Background: The Global Assessment of Functioning (GAF) scale is a measure widely used to assess the outcome of patients with schizophrenia. However, little is known about the importance of clinical and psychosocial variables in determining its final score. The aim of this paper is to identify which factors predict GAF scores of patients with schizophrenia and their variability in 5 different European settings. Method: A representative sample of 404 patients with schizophrenia was assessed with the GAF. A multiple regression analysis was performed to identify predictors of the GAF scores. Results: Clinical factors are the main determinants of GAF score. However, the analysis also showed that social and functioning factors were also significantly associated with GAF scores. Finally, the study showed the presence of intercenter differences in the factors, mainly in social functioning. Conclusions: The GAF is a useful and easy-to-apply measure of global functioning, independent of cross-cultural differences. Clinical factors are the main determinants of its score, although social functioning variables also have a lesser effect. © 2005 Elsevier Inc. All rights reserved.

Abstract
Background: The Global Assessment of Functioning (GAF) scale is a measure widely used to assess the outcome of patients with schizophrenia. However, little is known about the importance of clinical and psychosocial variables in determining its final score. The aim of this paper is to identify which factors predict GAF scores of patients with schizophrenia and their variability in 5 different European settings. Method: A representative sample of 404 patients with schizophrenia was assessed with the GAF. A multiple regression analysis was performed to identify predictors of the GAF scores. Results: Clinical factors are the main determinants of GAF score. However, the analysis also showed that social and functioning factors were also significantly associated with GAF scores. Finally, the study showed the presence of intercenter differences in the factors, mainly in social functioning. Conclusions: The GAF is a useful and easy-to-apply measure of global functioning, independent of cross-cultural differences. Clinical factors are the main determinants of its score, although social functioning variables also have a lesser effect. © 2005 Elsevier Inc. All rights reserved.
