Introduction and Purpose: The behavioral activation/inhibition System and the family health climate are among the important factors influencing diabetes management. This study aimed to investigate the mediating role of procrastination in the relationship between behavioral activation/inhibition systems and family health climate in families with type 2 diabetes patients.
Methods: This was a correlational analytical study using structural equation modeling. A total of 220 patients with type 2 diabetes in Shahin Shahr, Isfahan, were recruited using convenience sampling. Data were collected using the Family Health Climate Questionnaire, the Tuckman Procrastination Scale, and the Carver and White’s Behavioral Inhibition/Activation Systems Questionnaire. Data analysis was conducted using structural equation modeling in AMOS.
Results: The results showed that behavioral inhibition had a significant negative direct effect on procrastination (β=-0.11, P<0.05) and a significant positive direct effect on family health climate (β=0.16, P<0.05). Behavioral activation had a significant positive direct effect on procrastination (β=0.23, P<0.05). Procrastination, in turn, had a significant negative direct effect on family health climate (β=-0.29, P<0.05). The indirect effect of the behavioral inhibition subscale on procrastination was also significant; however, the behavioral activation systems had no direct effect on family health climate.
Conclusion: The behavioral inhibition system plays a supportive role in the family environment by reducing procrastination and directly improving the family health climate. In contrast, behavioral activation may indirectly contribute to tension in the family climate by increasing procrastination. Therefore, psychological interventions for families affected by type 2 diabetes should not focus solely on medical education. They should also aim to reduce procrastination and strengthen sensitivity to negative consequences, thereby more effectively promoting a supportive and emotionally healthy family climate.
