While an important predictor of future research involvement, formal assessment of the quality of the research training environment in pharmacy residency training has not been examined. The objective of this study was to evaluate the psychometric properties of a modified version of the shortened form of the revised Research Training Environment Scale (RTES-R-S) in pharmacy residents.
The original wording of the 18 items from RTES-R-S was modified to reflect pharmacy residency training. Data were collected as part of a larger study involving a random sample of pharmacy residents in the United States during the 2016-2017 residency year. Internal consistency was assessed with Cronbach's α. Confirmatory factor analysis was used to assess the fit of the factor structures examined previously during the original RTES-R-S development.
Based on confirmatory factor analysis, the preferred model proposed a single, second-order factor predicting nine factors reflecting Gelso's previously described ingredients of the research training environment. This model had acceptable fit indices and was statistically better than models without second-order factors. Cronbach's α for the global scale was 0.86, with the two subscales >0.7.
Minor rewording of an existing instrument to measure residents' perceptions of the quality of the research training environment demonstrated acceptable internal consistency. The factor structure of the recommended use proposed by the original developers of the RTES-R-S was supported in this sample of pharmacy residents. Continued work with additional samples is needed to generate additional validity evidence supporting the use of this tool in pharmacy residents.
虽然正式评估药学住院医师培训中研究培训环境的质量是未来研究参与度的一个重要预测指标，但尚未对此进行过研究。本研究的目的是评估修订版研究培训环境量表简表（RTES-R-S）的修改版在药学住院医师中的心理测量特性。
对RTES-R-S中18个条目的原始措辞进行修改，以反映药学住院医师培训情况。数据收集是作为一项更大规模研究的一部分，该研究涉及2016 - 2017住院医师培训年度美国药学住院医师的随机样本。使用Cronbach's α评估内部一致性。验证性因素分析用于评估在RTES-R-S原始开发过程中先前检查过的因素结构的拟合度。
基于验证性因素分析，首选模型提出了一个单一的二阶因素，该因素预测九个因素，反映了Gelso先前描述的研究培训环境要素。该模型具有可接受的拟合指数，并且在统计学上优于没有二阶因素的模型。全球量表的Cronbach's α为0.86，两个子量表>0.7。
对现有工具进行轻微措辞修改以测量住院医师对研究培训环境质量的看法，显示出可接受的内部一致性。在该药学住院医师样本中，支持了RTES-R-S原始开发者建议使用的因素结构。需要对更多样本继续开展工作，以生成更多有效性证据，支持在药学住院医师中使用该工具。
