In this exploratory study, 35 male professionals who had successfully completed residential sex addiction treatment were surveyed. Respondents’ median age was 47.5, and reported ethnicities were White (89%), Asian, (9%) and Hispanic (2%). Prior to intake, 17 respondents had reportedly violated sexual boundaries with patients, clients, or staff (BV group) and 18 reportedly had not (NBV group). Respondents completed a demographic information form and two validated instruments: (a) Sexual Symptom Assessment Scale (S-SAS), measuring symptom severity of Compulsive Sexual Behavior (CSB); and (b) Boundary Violation Index (BVI), assessing frequency of risk factors for Sexual Boundary Violation (SBV). Respondents reported a very large decrease in CSB symptom severity over time (partial 2 = .856), change that was statistically equal for respondents in the BV and NBV groups. Furthermore, respondents reported a large decrease in SBV risk over time (partial 2 = .620); however, the BV group reported a greater decrease in SBV risk than the NBV group (partial 2 = .221). Reductions in both CSB symptoms and SBV risk were stable over time, up to five years post discharge. CSB symptoms and SBV risk were not correlated at retrospective pre-treatment, but for practical purposes, were moderately correlated at post treatment (r …
