Purpose: The shorter life expectancy and increased risk of suicide in patients with schizophrenia have been well documented. However, study outcomes on suicidality in this special population have been few to date. This study investigated the prevalence and factors associated with suicidal ideation in a population of institutionalized patients with schizophrenia.
Methods: Two hundred fifty-six patients with schizophrenia between the age of 18 and 65 years were randomly recruited. This cross-sectional study utilised the Calgary Depression Scale for Schizophrenia (CDSS), the Positive and Negative Syndrome Scale (PANSS) and the Psychotic Symptom Rating Scale (PSYRATS-AH). Univariate analysis was performed using an independent t-test or chi-square test, followed by binary logistic regression to determine the factors associated with increased suicidal risks.
Results: The socio-demographic factors associated with suicidal ideation included level of education (p=0.039); secondary-level education (OR=5.76, 95% CI:1.49, 22.34, p=0.011) and tertiary-level education (OR=9.30, 95% CI: 1.80, 48.12, p=0.008) posed a greater risk. A history of attempted suicide (OR=2.09, 95% CI: 1.01, 4.36, p=0.049) and the presence of co-morbid physical illnesses (OR=2.07, 95% CI: 1.02, 4.21, p=0.044) were also found to be associated with a suicidal ideation. Other significant factors associated with suicidal thoughts were concurrent depression (OR=9.68, 95% CI: 3.74, 25.05, p< 0.001) and a higher PSYRATS score in emotional characteristics of auditory hallucinations (OR=1.13, 95% CI: 1.06, 1.21, p< 0.001).
Conclusion: Suicide in schizophrenia appears to be more closely associated with certain socio-demographic factors and affective symptoms. Appropriate screening and treatment addressing these challenges must be emphasized if suicidal thoughts and actions are to be reduced.

住院精神分裂症患者自杀意念的患病率和相关因素
目的:精神分裂症患者的预期寿命缩短和自杀风险增加已得到充分证明。然而,迄今为止,关于这一特殊人群自杀的研究结果很少。本研究调查了住院精神分裂症患者群体中与自杀意念相关的患病率和因素。
方法:随机招募18-65岁的精神分裂症患者256例。这项横断面研究使用了卡尔加里精神分裂症抑郁量表 (CDSS)、阳性和阴性综合症量表 (PANSS) 和精神病症状评定量表 (PSYRATS-AH)。使用独立的t进行单变量分析检验或卡方检验,然后进行二元逻辑回归以确定与自杀风险增加相关的因素。
结果:与自杀意念相关的社会人口因素包括教育水平(p = 0.039);中等教育(OR=5.76, 95% CI:1.49, 22.34, p =0.011)和高等教育(OR=9.30, 95% CI: 1.80, 48.12, p =0.008)风险更大。有自杀未遂史 (OR=2.09, 95% CI: 1.01, 4.36, p =0.049) 和合并躯体疾病 (OR=2.07, 95% CI: 1.02, 4.21, p= 0.044)也被发现与自杀意念有关。与自杀念头相关的其他重要因素包括并发抑郁症(OR=9.68, 95% CI: 3.74, 25.05, p < 0.001)和幻听情绪特征中较高的 PSYRATS 评分(OR=1.13, 95% CI: 1.06, 1.21 , p < 0.001)。
结论:精神分裂症患者的自杀似乎与某些社会人口因素和情感症状密切相关。如果要减少自杀念头和行动,就必须强调应对这些挑战的适当筛查和治疗。
