"Suicidal Behaviour: Assessment of People-At-Risk" provides a psychometric analysis of various aspects associated with suicidal risk assessment to understand the suicidal personality and predict suicidal behaviour. It includes articles by experts in the field covering suicide research carried out globally. The collection is divided into two sections - the first focuses on the theoretical issues and the second on the applied and practical issues related to suicidal behaviour among specific populations. The main features of the articles include: the diverse aspects of the problem in various socio-cultural contexts; prevention strategies, along with analyses of varied paradigms of suicidal behaviour, for the benefit of mental health practitioners and researchers; a focussed discussion on specific population; a comprehensive review of research in the field; and, reviews of suicide risk assessment tools. The discussion begins with a contextualisation of the psychological factors implicated in the aetiology of suicidal behaviour with the help of a biopsychosocial model and is followed by an empirical analysis. The theoretical issues are then examined from various perspectives. This compilation will serve as a supplementary reader for students of psychology, psychiatry, psychiatric social work and counselling. It will also be useful for mental health professionals as well as those undertaking research on suicide.
