ACQ-SI Overview

Measure the extent of the difference between a person’s reported quality of social interaction and what you, the occupational therapist, observed. Use the ACQ-SI to extend the impact of the Evaluation of Social Interaction (ESI) in your occupation-centered practice.

  • Use with anyone over the age of 3 years, regardless of diagnosis
  • Learn the person’s perspective on his or her social interaction
  • Standardized on an international sample of more than 1,200 people
  • Watch an ACQ overview video

Administering the ACQ-SI

The ACQ-SI takes minutes to administer and score, resulting in a reliable and valid measure of the discrepancy between a person’s perspective on his or her quality of social interaction and what you, the occupational therapist, observed.
  1. Administer the ESI by observing a person engage in at least two real social exchanges with typical social partners
  2. Interview the person following your ESI observation using the ACQ-SI Interview Guide
  3. Score the ESI
  4. Score the 11 ACQ-SI items by comparing what the person reported during the interview with your ESI ratings
  5. Use the OTAP software to generate an ACQ-SI Results Report that includes an ACQ-SI discrepancy measure
  6. Plan interventions that account for the person’s perspective and the areas of discrepancy and/or agreement between what you observed and what the person reported
