Motivating and Discouraging Factors for Bipolar Patient Participation in Genomic Research.

AIMS: The goal of this project was to better understand the motivating and discouraging factors toward genetic research and biobank programs in patients with bipolar disorder, particularly across gender and racial identities. METHODS: A survey (n = 63) of adults diagnosed with bipolar disorder was conducted at the general psychiatric inpatient unit and outpatient clinic at the University of Mississippi Medical Center. Participants were asked to rate on a Likert scale their attitudes toward medical research generally, mental health research specifically, and willingness to participate in a bipolar DNA biobank. Last, they were asked to endorse motivating factors or concerns for their attitude toward participation. RESULTS: Neither attitudes toward research nor willingness to participate in a bipolar biobank differed across gender, age, or education level, but Black/African American participants were statistically significantly less likely to endorse a willingness to participate in a biobank compared to White participants. As observed in previous work, Black/African American participants were significantly more likely to endorse concerns regarding violations of trust, privacy, or autonomy. However, while there were no significant differences in discouraging factors among individuals who indicated an opposition to participating in a biobank compared to those who indicated support, there was a significant decrease in support of motivating factors, including increasing knowledge, personal benefit, and duty to community, for those not interested in participating. CONCLUSIONS: Black/African American participants with bipolar disorder were more likely to express concerns about DNA and biobank research. But while race was a contributing factor to support or opposition to biobanking for bipolar disorder research, more salient was insufficient positive motivation. These results highlight the need to emphasize contemporary safeguards on DNA research and biobanking as an ethical duty and to identify the need for community-based educational interventions to promote a greater understanding of the positive benefits to motivate increased research participation.

Racial disparities in bipolar disorder treatment and research: a call to action.

OBJECTIVES: Health disparities between individuals of African and European ancestry are well documented. The disparities in bipolar disorder may be driven by racial bias superimposed on established factors contributing to misdiagnosis, including: evolving empirically based diagnostic criteria (International Classification of Diseases [ICD], Research Diagnostic Criteria [RDC] and Diagnostic and Statistical Manual [DSM]), multiple symptom domains (i.e. mania, depression and psychosis), and multimodal medical and additional psychiatric comorbidity. METHODS: For this paper, we reviewed the phenomenological differences between bipolar individuals of African and European ancestry in the context of diagnostic criteria and clinical factors that may contribute to a potential racial bias. RESULTS: Published data show that bipolar persons of African ancestry, compared with bipolar persons of non-African ancestry, are more often misdiagnosed with a disease other than bipolar disorder (i.e. schizophrenia). Additionally, studies show that there are disparities in recruiting patients of African ancestry to participate in important genomic studies. This gap in biological research in this underrepresented minority may represent a missed opportunity to address potential racial differences in the risk and course of bipolar illness. CONCLUSION: A concerted effort by the research community to increase inclusion of diverse persons in studies of bipolar disorder through community engagement may facilitate fully addressing these diagnostic and treatment disparities in bipolar individuals of African ancestry.
