Capturing Exercise Psychological Need Satisfaction Among Older Adults: The BPNES

Regular exercise participation which is a component of promoting health and healthy aging among older adults necessitates the creation of environments that fulfill participants' needs for autonomy, competence, and relatedness, thus, providing opportunities to promote authentic interest in the activities and meaningful social engagement. Appropriate tools to capture satisfaction of these needs may prove invaluable to gain an understanding of the effectiveness of exercise programs from participants' perspective. The aim of the study was to examine psychometric aspects of the Basic Psychological Needs in Exercise Scale (BPNES) scores based on responses of 675 older adult Greek exercise participants, men and women, aged 65 to 80 years, attending indoor group-based exercise programs. The data supported the factorial validity, internal reliability, nomological validity, and equivalent item interpretation of BPNES scores between groups differing in demographic characteristics. Older adults with exercise experience greater than three years reported higher exercise needs satisfaction for all three needs compared to those exercising less than three years. The favorable psychometric characteristics of the BPNES in this population make it a valuable tool for the assessment of the extent to which older adults' needs for autonomy, competence, and relatedness are fulfilled in group-based exercise settings.
