The Role of Systemic Family Psychotherapy in Glycemic Control for Children with Type 1 Diabetes

(1) Background: Family factors play an important role in the management of diabetes, establishing a relationship between conflicts and non-adherence to therapy. High values of HbA1c are involved in specific complications of the disease (retinopathy, nephropathy, neuropathy, ketoacidosis). This study aimed to determine the role of systemic family psychotherapeutic interventions in increasing the quality of parent–child/adolescent relationships and in optimizing the child’s glycemic control. (2) Methods: In this prospective observational study, 64 parents of children and adolescents with type 1 diabetes were evaluated regarding their relationship with their children, using the Child–Parent Relationship Scale-Short Form (CPRS-short form). The children were divided into three groups: one participated for 6 months in systemic family psychotherapy with children and their parents (FT), the second group participated in individual psychotherapy (IT), and the control group (CG) received no intervention. HbA1c values were recorded before and after the interventions. (3) Results: HbA1c means decreased significantly after the family psychotherapy program. The scores on closeness in the family therapy group increased significantly, and the scores on conflict decreased significantly after the intervention, compared with IT and CG. (4) Conclusions: Systemic family psychotherapy produces better results in disease management and in strengthening parent–child relationships.
