DESIGN: Cross-sectional survey.
SETTING: Community setting (22 countries representing all 6 World Health Organization regions).
PARTICIPANTS: Persons (N=12,108) with traumatic or nontraumatic SCI aged at least 18 years, living in the community and able to respond to one of the available language versions of the questionnaire.
INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: LS measured by 5 items selected from the World Health Organization Quality of Life Assessment-BREF: satisfaction with overall quality of life, health, daily activities, relationships, and living conditions. LS index was calculated as the mean of these 5 items.
RESULTS: The highest level of LS was reported by persons with SCI living in the United States, Malaysia, and Switzerland (mean range, 3.76-3.80), and the lowest was reported by persons with SCI living in South Korea, Japan, and Morocco (mean range, 2.81-3.16). There was a significant cubic association between LS index and GDP-PPP. Regression tree analysis revealed the main variables differentiating LS index were GDP-PPP and monthly income, followed by time since injury and education.
CONCLUSIONS: Life satisfaction reported by persons with SCI related mainly to their country economic situation expressed by GDP-PPP and monthly income. The results of this study underscore the need for policy dialogues to avoid inequalities and improve the life experience in persons with SCI.
