Construct Validity of Chinese Version of Kinesthetic and Visual Imagery Questionnaire / 中国康复理论与实践

ABSTRACT

Objective To explore the construct validity of the Chinese version of Kinesthetic and Visual Imagery Questionnaire (KVIQ)-20 and KVIQ-10 in stroke patients and normal people. Methods From October, 2012, to March, 2014, 60 stroke patients and 60 nor-mal people with matched gender and age participated in this study. They were assessed with the Chinese version of KVIQ-20 and KVIQ-10. The construct validity was investigated with factor analysis. Results Two factors were extracted from KVIQ-20 for stroke patients after vari-max rotation, that accounted for 62.4%of the variance, as well as KVIQ-10 with 67.6%of the variance. Two factors were extracted from KVIQ-20 for normal people with 76.1%of the variance, as well as the KVIQ-10 with 69.6%of the variance. The factors could be named as visual imagery and kinesthetic imagery. Conclusion The Chinese version of KVIQ-20 and KVIQ-10 has good construct validity for assess-ing motor imagery from the dimensions of visual imagery and kinesthetic imagery, both in patients with stroke and normal people.
