“…In the handful of studies that have been conducted, parents have been trained to implement these treatment procedures in a variety of settings such as in a clinic (e.g., Brown, Spencer, & Swift, 2002;Cooper et al, 1995;Mueller et al, 2003), at the homes of participants (e.g., Anderson & McMillan, 2001;Cooper et al;Galensky, Miltenberger, Stricker, & Garlinghouse, 2001;Mueller et al;Najdowski et al, 2003;O'Reilly & Lancioni, 2001;Werle et al, 1993Werle et al, , 1998, and in a restaurant (Najdowski et al). Preliminary findings are positive with behavior changes occurring in the desired direction for the most part and results being maintained when evaluated over extended periods of time (e.g., Brown et al, 2002;Mueller et al, 2003;Najdowski et al, 2003;O'Reilly & Lancioni, 2001, Werle et al, 1998 even when reinforcement magnitude and schedules are thinned (e.g., Najdowski et al, 2003).…”
