The Millon Clinical Multiaxial Inventory, 4th edition (MCMI-IV; Millon et al., 2015) is a reliable and valid personality assessment based on Theodore Millon’s biosocial learning theory of personality. Millon’s theory evolved to include 15 personality constructs that vary in adaptive and maladaptive response patterns. In his most recent book (Millon, 2011), he presented hypotheses about biological and environmental factors that contribute to development of each personality construct. Many of these hypotheses specify particular adversities in childhood that differentially contribute to each construct. This study is the first to evaluate Millon’s hypotheses about how childhood adversities may contribute to development of personality traits evaluated by the MCMI-IV.
