本研究检验了一个简短的六项工具的可靠性和有效性，该工具用于测量住院医师在门诊护理诊所就诊的特定患者所经历的心理负担。 参与这项研究的是 22 名研究生一年级至三年级的居民，他们在市中心一家私立非营利性社区医院的普通门诊诊所工作。 该仪器的 Cronbach α 系数为 0.80。 研究结果支持了关于脑力负荷的决定因素和表现后果的几种基于理论的假设。 精神负荷与疲劳呈正相关（r = 0.42，P = 0.03），与住院医师自评的患者问题经历呈负相关（r = -0.65，P < 0.001）。 住院医师的表现是通过自我评分和教职医生的评分来衡量的。 脑力负荷与自评表现呈负相关（r = -0.67，P < 0.001）。 脑力负荷与反映患者护理技术维度（医生检查、药物和手术）的医师评分的相关性为 r = -0.38 (P = 0.04)。 脑力负荷平方后，相关性为 r = -0.45 (P = 0.02)，并且该关系的形式与假设一致，是一条稍微向下倾斜的曲线。 讨论了这项研究的局限性以及进一步研究的建议。
This study examined the reliability and validity of a brief six-item instrument to measure the mental workload experienced by residents for specific patient visits to an ambulatory care clinic. Participating in the study were twenty-two residents in postgraduate years 1 through 3 who were working in the general outpatient clinic of an inner city, private, nonprofit community hospital. Cronbach's alpha coefficient for the instrument was 0.80. Findings supported several theory-based hypotheses on determinants and performance consequences of mental workload. Mental workload was positively correlated with fatigue (r = 0.42, P = 0.03) and inversely correlated with residents' self-rated experience with patients' problems (r = -0.65, P < 0.001). Residents' performance was measured through self-ratings and faculty physicians' ratings. Mental workload was inversely correlated with self-rated performance (r = -0.67, P < 0.001). The correlation of mental workload with faculty physician ratings that reflected the technical dimension of patient care (physician examination, medications, and procedures) was r = -0.38 (P = 0.04). With mental workload squared, the correlation was r = -0.45 (P = 0.02) and the form of the relationship, consistent with the hypothesis, was a slightly downward sloping curve. Limitations of this research are discussed as well as suggestions for further research.
