背景在回答自我报告的抑郁症筛查问卷，项目无应答，这是指没有答案的具体问题，是有问题的。本研究的目的为：（1）探讨自填式老年忧郁筛检问卷中无回答者的特徴（15项老年抑郁量表; GDS-15）与完全回答的受访者相比，以及（2）比较使用两种方法计算的阳性抑郁症筛查率：排除项目无应答的受访者（完整的案例分析; CCA），并估计乘以平均得分有效的答复的GDS-15项目的总数与项目non-respons.MethodsThis是一个横断面研究进行了2010年至2012年。4794老年受试者（65岁及以上）生活在一个城镇，在日本2836社区居住的老年人（59.2%）被列入analysis.ResultsItem无反应观察25.0%的受访者。项目无反应的受访者有更高的比例抑郁症和精神和身体问题。患有抑郁症（估计GDS-15评分≥6）和自杀意念的受访者在GDS-15上的项目无应答风险均高出1.6倍。积极的抑郁症筛查率GDS-15 CCA为16.5%，相比18.9%，当计算出的估计GDS-15 score.LimitationsOur调查是在一个农村地区进行，只针对老年人。在计算老年人抑郁症筛查阳性率时，排除项目无应答的受试者会导致该比率被低估。
BackgroundIn responses to self-reported depression screening questionnaires, item non-response, which refers to the absence of answers to specific questions, is problematic. The objective of this study were (1) to clarify the features of respondents with item non-response on a self-reported elderly depression screening questionnaire (15-item geriatric depression scale; GDS-15) as compared to respondents with full responses, and (2) to compare positive depression screening rates calculated using two methods: excluding respondents with item non-response (complete case analysis; CCA) and estimating by multiplying mean scores from valid responses by the total number of GDS-15 items for respondents with item non-response.MethodsThis was a cross-sectional study conducted from 2010 to 2012. Of 4794 elderly subjects (65 years and older) living in one town in Japan 2836 community-dwelling elderly people (59.2%) were included in the analysis.ResultsItem non-response was observed in 25.0% of respondents. Respondents with item non-response had a higher rate of depression and mental and physical problems. Respondents with depression (estimated GDS-15 score ≥6) and suicidal ideation both had a 1.6-times higher risk of item non-response on the GDS-15. The positive depression screening rate on GDS-15 by CCA was 16.5%, compared with 18.9% when calculated by the estimated GDS-15 score.LimitationsOur survey was conducted in one rural area and targeted only elderly people.ConclusionThe incidence of item non-response among community-dwelling elderly people was associated with depression of the respondent. Excluding subjects with item non-response when calculating positive depression screening rates in elderly individuals causes the rate to be underestimated.
