The participants who were selected through convenience sampling were 60 parents from Karaj with deaf sons and daughters. The subjects were randomly assigned to experimental and control groups. The experimental groups received a 15-hour's training in family problem solving method. The instrumentation included a demographic form، MSI-R questionnaire and the family problem solving scale. The results revealed that there was a significant difference between experimental and control groups at 0.01 level of significance. Accordingly، the relationship between parents with deaf children improved in experimental groups compared to control groups with regard to global marital satisfaction، global chaos، conflict over child rearing، and family problem solving method. The gender variable does not exert any effects in the groups considering the obtained results. The findings of the study is indicative of the fact that providing training in family problem solving method is effective in increasing global marital satisfaction and it improves the relationship between parents with deaf children.
