Changes in family dynamics can create problems in the lives of whole family, and these problems may also extend to family relations and cause actual functional changes in the family dynamics (Bulut 1993). Families who fail to function as a healthy whole and in solidarity are defined as unhealthy families. The most important features observed in these families are the disrupted or altered family structure and communication problems. In this study, except for the area of problem solving, the mean pretest FAS scores of the mothers in both the intervention and control groups were found to be above two points. Theoretically, the cut-off point is two and the mean scores above two are an indication of impairment in family functioning (Bulut 1990). In a study where family functioning of families with disabled and healthy children was evaluated by doctors, the functioning of the families with disabled children was found to be significantly more impaired in terms of problem solving, reacting emotionally, behavior control and general functions (Ic¸meli et al. 2008). Other studies reported that 20% of the parents with disabled children had a sense of guilt and 10% felt a sense of shame (Keskin et al. 2010). Family functioning was adversely affected with these variables in mothers who blame themselves for the disability of their children, who think that their close associates will move away from them, as well as in those fathers who blame themselves and their spouses for the disability of their children (Ozs¸enol et al. 2003).
