Short Description of Instrument
Construct measured: Functional health and well-being.
Generic vs. disease specific: Generic.
Means of administration: Interview or Self-Administered.
Intended respondent: Patient.
# of items: 12.
# of subscales and names of sub-scales: 8 – Physical Functioning, Role – Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role – Emotional, Mental Health.
# of items per sub-scale: Varies.
Scoring: Scores are calibrated so that 50 is the average score or norm. This norm-based score allows comparison among the three surveys and across the more than 14,000 studies published in the past 20 years.
Background: Optum Incorporated's SF-12v2® Health Survey is a shorter version of the SF-36v2® Health Survey that uses just 12 questions to measure functional health and well-being from the patient's point of view.
Strengths/ Weaknesses: Particularly useful in large population health surveys or for applications that combine a generic and disease-specific health survey. Available in multiple language translations, the SF-12v2 covers the same eight health domains as the SF-36v2 with one or two questions per domain.
Psychometric Properties: The SF-12v2 is a practical, reliable, and valid measure of physical and mental health.
Administration: These surveys are for adults 18 years of age and older, and can be self-administered or interview-administered. Multiple other modes of administration are offered, such as online, PDA, and more. Translations are available for multiple languages and countries.
Administration takes only 2–3 minutes.
Sport-Related Concussion-Specific:
Advantages: 12 item measure of overall functional health and well-being that includes the following subscales- physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Brief (2–3 min) and reliable measure. Scores are normalized with range to 100 with mean of 50. Translated in several languages. There are online, paper and pencil versions. It can be used with 1 and 4 week recall intervals.
Limitations: Lack of overall score. No clinical cut-offs and only normative comparison data.
Subpopulation: Adults only 18+
