Schizophrenic patients are at high risk for suicide. Most of the clinical features of the illness which have been associated with suicide remain speculative. This study provides an empirical test of hypothetical risk factors from the literature. Results indicate that schizophrenic patients who kill themselves have high internalized standards of performance which are often congruent with past educational attainments. They are also realistically aware of the effects of their illness, feel inadequate in relation to their goals, and fear further mental disintegration. Their affect is depressed, and they express hopelessness about the future. Suicidal ideation and explicit suicide threats often precede death. These results can be used to assess suicide risk among schizophrenic patients.
精神分裂症患者有很高的自杀风险。该疾病与自杀相关的大多数临床特征仍属推测。本研究对文献中的假设风险因素进行了实证检验。结果表明，自杀的精神分裂症患者具有较高的内化表现标准，这通常与过去的教育成就相符。他们也切实意识到自己疾病的影响，觉得自己在实现目标方面能力不足，并担心精神进一步衰退。他们情绪低落，对未来表示绝望。自杀念头和明确的自杀威胁往往先于死亡出现。这些结果可用于评估精神分裂症患者的自杀风险。
