This is an open enrollment study to collect data for the optimization of smartphone-based algorithms for the early detection of mental health and suicidal risk in a student population. Approximately 2000 students, ages 8-23, will be recruited by therapists across 30 schools and mental health centers.

Inclusion Criteria:

• Currently a client receiving services from mental health agency at a school or outpatient, or at a college/university counseling center
• Age ≥ 8 years and < 23years
• Able to provide informed consent, parental permission or assent
• English as a primary language

Exclusion Criteria:

• Participants with communication disorders (linguistic or articulation)
• Any minor participants for whom parental or legal guardian consent cannot be obtained.
• History of any other serious medical or psychiatric condition that would interfere with the ability of the patient to complete the study or would make it ethically unfeasible to enroll them
• Participants with an intellectual disability that the therapist deems a barrier to participation

Thirty sites across Southwest Ohio will be recruited, including schools (using the school-based therapists), community mental health centers, and colleges/universities (counseling centers). Approximately 150 therapists across 30 sites will be recruited to enroll students from their current caseloads.
