Abstract
Methods
In this analysis, a structural equation model approach for longitudinal data was applied to identify the direction of statistical
relationships between hours worked, clinical status and days in psychiatric hospital in 312 persons with schizophrenia who
participated in a multi-centre randomised controlled trial comparing the effectiveness of Individual Placement and Support
(IPS) with conventional vocational services in six study settings across Europe. Data were analysed by an autoregressive cross-lagged
effects model, an autoregressive cross-lagged model with random intercepts and an autoregressive latent trajectory model.

Results
Comparison of model fit parameters suggested the autoregressive cross-lagged effects model to be the best approach for the
given data structure. All models indicated that patients who received an IPS intervention spent more hours in competitive
employment and, due to indirect positive effects of employment on clinical status, spent fewer days in psychiatric hospitals
than patients who received conventional vocational training.
