| Abstract: | The purpose of this study was to provide three construct validity evidence for using fitness center attendance electronic records to objectively assess the frequency of leisure-time physical activity among adults. One hundred members of a fitness center (45 women and 55 men; aged 18 to 64 years) completed a self-report leisure-time physical activity questionnaire. The theory of planned behavior constructs (e.g., intention and perceived behavioral control), VO2max, and % BF were assessed. Fitness center attendance electronic records were expressed as the weekly mean number of mandatory check-in records retrieved from the fitness center's electronic database over a 12-week period prior to participant's physical fitness evaluation. A continuous (frequency) and categorical (“adherent” versus “non-adherent”) scores were computed. Results indicated that perceived behavioral control was associated with fitness center attendance electronic records and mediated the fitness center attendance electronic records–intention relationship. Fitness center attendance electronic records were associated with VO2max and self-report leisure-time physical activity. Therefore, results provide three evidence of construct validity of using fitness center attendance electronic records scores to assess leisure-time physical activity behavior. |
