title: Maximization of biofeedback following cognitive stress preselection in generalized anxiety.
abstract: 53 subjects, who scored high on an anxiety check list, were evaluated for their responsiveness to relaxation exercises and biofeedback. Each subject was cognitively stressed prior to the training phase by imagining anxiety-provoking situations. Analysis was done on pertaining/posttraining anxiety scores and physiological parameters (galvanic skin response, differences in finger temperature, and frontalis muscle activity). Subjects given feedback corresponding to that physiological parameter which changed the most when stressed, maximized that feedback more than subjects receiving nonrelevant or no feedback. All groups reported significant reductions in anxiety symptoms. Follow-up analysis 15 mo. later showed 76% of the subjects were still symptom-free for anxiety regardless of type of feedback received.
