An explanatory model of adjustment to type I diabetes based on attachment, coping, and self-regulation theories.

The aim of this study was to develop and test a model of adjustment to type I diabetes. Three hundred young adults (172 females and 128 males) with type I diabetes were asked to complete the Adult Attachment Inventory (AAI), the Brief Illness Perception Questionnaire (Brief IPQ), Task-oriented subscale of the Coping Inventory for Stressful Situations (CISS), D-39, and well-being subscale of the Mental Health Inventory (MHI). HbA1c was obtained from laboratory examination. Results from structural equation analysis partly supported the hypothesized model. Secure and avoidant attachment styles were found to have effects on illness perception, ambivalent attachment style did not have significant effect on illness perception. Three attachment styles had significant effect on task-oriented coping strategy. Avoidant attachment had negative direct effect on adjustment too. Regression effects of illness perception and task-oriented coping strategy on adjustment were positive. Therefore, positive illness perception and more usage of task-oriented coping strategy predict better adjustment to diabetes. So, the results confirmed the theoretical bases and empirical evidence of effectiveness of attachment styles in adjustment to chronic disease and can be helpful in devising preventive policies, determining high-risk maladjusted patients, and planning special psychological treatment.
