Objective To characterize caregiver stress (CS) in parents of children with Eosinophilic Gastrointestinal Disorders (EGIDs) and understand relationships with psychological functioning and child behavior. Methods Caregivers with a child (0-17 years) with EGID completed questionnaires for demographics, EGID severity, treatments, CS, psychological distress, self-efficacy, and child behaviors. Results A total of 163 caregivers (98% mother, 94% Caucasian) participated. CS correlated with psychological distress, income, child behavioral problems, treatments, and disease severity. Children were rated higher than age-specific norms for emotional difficulties. Behavioral difficulties associated with gender, age, EGID severity, and duration. Parent psychological distress was most strongly associated with CS. Parental self-efficacy, dietary treatments, and child emotional difficulties were also related to stress. Conclusions Mothers reported stress and psychological distress from caring for a child with EGID. The relationship between these variables suggests these parents may benefit from supportive psychotherapy interventions. Evaluation of parental self-efficacy and child behavior is also warranted.
