The self-efficacy enhancing intervention produced results that are consistent with other behavioral interventions designed to increase PA. People with COPD increased PA by 1,263 steps/day after 12 weeks of an Internet-based walking program, 785 steps/day after 12 weeks of a customized exercise counseling program,36 and 609 steps/day after 36 weeks of cell phone supported self-monitoring intervention. In addition, our results were consistent with interventions that combined exercise and behavioral strategies. Effing et al. demonstrated an increase of 876 steps/day after a 52-week self-management plus COPE active intervention that included self-management and exercise. Pomidori et al. demonstrated an increase in time spent walking at an intensity greater than 3 METs after 18 weeks of speed walking with a metronome to pace the walking and twice a month telephone calls.
