The aim of the present study was to investigate the role of a clinical context in the experience of hypnotic age regression. Twenty-five patients experienced hypnotic age regression in an experimental and clinical context in counterbalanced order. Patients obtained significantly lower scores for experimental age regression than for clinical age regression, in particular when the experimental assessment preceded the clinical assessment of age regression. Moreover, scores for clinical and experimental age regression were only significantly and positively correlated when the clinical assessment of age regression preceded the experimental assessment. These findings give a tentative indication that more patients are able to experience clinical age regression than can be predicted from their responses to an experimental suggestion for hypnotic age regression where almost no opportunities for patient contact or maximizing of hypnotic responsiveness are provided.
