Home care workers are a priority population for ergonomic assessment and intervention, but research on caregivers' exposures to hazards is limited. The current project evaluated the reliability and validity of an ergonomic self-assessment tool called Home Care STAT (Safety Task Assessment Tool). Participants (N = 23) completed a background survey followed by 10-14 days of self-monitoring with the STAT. Results showed that the most frequent task was house cleaning, and that participants regularly performed dangerous manual client moving and transferring tasks. Researcher in-home observations of 14 workers (duration ≤ 2 h) demonstrated that workers' self-assessments were moderately reliable. Correlational and multi-level analyses of daily self-assessment data revealed that several task exposures were significantly related to daily fatigue and/or pain. Other associations have implications for Total Worker Health™; for example, daily stress was positively associated with both pain and consumption of high calorie snacks. Findings support the STAT as a reliable and potentially valid tool for measuring home care workers' exposures to physically demanding tasks.
家庭护理人员是人体工程学评估和干预的重点人群，但有关护理人员接触危害的研究有限。本研究评估了一种名为家庭护理 STAT（安全任务评估工具）的人体工程学自我评估工具的可靠性和有效性。参与者（N=23）完成了背景调查，随后使用 STAT 进行了 10-14 天的自我监测。结果表明，最常见的任务是房屋清洁，并且参与者经常进行危险的手动客户移动和转移任务。研究人员对 14 名工人（持续时间≤2 小时）进行了家访观察，结果表明工人的自我评估具有中等可靠性。对日常自我评估数据的相关和多层次分析表明，几项任务暴露与日常疲劳和/或疼痛有显著关系。其他关联对总工人健康™有影响；例如，日常压力与疼痛和高卡路里零食的摄入呈正相关。研究结果支持 STAT 作为测量家庭护理人员身体要求高的任务暴露的可靠且潜在有效的工具。
