Does the Format of the Adult ADHD Self-Report Scale Impact the Results

The World Health Organization Adult ADHD Self-Report Scale v1.1 (ASRS) is frequently used in family medicine clinics to screen for ADHD. Numerous studies have found the ASRS has a low positive predictive value. Compounding this concern is the format of the ASRS. Specifically, the answers on the ASRS that lead to screen positive results are shaded in gray and grouped together, which may make it easy for patients to discern which responses should be selected for a positive screen.

About this study

The ASRS is used widely to screen for ADHD in adults. It has 18 questions, with response options "never," "rarely," "sometimes," "often," and "very often." The 6 questions considered most predictive of ADHD are grouped together in Part A and questions that are meant to provide additional cues are grouped together in Part B. The options that are considered a positive response vary between questions; for some questions the option is at least "sometimes," while for others it is at least "often." The positive response options are shaded on the ASRS. A person is considered to have a positive screen if 4 of the 6 questions in Part A are positive.

The objective of this trial is to determine if the shading and grouping on the ASRS impacts screening results. This trial has a 2x2 factorial design set in a family medicine clinic(s). When a patients check in for an appointment, clinic staff will offer them a survey that includes 1) demographic questions and 2) 1 of the 4 versions of the ASRS, the version they receive is randomized (with programming). Most patients will take approximately 5 minutes to complete the survey prior to them seeing the family physician.

Primary outcomes

  1. Screen positive rate

    Time frame: Through study completion, estimated to be 2 months

    Poisson regression to determine the relative risk of a screen positive among the different versions of the form. We will include the following covariates: shading, grouping, shading x grouping, suspect ADHD without diagnosis, ADHD diagnosis, sex, and age.
