To develop a tool to assess the team leadership skills of internal medicine residents.
A 27-item pilot instrument developed by two authors was distributed to interns on ward and intensive care unit teams at the end of rotations from a single institution's internal medicine residency program. These items were factor analyzed and reduced to a seven-item resident leadership scale (RLS). Validity of the instrument was assessed by comparing the rating on the RLS to scores on a validated measure of teaching skills provided at the same time and by the program director's global rating of team leadership skill for each resident at the completion of data collection.
The three principal components from the factor analysis explained 82 percent of the variance. By introspection we reduced the scale to the final 7-item RLS that had a Cronbach alpha reliability estimate of 0.95. 490 ratings on 134 individual residents were available for analysis. The RLS scores correlated highly with both the validated measure of teaching skill and the program director's ratings.
The RLS has robust psychometric properties. It may provide a useful tool for a broader assessment of trainee skill if validated in other settings.
开发一种工具来评估内科住院医师的团队领导技能。
由两位作者开发的一份包含27个条目的初步工具，在一所机构内科住院医师培训项目轮转结束时，分发给病房和重症监护室团队的实习医生。对这些条目进行因子分析，并缩减为一个包含七个条目的住院医师领导能力量表（RLS）。通过将RLS评分与同时提供的经过验证的教学技能测量得分进行比较，以及在数据收集完成时由项目主任对每位住院医师的团队领导技能进行整体评分，来评估该工具的有效性。
因子分析的三个主要成分解释了82%的方差。通过自省，我们将量表缩减为最终的7条目RLS，其Cronbach α信度估计值为0.95。有134名个体住院医师的490份评分可供分析。RLS得分与经过验证的教学技能测量得分以及项目主任的评分都高度相关。
RLS具有稳健的心理测量特性。如果在其他环境中得到验证，它可能为更广泛地评估学员技能提供一个有用的工具。
