Logistic regression predicting likelihood of an inactive occupational status (cognitive and clinical factors as predictors)

	p-value	OR	95% CI
Executive functions	0.001	0.55	0.38–0.78
WAIS-III–IQ	0.196	1.04	0.98–1.10
History of psychosis	0.240	0.41	0.09–1.81
Involuntary care	0.245	2.46	0.54–11.2
Benzodiazepines	0.224	0.47	0.14–1.58
Constant	0.135	0.01

Occupational status as a dichotomized dependent variable (inactive = 1; active = 0) and five covariates, including Executive functions (composite measure) and Full Scale IQ (measured with WAIS-III). Categorical covariates are prior history of psychotic symptoms (yes = 1; no = 0), history of involuntary care (i.e. if ever sectioned under the Mental Health Act; yes = 1; no = 0), and benzodiazepines (yes = 1; no = 0). The full model significantly predicted an inactive occupational status (omnibus Chi-square = 24.11, df = 5, p < 0.001). Cox and Snell’s R² = 0.23 Nagelkerke’s R² = 0.33. The model correctly classified 78.7% of the patients (92.6% of the active patients and 42.3% of the inactive patients were correctly classified), n = 94
