Since the questionnaire relies on client self-report, all responses should be verified by the clinician, and a definitive diagnosis is made on clinical grounds taking into account how well the client understood the questionnaire, as well as other relevant information from the client.
Psychometric properties: The CRBS was developed on a large sample of adults (N = 453) residing across the United States. The CRBS is a reliable instrument (α = .90), with solid factorial (single-factor) and construct (correlated with dysfunctional coronavirus anxiety, generalized anxiety, depression, and health anxiety) validity.
Scoring and interpretation: Each item of the CRBS is rated on a 5-point scale, ranging from 0 (not at all) to 4 (nearly every day), based on experiences over the past 2 weeks. This scaling format is consistent with the DSM-5’s cross-cutting symptom measure. Severity scores are obtained by summing responses to all items, with total scores (M = 6.23; SD = 5.51) ranging from 0 to 20. Although clinical cut-off scores have not yet been determined, CRBS total scores ≥ 12 suggest above average reassurance-seeking activity. Clinical judgement should guide the interpretation of the CRBS results.
