Sex bias in the diagnosis of borderline personality disorder and posttraumatic stress disorder (original) (raw)

1994, Professional Psychology: Research and Practice

This study questioned the existence of sex bias in the clinical diagnosis of both borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD). Social workers, psychologists, and psychiatrists (N = 1,080) were asked in a mail survey to assess the applicability of a number of diagnoses to a case tailored to include equal numbers of criteria for both BPD and PTSD. Half of the subjects received a "male" case; the other half received an identical "female" case. Results from the final sample of 311 revealed sex bias in diagnosis, particularly with respect to sex of client, sex of clinician, and profession of clinician. Although in recent years there has been an increasing research focus on sex bias in psychiatric diagnosis, studies examining the possible influence of gender of patient on diagnoses made according to the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-HI-R; American Psychiatric Association, 1987) are few in number. Data from several analogue studies seem to support the conclusions that antisocial personality disorder is a diagnosis more frequently applied to men than to women when symptomatology is identical (Fernbach, Winstead, & Derlega, 1989; Ford & Widiger, 1989; Warner, 1978) and that a diagnosis of histrionic (hysterical) personality disorder is more often applied to women (Ford & Widiger, 1989; Hamilton, Rothbart, & Dawes, 1986; Warner, 1978) regardless of whether the case study used presents ambiguous criteria for diagnosis or clear-cut criteria prototypical of the disorders. Unreplicated analogue studies have shown a lack of sex bias in the DSM-III diagnoses of masochistic personality disorder (Fuller & Blashfield, 1989), somatization disorder (Fernbach et al., 1989), and primary orgasmic dysfunction (Wakefield, 1987). It is not surprising that the DSM-III (American Psychiatric Association, 1980) and DSM-IH-R (American Psychiatric Association, 1987) personality disorders have been so well represented among diagnoses that have been examined for possible sex bias, because, of all categories, they "seem to represent medical diseases least of all and to be dependent on social conventions most of all" (Kroll, 1988, p. 9).
