Interpersonal stress and style as predictors of biofeedback/relaxation training outcome: preliminary findings.

Although the data base describing clinical outcome following biofeedback/relaxation training is accumulating, there have been relatively few attempts to predict short-term outcome, and even fewer for long-term outcome. Significant short-term outcome predictors have been identified, and they often allude to the level of psychological distress as a major factor affecting outcome. To investigate further the role of psychological variables in outcome prediction, this project presents preliminary findings that demonstrate the relationship involving interpersonal psychological stress, interpersonal style of behavior, and outcome. With a very heterogeneous group of patients (N = 39), measures of interpersonal style of behavior were used to discriminate correctly 80% of cases by outcome at the 3-month postadmission evaluation. With a more homogeneous group having somatic disorders alone (headache, Raynaud's, etc.), the accuracy of prediction at 3 months was 90%. No measures were capable of predicting long-term outcome with accuracies even moderately greater than chance. The results indicate that style of interpersonal behavior (e.g., managerial, dependent) and, to a lesser extent, interpersonal stress is predictive of short-term outcome following biofeedback/relaxation training. Individuals who tend to like responsibility and who are more executive and independent generally benefited more than doubtful, obedient, and depressed individuals. While the resulting prediction rates were only slightly more accurate than MMPI D and Pt subscales alone, the procedures provide additional information regarding the personality characteristics of successful and unsuccessful biofeedback clients, and may also provide the clinician with information regarding treatment choice if biofeedback is provided as an adjunct to psychotherapy.
