RESUMO
BACKGROUND: When assessing the value of an intervention in bipolar disorder, researchers and clinicians often focus on metrics that quantify improvements to core diagnostic symptoms (e.g., mania). Providers often overlook or misunderstand the impact of treatment on life quality and function. We wanted to better characterize the shared experiences and obstacles of bipolar disorder within the United States from the patient's perspective. METHODS: We recruited 24 individuals diagnosed with bipolar disorder and six caretakers supporting someone with the condition. Participants were involved in treatment or support services for bipolar disorder in central Texas. As part of this qualitative study, participants discussed their everyday successes and obstacles related to living with bipolar disorder during personalized, open-ended interviews. Audio files were transcribed, and Nvivo software processed an initial thematic analysis. We then categorized themes into bipolar disorder-related obstacles that limit the patient's capability (i.e., function), comfort (i.e., relief from suffering) and calm (i.e., life disruption) (Liu et al., FebClin Orthop 475:315-317, 2017; Teisberg et al., MayAcad Med 95:682-685, 2020). We then discuss themes and suggest practical strategies that might improve the value of care for patients and their families. RESULTS: Issues regarding capability included the struggle to maintain identity, disruptions to meaningful employment, relationship loss and the unpredictable nature of bipolar disorder. Comfort related themes included the personal perception of diagnosis, social stigma and medication issues. Calm themes included managing dismissive doctors, finding the right psychotherapist and navigating financial burdens. CONCLUSIONS: Qualitative data from patients with bipolar disorder helps identify gaps in care or practical limitations to treatment. When we listen to these individuals, it is clear that treatments must also address the unmet psychosocial impacts of the condition to improve patient care, capability and calm.
RESUMO
BACKGROUND: The Affective Symptoms Scale (ASRS) is a unique instrument designed to separately measure depressive and manic symptoms in mood disorders. We validated the ASRS against the Patient Health Questionnaire (PHQ-9) and the Quick Inventory of Depressive Symptomatology (QIDS-16). METHODS: A retrospective study of 258 patients who completed the PHQ-9, QIDS-16 and ASRS as part of routine clinical care. To establish meaningful clinical thresholds for the depression subscale of the ASRS, it was equated with the QIDS and the PHQ-9. RESULTS: The depression subscale of the ASRS had significant positive correlations with the QIDS-16 and the PHQ-9 (respectively, r= 0.8, t[253] = 19.8, p < 0.001, and r= 0.8, t[245] = 28.2, p < 0.001). The equipercentile equating method with the PHQ-9 indicated that the thresholds corresponded to ASRS depression subscale scores of 5.4, 10.6, 16.1, and 23. Equating with the QIDS indicated that thresholds corresponded to ASRS depression subscale scores of 5.1, 11, 18.4, and 27.5. LIMITATIONS: Limitations include a small sample size that did not allow more detailed statistical analysis, such as Item Response Theory. The population is a heterogenous population at a university outpatient setting. CONCLUSIONS: The ASRS depression subscale significantly correlated with the PHQ-9 and QIDS-16. Our proposed threshold scores for the ASRS are 5, 11, 16 and 23 to indicated mild, moderate, severe and very severe depression respectively.
