Suicidal behaviour after first-episode psychosis: results from a 1-year longitudinal study in Portugal

Table 3 Multivariate logistic regression analysis for predictors of baseline and 12-month suicidal behaviour in first-episode psychosis patients^a,b

Variables in the equation	B	SE	Wald	df	p value	OR	95% CI
Baseline
Depression baseline	1.087	0.463	5.514	1	0.019	2.96	1.20–7.34
History of suicide behaviour	1.237	0.456	7.343	1	0.007	3.44	1.41–8.43
Constant	− 0.153	0.367	0.175	1	0.676	0.86
Final model: Nagelkerke R² = 0.185, χ² = 15.850, p < 0.0001 Hosmer and Lemeshow test supported the goodness of fit of the model (χ² = 0.006, df = 2, p = 0.997)
12-month follow-up
History of suicide behaviour	2.849	1.172	5.910	1	0.015	17.27	1.74–171.65
Total cholesterol baseline	− 0.030	0.014	4.411	1	0.036	0.97	0.94–0.99
Constant	5.643	2.369	5.674	1	0.017	282.31
Final model: Nagelkerke R² = 0.373, χ² = 13.600, p = 0.001 Hosmer and Lemeshow test supported the goodness of fit of the model (χ² = 12.657, df = 8, p = 0.124)

^aAffective psychosis diagnosis and PANSS general were entered into stepwise logistic regression model, were excluded as predictors of baseline suicidal behaviour
^bLast month baseline suicidal behaviour were entered into stepwise logistic regression, were excluded as predictors of 12-month suicidal behaviour
