Abstract
OBJECTIVES
To examine the psychometric properties of the Chinese version of Swanson, Nolan and Pelham IV Scale (SNAP-IV)-Teacher Form.
METHODS
The sample included a representative sample of 3,653 first to eighth graders (boys, 52.3%) and 190 children diagnosed with ADHD (aged 6-15). Teachers completed the Chinese versions of the SNAP-IV, and Strengths and Difficulties Questionnaire.
RESULTS
The confirmatory factor analysis revealed a four-factor structure (inattention, hyperactivity, impulsivity, and opposition) with an adequate fit (Comparative Fit Index = 0.990; root mean square error of approximation = 0.058). The test-retest reliability (intraclass correlations = 0.60-0.84), internal consistency (alpha = .88-.95), and concurrent validity (Pearson correlations = 0.61-0.84) were satisfactory. Children with both ADHD and oppositional defiant/conduct disorders had the highest scores, followed by children with ADHD only who had intermediate scores and then school-based participants who had the lowest scores.
CONCLUSIONS
Our findings suggest that the Chinese SNAP-IV-Teacher Form is a reliable and valid instrument for rating ADHD and oppositional symptoms (ClinicalTrials.Gov number, NCT00491361).
