The ADHD Rating Scale-IV obtains parent ratings regarding the frequency of each ADHD symptom based on DSM-IV criteria. Parents are asked to determine symptomatic frequency that describes the child’s home behavior over the previous 6 months. The ADHD Rating Scale-IV is completed independently by the parent and scored by a clinician. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). If 3 or more items are skipped, the clinician should use extreme caution in interpreting the scale. Results from this rating scale alone should not be used to make a diagnosis.

The Eating Attitudes Test (EAT, EAT-26), created by David Garner, is a widely used self-report questionnaire 26-item standardized self-report measure of symptoms and concerns characteristic of eating disorders. The EAT has been a particularly useful screening tool to assess "eating disorder risk" in high school, college and other special risk samples such as athletes. Screening for eating disorders is based on the assumption that early identification can lead to earlier treatment, thereby reducing serious physical and psychological complications or even death. Furthermore, EAT has been extremely effective in screening for anorexia nervosa in many populations.
