Measuring assimilative and accommodative resources in young adults: Development and initial validation of suitable scales

Abstract

New scales measuring assimilation and accommodation (cf. the dual-process framework) were developed for use with young adults. Experts reviewed 41 items which were then administered to 235 young adults (Mage = 22; 72% female). Exploratory factor analyses reduced these to two 10-item scales, which demonstrated high internal consistency (α > .90). Confirmatory factor analysis using a second sample (N = 236, Mage = 22; 77% female) confirmed the proposed structure. Construct validity was supported by finding correlations in the expected directions with measures of goal engagement, disengagement, re-engagement, and life satisfaction. The new scales will allow assimilative and accommodative resources to be assessed in young people.
