Abstract
The aim of the study was to modify the Amotivation Toward Exercise Scale-2 by dropping the outcome amotivation beliefs subscale while retaining the capacity, effort, value, and task characteristics amotivation beliefs. Data from 515 Greek nonexerciser adults aged 19-64 years and 399 Greek nonexerciser older adults aged 65-82 years, men and women, supported the latent four-factor structure of the Revised Amotivation Toward Exercise Scale-2 scores within each sample separately. The hierarchical model was also supported. Measurement invariance of Revised Amotivation Toward Exercise Scale-2 scores was supported across groups of gender, age, body mass index, and educational levels within adults and older adults. Configural measurement invariance supported a replicable factor structure across adults and older adults. Metric and strong invariance was supported across middle-aged and older adults but not between younger and older adults. Full measurement invariance was supported between younger and middle-aged adults.
期刊介绍：
The Journal of Sport & Exercise Psychology (JSEP) is a peer-reviewed publication designed to stimulate and communicate research theory in all areas of sport and exercise psychology. JSEP emphasizes original research reports that advance our understanding of human behavior as it relates to sport and exercise. Comprehensive reviews employing both qualitative and quantitative methods are also encouraged, as well as brief reports of soundly designed research studies that are of special interest or importance. Areas of interest include research in social, clinical, developmental, and experimental psychology, as well as psychobiology and personality. Moreover, the terms sport and exercise may pertain to either the independent or dependent variables. Generally speaking, work on motor control processes, studies of sport as a social institution, or broader social issues are beyond the scope of JSEP. A wide variety of methods are acceptable for studying sport and exercise psychology topics.
