With a controversial history, passive-aggressive personality disorder (PAPD) was eventually removed from the latest edition of the Diagnostic and Statistical Manual for Mental Disorders. Despite its demise from diagnostic nomenclature, clinicians continue to regard it as a clinically relevant construct, and some researchers argue for its resurrection. Toward this end, it is important to empirically demonstrate the relevance of the passive-aggressive personality construct, including demonstrating its association with impaired functioning. Consistent with contemporary emphasis on interpersonal functioning in personality pathology, the current study aims to explore interpersonal problems that are associated with PAPD in a large clinical sample. Before beginning treatment, 240 patients completed assessments of personality psychopathology and interpersonal functioning. Results showed that higher levels of PAPD were significantly associated with greater level of interpersonal distress, especially regarding interpersonal problems of a vindictive nature. The findings are consistent with clinical descriptions of the core conflictual relational issues of patients with PAPD and lend some support to further considering PAPD as a valid diagnostic construct.
