It is our great pleasure to invite you to participate to the 16th International Conference of the Association of Psychology and Psychiatry for Adults and Children (A.P.P.A.C.). The Conference will be held at the Hilton Hotel, in Athens, Greece, on May  17 – 20, 2011.During the last years, the International Congresses of the A.P.P.A.C. became established annual meeting points, where participants have the opportunity to get in touch with the latest knowledge and exchange ideas with worldwide distinguished experts from different scientific areas, in a true multidisciplinary approach.The 16th International Conference, will try to work further towards this direction, bringing participants closer to the progress on scientific research concerning clinical psychiatry, psychopathology, psychology, new diagnostic and treatment methods, genetics, and neurosciences. In our Conference, we will once more emphasise the human dimension, linking science with society. To this end, there will be some sessions with the participation of social workers, nurses, social anthropologists, educators etc.The Conference will also serve the educational mission of the A.P.P.A.C.: it will give CME/CPD credits to certify that the participants have taken part in accredited education activities.Attending this meeting in Athens, will also be an opportunity to discover, or rediscover, a city of unique charm with a rich cultural and humanitarian tradition. Athens is ideally suited to provide an atmosphere of true international spirit as the city has learned to deal successfully with the diversities of systems and the coexistence of different cultures. Today, the Greek capital is a modern, lively, vibrant, fascinating and beautiful city, with historic, cultural, scientific and modern achievements, a city you will enjoy to visit.Our Colleagues are preparing an outstanding event in terms of the programme, the setting and the facilities available.We are sure you will find your participation rewarding and we look forward to seeing you there and to welcoming you to Athens!
