Parent-Reported mental health in nearest age siblings of children with Dravet Syndrome in Sweden

Purpose

To assess parent-reported mental health in nearest age siblings of children with Dravet Syndrome (DS).

Methods

In this observational study parents of 31 children (age 3–16 years; 18 males and 13 females) of nearest age siblings of children with DS completed the SDQ (Strength and Difficulties Questionnaire). Mental health level was determined using validated norms; abnormal ≥ 90 percentile/borderline ≥80 percentile. At risk status was considered borderline/abnormal. Data were analysed using descriptives and linear regression. Significance level was p < 0.05.

Results

Only five siblings (16 %) had elevated scores on the SDQ total score. However, 32 % of siblings had difficulties on the Emotional subscale and 26 % on the Peer subscale. Only one child (3 %) had an elevated score on the Prosocial subscale which indicates strengths. Regression analysis did not find any significant associations with the SDQ total score.

Conclusions

Siblings of children with DS would not appear to have a higher risk of mental health problems but specific supports may be needed regarding emotional problems. More research is needed to better understand the sibling experience in children with DS and other Developmental and Epileptic Encephalopathies.
