the Curve, increase from baseline. 7 Samples were taken during the course of the assessment, at (1) arrival for training purposes; (2) after the calming video, 30 minutes after arrival; (3) after 5 minutes of speech preparation; (4) after 10+minutes of speech and math performance; (5) 15 minutes after sample 4; (6) 10 minutes after sample 5; (7) 10 minutes after sample 6. Area under the curve at intercept (AUCi) is calculated using samples 2-7 with sample 2 as the intercept.
2 hours
sAA AUCi
Salivary Alpha Amylase response to the TSST, measured as Area Under the Curve, increase from baseline. 7 Samples were taken during the course of the assessment, at (1) arrival for training purposes; (2) after the calming video, 30 minutes after arrival; (3) after 5 minutes of speech preparation; (4) after 10+minutes of speech and math performance; (5) 15 minutes after sample 4; (6) 10 minutes after sample 5; (7) 10 minutes after sample 6. Of those, samples (2, 4, 5) are assayed for salivary alpha amylase (sAA) in micrograms per milliliter. Area under the curve at intercept (AUCi) is calculated using samples 2, 4, 5 with sample 2 as the intercept.

Limitations and Caveats
Note that while parents consented and completed questionnaires about their family or child, they are never the focus of analysis or considered enrolled in the study. They are consenting to their child's enrollment and reporting on their child's environment, health, and behavior.
