The vailidation of the self-report Strengths and Difficulties Questionnaire for use by 6-to 10-year-old children in the UK

Abstract

Objective
To examine the factor structure of the self-report Strengths and Difficulties Questionnaire (SDQ) for data from a sample of British children aged 6–10 years.

Method
The self-report SDQ was administered to 900 children aged 6–10 years via interviews with trained counsellors.

Results
Confirmatory and exploratory factor analyses showed that a two-factor solution comprising ‘externalizing and peer problems’ and ‘internalizing problems’ fit the data well for both the 6- to 7- and 8- to 10-year-old samples. The factors were correlated in both samples.

Conclusions
Children between 6 and 10 years of age provided meaningful SDQ data. The identified two-factor model maps broadly onto the constructs of externalizing and internalizing behaviour.
