Modèle de la compatibilité fondé sur l’attachement et la personnalité chez des couples en détresse
The first goal of this thesis is to propose a new model of compatibility. Partner’s compatibility is conceptualized from two attachment dimensions (avoidance and anxiety) as well as personality trait (neurotism). The second goal was to test this model on a sample of couples seeking marital therapy. A critical literature review on the role of compatibility in the understanding of couples’ dynamics is completed, underlining the relevance of improving this concept’s definition by taking attachment and neurotism into account. Methodological and statistical issues to consider are also discussed.  To evaluate the predictive validity of the model, 365 couples completed the Dyadic adjustment scale (Spanier, 1976), the NEO-FFI (Costa & McCrae, 1992) and the Experiences in close relationships questionnaire (Brennan, Clark, & Shaver, 1998) at intake. The association between personality, attachment and marital satisfaction is first examined with the Actor-Partner Interdependence Model (Kashy & Snyder, 1995). Results show that attachment avoidance is negatively associated with marital satisfaction for spouses themselves as well as for their partners. Analysis of similarities and differences is then performed, revealing that differences between partners on the combination of avoidance and neurotism are correlated with marital insatisfaction. To examine the patterns of natural groupings between partners in the sample, clusters analyses were conducted. Seven different types of couples exhibiting significant differences in their marital satisfaction were found. Three main groups of couples were identified within these types, the first one regrouping mostly satisfied couples, a second one including very dissatisfied partners and a last one presenting a difference between the man’s and the women’s satisfaction. These results could be considered as provinding preliminary confirmation of our compatibility model based on attachment and neurotism, but these propositions must be validated.  Some elements of the present findings suggest that it is the combination of attachment anxiety, avoidance and neurotism between partners that is linked to severity of marital distress. However, many challenges, conceptual, theoretical, as well as methodological, are then discussed and future scientific contributions are proposed in order to consolidate the conceptual base of compatibility.
