However comparability of measurement results between countries depends on the cross-cultural validity of the applied instruments. The study examined the metric quality and cross-cultural validity of the Satisfaction with Life Scale SWLS the Life Satisfaction Questionnaire LISAT-9 the Personal Well-Being Index PWI and the 5-item World Health Organization Quality of Life Assessment WHOQoL-5 across six countries in a sample of persons with spinal cord injury SCI . Methods A cross-sectional multi-centre study was conducted and the data of 243 out-patients with SCI from study centers in Australia Brazil Canada Israel South Africa and the United States were analyzed using Raschbased methods. Results The analyses showed high reliability for all 4 instruments person reliability index . . Unidimensionality of measurement was supported for the WHOQoL-5 Chi2 df 10 p .088 partially supported for the PWI Chi2 df 16 p .480 but rejected for the LISAT-9 Chi2 df 18 p .000 and the SWLS Chi2 df 10 p .000 based on overall and item-wise Chi2 tests principal components analyses and independent t-tests. The response scales showed the expected ordering for the WHOQoL-5 and the PWI but not for the other two instruments. Using differential item functioning DIF analyses potential cross-country bias was found in two items of the SWLS and the WHOQoL-5 three items of the LISAT-9 and four items of the PWI. However applying Rasch-based statistical methods especially subtest analyses it was possible to identify optimal strategies to .
