Abstract

Generalizability Theory (GT) analyses of different designs were conducted to assess the score reliability from the personality traits test concerning dominance, influence, steadiness, and compliance (DISC). Responses from 898 participants were analyzed in a univariate two-facet design with items (i) nested within trait scale (h), i : h, crossed with the object of measurement person (p), p × (i : h), and the counterpart multivariate design p• × i◦. Following the G-study, generalizability and dependability coefficients were used in D-study to identify the optimal facet conditions for the desired level of reliability. Results suggested that the dominance scale contributed the most variation in the DISC personality test, and the reached .8 score reliability threshold demonstrated the advantages of employing GT analyses.
