背景：事实证明，未参加心理社会研究的人死亡率较高，并且对心理社会问卷的部分答复者和完全答复者的死亡率有所不同。然而，将调查响应状态与完成自杀直接联系起来的信息非常少。方法：研究人群由日本公共卫生中心前瞻性研究的参与者组成。我们的分析包括 99,439 名返回 10 年随访调查问卷的受试者和 31 754 名未返回调查问卷的个体。通过 Cox 回归模型估计根据反应状态自杀死亡的风险。结果：在 1 128 831 人年的随访期间，共有 358 人自杀（平均随访时间：8.6 年）。在返还问卷的人中，完全答复者占 53.9%，部分不答复者占 42.8%，完全不答复者占 3.3%。对于整个调查问卷，完全无反应者[风险比 (HR) = 1.84，95% 置信区间 (CI)，0.51，6.64] 和部分无反应者（HR = 1.36，95% CI，0.999，1.84）自杀风险均增加。调整变量解释了完全无反应者约 40% 的风险，但没有解释部分无反应者自杀风险的增加。对于应对分量表部分无反应者（HR = 1.36，95% CI，1.01，1.85）和对睡眠问题完全无反应者（HR = 2.07，95% CI，1.03，4.16），自杀死亡的风险显着增加。结论：与完全缓解者相比，部分和完全无缓解者的自杀风险增加。因此，在纵向研究中解释与心理社会问卷相关的数据时，应考虑不止一种无反应者类别。
Background: Non-participants to psychosocial studies have been shown to have higher mortality, and mortality differs between partial and complete responders to psychosocial questionnaires. Yet, there is very little information available directly linking survey response status with completing suicide. Methods: The study population consisted of the participants of the Japanese Public Health Center-based prospective study. Ninety-nine thousand four hundred thirty-nine subjects who returned the 10-year follow-up questionnaire and 31 754 individuals who did not return the questionnaire were included in our analyses. The risk of dying by suicide according to response status was estimated by Cox regression models. Results: There were 358 suicides during 1 128 831 person-years of follow-up (mean follow-up time: 8.6 years). Of those who returned the questionnaire, 53.9% were full responders, 42.8% were partial non-responders, and 3.3% were complete non-responders. The risk of suicide was increased for both complete non-responders [hazard ratio (HR) = 1.84, 95% confidence interval (CI), 0.51, 6.64] and partial non-responders (HR = 1.36, 95% CI, 0.999, 1.84) to the questionnaire as a whole. The adjusting variables explained around 40% of the risk for complete non-responders whereas they did not explain the increased risk of suicide for partial non-responders. The risk of dying by suicide was significantly increased for partial nonresponders to the subscale on coping (HR = 1.36, 95% CI, 1.01, 1.85) and for complete non-responders to questions on sleep (HR = 2.07, 95% CI, 1.03, 4.16). Conclusions: Partial and complete non-responders have increased suicide risk compared with full responders. More than one non-responder category should therefore be considered when interpreting data pertaining to psychosocial questionnaires in longitudinal studies.
