Formatted Abstract/Summary
A substantial literature indicates that longer duration of initially untreated psychosis (DUP) is associated with poorer treatment response in early psychosis (EP). Therefore, it is important to identify what factors predict DUP to enable services to effectively intervene to reduce time between psychosis onset and service contact.

To identify predictors of time to service contact in a cohort of EP patients.

The first 6-months treatment of a cohort of patients presenting for first time with psychotic disorder (n451) to 19 mental health teams in 8 area mental health services across three states was evaluated using routine measurement of baseline patient characteristics, treatment guideline concordance, and service models. Cox regression analyses were undertaken to identify predictors of time to service contact.

The multivariate model revealed that, after controlling for all other variables, those patients with an acute mode of onset (as opposed to an insidious onset) experienced, on average, shorter delays into treatment, and those with a schizophrenia spectrum disorder (compared to having another psychotic disorder) experienced longer delays. Those patients treated by services with little or no EP implementation experienced longer DUP than those treated at services with either extensive EP intervention implementation or some EP intervention implementation.

Although services cannot intervene to alter some baseline patient characteristic predictors of DUP, our results suggest that support for a service focus on EP intervention predicts shorter time from psychosis onset to service contact.
