THE PSYCHOMETRIC PROPERTIES OF SELF-TALK QUESTIONNAIRE-VIETNAMESE VERSION

Abstract

The aim of this study was to validate the psychometric properties of Self-talk questionnaire-Vietnamese version, which originally developed by Zervas et al., 2007 (21). For the construct validity, data from 121 collegiate athletes, who studied in Hochiminh City University of Sport, was examined by using factor analysis (exploratory and confirmatory). Like the original Self-talk questionnaire, the results from EFA also pointed out two-factor solution as motivational and cognitive (21). The CFA’s results demonstrated that all indices [χ2 = 46.78, df = 39, χ2 / df = 1.20, RMSEA = .04; SRMR = .06; NNFI = .97; CFI = .98] met the goodness-of-fit standard. The results of Cronbach’s alpha coefficient and intra-class correlation coefficient were fully acceptable for a new instrument. In conclusion, the S-TQ Vietnamese version can be used to identify the cognitive and motivational functions of self-talk in Vietnamese athletes.
