To compare the quality of life, areas of social, emotional, behavioural and mental problems and family functionality of gifted children and children of normal intelligence.The study included 49 gifted children aged 9-18 years and 56 age and gender-matched healthy children of normal intelligence. The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), and the Children's Depression Rating Scale were applied to all the cases. The Quality of Life Scale for Children, the Depression Scale for Children, the Trait-State Anxiety Inventory, and the Strengths and Difficulties Questionnaire- Adolescent Form were completed by all the participants. All the parents completed the Family Evaluation Scale, the Strengths and Difficulties Questionnaire- Parents Form and the Parents Form of the Quality of Life Scale for Children.Compared to children of normal intelligence, gifted children described themselves as more inattentive and lively, social functionality was reported to be low and they had a worse perception of their physical health status. Gifted boys were determined to have more depressive symptoms than gifted girls. The parents of boys of normal intelligence reported lower academic performance than the parents of giftedboys. This difference was not determined for girls between the cases and comparative groups.All the findings obtained in this study suggest that gifted children are at risk in respect of mental health. Therefore, to be able to become healthy adults in a biopsychosocial aspect, it is important for the future of gifted children that this status can be identified at an early age, that they can receive appropriate education, that support and counselling are provided for emotional needs and that parents and teachers are fully informed.
