The Short Form 12 Health Survey is a validated 12-item-tool for generic evaluation of patient quality of life. Over eight different domains, it evalues general physical and mental health status. It is the shorter version of the SF-36 questionnaire.<\/a><\/p>

The questionnaire items in the SF-12 span several domains, including physical functioning, physical role, general health, energy\/fatigue and mental health. The results are tabulated as two scores – one physical component and one mental component. As a non-disease-specific tool, the SF-12 is suitable for general populations and has thus found application in disciplines like orthopedics, cardiology and neurology.\u00a0<\/p>

Generic evaluation of patients physical and mental health status is the primary goal and indication of the SF-12.1<\/a>, 2<\/a><\/sup> Due to its generalizibility, the tool has already found application in several medical subdisciplines.<\/p>

In the context of orthopedics, studies evaluating the effects of osteoarthritis and musculoskeletal disease, and cervical spine surgery on overall patient quality of life have used the SF-12.3<\/a>, 4<\/a><\/sup><\/p>

In other medical subdisciplines, the questionnaire has been administered to patients with myocardial infarction (cardiology) and neurological patient groups with stroke.5<\/a>, 6<\/a><\/sup><\/sub><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Items - Dimensions - Completion time<\/h4>\t\t\t\t<\/div>\n\t\t\t\t

The SF-12 includes 12 items with multiple-choice questions. The number of possible response options varies from 2 to 6. Only one answer can be selected.<\/p>

The questionnaire covers various dimensions. The scope includes the domains of physical functioning (2 questions), physical limitations in daily activities (2 questions), bodily pain (1 question), general health (1 question), energy\/fatigue (1 question), social functioning (1 question), emotional limitations in daily activities (2 questions) and mental health (2 questions).<\/p>

It takes less than 2 minutes to complete the SF-12 for the majority of individuals.7<\/sup><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Scoring method<\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The results of the SF-12 health survey are represented by one physical component score (PCS)<\/strong> and one mental component score (MCS),<\/strong> with the PCS including the items inquiring parameters of physical functioning and pain, while the MCS focuses on psychological and mental health questions.7<\/sup><\/a><\/p>

A norm-based scoring leads to scores where 50 represents the average in comparison with the American reference population. The standard deviation is 10 (a score of 60 means one standard deviation above the US average). Every answer is linked with an indicator variable and different regression weights during the score calculation. The patients answers can be send to qualitymetric.com, where an API scores the raw data.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Score interpretation<\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Higher values are linked with a better health status, while lower values depict a worse health status.<\/strong><\/p>

The score is based on normally distributed statistical values with 50 as the mean value and 10 as the standard deviation. Additionally, an individual interpretation of every single question is possible.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The SF-12 is generalizable enough to be applicable in diverse patient populations.\u00a0 Moreover, the PCS and MCS scores were shown to be identical in an comparison study with the longer SF-36 survey.12<\/sup><\/a><\/p>

Due to its brevity, it can be conducted quickly and is therefore easy to implement in routine clinical practice. The end score is statistically intuitive to interpret.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The scoring system is complicated and takes a longer time in comparison to other questionnaires.<\/p>

Additionally, high rates of missing data have been observed. This represents a a severe complication because interpretation with missing answers is impossible.13<\/sup><\/a><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t
