A Modified Exercise-induced Feeling Inventory for Chronic Training and Baseline Profiles of Participants in the...

An earlier study reported on the development of a scale to measure feeling states during acute bouts of exercise: the Exercise-induced Feeling Inventory (EFI-A). The present study reports on the psychometric properties of a revised scale to assess responses to habitual or chronic physical activity: the EFI-C. The EFI-C was administered during baseline testing to 830 sedentary men and women patients with a mean age of 51.5 years. Factor analytic procedures revealed that the EFI-C consisted of two factors, one assessing pleasant feeling states and a second that taps the unpleasant experience of physical exhaustion. Both subscales have excellent internal consistency reliability coefficients (0.90) and are reasonably stable over time, having test-retest coefficients in excess of 0.70. The scales correlated in expected directions with related constructs and in preliminary analyses showed an anticipated pattern of sensitivity to physical activity interventions. Mean scores for various demographic groups are reported. Future research should examine whether the EFI-C is a predictor of adherence to physical activity and its potential role in mediating the positive mental health effects of physical activity.
