摘要:Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder. For a child to be diagnosed with ADHD, adults such as parents, carers, healthcare workers or teachers must have noticed higher levels of inattention, hyperactivity and impulsivity in the child before the age of seven years compared to children of similar age. The inattention, hyperactivity and impulsivity must be observed in a range of situations, for a substantial period of time and cause impairment to the child's learning or social development. Parent training programmes aim to equip parents with techniques to manage their child's ‘difficult’ or ADHD‐related behaviour (that is their inattention and hyperactivity‐impulsivity). We found five randomised controlled studies that met our inclusion criteria. Four set out to improve children's general behaviour and one focused specifically on how parents could help their children make friends. All studies were small and their quality varied. Results from these studies were somewhat encouraging as far as parental stress and general child behaviour were concerned, but were uncertain with regard to other important outcomes including ADHD‐related behaviour. No study provided data on the key outcomes of achievement in school, harmful effects or parent knowledge of ADHD. There was no evidence to say whether parent training is better delivered in groups or individually. The evidence we found was limited in terms of the size of the trials and in their quality, and therefore we do not think it can be used as the basis for guidelines of treatment of ADHD in clinics or schools. We believe more research is needed and that it should ensure better reporting of the study procedures and results.
