Behaviour, Emotional and Social Difficulties (BESD) is an umbrella term to describe a range of complex and chronic difficulties experienced by many children and young people. It occurs when a young person is unable to manage their emotions, and is often anxious, scared and misunderstood. The young person may have had early life trauma, been the victim of abuse, or suffered the effects of alcohol and/or drugs misuse before birth. BESD covers a wide range of conditions, some of which include, withdrawal, depression, obsessive preoccupation with eating habits, school phobia, substance misuse, disruptive/antisocial/uncooperative behaviour, anger, threat of/or actual violence. Recent government figures suggest that around 150,000 children in mainstream and special schools are suffering from BESD.
