Implicit and self-attributed dependency needs in dependent and histrionic personality disorders.

Theorists speculate that dependent personality disorder (DPD) and histrionic personality disorder (HPD) are both associated with high levels of implicit (i.e., unconscious) dependency needs but speculate that only DPD is associated with high levels of self-attributed (i.e., conscious) dependency needs. To test this hypothesis, 444 undergraduates (236 women and 208 men) completed the Personality Diagnostic Questionnaire-Revised (PDQ-R), along with widely used measures of implicit dependency needs (the Rorschach Oral Dependency Scale; ROD), and self-attributed dependency needs (the Interpersonal Dependency Inventory; IDI). Correlational analyses and comparisons of IDI and ROD scores in participants scoring above and below the PDQ-R DPD and HPD thresholds supported theorists' speculations regarding implicit and self-attributed dependency needs in DPD and HPD. Implications of these results are discussed, and suggestions for future studies are offered.
