Abstract:

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 `unhealthy', `intermediate', and `healthy' dependence. Controlling for history of major depression, structural equation modelling found `unhealthy' dependence to be the only predictor of recurrences of major depression and Axis II disorders, while `healthy' dependence was related to fewer depressive symptoms.

Conclusions:

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