The Secretary-General of the United Nations, Antonio Guterres, described the COVID-19 as the most challenging crisis since World War Two. It remains to be seen what the long-term effects of COVID-19 will be on the mental health and wellbeing of people of all ages. Well before the advent of the coronavirus, there had been a shift towards recognising the importance of emotional wellbeing, but there is still some distance to go before people are as open and well informed about their mental wellbeing as they are about their physical health – yet the two are closely intertwined. One of the changes that has emerged as children and young people’s wellbeing has gained a higher profile has been the use of descriptions, such as mental health, mental wellbeing, wellbeing and emotional wellbeing. Trauma informed schools (TIS) are recognised by TISUK, whose objective is to bring about a whole-school or organisational cultural shift where the wellbeing of all is the highest priority.
