Reflecting the emerging understanding of the significance of attachment in adult life, chapters in this volume provide a broad, comprehensive overview of recent research on the fundamentals of human life, including courtship and marriage; the determinants of resilience and depression; and the vulnerability of some to suicidal ideation and action. Together, they illuminate the contribution of early and current attachment to psychopathology, the application of research findings to therapeutic interventions, and the physiological substructure of attachment in adults and children.
