Cross-sectional data from the Medical Outcomes Study (MOS) were analyzed to test the validity of the MOS 36-Item Short-Form Health Survey (SF-36) scales as measures of physical and mental health constructs. [] Key Method Results from traditional psychometric and clinical tests of validity were compared. Principal components analysis was used to test for hypothesized physical and mental health dimensions.

Do differences in methods for constructing SF-36 physical and mental health summary measures change their associations with chronic medical conditions and utilization?

Differences between the two sets of summary scores were consistent with their respective conceptual and analytic approaches, and it was found that the SF-36 and RAND-36 summary scores generally yielded results similar to one another across measures of heart disease, diabetes, and kidney disease, as well as measures of utilization.

Comparison of methods for the scoring and statistical analysis of SF-36 health profile and summary measures: summary of results from the Medical Outcomes Study.

Results suggest that the two summary measures may be useful in most studies and that their empiric validity, relative to the best SF-36 scale, will depend on the application.

Reliability and Validity of the SF-12 Health Survey Among People With Severe Mental Illness

The SF-12 appears to be a psychometrically sound instrument for measuring health-related quality of life for people with SMI and was related to physical and mental health indexes in expected ways.

Differential Item Functioning in the SF-36 Physical Functioning and Mental Health Sub-Scales: A Population-Based Investigation in the Canadian Multicentre Osteoporosis Study

SF-36 PF and MH sub-scale scores were not comparable across population sub-groups defined by demographic and health status variables due to the effects of DIF, although the magnitude of this bias was not large for most items.

Health outcomes by self-report: validity of the SF-36 among Australian hospital patients

While the SF-36 performed satisfactorily, there were weaknesses: the social functioning scale was too narrow to cover social health, both role limitations scales had crude response categories and particular subgroups, the frail elderly and those with complex health conditions, required measures with finer gradings for scales such as physical functioning and bodily pain.

An empirical comparison of four generic health status measures. The Nottingham Health Profile, the Medical Outcomes Study 36-item Short-Form Health Survey, the COOP/WONCA charts, and the EuroQol instrument.

The SF-36 appeared to be the most suitable measure of health status in this relatively healthy population on the basis of the results of the psychometric analyses.

A Health Status Questionnaire Using 30 Items From The Medical Outcomes Study: Preliminary Validation in Persons With Early HIV Infection

A modified measure of human immunodeficiency virus-relevant items developed for the Medical Outcomes Study from subscales for cognitive function, energy/fatigue, health distress, and a single quality of life item were added to a portion of the MOS Short-form General Health Survey.

Multidimensionality of Health Status in an Elderly Population: Construct Validity of a Measurement Battery

Principal components analysis used to examine the relations among a set of health status measures gathered on 590 elderly members of a health maintenance organization (HMO) found patients' ratings of their overall physical and mental health were related to functional, physiologic, and emotional health factors, whereas physicians' ratings were never related to the emotional health factor.

The Medical Outcomes Study Instrument (MOSI)--use of a new health status measure in Britain.

The paper suggests that the MOSI may be a candidate for Health Status measurement in research and audit in primary care, but further research is required.

Measuring Functioning and Well-Being: The Medical Outcomes Study Approach

This book provides a set of ready-to-use generic measures that are applicable to all adults, including those well and chronically ill, as well as a methodological guide to collecting health data and constructing health measures.

The Impact of Psychologic Factors on Measurement of Functional Status: Assessment of the Sickness Impact Profile

The SIP discriminates psychosocial and physical dysfunction even in medical patients with extensive psychiatric comorbidity; the SIP measures at least two dimensions of health, one of which is strongly related to depression; and constructs measured by MMPI scales do not have substantial independent contribution to SIP variance.

The Sickness Impact Profile: Development and Final Revision of a Health Status Measure

The final development of the Sickness Impact Profile (SIP), a behaviorally based measure of health status, is presented and a technique for describing and assessing similarities and differences among groups was developed using profile and pattern analysis.

Comparison of the Duke Health Profile and the MOS Short-form in healthy young adults.

This study compares the length and conceptualization of the Medical Outcomes Study Short-form and the Duke Health Profile in a young and healthy group of medical students to help clinicians assess patient outcomes quantitatively and effectively.

Functional status and well-being of patients with chronic conditions. Results from the Medical Outcomes Study.

For eight of nine common chronic medical conditions, patients with the condition showed markedly worse physical, role, and social functioning; mental health; health perceptions; and/or bodily pain compared with patients with no chronic conditions.

The validity and relative precision of MOS short- and long-form health status scales and Dartmouth COOP charts. Results from the Medical Outcomes Study.

Variations in RP across methods and concepts were linked to differences in the coarseness of measurement scales, reliability, and content (including the effects of chart illustrations).

Functional health status levels of primary care patients.

It is concluded that functional status can be routinely recorded in medical practice to help describe severity, predict utilization, and improve the physician-patient relationship.
