Ethical Dimensions of Predictive Algorithms in Psychiatric Risk Assessment

Abstract

Predictive algorithms trained on health records and passively collected behavioral data are increasinglyused to estimate a patient's  risk of suicide, violence, or psychiatric crisis, often outperforming unstructured clinical judgment on retrospective measures.
This policy analysis reviews four recurring concerns in the recent literature: the gap between validation-set accuracy and real clinical utility, demographic bias inherited from historically skewed psychiatric data, the ambiguous privacy status of digital phenotyping, and the use of risk scores in involuntary treatment decisions. Existing mental health legislation and consent practices were largely written without algorithmic inputs in mind, leaving clinicians and tribunals with little guidance on how much weight a machine-generated score should carry. We argue that predictive accuracy is necessary but not sufficient, and that disclosure, fairness auditing, and
a genuine mechanism for contesting a score need to be built into deployment from the outset. We close with recommendations for narrowing the gap between what these tools can do and what responsible clinical and legal use of them requires.
