Adult Repetitive Behaviour Questionnaire-2 (RBQ-2A)
Select Language (google translate):
Type of Measure: The Adult Repetitive Behaviour Questionnaire-2 (RBQ-2A) is a 20-item self-report questionnaire that is based on items from the Diagnostic Interview for Social and Communication Disorders. The RBQ-2A measures restricted and repetitive behaviours such as routines and rituals, repetitive motor behaviours, sensory interests, and repetitive actions with objects. It is suitable for adults and only accessible to those with sufficient cognitive resources and verbal ability.
Target Population: Adults (18 years and older)
Measurement properties and previous use: The psychometric properties of this evaulation tool were examined among university students in the UK and adults in Australia (Barrett et al., 2015). Results from a Principle Components Analysis suggest a two-factor structure – motor behaviors (coefficient alpha = 0.79) and preference for for sameness (coefficient alpha = 0.83). The RBQ-2A is a relatively new measure, but the developers assert that the RBQ-2A is a useful self-report measure of repetitive and restrictive behaviors in adults and reportedly discriminates between adults with Autism Spectrum Disorder and neurotypical individuals.
