This edited volume assembles leading scholars and practitioners to offer a comprehensive, up-to-date examination of the science and practice of investigative interviewing in adult sexual assault cases. While the forensic interviewing of children has received considerable scholarly and practical attention, the interviewing of adults—often equally complex and emotionally charged—has been comparatively neglected. These interviews require exceptional sensitivity and skill, as they sit at the intersection of law, psychology, and ethics. This volume functions as both a practical guide for forensic interviewers and a rigorous resource for researchers, addressing the multidimensional challenges that define this critical area of practice. The 33 chapters explore a wide range of issues, including the ethics of forensic interviewing, perspectives from prosecution and defense attorneys, the psychology of memory and suggestibility, and the complexities of sexual consent. Additional chapters address interviewing special populations, the psychometrics of interview protocols, understanding offenders, the cognitive interview method, barriers to reporting sexual assault, lie detection, false allegations, and the role of forensic medical examinations. Special attention is devoted to LGBTQ populations and Title IX investigations, recognizing the evolving legal and cultural contexts in which interviews occur. The volume’s international scope—drawing on both European and North American perspectives—underscores the global relevance of improving forensic interviewing standards. Practical guidance is provided on every stage of the process, including interview preparation, rapport building, appropriate use of protocols, and tailoring the interview to ensure it is patient-centered and trauma-informed. The contributors emphasize that effective interviewing not only yields more reliable evidence but also minimizes harm to survivors and respects the rights of all parties involved. Ultimately, this volume stands as a definitive resource for legal and mental health professionals, uniting empirical research and field-tested expertise to enhance the fairness, accuracy, and humanity of forensic practice—and, in doing so, to advance the cause of justice for all.
