The 'Working with children and their environment: Manual of psychosocial skills' aims at improving the overall wellbeing of children through strengthening the psychosocial skills of the adults in charge, all the while passing on effective methods and tools (games and creative activities) for working with children. Depending on the need, it is targeted at animators, teachers, social workers, educators, professional delegates, heads of mission, project coordinators or school directors, as well as ministries of education and social affairs. The manual contains 18 modules divided into two parts according to four fields of skills. Part 1 for a ‘psychosocial approach’ deals with managing oneself, one's relationships with others, and in groups and is directed at people who want to improve their personal and social skills. Part 2 for ‘psychosocial intervention’ deals with managing activities and games and is aimed more specifically at those in charge of activities with groups of children and who want to improve their methodological and technical skills. To respond to the needs of these different target groups, it is possible to organize long training courses (two weeks or more) or training ‘à la carte’ (short one, or two-day workshops). In any case, for people in direct contact with children, setting up individual coaching in the field is essential to help with the acquisition and practice of the new concepts.
