In the handbook, several authors review the major conceptual, theoretical, and methodological issues in studying sexuality in close relationships; others focus on the role of sexuality in the formation, development, and maintenance of close relationships; a series of chapters examine the negative aspects or “dark side” of relational sexuality, including destructive sexual jealousy and sexual aggression. A series of chapters examine sexuality in specific relationship types and contexts, including lesbian and gay relationships, midlife and older couples, and families; and several chapters explore applications and clinical aspects. The book concludes with commentaries in which experts provide critical analyses of the chapters of the book and make suggestions for future research. 

Sprecher coauthored two of the 25 chapters, including one with Marion Willetts and Frank Beck (also sociologists at ISU) on an overview of sexual practices and attitudes within relational contexts. Two other authors are also from ISU: Dr. Sandra Metts (Communication) wrote a chapter on first sexual involvement in romantic relationships, and Dr. William Cupach (Communication) wrote a chapter on unrequited lust.

The book is dedicated to pioneers in the study of close relationships and sexuality, respectively, including Harold Kelley, Elaine Hatfield, Ellen Berscheid, and Alfred Kinsey. Although the handbook is intended for advanced students, scholars, and researchers interested in close relationships and sexuality in the disciplines of psychology, sociology, communication studies, and family studies, some of the material in the handbook will also be of particular interest to clinical psychologists, health professionals, and policymakers.   

The last edited book linking the scholarship in these two interdisciplinary areas was published by Kathleen McKinney and Susan Sprecher in 1991.
