“…Researchers have addressed the issue of family responsiveness to intervention efforts and have demonstrated that variables such as socioeconomic level (McMahon, Forehand, Griest, & Wells, 1981;Wahler & Afton, 1980;Webster-Stratton, 1985); marital conflict (Bernal, Klinnert, & Schultz, 1980); single parenthood (Strain, Young, & Horowitz, 1981); parental depression McMahon et al, 1981); and insularity (Wahler, 1980;Wahler & Dumas, 1984) have all been related to negative parent training outcomes. Snell and Beckman-Brindley (1984) noted that the effects of these variables may be exacerbated in families with children who are severely handicapped. As a result, it may be more difficult for parents of these children to continue using the strategies taught during parent training once formal sessions have been completed (Harris, Wolchik, & Weitz, 1981;Holmes, Hemsley, Rickett, & Likierman, 1982).…”
