Key MethodRegression methods were used to select and score 12 items from the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) to reproduce the Physical Component Summary and Mental Component Summary scales in the general US population (n=2,333). The resulting 12-item short-form (SF-12) achieved multiple R squares of 0.911 and 0.918 in predictions of the SF-36 Physical Component Summary and SF-36 Mental Component Summary scores, respectively. Scoring algorithms from the general population…

Replicability of SF-36 summary scores by the SF-12 in stroke patients.

The SF-12 can be used at the summary score level as a substitute for the SF-36 in stroke survivors capable of self-report under conditions where the mental health summary scores of proxy assessments are influenced by patient age, thereby limiting the replicability of theSF-36.

Psychometric Properties of the Brazilian 12-Item Short-Form Health Survey Version 2 (SF-12v2)

Initial evidence was showed in favor of using the SF-12v2 as a measure of physical and mental health in the Brazilian context and convergence validity was tested with measures of health-related self-care, subjective happiness, life satisfaction, depression and self-efficacy.

Construct validity of the SF-12 in three different samples.

These observations challenge the validity and interpretability of SF-12 scores among the elderly, people with PD and stroke survivors, and the standard orthogonally weighted SF- 12 scoring algorithm is cautioned against.

Is the SF-12 version 2 Health Survey a valid and equivalent substitute for the SF-36 version 2 Health Survey for the Chinese?

The SF-12v2 was valid, reliable and sensitive for the Chinese and is an equivalent substitute for the SF-36v2 for the summary scales.

Validity of SF-12 summary scores in a Greek general population

Evidence on the validity of the Greek version of the 12-item Health Survey is provided and its use in Greek health status studies as a brief, yet valid, alternative to the SF-36 is supported.

Using the 12-item Short Form health survey (SF-12) to measure quality of life among older people

The instrument generally showed acceptable validity and reliability, except for its factor structure, and new determinants for non-respondents of SF-12 were found, such as type of living conditions, being worried about health, and social network.

Correlated physical and mental health summary scores for the SF-36 and SF-12 Health Survey, V.1

Correlated physical and mental health summary scores for the SF-36 and SF-12 derived from an obliquely rotated factor solution should be used along with the uncorrelated summary scores.

The measurement properties of the MCS-12 in stroke appear reasonable unless milder mental health problems are of interest, whereas those of the PCS-12 are less acceptable.

Beware of the origin of numbers: Standard scoring of the SF‐12 and SF‐36 summary measures distorts measurement and score interpretations

It is recommended that the standard SF-12 scoring algorithm be abandoned in favor of alternatives that provide more valid representations of physical and mental health, of which raw sum scores appear the simplest.

Assessment of the validity and reliability of the Indonesian version of Short Form 12 (SF-12)

This study provides the first evidence that SF-12 is a reliable and valid measure of HrQoL in Indonesian middle-aged and older adults.
