2 * Norm-referenced checklist measuring symptoms of ADHD * Measures both inattentive and hyperactive-impulsive type * Home and school version * 18-item questionnaire using a Likert Scale * Approximately 5 minutes to complete * The purpose…. * Means of gathering data regarding frequency of behaviors from teachers and parents * Used by clinicians to screen, diagnose, or evaluate treatment of ADHD

3 * Created in 1998 by George J. DuPaul, Thomas J. Power, Arthur D. Anastopoulos, and Robert Reid * Unlike other ADHD measurements, the ADHD Rater Scale-IV provides clinicians with parent AND teacher ratings using DSM-IV guidelines * Developed using a 4-point Likert Scale method * Each scale item represents a symptoms described by the DSM-IV, without the use of “often”

4 * Ages 4-20 * Any ethnicity or sex * Versions for parents and teachers * Parent version is available in Spanish * Administration of both types is preferable

5 School Version: * Participants ranged from ages 4-19 years in age * Most children attended general education vs. special education (1816 to 161) * Participants were identified as living in one of four regions of the US (Midwest, Northeast, West, Northeast) * Racial distribution was Caucasian, African-American, Latino, Asian-American, and Native American Home Version * Participants ranged from ages 4-19 years in age * Participants were identified as living in one of four regions of the US (Midwest, Northeast, West, Northeast) * Racial distribution was Caucasian, African-American, Latino, Asian-American, and Native American * Parents respondents identified themselves as Caucasian, African-American, Latino, Asian-American, and Native American * Families were primarily living in middle-class socioeconomic status * Parent respondents were 1,753 female and 244 male

6 * The reliability and validity of the Home and School versions of the ADHD Rating Scale-IV were evaluated * Results indicated adequate levels of internal consistency, test-retest reliability, and cross-informant agreement for both parent and teacher ratings. * Discriminate validity-results found that both Home and School versions of ADHD Rating Scale-IV were found to discriminate significantly between children with and without ADHD. * Further the ADHD Rating Scale-IV can be used to differentiate between children with ADHD from other clinic-referred children as well as differentiate among the combined and inattentive subtypes of ADHD * Additional research is needed to verify the generalizability of the properties and utility of this scale across geographic regions, ethnic groups and socioeconomic groups.

7 * Results are described in terms of the Inattention and Hyperactivity- Impulsivity subscales, the total score, and percentile ranks for each score. * The Inattention subscale is scored by summing the responses on all the odd-numbered items (Items 1, 3, 5, 7, 9, 11, 13, 15, 17). * The Hyperactivity-Impulsivity subscale is scored by summing the responses on all the even-numbered items (Items 2, 4, 6, 8, 10, 12, 14, 16, 18). * Using the child’s gender and age (and the appendix), raw scores are converted to percentile scores. * If an item on the rating scale is missed, the respondent should be directed to provide an answer. If 3 or more items are skipped by the respondent, extreme caution should be used in interpreting the scale for any of the intended purposes.

8 * Diagnosing ADHD/I- * Inattention subscale (teacher) ≥ 90 th percentile * Inattention subscale (parent) ≥ 93 rd percentile * Hyperactivity-Impulsivity subscale (teacher) ≤ 85 th percentile * Ruling out ADHD/I * Inattention subscale (teacher) < 80 th percentile * Inattention subscale (parent) < 85 th percentile * Diagnosing ADHD/COM * Inattention subscale (teacher) ≥ 90 th percentile * Inattention subscale (parent) ≥ 93 rd percentile * Hyperactivity-Impulsivity subscale (teacher) ≥ 98 th percentile * Ruling our ADHD/COM * Inattention subscale (teacher) < 80 th percentile * Inattention subscale (parent) < 85 th percentile * Hyperactivity-Impulsivity subscale (teacher) < 85 th percentile

9 * Strengths: -based on the DSM-IV -completed in 5 minutes -sound psychometric features -can be used with other assessments -normative sample closely matches census data * Weaknesses: -data was not provided separately for ethnic groups -over diagnosis in African-American boys -more research needs to be done to determine the best use in all multi-cultural groups as well as the difference in setting between the scales

10 * Addwarehouse.com $55.00 * Includes teacher and parent report with permission to copy as many times as needed * Must fill out a “Qualification Form” from the website (in accordance with the ethical and professional standards of the American Psychological Association and the Standards for Educational and Psychological Testing) before being eligible to purchase the test * Purchasers of this type of test must have completed graduate level courses in tests/measurement or have received equivalent documented training.

11 * The purpose of this scale is to provide clinicians with a means of gathering information regarding the frequency of certain behaviors from teachers and parents. This information may be used by clinicians to assist in screening, diagnoses, or evaluation for the treatment of ADHD. * Quick and easy way to gather more information from important stakeholders invested in the child’s education and well-being. * Treatment and intervention can begin as soon as the results are available after the first session * Allows parents to take an active role in child’s education
