Abstract
AimsTo examine whether baseline neurocognition and social cognition predict vocational outcomes over 6months in patients with first-episode psychosis (FEP) enrolled in a randomised controlled trial of Individual Placement and Support (IPS) versus treatment as usual (TAU). Methods135 FEP participants (IPS n=69; TAU n=66) completed a comprehensive neurocognitive and social cognitive battery. Principal axis factor analysis using PROMAX rotation was used to determine the underlying cognitive structure of the battery. Setwise (hierarchical) logistic and multivariate linear regressions were used to examine predictors of: (a) enrolment in education and employment; and (b) hours of employment over 6months. Neurocognition and social cognition factors were entered into the models after accounting for premorbid IQ, baseline functioning and treatment group. ResultsSix cognitive factors were extracted: (i) social cognition; (ii) information processing speed; (iii) verbal learning and memory; (iv) attention and working memory; (v) visual organisation and memory; and (vi) verbal comprehension. Enrolment in education over 6months was predicted by enrolment in education at baseline (p=.002) and poorer visual organisation and memory (p=.024). Employment over 6months was predicted by employment at baseline (p=.041) and receiving IPS (p=.020). Better visual organisation and memory predicted total hours of paid work over 6months (p<.001). ConclusionsVisual organisation and memory predicted the enrolment in education and duration of employment, after accounting for premorbid IQ, baseline functioning and treatment. Social cognition did not contribute to the prediction of vocational outcomes. Neurocognitive interventions may enhance employment duration in FEP.
