All participants who enrolled in the study were assigned to the Creativity Camp.

In Summer 2022, participants were 1:1 randomized to "early" (2 weeks before camp, before camp, after camp) or "late" assessments (before camp, after camp, and 2 weeks after camp). This allowed for an approximation of a waitlist-control design, where we compared the changes during the "waitlist" (the two weeks before camp for the "early" group) to the changes during camp for the "active" group (changes from pre to post intervention for the "late" group) and also allowed us to explore short-term durability of effects in the "late" group.

In 2023 and 2025, since MRI was no longer required, clinical data were collected at all 4 time points: 2 weeks before, before camp, after camp, and 2 weeks after camp. This allows for analysis of the data using a "waitlist control" approach while not changing the experience at the level of the participant.

The CDI (2) is a self-report questionnaire completed by child and parent separately. The Child CDI 2 is a 28-item measure of depression symptoms for youth ages 7-17. For each item, participants selected one of three choices that describe the severity of their symptoms over the past 2 weeks. Responses are: 0 (no symptoms), 1 (mild or probable symptoms), or 2 (definite symptoms). The 17-item Parent CDI 2, has four choices per item, ranging from 0 (not at all) to 3 (much or most of the time). For both child and parent reports, higher scores mean more severe depression.

The SCARED is a 41-item inventory of anxiety symptoms rated on a 3-point Likert-type scale. Higher scores mean higher severity of anxiety.
