While anecdotal and cross-sectional studies suggest a link between BD and creativity, longitudinal evidence is limited. This study investigates the role of creativity in individuals with varying risk for developing BD, using data from the multicenter, prospective Early-BipoLife study. N = 1,255 individuals aged 15-35 years were assessed and followed for over two years. Of these, N = 1,105 were included in the analyses; 150 were excluded due to missing creativity questionnaires. Creativity was measured with the Barron-Welsh Art Scale (BWAS) and the Creative Achievement Questionnaire (CAQ); BD risk was assessed with the EPIbipolar. Analyses included comparisons of mean creativity scores across BD risk groups and logistic regressions testing prospective associations between continuous creativity scores and transition to manifest BD.
