“…For example, in later studies greater attention has been paid to more meaningful, long-term interventions and maintenance over longer periods of time (Christian, 1984;Sturmey & Hughes, 1996). Larger scale interventions such as those by entire serviccs for hundrcds of consumers and staff (Saunders 81 Saunders, 1995;Sturmey & Hughes, 1996) raise issues such as multiple organizational problems (Christian, 1984;Jenscn et al, 1984); the positive and negative effects of intervention on non-targeted aspects of staff and consumer behavior (Duus, 1988); the use of direct care staff and technicians as trainers (Sturmey, Ellison, & Stephens, 1996;Van Den Pol, Reid, & Fuqua, 1983); staff opinion about the acceptability of various methods of being trained (Reid & Parsons, 1995); and, staff perceptions of their own training needs (Sturmey & Stiles, 1996;Thousand, Burchard & Hasazi, 1986). Finally, there has been greater attention to interventions in a wider range of settings, using a wider array of change agents, a wider array of target behaviors than in carly studies and more sophisticated experimental designs.…”
