OBJECTIVE: To assess and compare the validity of 3 life satisfaction instruments
in persons with spinal cord injury (SCI). DESIGN: Cross-sectional study 5 years
after discharge from inpatient rehabilitation. SETTING: Eight rehabilitation
centers with specialized SCI units. PARTICIPANTS: Persons (N=225) with recently
acquired SCI between 18 and 65 years of age were included in a cohort study. Data
were available for 145 persons 5 years after discharge. INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURES: The Life Satisfaction questions (LS
Questions), the Life Satisfaction Questionnaire (LiSat-9), and the Satisfaction
With Life Scale (SWLS). RESULTS: There were no floor or ceiling effects. Cronbach
alpha was questionable for the LS Questions (.60), satisfactory for the LiSat-9
(.75), and good for the SWLS (.83). Concurrent validity was shown by strong and
significant Spearman correlations (.59-.60) between all 3 life satisfaction
instruments. Correlations with measures of mental health and participation were
.52 to .56 for the LS Questions, .45 to .52 for the LiSat-9, and .41 to .48 for
the SWLS. Divergent validity was shown by weak and in part nonsignificant
correlations between the 3 life satisfaction measures and measures of functional
independence and lesion characteristics. CONCLUSIONS: Overall, the validity of
all 3 life satisfaction measures was supported. Despite questionable internal
consistency, the concurrent and divergent validity of the LS Questions was at
least as good as the validity of the LiSat-9 and the SWLS.
