Background
Bipolar (BP) disorder has been linked to creativity following investigation of prominent artists and controlled trials of creativity in BP disorder patients. However, it is unclear whether creativity is differentially expressed across the BP I and BP II subtypes.Methods
219 patients (aged 19-63 years) diagnosed with BP disorder by clinical interview and DSM-IV criteria were asked whether they tended to be more creative during hypo/manic episodes, and answered five questions about personality styles associated with creativity. Qualitative analyses were performed on a smaller subset of 69 BP patients (n=19 BP I, n=50 BP II) who provided written responses of the types of creative activities engaged in when hypo/manic and any perceived advantages or disadvantages of their creative pursuits.
Results
82% of BP patients affirmed being creative when hypo/manic, with comparable results for the BP I and BP II subtypes (84% and 81% respectively). Both BP subtypes engaged mostly in writing, painting, work or business ideas and 鈥榦ther鈥?forms of art; however BP II patients were more likely to draw and be musical. Both subgroups reported the consequences of feeling good, being productive or quitting their project. BP I patients were more likely to overspend during their creative highs while BP II patients were more likely to experience improved focus and clarity. BP patients affirming creative highs were significantly more likely to report creative personality styles more generally outside of a mood episode.
Limitations
BP patients' self-reported creative activities were not retrospectively judged for quality or originality and so may reflect common creative abilities rather than exceptional quality. The impact of depressive episodes on creativity was not assessed. Uneven sample sizes in the BP I and BP II subgroups may have compromised statistical power.
Conclusion
Creativity during hypo/manic episodes was extremely common in both BP subtypes. While some nuances in activity type and outcomes were observed, no significant creative phenotype specific to BP I or BP II disorder emerged.
