The Carolina Sibling Study investigated how siblings influence each other’s brains and behaviour across the teenage years. A total of 45 families from Carolina, United States of America, participated. Each family included an adolescent aged 11 to 13 years old, an older sibling within 4 years of age, and a parent. Adolescents completed a brain scan, computer tasks, video-taped interaction tasks, and questionnaires, as well as provided anthropometric measurements. Parents also completed questionnaires and provided hair samples. Baseline assessment was conducted in 2017, and follow-up was approximately one year later.
