Developing and Validating the Claremont Evaluative Thinking Scale
Main Article Content
Abstract
Evaluation scholars and practitioners have argued that having more people who can think evaluatively is “essential” for successful evaluation practice, organizational improvement, and even healthy democracies. However, empirical evidence backing those claims is scant. Making a case for investing more resources into building people’s capacity to think evaluatively requires a better understanding of its impact and added value. We need a way to measure it. While two scales to measure evaluative thinking exist, both have shortcomings and neither has been used to build a body of evidence concerning the contributions of evaluative thinking to the evaluation field and beyond. A two-stage, mixed-methods study was conducted to create a new, reliable and valid evaluative thinking scale. Stage One identified dimensions of evaluative thinking through literature review and expert interviews. Stage Two generated and refined items to measure these dimensions, confirmed face validity through focus groups, and administered the refined items to 250 random, yet screened, participants. Factor analysis revealed six factors with strong item loadings, and a Cronbach’s alpha test confirmed reliability (α = 0.96). This study enhances our capacity to measure evaluative thinking and lays the groundwork for future research into understanding its impact more deeply.
