Bangla Strengths and Difficulties Questionnaire (Bangla SDQ)

Mohammad S I Mullick, Robert Goodman

Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh

Time: 5-10 minutes
Ages: 2-17 year olds
Time Frame: Last 6 months and above

Purpose: Screening emotional and behavioral problems of Bangladeshi children by researchers, clinicians and educationalists.

Commentary: The items cover emotional symptoms, conduct problems, hyperactivity, peer problems, and prosocial behaviors. A brief impact supplement asks whether the respondent thinks that he/she has a problem, and if so, inquires further about overall distress, social impairment, burden and chronicity. This provides useful additional information for clinicians and researchers with an interest in psychiatric caseness and the determinants of service use.

Versions: It exists in several Bangla versions of multi- source informants- parent, teacher and self.

Edition: First edition 2001, Second Edition 2017

Items: Bangla SDQ consists of 25 attributes as originally developed by Robert Goodman in English some of them are positive and some are negative.

Scale: These 25 items are divided between 5 scales:
1) emotional symptoms (5 items)
2) conduct problems (5 items)
3) hyperactivity/inattention (5 items)
4) peer relationship problems (5 items)
5) prosocial behaviour (5 items)

1) to 4) added together to generate a total score (based on 20 items)

Scoring: The 25 items in the SDQ comprise 5 scales of 5 items each. It is usually easiest to score all 5 scales first before working out the total difficulties score. ‘Somewhat True’ is always scored as 1, but the scoring of ‘Not True’ and ‘Certainly True’ varies with the item, as shown below scale by scale.
Interpretations: Subjects were considered as screen positive when they were found ‘probable’ psychiatric cases from Bangla SDQ cut-offs algorithm. It is simple paper and pencil method. SDQ cut-offs of total scale and sub scales are available.
Reliability and Validity: The SDQ has been shown to be of excellent reliability and validity in numerous studies. The SDQ has a good sensitivity (90%) and specificity (94%). Internal consistency of the SDQ,Total Difficulties Score and subscale scores are very good.
