Outcome Measures
Primary Outcomes (3)
Depressive Symptoms
Statistical models including ANOVA and regression will be used to compare changes in depressive symptoms across the four groups. Changes in depressive symptoms will be assessed with the PROMIS Depression Short Form, which has scores that range from 8-40, with higher scores indicating greater depressive symptom severity. PROMIS was measured at baseline, post-intervention (8 weeks), and at a 1-month follow-up. PHQ-8 was administered at baseline as a screening instrument to determine eligibility and was also administered at the 8-week assessment. PHQ-8 was not administered at the 1-month follow-up. This record update corrects an administrative error in the original ClinicalTrials.gov registration, which listed PHQ-8 and GAD-7 as primary outcomes and omitted the PROMIS measures. The IRB-approved protocol dated February 10, 2025, prior to study initiation, specified PROMIS and WHODAS as outcome measures. This update aligns the registration record with the approved protocol.
12 weeks (including 1 month follow up)
Anxiety Symptoms
Statistical models including ANOVA and regression will be used to compare changes in anxiety symptoms across the four groups. Changes in anxiety symptoms will be assessed with the PROMIS Anxiety Short Form, which has scores that range from 7-35, with higher scores indicating greater anxiety symptom severity. PROMIS was measured at baseline, post-intervention (8 weeks), and at a 1-month follow-up. GAD-7 was administered at baseline as a screening instrument to determine eligibility and was also administered at the 8-week assessment. GAD-7 was not administered at the 1-month follow-up. This record update corrects an administrative error in the original ClinicalTrials.gov registration, which listed PHQ-8 and GAD-7 as primary outcomes and omitted the PROMIS measures. The IRB-approved protocol dated February 10, 2025, prior to study initiation, specified PROMIS and WHODAS as outcome measures. This update aligns the registration record with the approved protocol.
12 weeks (including 1 month follow up)
Impairment
Statistical models including ANOVA and regression will be used to compare changes in impairment across the four groups. Changes in impairment will be assessed with the WHO Disability Assessment Schedule (WHODAS 2.0), which has scores that range from 0-100 with higher scores indicating higher levels of impairment. Impairment will be measured at baseline, post 8-weeks of the intervention, and at a 1 month follow up.

Interventions
Mirror is a mobile journaling app developed by the Child Mind Institute (CMI) for youth who want to explore and improve their mental health, particularly addressing symptoms related to depression. The Mirror app enables users to express their thoughts and emotions through multimodal entries (i.e., written, voice, selfie video) and provides prompts to facilitate journal entries using unique, emotionally supportive features to help users identify and process emotions. Users can also complete free-form, unguided journaling, and can complete daily mood tracking and see changes/progress over time.
