Quality of Life Concepts

Secondary Health Conditions

The Short Form Health Survey (SF-12)

Description: A measure of perceived health (health-related quality of life [QoL]) that describes the degree of general physical health status and mental health distress [1].

Format: 12 items, derived from the physical and mental domains of the Short Form Health Survey-36 (SF-36).

Scoring: Norm-based. Separate summary scores are obtained for each of the physical and mental domains by summing across all 12 items for each. Higher scores indicate higher levels of health. Published data and norms for most health conditions in the general population have been reported for Canada and the USA.

Administration and Burden: Interviewer-administered; Self-administered. Approximately 3 minutes.

Psychometrics for SCI: In a study of veterans with SCI, the SF-12 was reported to have good discriminant function, convergent validity, and correlated strongly with the SF-36 [2].  However, a more thorough testing of its psychometric strengths is needed [2].

Languages: The SF-12 has been translated for use in over 40 languages.

QoL Concept: The SF-12 is a measure Health-Related QoL, which corresponds to Boxes B (societal standards and priorities) and C (achievements; health-related QoL) of Dijker’s Model.
