The psychometric properties of the Vietnamese Version of the Five Facet Mindfulness Questionnaire

Background: Although recent decades have witnessed a growing interest in mindfulness with the development of many mindfulness scales and their adaptation to different cultures, there has been no attempt at developing or adapting a mindfulness scale for Vietnamese people. To fill this gap and encourage the study of mindfulness in Vietnam, we adapted a 20-item short-form of the Five Facet Mindfulness Questionnaire (FFMQ-20) into Vietnamese, which we called the FFMQ-V, and examined its psychometric properties in a series of three independent studies. Methods: In Study 1, using a college sample (N = 412) we conducted several exploratory factor analyses to elucidate the factor structure of the FFMQ-V. In Study 2, using an independent college sample (N = 344) we performed a confirmatory factor analysis (CFA) to test the goodness-of-fit for all obtained factor models from Study 1. In this study, we also examined the discriminant validities of the FFMQ-V by correlating mindfulness and other related psychological constructs, including acceptance, nonattachment, depression, anxiety, and stress. In Study 3, we replicated all data analyses in Study 2 using a community sample of young adults (N = 574). Results: Across all Studies, our results indicated that the hierarchical five-factor model with method factors best captured the latent structure of the FFMQ-V. Our results also showed that the mindfulness facets met our expectations as they correlated positively with the acceptance and nonattachment and negatively with the depression, anxiety, and stress. Conclusions: In aggregate, our EFA and CFA results provided strong evidence for the hierarchical five-factor model with method factors in both community and college samples, suggesting that the FFMQ-V can be used to measure trait mindfulness of the Vietnamese young adults.
