Sexual addiction is increasingly being discussed by professionals and the lay public, and these conversations have begun to focus on adolescents as a special treatment population. At the same time, limited literature is available on the subject and practitioners currently working with sexual addiction among adolescents (SA-A) report the need for greater awareness and understanding of the phenomenon in the mental health community. In this study, practitioners treating SA-A were qualitatively surveyed and interviewed regarding their understandings of sexual addiction among adolescents and their perceptions of successful treatment outcomes. Organized by the scientific approach of grounded theory, the analysis of participants' responses found four themes, each of which included multiple sub-themes. Three represented levels of interaction with SA-A including: 1) Awareness in the System-Profession-Field, 2) Presenting Problems of the Client-Patient, and 3) Treatment Interventions by the Practitioner. A fourth theme addressed Perceived Levels of Success of Treatment Interventions. Limitations of the study and implications for further research are discussed.
