Adolescent Mood During Puberty and Testosterone

Study Overview
=================
Brief Summary
-----------------
Starting at puberty, female adolescents are nearly three-times more likely to develop internalizing disorders, like depression, while male adolescents are two-times more likely to develop externalizing disorders, like attention deficit hyperactivity disorder (ADHD). This divergence between the sexes during puberty suggests sex-specific pathways of risk and differential effects of sex hormones. The purpose of this research is to determine: 1) sex-specific neural and endocrine features of the pubertal transition that may mediate sex differences in adolescent mood disorders, and 2) the neurophysiological basis of susceptibility to hormone change during puberty.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Healthy Minds Program<br>Participants in this group will begin the Healthy Minds Program immediately following the 4-week baseline period. | Behavioral: Healthy Minds Program<br>* The Healthy Minds Program is a 4-week mobile program to improve coping and emotion regulation skills. It includes 4 training modules corresponding to key pillars of wellbeing: awareness(focused attention/awareness of thoughts/emotions), connection (empathy, compassion, social connection), insight (clarity of identify/experience) and purpose (applying values/motivations). The Healthy Minds Program includes 2 introductory audio lessons and guided meditations, and each 1-week module includes 2 podcast lessons (5-7 minutes) with psychoeducation and practical examples, and 3 guided meditations relevant to the module topic, for a total of 10 lessons and 14 guided meditations.<br>|
| Other: Waitlist Control<br>After the 4-week baseline period, participants in the waitlist control condition will wait an additional 4 weeks before starting the Healthy Minds Program. | Behavioral: Healthy Minds Program<br>* The Healthy Minds Program is a 4-week mobile program to improve coping and emotion regulation skills. It includes 4 training modules corresponding to key pillars of wellbeing: awareness(focused attention/awareness of thoughts/emotions), connection (empathy, compassion, social connection), insight (clarity of identify/experience) and purpose (applying values/motivations). The Healthy Minds Program includes 2 introductory audio lessons and guided meditations, and each 1-week module includes 2 podcast lessons (5-7 minutes) with psychoeducation and practical examples, and 3 guided meditations relevant to the module topic, for a total of 10 lessons and 14 guided meditations.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| CES-DC Score Over Time | The 20-item Center for Epidemiological Studies Depression Scale for Children (CES-DC) will be the primary measure of severity of depressive symptoms. Each item is rated 0 (not at all) to 3 (a lot), with items 4, 8, 12, and 16 being reversed scored. The total CES-DC score may range from 0-60. Higher scores indicate more severe depressive symptoms. Scores of 15 or greater are suggestive of significant depressive symptoms. The overall CES-DC score will be assessed at the end of each week in the study. | up to Week 8 |
