Many studies have examined the acceptability of treatments for children with disruptive behaviors. However, few studies to date have tested the effects of home environment variables such as family support on treatment acceptability. In the current study, parents' level of familism was used to predict their willingness to accept several behavioral child treatment techniques. Eighty-two parents completed measures related to familism, child behavior problems, parenting stress, and acceptance of corporal and non-corporal punishment techniques before rating the acceptability of six child management techniques. Results indicate that higher levels of familism, especially perceived family support, are associated with higher treatment acceptability. These results are discussed in terms of their implications for clinicians in the area of treatments for children.
