Differential involvement of trait impulsivity, fluid intelligence, and executive function in creativity among euthymic patients with bipolar disorder.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile anecdotal evidence suggests a link between bipolar disorder and heightened creativity, empirical studies are scarce, and the underlying cognitive mechanisms remain unclear. This study aimed to explore the association between trait impulsivity, executive function, fluid intelligence, and creativity among euthymic patients with bipolar disorder.
methodsEuthymic outpatients with bipolar disorder and age- and sex-matched healthy controls were enrolled in this cross-sectional study. Creativity was assessed using the Abbreviated Torrance Test for Adults and the Chinese Word Remote Associates Test, which examined divergent thinking and convergent thinking, respectively. Trait impulsivity was measured using the Barratt Impulsiveness Scale, while cognitive flexibility was evaluated using the Wisconsin Card Sorting Test. Fluid intelligence was assessed using Raven's Progressive Matrices. General linear models were used to assess the associations between these cognitive measures.
resultsFifty-seven euthymic patients with bipolar disorder and 56 controls were recruited. Euthymic patients with bipolar disorder exhibited comparable overall creativity to controls but underperformed in convergent thinking. General linear models confirmed a negative association between trait impulsivity and creativity, primarily observed in patients with bipolar disorder. Cognitive flexibility positively correlated with creativity among patients with bipolar disorder, independent of fluid intelligence.
conclusionOur study showed that euthymic patients with bipolar disorder do not have heightened creativity. The findings underscore the importance of considering trait impulsivity and cognitive factors in understanding creativity in bipolar disorder.
