Description: A measure of subjective well-being that assesses satisfaction with various domains of life by taking into account their relative importance to the respondent [1]. 

Format: 74 items divided into two parts: Part 1 (Satisfaction; 37 items) and Part 2 (Importance; 37 items). Each item for both parts is ranked on a six point scale:

1 = Very Dissatisfied

3 = Slightly Dissatisfied
4 = Slightly Satisfied
5 = Moderately Satisfied
6 = Very Satisfied

Scoring: The scoring scheme (see details below on where to obtain) provides a score range from 0 to 30, with higher scores reflecting higher levels of QoL. A score for total QoL or each of the sub-scales may be calculated: Health and Functioning; Socioeconomic Status; Psychological and Spiritual Well-Being; Family Relationships.

Administration and Burden: Caregiver-administered; Interviewer-administered; Proxy-administered; Self-administered.  Approximately 10 minutes.

Psychometrics for SCI: Support for the homogeneity reliability with Cronbach’s alpha scores of .73 to .99 [2]. Further work required to establish psychometric properties for the spinal cord injury (SCI) population, especially with respect to test re-test reliability.

Language(s):  The SCI version is available in English, French and Lithuanian.
