The relationships between employment, clinical status, and psychiatric hospitalisation in patients with schizophrenia receiving either IPS or a conventional vocational rehabilitation programme


Kilian, Reinhold; Lauber, Christoph; Kalkan, Rana; Dorn, Wulf; Rössler, Wulf; Wiersma, Durk; Buschbach, Jooske T; Fioritti, Angelo; Tomov, Toma; Catty, Jocelyn; Burns, Tom; Becker, Thomas (2012). The relationships between employment, clinical status, and psychiatric hospitalisation in patients with schizophrenia receiving either IPS or a conventional vocational rehabilitation programme. Social Psychiatry and Psychiatric Epidemiology, 47(9):1381-1389.

Abstract

PURPOSE: Positive relationships between employment and clinical status have been found in several studies. However, an unequivocal interpretation of these relationships is difficult on the basis of common statistical methods.
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.
CONCLUSIONS: Results support the hypothesis that the IPS intervention has positive effects not only on vocational but also on clinical outcomes in patients with schizophrenia.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
