Abstract

A cohort of 585 patients with internalising disorders is being recruited to investigate to cognitive-behavioural therapy.

  • Less than 50% of patients with internalising disorders achieve clinically meaningful improvement after cognitive-behavioural therapy.
  • The study aims to identify bio-behavioural signatures associated with treatment non-response (TNR).
  • Emotion regulation is considered a key mechanism in both cognitive-behavioural therapy and treatment non-response.
  • State-of-the-art machine learning methods will be utilized for single-patient predictions based on high-dimensional neuroimaging data.
  • The research seeks to enhance precision psychotherapy by establishing optimal predictors of treatment outcomes.
