Investigated whether heart rate biofeedback training is as effective as muscular relaxation training in reducing speech anxiety. A combined muscle relaxation/biofeedback treatment group was also included in this study. All treatment groups were compared to a false-biofeedback placebo control group. This investigation also assessed whether the degree of autonomic nervous system awareness significantly influences the treatment process. 10 speech-anxious undergraduate Ss, high and low scorers on the Autonomic Perception Questionnaire, were assigned to each group. Results indicate that all 4 groups demonstrated a decrease in self-reported anxiety. Assessment of physiological measures (heart rate and skin conductance) indicated that the 3 treatment groups were associated with less physiological responding during the posttreatment assessment of anxiety, relative to the false-biofeedback group. Moreover, among the 3 treatment groups, the combined relaxation/biofeedback group demonstrated the lowest level of responding. The degree of autonomic awareness was not related to therapeutic improvement. (12 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
