Questionnaires are valuable for population surveys of mental health. Different survey instruments may however give different results. The present study compares two mental health instruments, the Major Depression Inventory (MDI) and the Mental Health Inventory (MHI-5), in regard to their prediction of long-term sickness absence.
Questionnaire data was collected from N = 4153 Danish employees. The questionnaire included the MDI and the MHI-5. The information of long-term sickness absence was obtained from a register. We used Cox regression to calculate covariance adjusted hazard ratios for long-term sickness absence for both measures.
Both the MDI and the MHI-5 had a highly significant prediction of long-term sickness absence. A one standard deviation change in score was associated with an increased risk of long-term sickness absence of 27% for the MDI and 37% for the MHI-5. When both measures were included in the same analysis, the MHI-5 performed best.
In general population surveys, the MHI-5 is a better predictor of long-term sickness absence than the MDI.
问卷在精神健康的人群调查中很有价值。然而，不同的调查工具可能会产生不同的结果。本研究比较了两种心理健康工具，即 Major Depression Inventory（MDI）和 Mental Health Inventory（MHI-5），以评估它们对长期病假的预测能力。
从丹麦 4153 名员工中收集了问卷调查数据。问卷包括 MDI 和 MHI-5。长期病假的信息从登记处获得。我们使用 Cox 回归计算了两个指标的长期病假的调整后的风险比。
MDI 和 MHI-5 对长期病假都有高度显著的预测能力。评分的一个标准差变化与 MDI 的长期病假风险增加 27%和 MHI-5 的长期病假风险增加 37%相关。当两个指标都包含在同一个分析中时，MHI-5 的表现最好。
在一般人群调查中，MHI-5 是长期病假的更好预测指标，优于 MDI。
