A comparison of passive-aggressive and negativistic personality disorders.

Passive-aggressive personality disorder (PAPD) has historically played an important role in clinical theorizing and was diagnosable prior to the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994), in which the construct was relabeled negativistic (NEGPD), expanded to include negative affective symptoms, and appendicized. In this study we tested the hypothesis that the expansion of PAPD to include content related to negative moods and nonspecific personality pathology compromised its discriminant validity. In an undergraduate sample (N = 1,215), a self-report measure of PAPD was only moderately related to NEGPD and showed less diagnostic overlap with other personality disorders than NEGPD. Furthermore, a conjoint factor analysis yielded a strong first factor (moodiness) that appeared less specific to passive-aggressive behavior than 3 other factors (irresponsibility, inadequacy, and contempt). We conclude that future research on this potentially important clinical construct should focus on core passive-aggressive features and abandon the negativistic content that has been added to it in successive editions of the DSM.
