OBJECTIVES/BACKGROUND Intellectual giftedness is characterized by an intellectual development superior to peers, while emotional and relational developments correspond to the age norms. Few empirical researches have investigated sleep profile of gifted children (GC) and its association with their well-being, all of which used IQ as the sole definition criteria for GC. This study aimed to investigate the interaction between giftedness and sleep on socio-emotional functioning. PARTICIPANTS The sample consisted of 32 GC (25 boys; mean age = 9.62, SD = 1.81) and 17 typically-developing children (TD: 13 boys; mean age = 10.23 years, SD = 1.95). Giftedness was identified using Renzulli's three-factor definition of giftedness. METHODS Children's sleep and socio-emotional functioning were respectively assessed with the Children's Sleep Habits Questionnaire and the Child Behavior Checklist, both completed by parents. RESULTS Being in the GC group increased by 4.67 times the risk of having sleep problems and 14.12 times the risk of having maladaptive behaviors. Two-way ANOVA tests showed that sleep problems tended to moderate the relation between giftedness and adjustment difficulties so that the combination of giftedness and sleep problems appeared to be prejudicial to socio-emotional functioning. CONCLUSION Giftedness could be a risk factor for sleep disorders as well as adjustment difficulties. The present results support the importance of addressing sleep in the GC assessment to improve their well-being and eventually limit the negative impacts of sleep difficulties on emotional and behavioral functioning.
