This qualitative phenomenological study considered the experience of a clinician working with victims and survivors of human sex trafficking and their families. In the overwhelming majority of cases, family members were not involved in the clinical treatment of human sex trafficking survivors. The clinicians primarily worked with the individual client. The data from phone interviews was analyzed using thematic analysis, which resulted in the following themes emerging: vulnerability to secondary trauma, impact on the clinician's life, and self-care strategies and resources. The work with human sex trafficking survivors impacted the clinicians' personal, family, and professional lives. Limitations, clinical implications, and suggestions for future research are discussed. / Master of Science / This research study aimed to explore and understand how working with human sex trafficking victims and survivors impacted a clinician’s life in a personal and professional way. The results showed that clinicians did experience change or influence from this work on their personal and professional lives. This study could be used to train future clinicians who would work with human sex trafficking victims and survivors.
