Emotional and Behavioural disorders in a cohort with Down syndrome using the Strengths and Difficulties Questionnaire: A pilot study.

Background: Globally, mental health disorders and behavioural problems afflict persons with Down syndrome (DS) with a high prevalence reported in some studies. However, data on behavioural and emotional disorders in DS cohort in Asian countries are lacking.

Aims: To assess the mental health status of children and adults with DS, using the Strength and Difficulties Questionnaire (SDQ) and its impact on caregivers using the impact supplement.

Methods: The questionnaires were administered to caregivers of eligible participants aged ≥4 years. In addition, Down syndrome participant's ≥ 11 years old attempted the self-report. Scoring was done as per standard SDQ guidelines.

Results: The total difficulties score was observed to be at least borderline high in 30.6% (19/62) of the participants. Peer relationships and conduct subscale issues were rated high, with abnormal internalizing scores predominating over externalizing scores. From parents' perspective, behavioural issues impacted 41.9% (26/62) of participants' in areas of education, peer relationship and leisure. However, only 3.8% (1/26) of the caregivers whose children had behavioural issues perceived them as a burden.

Conclusions: Mental health difficulties are a significant morbidity in our DS cohort. SDQ is a useful user-friendly tool for identification of behavioural problems enabling timely referral for intervention and therapy.
