About This Profiling Tool

The Adult Repetitive Behaviours Questionnaire-2 (RBQ-2A) is an educational instrument designed to measure structural variables associated with restrictive and repetitive routines (RRBs).

This assessment organizes traits into 4 structural clusters: Motor Movements, Sensory Interest, Rigidity & Routines, and Restricted Interests. It utilizes a dichotomous scoring algorithm to generate a reliable data profile. The primary baseline threshold is 26 points out of 60.

Instructions: Answer based on your current and typical behavior patterns. All 20 items must be completed to generate an accurate profile.

Scoring Rule Architecture

Dichotomous capping logic applies: Responses are scored 1–3 points. The highest operational variable is capped at 3 points to prevent extreme structural distortion.

What Is the RBQ-2A? Educational Overview

The Adult Repetitive Behaviours Questionnaire-2 (RBQ-2A) is a validated educational assessment instrument established by Sarah L. Barrett and colleagues in 2015. It quantifies restricted and repetitive behaviors (RRBs). While many educational screeners focus heavily on social dynamics, the RBQ-2A isolates the structural RRB dimension, functioning as a valuable complement to broad-spectrum profiling tools.

Three Core Psychometric Domains

The RBQ-2A evaluates behavioral frequency across specific sub-domains. Repetitive Motor Behaviours includes physical kinetic patterns. Insistence on Sameness assesses reliance on routine predictability and structure. Restricted Interests tracks the specific intensity and focus on defined topics. The structural analysis of these variables aids in creating a comprehensive neurodivergent profile.

Frequently Asked Questions

What does the RBQ-2A actually measure?

The RBQ-2A establishes an educational baseline regarding restricted and repetitive behaviors (RRBs). It operates across structural domains: Repetitive Motor Behaviours, Insistence on Sameness, and Restricted Interests.

Should I use the RBQ-2A alongside the AQ-50 or RAADS-R?

Yes. The RBQ-2A specifically targets RRBs, whereas tools like the AQ-50 and RAADS-R map broader social and cognitive traits. Utilizing them collectively establishes a comprehensive educational profile.

How many items does the tool contain?

The RBQ-2A consists of 20 items requiring responses on a structural frequency scale. It generally requires 5 to 8 minutes to complete.
