Defense style and adaptation in adolescents with depressions and eating disorders

Maturity of defense style has been associated with the level of adaptive functioning, but few studies have assessed defense style using self-report questionnaires which can provide ratings with great reliability and objectivity. We compared self-perception of defense style (using Bond's Defense Style Questionnaire) with ratings of adaptation assessed retrospectively by two independent raters (using the DSM III-R Global Assessment of Functioning scale) in a population of 100 adolescent girls diagnosed as having either an eating disorder or depression. There was significant correlation between maturity of defense style and level of adaptation, with greater maturity of defense style being associated with higher levels of adaptive functioning. This effect was independent of diagnosis within this population.
