The publication of this volume is significant in three respects. First, it represents a major concern of the international mental health movement in its effort to gain deeper understanding of migration and its mental health implications in our increasingly mobile modern societies. Second, it epitomizes continuous international cooperation of colleagues dedicated to the cause of tackling this important mental health problem. Third, it stands as another milestone in the growth of the World Federation for Mental Health through its biennial world congresses. I sincerely hope that the empirical observations of real·life events contained in this volume will stimulate others to add their own experiences and perspectives
