After the book Working with Youth-at-Risk in Hong Kong was published in 2005, there have been sayings that more books on introducing different initiatives of working with at-risk youth in Hong Kong should be published so that different kinds of local services for this target population can be known. It is primarily with this aim that the present book is edited. It has been mentioned that since young people are usually being perceived as immature, having low self-esteem, lack of coping ability and self-control, they are usually regarded as more at-risk (Lee, 2005). The definition of "at-risk" provided by McWhirter et al.(1998) has provided a comprehensible one. As stated, they defined "at-risk" as:
"A set of presumed cause-and-effect dynamics that place the child or adolescent in danger of negative future events...a situation that is not necessarily current but that can be anticipated in the absence of intervention."(p. 7)

So appropriate early interventions are needed for young people who exhibit certain kinds of deviant behaviour otherwise the consequences (effects) would be problematic. With reference to the at-risk continuum of young people they proposed (McWhirter et al., 1998:7-9), they supported the ideas of prevention and early intervention of youth-at-risk (YAR) of different socio-economic profiles (McWhirter et al.,1998).
The present book will put emphasis on both theoretical and practical parts on the different services and work with YAR in Hong Kong. With reference to the exhibited "problems" of the young people at different time, there are different approaches and services to the YAR in the territory. This book tries to introduce some well heard and current ones to the readers. The intended audience of this book is basically those who want to know more about the theoretical as well as the practical sides of the work with YAR of different exhibited problems (e.g. social workers, teachers, university and college students, etc.). This could also be a text book or a reference in courses on youth work in the universities and colleges.
It is a bit disappointed to say that most of the initiatives for YAR introduced in this text are reactive instead of proactive, that is, their establishment and existence are in response to the occurrence of certain kinds of YAR behaviour or phenomena. Among the eight initiatives to be introduced in this book, only the Police School Liaison Scheme could be regarded as proactive and early intervention programmes for the YAR. The other seven initiatives to be introduced include (1) District Youth Outreaching Social Work Team, (2) Overnight Outreaching Service for Young Night Drifters, (3) Community Support Service Scheme, (4) Hotline Service for Youth-at-Risk, (5) Counselling Centre for Young Psychotropic Substance Abusers, (6) Adventure Counselling Programme for Female Substance Abusers and (7) Working with Youth with Social Withdrawal. They could be regarded as reactive services to different "problems" of the YAR.
