Clinical and psychosocial factors associated with depression in patients with psychosis according to stage of illness

초록

Aim This study investigated the clinical characteristics and psychosocial factors associated with depression in patients with early psychosis according to stage of illness. Methods The present study includes patients who fulfil the DSM-5 criteria for schizophrenia spectrum and other psychotic disorders. Patients were divided into two groups according to illness stage (the acute stage of first-episode psychosis and stabilization phase of recent-onset psychosis). Clinically meaningful depression was defined as moderate or severe on the depression dimension of the Clinician-Rated Dimensions of Psychosis Symptom Severity scale in the DSM-5. Results In total, 340 (207 first-episode and 133 recent-onset) patients were recruited in this study. Patients with comorbid depression were characterized by frequent suicidal ideation, a past suicide attempt, and lower scores on the Subjective Well-being Under Neuroleptics and Brief Resilience Scale in both groups. Long duration of untreated psychosis and higher scores on the Early Trauma Inventory Self Report were associated with depression in the acute stage of first-episode psychosis. In the stabilization phase of recent-onset psychosis group, a monthly income and scores for sexual desire and on the Family Adaptability and Cohesion Evaluation Scale-III were significantly lower in patients with depression than in those without depression. Conclusion Comorbid depression was associated with high suicidality, lower quality of life and poor resilience in patients with first-episode and recent-onset psychosis. Depression was associated with factors that had been present before the initiation of treatment in patients with first-episode psychosis and with environmental factors in those in the stabilization phase.
