Background: Schizophrenia is a major mental illness with outcomes ranging from complete recovery to severe disability. Suicide is the most devastating outcome of schizophrenic illness. Around 25% of patients with schizophrenia suffer from comorbid depression. Hence, this study was conducted to find out the prevalence of suicidal ideation and its associated factors among schizophrenia patients and to determine the association between depression and suicidal ideation.
Aim: The aim of the study was to study the prevalence of depression and suicidality in schizophrenia.
Methodology: This was a cross-sectional study of 100 patients with schizophrenia carried out at the Institute of Mental Health, Chennai. Study tools used were semi-structured pro forma which included the social-demographic questionnaire, Calgary Depression Scale for Schizophrenia, and Positive and Negative syndrome scale (PANSS).
Results: About 11 and 23 participants were found to be having suicidal ideation and depression, respectively. Marital status, educational status, insight, and past suicide attempts were significantly associated with the presence of suicidal ideation with P = 0.015, 0.001, 0.019, and 0.001, respectively. PANSS score (P = 0.001) and prevalence of depression (P = 0.001) were significantly higher among patients with suicidal ideation.
Conclusion: Individuals suffering from schizophrenia are at high risk for making suicidal attempts, when accompanied by depressive symptoms and psychiatrists must intervene aggressively and early. More attention should be reserved for the high-risk group which includes those with a history of suicidal attempts and those having an insight into their illness.
