A 36-item short-form (SF-36) was constructed to survey health status in the Medical Outcomes Study. The SF-36 was designed for use in clinical practice and research, health policy evaluations, and general population surveys. The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social activities because of physical or emotional problems; 3) limitations in usual role activities because of physical health problems; 4) bodily pain; 5) general mental health (psychological distress and well-being); 6) limitations in usual role activities because of emotional problems; 7) vitality (energy and fatigue); and 8) general health perceptions. The survey was constructed for self-administration by persons 14 years of age and older, and for administration by a trained interviewer in person or by telephone. The history of the development of the SF-36, the origin of specific items, and the logic underlying their selection are summarized. The content and features of the SF-36 are compared with the 20-item Medical Outcomes Study short-form.

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. Results from traditional psychometric and clinical tests of validity were compared. Principal

The final development of the Sickness Impact Profile (SIP), a behaviorally based measure of health status, is presented. A large field trial on a random sample of prepaid group practice enrollees and smaller trials on samples of patients with hyperthyroidism, rheumatoid arthritis and hip replacements were undertaken to assess reliability and validity of the SIP and provide data for category and item analyses. Test-retest reliability (r = 0.92) and internal consistency (r - 0.94) were high. Convergent and discriminant validity was evaluated using the multitrait--multimethod technique. Clinical validity was assessed by determining the relationship between clinical measures of disease and the SIP scores. The relationship between the SIP and criterion measures were moderate to high and in the direction hypothesized. A technique for describing and assessing similarities and differences among groups was developed using profile and pattern analysis. The final SIP contains 136 items in 12 categories. Overall, category, and dimension scores may be calculated.

The Sickness Impact Profile: development and final revision of a health status measure.

The Sickness Impact Profile (SIP), a measure of health status, is being developed as an outcome measure of health care. A preliminary study of the validity of the SIP was conducted on a sample of 278 subjects who were grouped into four subsamples differing in land and severity of sickness. Selfasses

The sickness impact profile: validation of a health status measure.

The development of a health status measure, the Sickness Impact Profile (SIP), is described in terms of both its conceptualization and methodology. The need for a health status measure that is sensitive and appropriate, based on sickness-related behavior, and culturally unbiased, is discussed. A model of sickness behavior is presented as a guide for methodological development. The description of the initial developmental stage of the SIP includeds detailed discussion and documentation of the collection, sorting and grouping of items that comprise the SIP, scaling of the items, scoring of the instrument, and testing and revision of the prototype instrument. Results of preliminary tests of reliability, validity, and administrative feasibility are presented. Subsequent steps in revision and finalization, now under way, are outlined.

The Sickness Impact Profile: Conceptual Formulation and Methodology for the Development of a Health Status Measure:

This report describes the results of research conducted on the reliability of the Sickness Impact Profile (SIP). The SIP is a questionnaire instrument designed to measure sickness-related behavioral dysfunction and is being developed for use as an outcome measure in the evaluation of health care. The test-retest reliability of the SIP in terms of several reliability measures was investigated using different interviewers, forms, administration procedures, and a variety of subjects who differed in terms of type and severity of dysfunction. The results provided evidence for the feasibility of collecting reliable data using the SIP under these various conditions. In addition, subject variability in relation to reliability is discussed.

The Sickness Impact Profile: reliability of a health status measure.

Numerous elements of the behavior of mother and infant monkeys caged in controlled environments were recorded during the first 15 weeks of the infants' lives. The data on these elements were analyzed for sex-related differences in mean occurrence and in developmental trends. Differences in mutual independence related to the sex of the infant began to emerge soon after birth. The male infants and mothers began life more dependent on each other, but within a few weeks showed a rapidly accelerating change to greater mutual independence. The mother played an active role in the instigation of the greater independence of a male by higher initial punishment, less retaining, less orientation to the infant and less carrying of the infant. There were no indications of sex differences in the infants' behavior to support the concept that differential development of independence is a function of the infants' instigation. However, males appeared to be responsive to their independence by becoming more interactive with the environment. They soon directed relatively less of their behavior towards their mothers.
