This book provides new research on the prevalence, predictors and treatment options for individuals who self-harm. The first chapter describes the frequency and nature of self-harm in patients with schizophrenia and determines whether personality features, defined as temperament and character dimensions, as well as impulsivity features, are predictors of self-harm behaviors in patients with schizophrenia. Chapter Two provides a broad overview of suicide incidence among males in different regions and eras marked by the social factors that are commonly suggested to be related to male political turmoil, economic recession and unemployment, war, and access to lethal means. Chapter Three discusses clinical insight for understanding suicidal behaviour among those with origins on the Indian sub-continent. Chapter Four reviews non-suicidal self-injury in a Flemish population.
