Background:Having a child with diabetes creates a great deal of stress for mothers. The transactional model of stress and coping is one of the best conceptual frameworks for stressors. Objectives: This study aimed to investigate factors related to health promoting behaviors based on transactional model in mothers of children with type 1 diabetes. Methods: This study was conducted on 180 mothers of children with type 1 diabetes. The data was collected using a multi-sectional questionnaire including demographic characteristics and questions about the model constructs. Data were analyzed by SPSS software (version 19) and using statistical tests. Results:The highest mean score was related to interpersonal relationships (13.8 ± 4.5) and the lowest was related to stress management (10.8 ± 4.2). Linear regression model showed that mother's education, information seeking, and social support had a positive effect, and primary appraisal and emotion-focused coping had a negative effect on the mother's health promotion behaviors. In the regression model R-square accounts for 53.7% of the variance. Conclusions: The transactional model was an appropriate framework for explaining the coping outcomes in mothers of children with type 1 diabetes. By mothers' attempts to improve attitude about diabetes and reduce their vulnerability, training to use coping strategies, increasing information and inter-sectoral interventions for attracting sufficient support from patients' families can be hopeful in improving mothers' behavioral Functioning.

Purpose Having a child with type 1 diabetes as a stressor causes the use of coping strategies in mothers. The aim of this study was to investigate the coping strategies in mothers of children with type 1 diabetes and their relationship with stress management. Methods This study was conducted on mothers of children with type 1 diabetes (N = 180) in Tehran and Karaj (Iran). Data were collected by a multi-sectional questionnaire that its validity and reliability were confirmed. Data were analyzed by SPSS software (v 19) and using statistical tests. Results The highest mean score was related to problem-focused coping (22.11) and the lowest was related to emotion-focused coping strategies (12.2). Regression model showed that the variables of mother's age, problem-focused coping, and meaningbased coping had a positive effect, and variables of father's age and emotion-focused coping had a negative effect on stress management in mothers. Conclusion Mothers of children with type 1 diabetes can be more successful in their stress management through using problemfocused and meaning-based coping approaches. Hence, the need for continuous education of effective coping strategies to these mothers is felt.
