Improved Items for Estimating SF-36 Profile and Summary Component Scores
BACKGROUND: Comprehensive health-related quality of life (QOL) assessment under severe respondent burden constraints requires improved single-item scales for frequently surveyed domains. This article documents how new single-item-per-domain (SIPD) QOL General (QGEN-8) measures were constructed for domains common to SF-36 and results from the first psychometric tests comparing scores for the new measure in relation to those for the SF-36 profile a…
The validity of single-item measures of health-related quality of life across groups differing in acute respiratory symptom severity
QGEN-8 ® shows satisfactory validity and warrants further testing in cross-sectional and longitudinal population and clinical survey research as a more practical method for estimating group differences in SF-36 profile and summary component HRQOL scores
The effects of greater frequency of two most prevalent bothersome acute respiratory symptoms on health-related quality of life in the 2020 US general population
Declines in HRQOL with acute cough and sore throat symptoms consistently exceeded MID standards and should not be ignored as self-limiting without intervention. Future studies on early self-care for symptom relief and its implications on HRQOL and health economics would be valuable to understand the benefits on healthcare burden and need for updating treatment guidelines

Developing a New Version of the SF-6D Health State Classification System From the SF-36v2
OBJECTIVE: The objective of this study was to develop the classification system for version of the SF-6D (SF-6Dv2) from the SF-36v2. SF-6Dv2 is an improved version of SF-6D, one of the most widely used generic measures of health for the calculation of quality-adjusted life years. STUDY DESIGN AND SETTING: A 3-step process was undertaken to generate a new classification system: (1) factor analysis to establish dimensionality; (2) Rasch analysis to…

Computerized Adaptive Testing—Ready for Ambulatory Monitoring
Background Computerized adaptive tests (CATs) have abundant theoretical advantages over established static instruments, which could improve ambulatory monitoring of patient-reported outcomes (PROs). However, an empirical demonstration of their practical benefits is warranted. Methods We reviewed the literature and evaluated existing data to discuss the potential of CATs for use in ambulatory monitoring outside clinical facilities. Results Compute…

Choosing measures of health status for individuals in general populations
This paper offers suggestions to adi the selection of appropriate instruments and data gathering methods for studies that require measures of personal health status applicable in general populations. Before selecting measures, the reason for studying health status must be identified. Next, definitional issues arise when attempting to specify the components of health that are to be studied. Evidence supports restriction of the definition of person…

An Extended Visit with Dr. Fox
Equivalent groups viewed two lectures varying in substantive teaching points covered (high, medium, low) and expressiveness of the presentation (high, low). Students rated lecture effectiveness after each lecture and completed an achievement test after the two lectures. Higher achievement was associated with high content coverage and high expressiveness. Students gave higher ratings to expressive lectures. Student satisfaction ratings reflected r…
Dimensions of Patient Attitudes Regarding Doctors and Medical Care Services
The factor analytic development and validation of numerous index scores to measure patient attitudes regarding characteristics of doctors and medical care services is described. Index scores meeting factor analytic criteria and found to be reliable were used to study the nature and number of attitudinal dimensions underlying patient satisfaction. The use of index scores which have met logical and empirical criteria is in contrast to the common pr…
Discriminant Analysis of Student Ratings as a Means for Identifying Lecturers who Differ in Enthusiasm or Information-Giving
This investigation employed discriminant analysis to improve the usefulness of student-faculty ratings in detecting differences in lecturer types. Equivalent groups of college students in each of two studies viewed lectures delivered by a Hollywood actor so as to vary in number of substantive teaching points covered (high, low) and presentation manner (enthusiastic, unenthusiastic). Students rated lecturer effectiveness using an 18-item questionn…
The Meaning of Health
Results of psychometric studies of 14 questionnaire items commonly used to define chronic functional limitations due to poor health are reported. Self-administered questionnaires were used to gather data from 1,209 persons 14 years of age and older. Data were used to study: scalability of items; test-retest reliability of alternate forms of scales; validity of scales in relation to 13 health status variables and age; and precision of scales in de…

Effects of Acquiescent Response Set on Patient Satisfaction Ratings
This paper summarizes the results of three studies of bias in patient satisfaction questionnaires due to acquiescent response set (ARS), a tendency to agree with statements of opinion regardless of content. Three independent surveys (N = 1,280) were fielded using the Patient Satisfaction Questionnaire. Across the three field tests, 40 to 60 per cent of respondents manifested some degree of ARS and from 2 to 10 per cent demonstrated noteworthy ARS…
Measuring Components of Childrenʼs Health Status
Measures of physical, mental and social components of health status and general health ratings were studied for children ages 0-4 (N = 679) and 5-13 (N = 1473). Questionnaires were completed by adult proxies (usually mothers) in three generally healthy populations. Hypothesized multi-item scales were tested; reliability was estimated and preliminary attempts at validation were undertaken. Items in ten scales pertaining to mental health (Anxiety, …
Factors Associated with Relief from Chest Pain Following Emergency- Care
A preliminary study was conducted to explore a range of factors that may be associated with relief from chest pain. Nonhospitalized ambulatory patients (N = 150) were interviewed in their homes shortly after seeking care at one of two hospital emergency rooms. Bivariate and multivariate analyses identified four factors positively correlated with symptom relief: whether someone accompanied the patient to the emergency room; whether the patient fea…

