Precision psychiatry: thinking beyond simple prediction models - enhancing causal predictions.

Area of Science:

• Psychiatry
• Data Science
• Clinical Decision-Making

Background:

• Precision psychiatry relies on individualised outcome predictions for informed clinical decisions.
• Current prediction models in psychiatry use associative algorithms, overlooking causal structures and temporal dynamics.
• These associative models often yield predictions that are not actionable at an individual level.

Purpose of the Study:

• To present a general framework for causal and actionable predictions in psychiatry.
• To introduce counterfactual explanations as a method to advance predictive modeling.
• To address the limitations of current associative models in psychiatric research.

Main Methods:

• Overview of a general framework for causal inference in predictive modeling.
• Application of counterfactual explanations for actionable predictions.
• Conceptual demonstration with a concrete example.

Main Results:

• The proposed framework aims to generate predictions that are actionable for individual patients.
• Counterfactual explanations offer a pathway to understand the causal impact of interventions or features.
• The study highlights the translational implications for advancing psychiatric predictive modeling.

Conclusions:

• Moving beyond associative models to causal frameworks is crucial for actionable precision psychiatry.
• Counterfactual explanations can enhance the interpretability and utility of psychiatric prediction models.
• This approach holds significant potential for improving clinical decision-making and patient outcomes.
