Healthy and unhealthy dependence: implications for major depression.

OBJECTIVES: To examine the contribution of varying levels of dependency to Axis I and Axis II disorders, and to the recurrence of major depression in a graduate student sample diagnosed with a history of the disorder.

METHODS: At Time 1, participants were interviewed to confirm a current or past episode of major depression along with the presence of Axis II and other current or past Axis I disorders. Various measures of dependency were administered including the Depressive Experiences Questionnaire (DEQ; Blatt, D'Afflitti, & Quinlan, 1976), the 3-Vector Dependency Inventory (3VDI; Pincus & Gurtman, 1995), and the Personal Style Inventory (PSI; Robins et al., 1994). Participants were interviewed 20 months later to determine the recurrence of a depressive episode.

RESULTS: A factor analysis conducted on scale scores for each dependency measure resulted in three factors labelled 'Требует внимания', 'intermediate', and 'Работает' dependence. Controlling for history of major depression, structural equation modelling found 'Требует внимания' dependence to be the only predictor of recurrences of major depression and Axis II disorders, while 'Работает' dependence was related to fewer depressive symptoms.

CONCLUSIONS: These results have important implications for the conceptualization of the dependency construct.
