Agreement Between Self-Rated and Clinically Assessed Symptoms in Subjects With Psychosis

Abstract

The aim of this study was to explore the capacity of acutely ill patients with psychosis (N = 40) to self-report their symptoms by comparing self-assessment and objective measures. Positive, negative, and depressive symptoms were rated using the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Calgary Depression Scale. Insight level was measured using the Scale to Assess Unawareness of Mental Disorder. Patients were asked to self-report positive, negative, and depressive symptoms using the Community Assessment of Psychic Experience. Patients presenting with acute psychotic disorders are able to assess fairly their positive, negative, and depressive symptoms. Significant associations were found between self-reported and objective measures of positive, negative, and depressive symptoms independently of insight level. Individual positive and negative symptoms were correctly self-assessed, except for persecutory delusion and alogia, respectively. These results suggest that self-report questionnaires can be used in educational programs to favor the patient's therapeutic adherence.
