The presence of a bipolar spectrum diagnosis proved to be the highest risk factor (B = 4.33; exp(B) = 76.52; 95% confidence interval for exp(B) = 35.69-164.04; P<0.001) for the presence of aggressive behavior (χ²= 433.05; df = 5; P<0.001). The highest risk factor for the presence of moderate/superficial self-harm (χ² = 24.83; df = 2; P<0.001) was a dual diagnosis for chronic psychosis (β = 1.46; exp(B) = 4.34); 95% confidence interval for exp(B) = 1.11-16.98; P<0.001)
