Sociotropy and autonomy are conceptualized as two personality dimensions that relate to an individual's vulnerability to depression. Sociotropy is characterized as an excessive investment in interpersonal relationships and autonomy is characterized as an excessive concern with personal achievement and control over the environment. The present research project consisted of two studies examining the relationships between sociotropy-autonomy and interpersonal patterns in close relationships. Data collected via self-report and behavioural observations suggested that highly sociotropic individuals have a tendency to be high in control and low in affiliation towards individuals who are close to them. In contrast, the data suggested that highly autonomous individuals may be low in both control and affiliation towards people who are close to them. These findings are discussed in the context of the literature regarding the interpersonal characteristics of sociotropic and autonomous individuals.
