Patients with schizophrenia tend to have high rates of suicidal ideation (SI), which consists of thoughts of self-destruction, which increase the risk of self-extermination.

To determine the prevalence of SI and investigate associated factors in a sample of patients with schizophrenia.

Descriptive and cross-sectional study, in which 49 patients with the condition were selected by convenience, treated at the Psychosis Outpatient Clinic of the Base Hospital of São José do Rio Preto/SP, between August/2021 and March/2022. The following were applied: 1) Sociodemographic Questionnaire, 2) Suicide Ideation Section of the Columbia Suicide Risk Assessment Scale (SISC-SSRS), 3) Suicide Risk Questionnaire from the Mini International Neuropsychiatric Interview (SRQ-MINI). Data were analyzed quantitatively (descriptive statistics and non-parametric tests; p<0.05). The study was approved by the local Research Ethics Committee.

The age of the participants ranged from 17 to 72 years (mean=45.8 ±14.02), most were male (n=34;69.4%), had not completed elementary school (n=25; 51%), did not have a paid job (n=41; 83.7%) and had a family income of up to three minimum wages (n=23;46.9%). 40.8% (n=20) reported at least one suicide attempt. According to the SISC-SSRS, in the last month: 22.9% (n=11) wished they were dead; 18.8% (n=9) thought about killing themselves; 12.5% (n=6) considered how they could perform the act; 10.4% (n=5) had intention and active planning; and 10.4 (n=5) persisted for the purpose of execution. The mean of affirmative answers was equal to 0.75 (±1.55). In turn, in the SRQ-MINI, 79.6% (n=39) had a score indicating low risk for suicide, 18.4% (n=9) high risk and 2% (n=1) moderate risk. The overall mean was 5.77 (±10.31), which indicates a moderate risk for suicide. There was a non-significant negative correlation between the risk of suicide and the factors of education (r= -0.20; p=0.15) and family income (r= -0.21; p=0.13). There was a significant positive correlation (r=0.81; p=0.0001) between the SISC-SSRS and SRQ-MINI, which indicates that despite the adapted use of the instrument, there is consistency and reliability in the results.

The sample showed low rates of active SI and variation between low and moderate risk for suicide. SI should be asked to patients with schizophrenia, with a view to preventing suicidal behavior.
