Abstract

Context: Despite the heightened risk of suicide in cancer patients, effective tools identifying those at risk remain limited.

Objectives: This study validates the multi-dimensional assessment of suicide risk in chronic illness (MASC-20) for cancer patients and examine the psychometric properties of its short-form (MASC-8).

Methods: A total of 298 patients with cancer from four teaching hospitals in South Korea completed an on-site survey, including the MASC-20, the schedule of attitudes toward hastened death-abbreviated version, Attitudes toward end-of-life interventions (e.g., euthanasia, and physician-assisted suicide), and the Hospital Anxiety and Depression scale.

Results: The MASC-20 showed excellent reliability (α=.93), and exploratory structural equation modeling confirmed its four-factor structure (physical distress, psychological distress, social distress and suicidal behavior) with acceptable model fit (CFI=.947, RMSEA=.069). A higher-order factor correlated strongly with psychological (.98) and social distress (.91). The MASC-8 retained good reliability (α=.84) and demonstrated known group validity, differentiating clinical depression/anxiety. It also showed incremental validity, explaining additional variance in desire for hastened death (ΔR²=.10, P<.001). Using a cutoff score of 6, the MASC-8 showed good sensitivity (81.8%) and specificity (73.3%; AUC=.84), performing comparably to the MASC-20.

Conclusions: The MASC-20 is a valid measure of distress and suicidal behavior in patients with cancer. The MASC-8 maintains acceptable psychometric properties, offering a brief yet effective tool for suicide risk assessment in oncology settings.

MASC-20的验证和一种评估癌症患者自杀风险的简短表格的开发。
背景:尽管癌症患者的自杀风险增加,但识别这些风险的有效工具仍然有限。目的:本研究对癌症患者慢性疾病自杀风险多维度评估(MASC-20)进行了验证,并对其短表(MASC-8)的心理测量特征进行了检验。方法:对韩国四所教学医院的298例癌症患者进行现场调查,包括MASC-20、对加速死亡的态度表(简写版)、对临终干预(如安乐死、医生协助自杀)的态度以及医院焦虑和抑郁量表。结果:MASC-20具有良好的信度(α = .93),探索性结构方程模型证实了其四因素结构(身体困扰、心理困扰、社会困扰和自杀行为)具有良好的模型拟合(CFI = )。947年,RMSEA = .069)。高阶因子与心理困扰(.98)和社会困扰(.91)密切相关。MASC-8保持了良好的信度(α = .84),并表现出已知的组效度,用于区分临床抑郁/焦虑。它还显示了增量效度,解释了加速死亡欲望的额外方差(ΔR² = )。10, p < 0.001)。截止评分为6分,MASC-8具有良好的敏感性(81.8%)和特异性(73.3%);AUC = .84),性能与MASC-20相当。结论:MASC-20是评估癌症患者痛苦和自杀行为的有效方法。MASC-8保持了可接受的心理测量特性,为肿瘤环境中的自杀风险评估提供了一个简短而有效的工具。
