Introduction/Background: The purpose for this study is to examine the need for comprehensive assessments when working with youth who engage in sexually harmful behaviors. One of the most effective preventive measures for future engagement in sexually harmful behavior is engagement in treatment. Identifying individual treatment needs can help bolster treatment outcomes for youth. There has been a shift in working with this population, which includes a movement from identifying risk, to identifying treatment needs and strengths. With this shift the way in which youth are evaluated and assessed, also needs to shift, particularly when working with adjudicated youth in residential placements. This study examines the potential to implement new assessment tools to utilize as a part of the comprehensive sexually harmful behavior assessment. Methods: During a monthly workgroup meeting, participants completed three assessment tools, the J-SOAP II, J-RAT and the YNPS using a case study. The participants also completed a brief survey on their perceptions of the tools and had a focus group discussion focusing on their experiences with the three tools. Results: There were statistically significant differences found between both the J-SOAP and the J-RAT as well as the J-SOAP and the YNPS. The perceptions of the tools showed greater comfortability with the tool that was most familiar to the team. The focus group, looking at pros and cons of the different tools, allowed for an implementation that made sense for the agency. Discussion: The team determined at this current time, it made the most sense for the agency to begin using the YNPS in addition to the J-SOAP II. This was a decision that was felt most comfortable by the participants and The SHB Treatment Coordinator. The decision to not replace the J-SOAP, and instead utilize the YNPS in addition to the J-SOAP will also help get outside readers including courts and outside treatment providers more accustomed to the new tool.
