CONFIRMATION OF THE BASIC PSYCHOLOGICAL NEEDS IN EXERCISE SCALE (BPNES) WITH A SAMPLE OF PEOPLE WHO DO HEALTHY EXERCISE

This study aimed to cross-validate the psychometric properties of the Basic Psychological Needs in Exercise Scale (BPNES) by Vlachopoulos and Michailidou, 2006 in a Spanish context. Two studies were conducted. Confirmatory factor analysis results confirmed the hypothesized three-factor solution In addition, we documented evidence of reliability, analysed as internal consistency and temporal stability. Future studies should analyse the scale's validity and reliability with different populations and check their experimental effect
