Psychometric properties of the SDQ hyperactivity subscale in a Transylvanian minority community sample. A pilot study

In the current study the SDQ was used as an ADHD screening tool. The main aim was to examine the psychometric properties: reliability and validity of the Hungarian version of SDQ hyperactivity subscale. In a Transylvanian community sample, a Hungarian minority group of 42 children in Romania (N=42), aged between 5-11 years, parents and teachers filled out the SDQ, CBCL/TRF, ADHD-RS-IV. The internal consistency of the SDQ teacher and parent version was α=.91, respectively α=.83. Cronbach's alpha results indicate high reliability for all questionnaires (hyperactivity subscale) used, values ranging between α=.75 .97, the highest values were obtained from ADHD-RS-IV. Test-retest correlations were r=.72-.97, showing good predictive validity. The concurrent validity of SDQ was r=.85-.95. The parent-teacher inter-rater reliability was medium for SDQ [ICC, Absolute agreement] (2,1)=.56 (95%CI: .45-.69). Psychometric properties of the SDQ hyperactivity subscale are consistent with the previous international studies, results are generally satisfactory with acceptable values.
