Satisfaction with Life Scale
Availability
The instrument is freely available here: Satisfaction with Life Scale Instrument
Classification
Basic: Moderate/Severe Rehabilitation and Concussion/Mild (TBI)
 
Supplemental: Spinal Cord Injury (SCI), Sport-Related Concussion (SRC) Acute (time of injury until 72 hours) and  Acute Hospitalized and Epidemiology (TBI)
Short Description of Instrument
The Satisfaction With Life Scale (SWLS) measures the respondents overall satisfaction with life. The SWLS consists of 5 questions answered on a 7-point Likert scale ranging from 1=strongly disagree to 7=strongly agree. Administration time is brief and is rarely more than 2–3 minutes.
Scoring
Total score ranges from 7–35. Higher scores indicate better satisfaction with life.
Rationale/Justification
SCI: The measure has been widely used with SCI samples across the US including SCIMS centers. In general, the outcome measure has good psychometric properties and reasonably good clinical utility. It is easy to administer and score. Life satisfaction after SCI can be reliably measured by means of the SWLS. Correlates of subjective well-being parallel those suggested by earlier studies and those for the population at large. The effects of life satisfaction on social participation, health, and other aspects of life need further study (Dijkers, 1999).
 
Sport-Related Concussion-Specific:
 
Advantages: Specific to sport concussion--includes acute timeframe (time of injury until 72 hours). Short measure consists of 5 questions answered on a 7 point Likert scale which takes <4 minutes to administer. It is widely used across the US. The measure has good psychometric properties and reasonably good clinical utility. It is easy to administer and score.
 
Limitations: Age range of scale not mentioned but may not be relevant for pediatric patients either.
