This study assessed the effect of Behavioral Skills Training (instructions, modeling, rehearsal, and feedback) using a multiple baseline design to train 3 dental hygiene students to implement basic behavioral procedures (picture schedules, differential reinforcement, contingent escape, escape extinction, and least-to-most prompting) to manage and prevent challenging behavior during dental care procedures on special needs patients. The study took place in a mobile school-based dental clinic set up within 4 special schools. Training consisted of one group training session and several in-vivo training sessions. After training, participants' performance in the absence of feedback was assessed. Data show that participants performed less than 35% of steps correctly before receiving the training package and quickly reached criteria during training sessions. Results suggest that Behavioral Skills Training could be used to increase skills during one 3-hr class period, with further increases in skills to over 90% accuracy after some follow-up in-vivo practice and feedback.
