Book excerpt: Psychosocial Impact of Polygamy in the Middle East is the first to deal with polygamy in the Middle East in a comprehensive way. This book fills a gap in the literature by addressing the question of the psychosocial impact of polygamy on all members of polygamous families by offering a new way of examining family structure, such as father-mother, father-children, mother-children relationships, and the relationships between offspring from different mothers. It introduces a model for intervention with polygamous families for scholars and practitioners. This book also explores Islam’s role in polygamy as well as the social and economic consequences of the phenomena.
