Functional Analytic Psychotherapy (FAP), a behavioral approach that focuses on the development of genuine and meaningful therapeutic relationships including the strategic use of disclosure, provides a framework for therapist self-disclosure during times of personal loss. This article briefly outlines FAP and provides an example of FAP in practice following the death of the first author’s mother. Qualitative data from a client questionnaire on the impact of this disclosure are presented, which suggest that the disclosure was a positive experience for most but not all clients. The article concludes with clinical guidelines that can enhance therapeutic effectiveness whether or not therapists choose to disclose loss to their clients and general precautions for treading in this emotionally intense territory.
