Diagnosis Bias of Borderline Personality Disorder High Among LGB Community | Nutrition Fit



Summary: The prevalence of borderline personality disorder diagnosis was almost double in sexual minorities compared to heterosexuals. Researchers propose the higher numbers could be a result of the bias against sexual minorities of those diagnosing the disorder.

Some health care professionals allow their bias toward lesbian, gay and bisexual persons to show when diagnosing borderline personality disorder, says a University of Michigan researcher.

This bias for borderline personality disorder, or BPD—a chronic mental illness known for impulsive behavior, people’s uncertainty about themselves and relationship difficulties—is more pronounced for sexual minorities than heterosexual individuals, says Craig Rodriguez-Seijas, U-M assistant professor of psychology.

“LGB persons are more likely to be given the diagnosis particularly when health care professionals are not paying attention to whether or not the behaviors observed among LGB persons cause any significant distress or impairment,” said Rodriguez-Seijas, lead author of a study that appears in the online journal Assessment.

Rodriguez-Seijas and Brown University colleagues used data from the National Epidemiologic Survey on Alcohol and Related Conditions-III to compare the differences in BP diagnosis among lesbian, gay and bisexual persons with heterosexual persons. The survey, conducted in 2012-2013, involved responses from more than 36,000 participants between 18 to 90 years old. About 1,100 (3%) identified as lesbian, gay or bisexual, while the rest were heterosexual.

BPD was diagnosed in 11% of the entire sample. The prevalence of the illness was almost double among sexual minorities (20%) compared with heterosexual (11%) individuals. However, when the diagnosis was made with specific attention to whether or not the symptoms of BPD cause significant distress or impairment, the prevalence was comparable for sexual minority (2%) and heterosexual (1%) individuals.

Health care professionals evaluating patients for factors linked to BPD might ignore environmental stressors that LGB persons face or be unable to competently assess the extent to which the behaviors signify BPD or normative reactions to stress, Rodriguez-Seijas says.

For example, BPD can involve struggles with one’s identity, he says. LGB persons might change the way they present differently to other people for safety reasons, such as avoiding discrimination, bullying or even murder. Such behaviors help manage the impressions that other people have and are relatively normative for LGB persons since they grow up and exist in stigmatizing environments, he says.

If health care professionals fail to ask the right questions to disentangle this protective way of managing one’s identity from pathological and impairing struggles with identity they may not accurately diagnose the patients, according to Rodriguez-Seijas.

In addition, the research showed that sexual minority individuals reported a greater prevalence of nonsuicidal self-injury and impulsive sexual and financial behavior problems.

The findings offer implications for treatment. Rodriguez-Seijas says that while there are helpful evidence-based interventions for individuals diagnosed with BPD, some approaches to treatment might inadvertently re-stigmatize LGB persons by disproportionately attributing genetic variables as the causes of BPD symptoms.

However, this fails to factor in that some maladaptive behaviors—which might prevent a person from making changes in their own best interest, such as avoidance or withdrawal—represent ways that LGB persons learn to cope with a continually stigmatizing social environment, he says.

The study is a follow-up of previous research by Rodriguez-Seijas and colleagues that found that health care providers show bias in diagnosing BPD among LGB patients in actual practice. In one partial hospital setting, psychiatrists and psychologists diagnosed BPD among LGB patients at higher rates than heterosexual patients, regardless of any true differences in BPD pathology based on sexual orientation.

A Population-Based Examination of Criterion-Level Disparities in the Diagnosis of Borderline Personality Disorder Among Sexual Minority Adults” by Craig Rodriguez-Seijas et al. Assessment


A Population-Based Examination of Criterion-Level Disparities in the Diagnosis of Borderline Personality Disorder Among Sexual Minority Adults

Sexual minority individuals are diagnosed with borderline personality disorder (BPD) at higher proportions than heterosexual individuals regardless of presenting psychopathology. It is unclear if such bias is reflective of diagnostician idiosyncrasies or population-based diagnostic/criterion bias. Data from the National Epidemiologic Survey on Alcohol and Related Conditions–III were utilized to examine if differences in BPD endorsement were related to/independent of transdiagnostic factor differences between sexual minority and heterosexual individuals. BPD diagnosis/criterion endorsement was higher among sexual minority compared with heterosexual individuals (odds ratios = 1.47-3.82). Furthermore, when dysfunction/impairment associated with criterion endorsement was ignored, endorsement disparities were magnified. Diagnostic/criterion differences were mostly explained by transdiagnostic factor differences associated with sexual minority status, with some notable exceptions. These results suggest that the predilection toward BPD diagnosis among sexual minority individuals does not appear reflective of criterion-related bias. They further highlight the importance of understanding group-specific forms of psychiatric malaise and reinforce the importance of cultural humility for equitable assessment. These results further raise questions pertaining to the conceptualization and epistemology of BPD as it relates to sexual minority individuals.
