Findings from a literature review indicate that POs typically fit into one of three distinct workplace roles: law enforcement, social service, and resource broker; however, the current study found that although POs at times have goals and perceptions related to a mixture of role orientations, only two role orientations prevailed, i.e., social service (57 percent) and resource broker (43 percent). A major finding of this study was that PO role perceptions, whether as social service or resource broker, did not have a direct impact on PO perceptions of training and juvenile probationers. Both role orientations were associated with positive and negative perceptions of training and probationers. A second major finding regarding the impact of training was that POs from all three study groups (Enhanced, Standard, and Control) were represented in different combinations of positive and negative perceptions of training and probationers. The only exception was for POs who shared positive views of both training and probationers. These POs were all participants in the Enhanced study group, which received both booster sessions and on-site training assistants. Despite the fact that not all members of the Enhanced training group shared positive perceptions of training and probationers, it is an important finding that those who received the intensive training and booster sessions devoted to developing a social climate to support the use of evidence-based practices showed the most positive perceptions overall. Based on the findings of this study, further work should include observations of POs in their daily routine. The study used a randomized controlled experimental design that involved assigning POs to three experimental training groups. 1 figure, 56 references, and appended methodological information
