- The trend toward assortative mating is the rule in Western societies for a large series of factors. The case for personality variables is however not clear, since weak and even negative relationships have been found in correlation analyses between spouses. The present study compared the profiles of members from 145 stable couples living together for more than 5 years, and representative of the Belgian population. Personality measurements were performed using Cloninger’s Temperament and Character Inventory (TCI), in order to: 1) determine whether the subject’s TCI predicts the partner’s profile; 2) determine whether modeling has an important influence between the partners; 3) describe the behavior of personalities with extreme traits; 4) measure whether personalities with extreme traits would favor complementarity over homogamy. In all dimensions but Harm Avoidance and its sub-dimensions, positive associations were found between the partners, indicating a trend toward assortative mating. These differences were significant for Novelty Seeking, Reward Dependence, Persistence and Cooperativeness. Trends were observed in Self-Directedness and Self-Transcendence. Subjects with extreme personality traits were not shown to favor complementarity over assortative mating. Homogamy was thus confirmed here for a series of personality traits, independently of the TCI Temperament or Character classification and on the subjects position in the distribution.

- As personality may predispose, precipitate or perpetuate substance abuse and/or dependence, and as it is considered to remain stable across the years in a given subject, potential links with the drug of choice may help screen future patients before drug consumption. The present study compared three groups: 42 patients with heroin dependence (mean age: 31.2; standard deviation (SD): 5.5; 10 females), 37 patients with alcohol dependence (mean age 44.2; SD: 9.1; 9 females) and 83 subjects from a random population sample (mean age: 38.8; SD: 6.9; 20 females). Personality was measured by Cloninger's Temperament and Character Inventory (TCI). Pillai's MANCOVA with age as a covariate and gender as a cofactor was highly significant. Univariate ANOVA analyses using TCI dimensions as dependent variable showed most variables to vary in parallel for the two patient groups in comparison with controls. Post-hoc tests showed heroin patients to score higher in Novelty-Seeking and Self-Directedness than alcohol patients. Sub-dimensions Exploratory Excitability, Fear of the Uncertain, Responsibility, Congruent Second Nature and Transpersonal Identification were also significantly different in the two patient samples. Logistic regression showed Exploratory Excitability to segregate up to 76% of heroin patients from alcohol patients. In conclusion, personality profiles were linked to some preferential choice of drug and personality screening might be tested in preventive strategies.
