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.
Elevated scores on a particular item or a high total scale score (≥ 7) may indicate problematic symptoms for the individual that might warrant further assessment and/or treatment. Clinical judgement should guide the interpretation of the OCS results.
Psychometric properties: The OCS was developed on two large samples of adults (n = 775; n = 398) residing across the United States. The OCS is a reliable instrument (αs > .83), with solid factorial (single-factor) and construct (correlated with coronavirus anxiety, spiritual crisis, alcohol/drug coping, extreme hopelessness, and suicidal ideation) validity. The diagnostic properties of the OCS (81% to 93% sensitivity and 73% to 76% specificity) are comparable to related screening instruments, such as the General Health Questionnaire (GHQ).
