Integrating student background data improves mental health screening accuracy. This approach helps identify students needing early intervention services more effectively than single-rater methods.
Area of Science:
- Educational Psychology
- Child and Adolescent Mental Health
- Data Science in Education
Background:
- Many students with mental health needs lack timely support.
- Universal screening is key for early intervention, but current methods are limited.
- Multi-informant assessment is best practice but not applied to universal screening.
Purpose of the Study:
- To develop a Bayesian model for universal mental health screening using student background data.
- To validate cut scores derived from background information.
- To assess the added value of teacher and student self-reports.
Main Methods:
- A Bayesian statistical model was used to incorporate student background information (demographics, referrals, risk statuses).
- Background information generated cut scores in a training sample and were validated in a test sample.
- Sensitivity and specificity were analyzed with and without teacher/student self-reports.
Main Results:
- Incorporating background information significantly improved the accurate identification of students at risk for mental health needs.
- The model demonstrated promise in categorizing students into low, medium, and high-risk groups.
- Background data enhanced the precision of risk identification.
Conclusions:
- Student background information is valuable for accurate universal mental health screening.
- This data-driven approach supports timely identification and intervention for students.
- Future research and practice should consider integrating comprehensive student data for mental health support.

Residuals and Least-Squares Property
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
