The USA-USSR collaborative cross-cultural comparison of autogenic training and thermal biofeedback in the treatment of mild hypertension

Abstract

We have conducted a cross-cultural (USA and USSR) comparison of thermal biofeedback (TBF) and autogenic training (AT) to a self-relaxation control condition in 59 unmedicated males with mild hypertension. Identical assessment and treatment protocols were carried out in both settings (Albany, New York, and Moscow). Treatments were delivered in small groups on an outpatient basis twice per week for 10 weeks. Results showed comparable, significant (p less than .05), short-term decreases (M = 8.5 mm Hg) in diastolic blood pressure (DBP) for both treatments at both sites. However, the Soviet patients, starting with significantly (p less than .01) higher systolic blood pressures (SBPs), showed significant decreases (M = 12.8 mm Hg) in SBP, whereas the American patients did not change appreciably (M = 4.6 mm Hg). During follow-up, the treated Soviet patients showed significantly (p less than .05) better maintenance of treatment effects, from 3 months to 1 year, than did the American patients. At 1 year, 75% of the treated Soviet patients had DBPs less than 90 mm Hg, whereas only 24% of the American patients had comparable DBPs.
