Background: Stroke is a major, chronically disabling neurological disease, which often radically and permanently changes the lives of the patients. The assessment between of Turkish version of quality of life Index –stroke version III in stroke patients has not been validated in Turkey.
Methods: The study consisted of 216 patients with stroke to evaluate acceptability, reliability and validity of the Turkish version Quality of Life Index in stroke patients. The survey included demographic questionnaire and disease information, The Quality of Life –Stroke Version III Index, Barthell Index.
Results: Internal consistency Cronbach alpha for the QLI-Stroke version items was 0.96. There was no significant difference between pre-test and post-test ratings for all
four subscale scores and the global score (p>0.05). Test –retest reliability measured was r: 0.72 (p< 0.05). Concurrent validity was examined by correlating QLI-stroke version Index and Barthell Index. The results of correlation coefficient are low to show validity of the scale even though these were statistically significant.
Conclusion: The Turkish version of Quality of Life Index in stroke patients was found to be acceptable, reliable and valid tool for use among stroke patients. It is easy and practical to use for both informants and investigators and acceptable for research and clinical practice.
