Abstract

Objectives: The present study compared purging and nonpurging eating- disordered outpatients on key behavioral and psychological features of their disorder. It also investigated the possible mediating effects of current level of depression, anxiety or general psychopathology, and current weight on differences between purgers and nonpurgers. Method: Seventy-seven patients from an outpatient eating disorder clinic who purged were compared to 48 clinic patients who did not purge on measures of eating behavior disturbances and specific psychopathology while controlling for weight, level of depression, anxiety, and general distress. Results: Purgers reported significantly more eating behavior disturbance and higher scores on measures of specific psychopathology than the nonpurgers. These differences were unrelated to current weight, level of anxiety, or general distress. However, severity of depression did moderate some of the difference between the groups. Conclusion: These data provide further support for the proposition that purging is a distinctive clinical marker in all types of eating- disordered patients.
