The aim of the study was to investigate test-retest reliability and construct validity of the World Mental Health Japan (WMHJ) version of World Health Organization Health and Performance Questionnaire (WHO-HPQ) short version according the COSMIN standard. We conducted two consecutive surveys of 102 full-time employees recruited through an Internet survey company in Japan, with a two-week interval in 2018. We calculated Pearson's correlation (r) of measures of the WHO-HPQ with other presenteeism scales (Stanford Presenteeism Scale, Work Functioning Impairment Scale, and perceived relative presenteeism), health and psychosocial job conditions. We tested the test-retest reliability (intraclass correlation, ICC) among those who reported no change of job performance during the follow-up. Among 92 (90%) respondents, the absolute presenteeism significantly correlated with WFun and perceived relative presenteeism (r=-0.341 and -0.343, respectively, p=0.001) and psychological distress (r=-0.247, p=0.018). The absolute/relative absenteeism did not significantly correlate with the other covariates. The test-retest reliability over a two-week period was high for the WHO-HPQ absolute presenteeism (ICC, 0.73), while those for absolute/relative absenteeism measures were moderate. The study found an adequate level of test-retest reliability, but limited support for the construct validity of the absolute presenteeism measure of the WMHJ version of the WHO-HPQ. Further research is needed to investigate the construct validity of the WHO-HPQ measures in a larger sample.
本研究旨在根据 COSMIN 标准,调查世界心理健康日本(WMHJ)版世界卫生组织健康和绩效问卷(WHO-HPQ)短版的重测信度和结构效度。我们于 2018 年连续两次对通过日本互联网调查公司招募的 102 名全职员工进行了调查,两次调查间隔两周。我们计算了 WHO-HPQ 与其他出勤表现量表(斯坦福出勤表现量表、工作功能障碍量表和感知相对出勤表现)、健康和心理社会工作条件之间的测量指标的 Pearson 相关系数(r)。我们测试了在随访期间报告工作表现没有变化的人群的重测信度(组内相关系数,ICC)。在 92 名(90%)受访者中,绝对出勤表现与 WFun 和感知相对出勤表现呈显著负相关(r=-0.341 和 -0.343,分别为 p=0.001)和心理困扰(r=-0.247,p=0.018)。绝对/相对缺勤与其他协变量无显著相关性。在两周的时间内,WHO-HPQ 绝对出勤表现的重测信度较高(ICC,0.73),而绝对/相对缺勤表现的重测信度则适中。该研究发现,在较大样本中,WHO-HPQ 绝对出勤表现的重测信度水平适中,但对其结构效度的支持有限。需要进一步研究以调查 WHO-HPQ 测量在更大样本中的结构效度。
