    This study refined the Diabetes Family Behavior Scale (DFBS) for measuring family support in pediatric diabetes. Higher family support scores correlated with better metabolic control (HbA1c) in youth with insulin-dependent diabetes mellitus.

    Area of Science:

    • Endocrinology
    • Pediatrics
    • Psychology

    Background:

    • Family support is crucial for managing chronic conditions like diabetes in children.
    • Existing measures may not fully capture diabetes-specific family dynamics.
    • The Diabetes Family Behavior Scale (DFBS) was initially developed to assess this support.

    Purpose of the Study:

    • To refine the Diabetes Family Behavior Scale (DFBS).
    • To evaluate the scale's reliability and criterion validity.
    • To examine the relationship between family support and metabolic control in pediatric diabetes.

    Main Methods:

    • The revised DFBS, with 47 items and two subscales (guidance-control, warmth-caring), was administered to 321 children and adolescents with insulin-dependent diabetes mellitus (IDDM).

  • Glycosylated hemoglobin (HbA1c) levels were measured to assess metabolic control.
  • Item analysis was used for scale refinement, and reliability (internal consistency) and validity were assessed.

    • Main Results:

    • The refined DFBS demonstrated acceptable internal consistency for the total score (.86) and subscales (.81 for guidance-control, .79 for warmth-caring).
    • A significant inverse relationship was found between the DFBS total score and HbA1c (r = -.12, P < .03).
    • The guidance-control subscale also showed a significant inverse relationship with HbA1c (r = -.17, P < .002).

    Conclusions:

    • The refined DFBS is a reliable and valid measure of diabetes-specific family support in youth.
    • Greater perceived family support, particularly guidance-control, is associated with better metabolic control in children and adolescents with IDDM.
    • The DFBS can be a valuable tool for assessing family dynamics impacting diabetes management in pediatric populations.
