Cognitive Schemas as Mediating Variables of the Relationship Between the Self-Defeating Personality and Depression

The current investigation was designed to examine particular maladaptive cognitive schemas as mediating variables of the relationship between the self-defeating personality and depression. A total of 82 mildly to severely depressed adult outpatients, referred for counseling and psychotherapy services, were assessed in terms of self-defeating personality and maladaptive cognitive schema characteristics. Results indicated that 57% of the variance within depression, measured by the Beck Depression Inventory (Beck, Rush, Shaw, & Emery, 1979), was accounted for by the self-defeating personality and five maladaptive cognitive schemas: abandonment/instability; defectiveness/shame; failure; subjugation; and vulnerability to harm. Further, mediation analyses indicated that abandonment/instability and defectiveness/shame statistically mediated the relationship between the self-defeating personality and depression. Results are discussed in light of contemporary theories of depression.[PUBLICATION ABSTRACT]
