| Researchers studying social intelligence have often failed to find convergent validity among self-report and skill-based measures of social-intelligence-related constructs such as affective sensitivity. In this study, a Multitrait-Multimethod (MTMM) approach was used to examine the role of method bias in measuring constructs related to social intelligence. The Multitrait-Multimethod matrix consisted of three trait factors (affective sensitivity, academic intelligence, and social intelligence) and three method factors (self-report, others' ratings, and skill/behavioral). A group of 30 pairs of friends participated in the study (N = 60). Convergence, divergence, and method bias was examined using both Confirmatory Factor Analysis (CFA), and the original Campbell and Fiske (1959) criteria. The method bias found for self-report measures is discussed in terms of potential costs and benefits. |
