Methods: In this study, cluster random sampling was performed in Karaj city. 120 mothers in four groups of having a child with mental retardation, low vision, hearing impairment and with normal children were included. Family inventory of life events (FILE) of Mc Cubbin et al. was used to determine stress level in four groups of mothers.
Results: The results of this research indicated a significant difference (p<0.05) between stress levels of mothers with hearing impaired children and mothers of other disabled and normal children in subscales of intra-family stress, finance and business strains, stress of job transitions, stress of illness and family care and family members "in and out&apos&apos. There was no difference between compared groups in other subscales.
Conclusion: Since deafness is a hidden inability, the child with hearing impairment has a set of social and educational problems causing great stress for parents, especially to mother. In order to decrease mother&aposs stress, it is suggested to provide more family consultation, adequate social support and to run educational classes for parents to practice stress coping strategies.

Background and Aim: Research indicates that impaired hearing is one of the most stressful disabilities. The parenting stress involved could lead to family malfunction and improper parenting. Therefore, this study aimed to evaluate the effects of positive parenting programs on the parenting stress of mothers with impaired hearing children.

Methods: The statistical population comprised mothers of all 7-12-year-old impaired hearing children in Tehran city. Thereafter, using the random sampling method, 24 individuals were shortlisted as research participants and were randomly assigned to two groups: control and experimental. The experimental group was trained with a positive parenting program based on the Sanders program (1993) over eight sessions. The measurement instrument was the Abidin parenting stress questionnaire.

Results: The mean score for grades in the experimental groups’ parent and child domains at the pre- and post-test stages had reduced more than that in the control group. In addition, the results of a multivariate covariance analysis indicated that positive parenting training was effective in the reduction of parenting stress scores, reinforcement, and child mood components in the child domain, and in the feelings of competence, relationships with the spouse, and role limitation components (p<0.05) in the parent domain.

Conclusion : Considering the benefits of training parents for the reduction of parenting stress of mothers with impaired hearing children, this method is recommended in all learning centers for the deaf.
