^aThe data in the columns presents the odds ratios for participants with SA + NSSH or SA only having the given characteristic compared to participants with NoSA (reference category). Levels of statistical significance: ns = not significant * = p < 0.05, ** = p < 0.01, *** = p < 0.001.
^bVariables entered in Model 1: Age of first psychotic symptoms, Depressive episode, First symptoms before the age of 18, DUP > 52 weeks, Gender.
^cVariables entered in Model 2: step 1 + Current medication, GAF F, CDSS (current depression), PANSS G14 (Impulsive aggression), InterSePT 5 (Current suicidality). Step 2 Model chi-square = 311.084, df = 10, p < .001. The model as a whole explained between 31% (Cox and Snell R²) and 37% (Nagelkerke R²) of the variance and correctly identified 71% of the cases. n = 233 in the final model.
