Abstract
Purpose
To investigate whether duration of untreated psychosis (DUP) and duration of untreated illness (DUI) are associated with measures of both subjective and objective recovery 10 years after a first episode of psychosis.
Methods
A cohort of 65 clients from an early psychosis intervention program completed a battery of outcome measures 10 years following initial treatment for first-episode psychosis (FEP). The outcomes of interest were self-perceived recovery scores (Maryland Assessment of Recovery in People with Serious Mental Illness Scale) and occupational activity, defined as engagement in work and/or school on a full/part-time basis. Multiple linear and logistic regression analyses were used to estimate the associations between DUP and DUI with each measure of recovery, adjusting for potential confounding factors.
Results
We did not find a statistically significant association between DUP and either occupational activity (OR = 1.26, 95% CI 0.81–1.95) or self-perceived recovery score (β = − 0.73, 95% CI − 2.42 to 0.97). However, we found a significant negative association between DUI and self-perceived recovery score (β = − 0.52, 95% CI − 0.87 to − 0.16).
Conclusions
Our findings suggest that DUI may have a stronger influence than DUP on recovery from FEP at 10-year follow-up. This suggests the potential value in targeted interventions for people with a long DUI to increase the likelihood of achieving recovery after the first episode of psychosis.
