Description:
|
The authors purport that the quality of outcome instruments has declined. They felt a need for comprehensive and cost-effective ways to measure outcomes. Therefore, this book provides self-administered scales with strong psychometric properties to measure health behavior, health status, self-efficacy, and health care utilization. Most of the scales in the book were developed by the authors through the Stanford Patient Education Research Center, to be used in the Chronic Disease Self-Management Study. There are some previously published scales available in this book, but the bulk of scales stem from the authors’ own research. Most of the scales have not been published, thus the authors explain their development in detail. The authors use a self-efficacy theory of disease management; therefore, many of the scales focus on a person’s self-efficacy to perform various functions.
Chapter 1 explains the rationale for the Chronic Disease Self-Management instruments, while Chapter 2 gives psychometric information for each. Appendices B through E contain published scales from other sources.
Appendix B contains the SF-36 and Illness Intrusiveness Ratings Scale.
Appendix C contains measures of individual health constructs and includes: General Health Visual Analogue Scale, Self-Rated Health, Qualify of Life Visual Analogue Scale, Health Assessment Questionnaire Disability section, Multidimensional Assessment of Fatigue, Fatigue Visual Analogue Scale, Gracely Pain, Pain Visual Analogue Scale, and Center for Epidemiologic Studies Depression scale.
Appendix D contains measures of health behaviors and includes the Self-Reported Medication-Taking Scale and Coping Strategies Questionnaire.
Appendix E consists of two patient satisfaction scales, the Picker Ambulatory Care Patient Interview (sample questions only) and Group Health Association of America Consumer Satisfaction Survey.
Appendix F is a compendium of selected Spanish language scales, including the Self-Rated Health, MOS Pain Severity Scale, Pain Visual Analogue Scale, Modified Visual Numeric Pain Scale, Health Assessment Questionnaire, Center for Epidemiologic Studies Depression scale, Arthritis Self-Efficacy, and Physical Activities.
