Middle school students' willingness to engage in activities with peers with ADHD symptoms: a multiple indicators multiple causes (MIMIC) model.

Researchers examining peers' behavioral intentions toward students diagnosed with ADHD have frequently used vignettes and asked students to indicate their willingness to engage with an individual described either with or without symptoms of ADHD. The Shared Activities Questionnaire (SAQ-B) is one instrument that has been used to measure students' intentions to engage with students represented in these vignettes. Confirmatory factor analysis results from 183 middle school students supported the three-factor model underlying the SAQ-B, although there were some areas of model misfit.
