This article presents a comprehensive evaluation of the Pediatric Attention Disorders Diagnostic Screener (PADDS). PADDS was developed as a computer-based assessment system to screen for attention and executive function disorders in children aged 6 through 12 years. The evaluation of the PADDS indicated that it can be a useful and efficient instrument. It attempts to integrate parent and teacher ratings and three executive functioning tasks together to strengthen the diagnosis of attention-deficit hyperactivity disorder (ADHD). The strength of the PADDS is in having multiple sources of data in one system and being able to provide stepwise calculations of likelihood ratios. Thus, it is easy for the clinician to understand the cumulative effects, whether positive or negative. This tool exhibits potential for the field, though psychometric studies and analyses need to be completed to further establish its effectiveness and accuracy in the identification of children with ADHD.
