An exploratory evaluation of predictors of duration of untreated psychosis in first-episode psychosis in lower income patients

A longer duration of untreated psychosis (DUP) may adversely affect the course and impact of the illness. Little is known about predictors of duration of untreated psychosis in lower socioeconomic strata (SES) in urban India. We examined variables associated with DUP in 60 urban lower SES patients diagnosed with first-episode, untreated psychosis. Instruments used included the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF), the UCLA Social Attainment Scale (SAS), and the Stigma Subscale from the Family Interview Schedule. The mean age of the sample was 30.5 years. The sample was 50% male. Most patients (90%) were living in a nuclear family. The median DUP was 120 days. DUP was 6 months in 31.7% of the sample and 2 years in 23.3%. A third of the sample had been taken to faith healers before being brought into medical care. DUP was not significantly associated with age, sex, religion, education, family history of mental illness, marital status, employment status, income, substance use, PANSS subscale and total scale scores, and GAF scores. Presence of an antecedent stressor, acute onset of psychosis, presence of medical co-morbidities, lower stigma scores, and higher SAS scores were significantly associated with shorter DUP.
