| Chronology of Development |

The changes in the SF-12v2® Health Survey relative to the original SF-12® Health Survey, which are a product of more than 10 years of experience with findings reported in thousands of publications about the SF-36® Health Survey and the SF-12® Health Survey, follow exactly those previously recommended and adopted for the SF-36v2® Health Survey (see Ware, Kosinski and Dewey, 2000)
Relative to the original SF-12® Health Survey, improvements in the SF-12v2® survey include:
•Improvements in instructions and questionnaire items to shorten and simplify the wording and make it more familiar and less ambiguous;
•An improved layout for questions and answers in the self-administered forms that makes it easier to read and complete, and that reduces missing responses;
•Greater comparability with translations and cultural adaptations widely-used in the U.S. and in other countries;
•Five-level response choices in place of dichotomous response choices for four items in the two role functioning scales; and
•Five-level (in place of six-level) response categories to simplify items in the Mental Health (MH) and Vitality (VT) scales.

| Additional Format Information |
|
The PCS (Physical Component Summary)and MCS (Mental Component Summary) scores provide, as their labels suggest, a summary of the respondent's health status from both broad physical health perspective and a broad mental health perspective. Results on the PCS and MCS measures should serve as a starting place for determining whether functional limitations exist in either of the two major components of health; if so, the health domains contributing greatest to the affected dimension(s) and the items they comprise require further examination to ascertain their potential contribution to the respondent's impaired functioning.
