Relationships between psychiatric symptoms, functioning and personal recovery in psychosis

Abstract

Background: Recovery from psychosis is increasingly being viewed as a combination of symptomatic, functional, and personal recovery. Negative and depressive symptoms have been linked to community functioning, and negative affect has been linked to personal recovery. The current study examines differential associations of symptoms with functional and personal recovery, and the interaction of cognitive and emotional components of psychotic experiences in predicting recovery.

Methods: Baseline data from four studies of individuals with schizophrenia-spectrum disorders were amalgamated for the current analyses. All studies utilized the Positive and Negative Syndrome Scale, Psychotic Symptom Rating Scale, Personal and Social Performance Scale, and the Questionnaire about the Process of Recovery.

Results: 971 individuals participated across the four studies. Affective symptoms were most strongly associated with personal recovery, accounting for 30% of the variance in personal recovery and only 2% of the variance in objective functioning. Negative and disorganized symptoms were related to both functional and personal recovery, excitement symptoms were only related to personal recovery, and broad measures of positive symptoms were not associated with either functional or personal recovery. Cognitive interpretations of psychotic experiences were more strongly related to objective functioning, and emotional components of psychotic experiences were more strongly related to personal recovery; cognitive interpretations moderated the relationship between emotional characteristics and recovery measures.

Conclusions: Functional and personal recovery are distinct domains of recovery with differential relationships to symptomatology. Interventions that target cognitive interpretations of psychotic experiences and negative affect may be more likely to affect multiple domains of recovery.
