VALIDITY AND RELIABILITY OF THE EXERCISE MAINTENANCE MOTIVATION SCALE AMONG FITNESS CENTER MEMBERS
Main Article Content
Abstract
Background: Exercise motivation plays a crucial role in maintaining health-promoting physical activity habits.Objectives: To assess the structural validity and reliability of the exercise maintenance motivation among fitness center members. Materials and methods: A cross-sectionalstudy was conducted on 375 participants who are fitness center members in Can Tho city, Vietnam. The 30-item exercise motivation scale was used through self-administrative questionnaire based on self-determination theory (SDT). Construct validity and reliability of the scale were assessed using CFA based on factor loadings (≥0.5), average variance extracted (AVE > 0.5), composite reliability (CR > 0.7), and model fit indices (χ²/df, RMSEA, SRMR, CFI, and IFI) according to acceptable thresholds. Results: Findings showed that males accounted for a slightly higher proportion (51.2%) compared to females (48.8%). The mean age of participants was 29.24 years (SD = 10.28). A total of 26/30 motivation statements were retained after Cronbach's alpha was 0.83. Five components of the exercise maintenance motivation scale were identified, including: Exercise achievement (10 items); Controlled motivation (4 items), Exercise environment (5 items); Exercise integration with life goals (3 items); and Exercise enjoyment (4 items). Conclusions: The validity and reliability of the exercise maintenance motivation scale were acceptable and consistent with SDT.
