Validation of the Malay version of the recovery-stress questionnaire for athletes: Application of confirmatory factor analysis and exploratory structural equation modeling

The Recovery-Stress Questionnaire for Athletes (RESTQ-Sport-52) is a tool developed to measure the frequency of stress associated through recovery activities with strong theoretical foundations. The study aims to examine the psychometric properties of the Malay version of RESTQ-Sport-52 using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM). A cross-sectional study with purposive sampling method was employed. There were 617 undergraduate university students in Malaysia participated in the study with mean age of 20 years old (SD = 1.5). The majority of the participants were female (66.1 %), Malay (76 %) and participated in at least one sport or exercise. The RESTQ-Sport-52-M consisted of 52 items with two main sections; (1) general stress and recovery scales and (2) sport-specific stress and recovery scales. Mplus 8.3 was used to perform the CFA and ESEM analysis to examine the construct validity and reliability of RESTQ-Sport-52-M. For measurement model assessment using CFA, the final model of general-stress/recovery and sport-specific stress/recovery indicated a fit based on several fit indices. However, in the measurement model assessment using ESEM, the fit indices for model of general-stress/recovery (CFI = 0.935, SRMR = 0.037, RMSEA = 0.045) and sport-stress/recovery (CFI = 0.923, SRMR = 0.036, RMSEA = 0.044) were generally improved. The construct reliability for measurement models of RESTQ-Sport-52-M ranged from 0.76 to 0.89. The ESEM approach yielded a better fit indices compared to the CFA approach for both scales. The RESTQ-Sport-52-M (50 items) were considered a more valid and reliable questionnaire to measure recovery and stress in sports for Malaysian sample.
