Short Form (36) Health Survey (SF-36)
The Short Form (36) Health Survey (SF-36) evaluates the functional health and well-being of patients.
The test consists of 36 questions and requires 10 minutes to administer. The Sf-36 includes a multi-item scale with 8 subscales. A physical summary and a mental summary are included in the test scoring. SF-12 is the reduced version of the survey and requires only 2 minutes is necessary for completion.
Reliability and Validity
According to numerous studies (i.e., Vikrey et al., 1995), the evidence for the validity of the SF-36 is considerable. A Cronbach alpha rating ranging from .67 to .94 was calculated for the eight subscales. Excluding the social functioning subscale, all of the subscales received a reliability coefficient above 0.75. The SF-36 was best correlated with the Expanded Disability Status Scale (EDSS) and the Ambulation Index as a physical functioning scale.
