Quieting response training: predictors of long-term outcome
Biofeedback and Self-Regulation
|September 1, 1983
Summary
Predicting outcomes for Quieting Response (QR) training proved challenging, as successful and unsuccessful patients showed more similarities than differences. Elevated psychological stress was noted in unsuccessful patients.
Area of Science:
- Psychology
- Behavioral Medicine
- Psychophysiology
Background:
- The Quieting Response (QR) is an 8-week training program integrating biofeedback and relaxation.
- Understanding predictors of treatment success is crucial for patient stratification.
Purpose of the Study:
- To identify patterns discriminating successful from unsuccessful outcomes in QR training.
- To evaluate the predictive power of personality, demographic, and symptom data.
Main Methods:
- Analysis of extensive patient data (personality, demographics, symptoms) from over 300 individuals.
- Stepwise discriminant analyses to identify predictive factors.
- Follow-up evaluations at 3, 6, 12, and 24 months post-training.
Main Results:
- Discriminant analysis achieved 65% accuracy for the whole sample, 62% for headache, and 70% for Raynaud's patients.
- Unsuccessful patients exhibited significantly elevated scores on MMPI scales D, Sc, F, Hy, and Pt.
- Unsuccessful patients generally reported higher psychological stress levels.
Conclusions:
- While some factors like psychological stress differentiated groups, patterns were more similar than dissimilar.
- No combination of factors provided sufficient predictive power for reliable outcome prediction.
- No statistical grounds for excluding patients based on response patterns were found.
