Studies by Baker and colleagues have shown a high reliability and validity to the self-report questionnaire, consistent with the clinician-administered version of the LSAS, with the only exception being the fear subscale of performance situations. All subscales measures show high test-retest reliability.
Baker's research indicates that the self-report questionnaire has a high level of reliability and validity, comparable to the clinician-administered version of the LSAS. The only exception is the fear subscale related to performance situations, which shows lower reliability. All other subscales demonstrate consistent high test-retest reliability.
