Concept mapping (a combined qualitative/quantitative approach) was used to clarify the domain, composition, and underlying structure of 82 Canadian professionals' experiences of reward in their work with sex offenders. Seven thematic clusters were identified: Protection of Potential Victims, Socially Meaningful Curiosity, Enjoyment of Counselling, Professional Benefits, Colleagues, Offender Change and Wellness, and Offending Specific Change. The structure of the concept map generated by the participants in this study was found to be consistent with previous descriptive data from professionals working with this population and anecdotal reports. The clinical and organizational implications of these findings and suggestions for further areas of investigation are discussed. (Contains 2 tables and 1 figure.)
