A total of 124 patients were included. Demographic and clinical
characteristics are presented in Table 1. The majority of
participants had a diagnosis of schizophrenia. The positive and
negative psychotic symptom level was moderately high, in
accordance with the acute setting of the inclusion. The mean
level of depressive symptoms was moderate. A CDSS sum score >6
has a specificity of 82% and a sensitivity of 85% for predicting a
major depressive episode [1]. One third of the participants had a
score >6. Three participants had attempted suicide within the last
2 weeks before admission, 10 patients had planned suicide but
made no attempt and 25 had occasional thoughts of suicide or
frequent thoughts of being better off dead. The multinominal
logistic regression analysis is presented in Table 2 (data only
shown for suicidal ideation) with the following results.
PANSS item G6 Depression Odds Ratio (OR) 12.9 (Confidence
Interval (CI) 3.0–55), p < 0.001, Clinical Drug Use OR 4.07 (1.12–
14.7), p < 0.033 and PANSS P3 Hallucinations OR 2.55 (1.2–5.5),
p < 0.016 increased the chance of suicidal ideation. Negative
symptoms OR 0.88 (0.78–0.997), p < 0.044 was associated with a
reduced chance of suicidal ideation. Suspiciousness/Persecution
did not predict suicidal ideation OR 0.82 (0.47–1.4), p < 0.480. The
odds ratio for suicidal ideation was largest for Depression, followed
by Drug use, Hallucinations and Negative symptoms.
