Items from the Reinvestment Scale were modified to create a decision-specific version of the scale. Principal components analysis of responses from 165 participants revealed one-, two-, three-, and four-factor solutions for the Decision-Specific Reinvestment Scale. Confirmatory factor analysis of responses from a second sample of 111 participants revealed that a 13-item two-factor solution showed the best fit. The first factor comprised six items referring to conscious monitoring of the process involved in making a decision, and was termed decision reinvestment. The second factor, decision rumination, comprised seven items related to focus on negative evaluations of previous poor decisions. In an initial assessment of predictive validity, Decision-Specific Reinvestment Scale scores of 59 skilled team sport players were found to be highly correlated with coaches' ratings of players' tendency to choke under pressure (r = 0.74), with high Decision-Specific Reinvestment Scale scores indicating greater susceptibility to poor decision-making under pressure. It was concluded that the Decision-Specific Reinvestment Scale highlights a performer's predisposition to engage in behaviours detrimental to performance under pressure, namely decision reinvestment and decision rumination.
项目的再投资规模进行了修改，以创建一个决策特定版本的规模。从 165 名参与者的反应的主成分分析揭示了一个，二，三，和四因素的解决方案的决策特定的再投资规模。从第二个样本的 111 名参与者的反应验证性因素分析表明，一个 13 项的双因素解决方案显示出最好的适应性。第一个因素包括六个项目，指的是对决策过程的有意识的监测，被称为决策再投资。第二个因素，决策反刍，包括七个项目与关注对以前糟糕决策的负面评价有关。在对预测有效性的初步评估中，发现 59 名熟练的团队运动运动员的决策特定再投资量表得分与教练对运动员在压力下窒息倾向的评分高度相关(r = 0.74)，高决策特定再投资量表得分表明在压力下更易出现不良决策。结论是，决策特定的再投资量表突出了一个表演者在压力下从事不利于表现的行为的倾向，即决策再投资和决策反刍。
