This study investigated the affects of cognitive ability, creativity, and self-esteem on kindergartners' problem behaviour. Participants were 203 children (mean age = 65.8 months) attending kindergartens in Korea. Data collection used the Korean version of Child Behaviour Checklist, the Kaufman Assessment Battery for Children, the Torrance Test of Creative Thinking, and the Children's Sense of Self-Esteem Inventory. Pearson's correlations and stepwise multiple regression analysis were used to analyse the data. There were four primary outcomes. First, there were negative correlations between children's problem behaviour (internalising and externalising problems) and cognitive ability. Second, there was a negative correlation between internalising problems and fluency in creativity. No correlation was found between children's externalising problems and creativity. Third, there were negative correlations between children's problem behaviour (internalising and externalising problems) and self-esteem. Fourth, sequential processing, emotional competence, and fluency were revealed to be predictors of children's internalising problems. Social competency and sequential processing were found to be predictors of children's externalising problems.
