Treatment of paruresis with in vivo desensitization: a case report.

In vivo desensitization was employed with a patient exhibiting chronic paruresis. Measures of urination delay, and subjective units of distress were obtained at pre-training, during training, at a generalization trial, and at a follow-up assessment. Urine volume was also measured at pre- and post-training. There was shorter delay in urination, greater urine output, and less subjective anxiety following treatment. These effects were also demonstrated during a generalization post-test in which the patient was exposed to an unknown observer. A follow-up trial involving exposure to a second unknown observer indicated that treatment effects were maintained at 7.5 months following treatment.
