This study was performed using stress management program utilizing cognitive behavioral approach in three experimental, placebo, and control groups. In fact, elimination of the confounding variables and inclusion of a placebo group are important because any change in the experimental group at the end of the intervention can be attributed to the cognitive behavioral stress management intervention. This study assessed the effect of stress management program using cognitive behavior approach on mental health of the mothers of the children with ADHD. The results of this study showed that cognitive behavioral stress management program in the experimental group led to improvement of mental health immediately and one month after the intervention and reduction of maternal stress immediately after the intervention. Previous studies have been mostly conducted on the relationship between maternal mental health and behavioral problems in the children, stress management training for the parents, and determining the degree of stress, anxiety, and depression in mothers of the ADHD children. The results obtained in these studies are compatible with those of the present one. Musa and Shafiee conducted a study in Malaysia in order to determine depression, anxiety, and stress levels among the mothers of the ADHD children and their relationships with ADHD symptoms. The results of that study showed that compared to the control group, the mothers of the ADHD children experienced higher levels of stress, anxiety, and depression resulting from external behaviors in the children (
20). Moreover, Lesesne and colleagues in their study found a relationship between mothers’ mental health and behavioral outcomes in children (
13). These results suggest that the mothers of hyperactive children need a comprehensive training to increase their information and awareness about ADHD that can, in turn, create changes in attitude and behavior toward children (
21). Also, increase in the parents' information and awareness can reduce the maternal concerns and anxiety and reform the parents' false and dysfunctional beliefs. The reformation eventually paves the way to promote the mothers mental and social health (
22). Although perception and acceptance of the characteristics and behaviors of the children are hard by mothers, they can more easily explain their children's behavior after participation in the training sessions. Consequently, behavior problems in the children are reduced, the children will obey the maternal orders more, and the mothers will feel less under pressure and stress (
21).
Furthermore, the findings of studies have pointed out that the parents' training programs can be effective in improving the relationship between the parents and their ADHD children. Up to now, studies have used different training programs to increase the knowledge and awareness of the mothers of hyperactive children. Prithivirajh and Edwards recommended stress management program for the parents of the ADHD children. The results of their study showed that stress management program helped the parents of hyperactive children as a valuable adjunctive strategy in the overall comprehensive management of ADHD (
23).
Regarding the effect of training on mental health of mothers of ADHD children, the results of the present study are in agreement with those of the previous ones. Meftagh and colleagues carried out a research on 95 mothers to determine the effectiveness of different treatment methods for children with ADHD on maternal mental health. That study indicated that maternal behavioral training methods and the medications used for these children improved maternal mental health in post-test and follow-up stages (
24). Moreover, Parand and colleagues performed a study which aimed to develop a stress management program for mothers of the children with ADHD and determine its effectiveness in their mental health. The results revealed significant improvement in mental wellbeing of the mothers and diminishing their anxiety and depression (
19).
The findings of the current study showed a reduction in stress levels in the placebo group immediately and one month after the intervention. The observed reduction might have resulted from participation in the meetings for talking about and expression of feelings. In addition, the loss rate in the placebo group was higher compared to the other two groups since they believed that expressing their feelings would not lead to any improvement. In the control group, no significant changes were observed regarding mental health and stress, anxiety and depression.
5.1. Limitation
This study had some limitations. First of all, the sample size was relatively small because of inclusion of three groups and lack of facilities. Thus, further studies with three groups and larger sample size are required to confirm the results of this study. Also, the studies are suggested to have follow-up periods of more than 1 month and be repeated over time.
The findings of the present study showed the effectiveness of cognitive behavioral stress management intervention in improvement of the mothers' mental health and stress.
Nonetheless, further studies with longer follow-up periods and in the mothers who have more than one ADHD child are suggested to be done in this area.
