Comparison of measures of functioning for use with treatment-seeking adolescents experiencing attenuated symptoms of psychosis

Aim A growing body of research documents a relation between psychosis risk and functional impairment. Although a general picture of psychosis risk and impaired functioning is emerging, less is known about how different functional measures relate to specific psychosis‐risk symptoms. Methods The current study examines the relative contribution of psychosis‐risk symptoms across multiple measures of functioning in a sample of treatment‐seeking adolescents and young adults. Results Results indicate that different domains of psychosis‐risk symptoms (negative and positive psychotic symptoms, related affective symptoms) contribute differentially to measures of different types of functioning. Conclusion Study of the relation between psychosis‐risk symptoms and different measures of functional impairment can potentially contribute towards a more efficient use of measures of functioning and help inform individualized treatment considerations.
