Reliability and Validity of A Chinese Version of the Stroke Action Test: A New Instrument For Assessment of Stroke Knowledge and Response

Background: the public’s cognition of stroke and responses to stroke symptoms are important to prevent complica-tions and decrease the mortality when stroke occurs. the aim of study was to develop and validate the chinese version of the stroke action test (c-stat) in a chinese population. methods: this study was rigorously implemented with the published guideline for the translation, adaptation and va-lidation of instruments for the cross-cultural use in healthcare care research. a cross-sectional study was performed among 328 stroke patients and family members in the department of neurology in the second hospital of lanzhou university, gansu province, china in 2014. results: the chinese version of the instrument showed favorable content equivalence with the source version. values of cronbach’s alpha and test-retest reliability of the c-stat were 0.88 and 0.86, respectively. principal component analysis supported four-factor solutions of the c-stat. criterion-related validity showed that the c-stat was a sig-nificant predictor of the 7-item stroke symptom scores (r = 0.77; t = 21.74, p< 0.001). conclusion: the c-stat is an intelligible and brief psychometrical tool to assess individuals’ knowledge of the ap-propriate responses to stroke symptoms in chinese populations. it could also be used by health care providers to as-sess educational programs on stroke prevention.
