Both the personal-model and barriers scales had good internal consistency and predicted variance in each of the self-management variables after controlling for demographic and medical history factors. These brief self-report personal-model scales demonstrated good internal reliability and were as predictive of self-management as the lengthier interview-based measures in previous studies. The assessment of the treatment effectiveness component of personal models may be sufficient for most clinical purposes.
