Construct-related validity of the strengths and difficulties questionnaires with three and five dimensions: A multitrait-multimethod analysis
CLINICAL CHILD PSYCHOLOGY AND PSYCHIATRY(2023)
摘要
The Strengths and Difficulties Questionnaire (SDQ) is one of the most broadly used questionnaires to evaluate children's psychological adjustment, however its internal structure has been a target of ongoing controversy. Recent studies suggested a three-factor structure of the SDQ, however data is still scarce. The present study used the Multitrait-Multimethod analysis to examine SDQ construct related-validity with three and five dimensions, provided by children, their parents and teachers. A total of 415 participants were recruited from a Portuguese community sample. Both SDQ versions presented good convergence-related validity, with higher values for the five version. Findings from this study suggest that the SDQ with three dimensions could be more suitable as a screening measure of children's psychological adjustment in a community low-risk sample. Nevertheless, the SDQ still needs further psychometric improvements in order to properly collect information from multi-source samples about the prevalence of children's psychological adjustment.
