背景：一些关于儿童癌症幸存者(CCS)长期适应的研究报告了非常积极的结果，而其他研究发现了显著的适应问题。这些不一致促使一些调查人员暗示，幸存者可能是有偏见的响应者，容易在自我报告措施上报告不足。本研究验证了自欺性反应偏向(SDRB)增加CCS的假设，并且SDRB与较高的生活质量(QOL)评分相关。方法107名成年癌症幸存者(平均年龄=31.85岁)完成了人口统计学调查问卷、简明12问卷(SF-12)、癌症治疗功能评定(FACT-G)和自欺欺性增强量表(SDE)(SDRB测量)。即使考虑了人口学和治疗相关变量，SDE得分与FACT-G、SF-12心理健康(但不是身体健康)得分显著相关。结论CCS表现出一种偏颇的反应方式，表明系统性倾向于否认生活质量测量上的困难。这可能会夸大幸存者关于其社会情绪功能的报告，从而使生活质量研究复杂化。了解反应偏差是如何发展的，可能有助于我们更多地了解癌症幸存者对疾病的适应，以及疾病经历对他们对生活质量的感知的影响。
Background Several studies of long-term adjustment in childhood cancer survivors (CCS) report very positive outcomes, while other studies find significant adjustment problems. These inconsistencies have prompted some investigators to suggest survivors may be biased responders, prone to underreporting on self-report measures. This study tested the hypothesis that CCS are elevated on self-deception response bias (SDRB), and that SDRB is associated with higher ratings of quality-of-life (QOL).Methods One hundred and seven adult (mean age = 31.85) survivors of childhood cancers completed a demographic questionnaire, Short Form-12 (SF-12), Functional Assessment of Cancer Therapy-General (FACT-G), and Self-Deception Enhancement scale (SDE), an SDRB measure.Results Survivors' QOL scores were similar to normative groups, but they evidenced much higher levels of response bias. SDE scores were significantly correlated with the FACT-G, and SF-12 Mental Health (but not Physical Health) scores even after accounting for demographic and treatment-related variables.Conclusions CCS show a biased response style, indicating a systematic tendency to deny difficulties on QOL measures. This may complicate QOL studies by inflating survivors' reports of their socio-emotional functioning. Understanding how response bias develops may help us learn more about cancer survivors' adaptation to illness, and the effects of the illness experience on their perceptions of QOL.
