Developing an Ethical Perspectives Scale.

Many theories hold that ethical perspectives inform moral judgments, but few such theories have corresponding individual difference scales. The present research aimed to develop an Ethical Perspectives Scale (EPS) reflecting specifically the five-perspective Markkula framework: utilitarianism; rights; fairness/justice; common good; and virtue. The authors wrote and progressively revised five sets of three items, each set intended to represent one and only one Markkula perspective, before obtaining responses from the present convenience sample (n = 621; 463 female, 157 male, 1 unspecified; Mage = 19.13, SD = 1.44) of university students. Kaiser-Meyer-Olkin (KMO = 0.867) and Bartlett's sphericity tests (χ2 = 3211.5, p < .001) showed that the data were suitable for factor analysis. An EFA with Direct Oblimin rotation yielded a five-factor structure corresponding to the five Markkula perspectives. A CFA yielded satisfactory indices of fit (χ2(80) = 92.81, p = .155, CFI = 0.991, TLI = 0.989, SRMR = 0.039, RMSEA = 0.023, HI90 ≤ .001, and LO90 = 0.041). The five subscales displayed satisfactory internal consistency (M subscale α = .76). Responses from a separate student sample (n = 148) yielded satisfactory three-week test-retest reliability (M subscale r = .72). EPS sub-scales significantly predicted evaluations of contemporary moral dilemma decisions that involved drug legalization, free speech, and pandemic restrictions. The results were interpreted as promising first steps toward an EPS useful for future research and application.
