Siblings of children with type 1 diabetes mellitus: Psychosocial health, coping

The literature widely reported the psychosocial toll of Type 1 diabetes mellitus (T1DM) on patients, though the family functioning of T1DM patients, particularly siblings, has traditionally obtained far less consideration. This study was framed to investigate the psychosocial adjustments of siblings of children with T1DM and to evaluate the frequencies and the perceived efficacy of coping strategies adopted by siblings.

This cross-sectional study included parents (n = 100) and siblings (n = 100) of children with T1DM. Parents completed the following questionnaires: Parenting Stress Index-Short Form, Pediatric Quality of Life Inventory™ Family Impact Module, and Strengths and Difficulties Questionnaire (SDQ), while siblings completed SDQ self-report and kidcope questionnaires.

Thirty-eight percent of siblings of children with T1DM reported significant emotional and behavioral problems related to HbA1c level, higher parenting stress, and worse family functioning (p < 0.05). Younger siblings considered social support and distraction the most effective coping strategies, while older siblings perceived adaptive coping as the most effective. Social support and problem-solving were found to be protective factors for better sibling adjustments; meanwhile, better family adjustments were related to social support and cognitive restructuring (p < 0.05).

Results demonstrate that siblings of children with T1DM experienced psychosocial maladjustment. Sibling adjustments are family interrelated. Adaptive coping strategies may play a buffer role for siblings and family adjustment.

The study highlights the need for comprehensive evaluations of family dynamics and sibling psychosocial functioning to provide appropriate family-centered care.