Advances in the Measurement of Functional Status
This article summarizes tests of the appropriateness of aggregating specific categories of physical capacities and limitations into aggregate functional status indexes. Self-administered questionnaires were used to gather data from 4,603 people between 14 and 66 years of age. Cumulative indexes defining ranked levels of functional status were derived for two global constructs of functioning (personal and role functioning). Each index is scored to…
How Sophisticated Are Consumers About the Medical Care Delivery System
A 10-item questionnaire was administered to non-elderly persons (N = 4,976) to measure their sophistication or knowledgeability about the medical care delivery system. Such sophistication seems germane to views about the appropriate role consumers might play in decisions affecting resource allocation, especially whether competition or cost-sharing strategies should be pursued or whether certain regulatory strategies are more promising. Analyses o…

Effects of Physical and Mental Health on Health-State Preferences
Studies concerned with measuring values and preferences for health states and health status components have typically employed "direct" scaling techniques that require conclusions to be based on definition. Problems and limitations of direct scaling are discussed. The algebraic modeling approach is new to health services research; it emphasizes testing models of how respondents combine stimulus information. The model specifies the causal relation…
Does Free Care Improve Adults' Health?
Does free medical care lead to better health than insurance plans that require the patient to shoulder part of the cost? In an effort to answer this question, we studied 3958 people between the ages of 14 and 61 who were free of disability that precluded work and had been randomly assigned to a set of insurance plans for three or five years. One plan provided free care; the others required enrollees to pay a share of their medical bills. As previ…

Patient Satisfaction and Change in Medical Care Provider
Longitudinal data from The Rand Corporation's Health Insurance Experiment were used to test the hypothesis that provider continuity can be modeled as one behavioral consequence of patient satisfaction. Bivariate and multivariate analyses (controlling for sociodemographic characteristics, prior use of services, health status, and health insurance plan) supported our hypotheses. A multivariate linear probability function indicated that a 1-point de…

Health status and the use of outpatient mental health services
Using data from the RAND Corporation's Health Insurance Study, the authors have linked mental health status (self-reported psychological distress and psychological well-being) to the subsequent use outpatient mental health services delivered by formally trained mental health specialists and general medical providers
Cost sharing and the use of ambulatory mental health services
Used preliminary data from the Rand Corporation's Health Insurance Study to examine expenditures for ambulatory mental health services (MHSs) based on a sample of 4,444 families (at initial enrollment) of the nonelderly, noninstitutionalized civilian population. Selected findings reveal that reducing the level of cost sharing increases the demand for MHSs; the response to cost sharing is roughly the same for ambulatory medical and MHSs
Physicians?? Practices in Counseling Patients About Health Habits
The authors developed and tested a model of two dimensions of physicians' behavior in counseling patients about four health habits (smoking, weight control, alcohol consumption, and regular exercise). The two dimensions are the indications for routine counseling and the aggressiveness of counseling style. To test these dimensions, a questionnaire was administered to a random sample of members of a Western County Medical Society in 1978. The respo…
Physicians?? Attitudes in Counseling Patients About Smoking
Attitudes of physicians toward counseling patients about their smoking habits may influence whether and how counseling occurs. In this paper, the authors develop and test a conceptual model of these attitudes. The model includes four attitude dimensions: physicians' motivations to counsel, perceived health risk of smoking, perceived skills in counseling, and perceived costs and benefits to the physician of counseling. A self-report questionnaire …
The Sensitivity of Mental Health Care Use and Cost Estimates to Methods Effects
The authors determined the sensitivity of estimates of the use and cost of outpatient mental health care to two methods effects: the definition of a mental health visit and strategies for allocating mental health care costs. They use data from the Rand Health Insurance Study, which has a random sample of the nonaged noninstitutionalized civilian population in six United States sites. Estimates of the use of mental health specialists are insensiti…
Expanding Patient Involvement in Care
An intervention was developed to increase patient involvement in care. Using a treatment algorithm as a guide, patients were helped to read their medical record and coached to ask questions and negotiate medical decisions with their physicians during a 20-minute session before their regularly scheduled visit. In a randomized controlled trial we compared this intervention with a standard educational session of equal length in a clinic for patients…
