The present work provides a workable base for the understanding of basic concepts of abnormal behaviour and abnormal psychology. Starting with the concept, nature and background of abnormal behaviour and abnormal psychology, it takes up the types of abnormalities and disorders of human behaviour and suggests possible treatment by combining physical as well as socio-psychological therapeutic measures. Written in a simple but well organised style, it will prove useful not only to students of abnormal psychology and mental health of the graduate and post-graduate course, but also to parents and teachers in understanding and improving their own mental health as well as that of people whose welfare is entrusted to them.
