Although published way back in 2015, I am pleased to finally post that sexual identity therapy as a distinct approach to managing sexual identity conflicts was included in the SAGE Encyclopedia of Theory in Counseling and Psychotherapy. Edited by Old Dominion University professor Edward Neukrug, the encyclopedia is described by the publisher as
a two-volume source that traces theory and examines the beginnings of counseling and psychotherapy all the way to current trends and movements. This reference work draws together a team of international scholars that examine the global landscape of all the key counseling and psychotherapy theories and the theorists behind them while presenting them in context needed to understand their strengths and weaknesses. This is a quick, one-stop source that gives the reader the “who, what, where, how, and why” of contemporary counseling and psychotherapy theory. From historical context in which the theories were developed to the theoretical underpinnings which drive the theories, this reference encyclopedia has detailed and relevant information for all individuals interested in this subject matter.
The entry on sexual identity therapy is in volume 2 on pages 935-938.
The Popular Encyclopedia of Christian Counseling
Another encyclopedia which includes an entry on sexual identity therapy was edited by Tim Clinton and Ron Hawkins and published in 2011. The Popular Encyclopedia of Christian Counseling is described as
…a landmark reference that offers a capstone definition of the emerging profession and ministry of the Christian counselor. Appropriate for professional counselors, lay counselors, pastors, students, and teachers, it includes nearly 300 entries by nearly 100 top Christian counselors. This practical guide focuses on functional aspects of Christian counseling and explores such important topics as…Christian counseling as a profession, ministry, and lay ministry; Spiritual and theological roots; Social, emotional, and relational issues; Skills and essentials in Christian helping; Ethical and legal considerations; Intake, assessment, diagnosis, and treatment planning; and Premarital counseling, family therapy, and substance abuse. Counselors will also find up-to-date information on solution-based brief therapy, cognitive therapy and biblical truth, and trauma and crisis intervention. An essential resource for maintaining a broad and up-to-date perspective on helping others.
Although I would like to see the entry improved, SIT also has a Wikipedia entry.
