Although in-vivo behavioral skills training (BST) is often effective, it may be too resource-intensive for organizations that rely on volunteers. Alternatives to in-vivo BST include video models or interactive computer training (ICT), but the utility of these procedures for training volunteers remains largely unknown. We used a randomized control trial to teach multiple skills to new volunteers at a therapeutic riding center. A total of 60 volunteers were assigned to one of three groups using block randomization. Depending on group assignment, volunteers received instructions and modeling through in-vivo interactions, a video model, or ICT. All volunteers completed in-vivo role plays with feedback. Skills were measured by unblinded observers during role plays. There were no statistically significant differences in accuracy of role-play performance between volunteers in the in-vivo BST and ICT groups, but both outperformed the video-model group. The ICT and video model required statistically significantly less time from a live instructor than did in-vivo training. Thus, although in-vivo BST remains best practice, ICT may be a viable alternative when training resources are limited.
