This project will examine how multiple biological measures from the brain and the body's stress response system contribute to anhedonia (the loss of pleasure) in adolescence. The goal of this project is to see if it is possible to combine these biological measures to describe different patterns of activity in the brain and body that adolescents may have in response to stress. The main question this study aims to answer is whether different patterns of activity in the brain and body are related to whether adolescents develop anhedonia and how high or low levels of anhedonia are over time. This study will enroll 192 adolescents who are between 13 and 15 years. Adolescents will complete tasks three times: at the beginning of the study, 10 months after that, and then 10 months after that. In total, they will be part of the study for 20 months. At each time, adolescents will complete surveys, provide samples of spit to measure hormones and provide pictures of their brain to measure brain activity, participate in mildly stressful tasks, and complete different activities that measure how they think. The investigators will also ask each adolescent's parent or legal guardian to answer some surveys about themselves and their child.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
