Toward a motivational model of couple happiness.

Abstract

The present study had two major objectives. The first was to investigate the validity of a motivational model of couple happiness based on self-determination theory. The second objective was to test the postulated simplex structure and the generalizability of the 6 forms of motivation proposed by this theory. Both members of 63 couples individually completed the Couple Motivation Questionnaire as well as measures of perceived couples' adaptive behaviors and of dyadic happiness. Results revealed that the proposed model of couple happiness was supported through significant path analyses explaining 61% and 55% of the variance of men's and women's relationship happiness, respectively. Empirical support was also provided for the postulated simplex structure. Results highlight the importance ofautonomy-driven processes as opposed to controlling and amotivated processes in the development and maintenance of the quality of couples' relationships.
