This study aimed to assess patients' levels of belief, benefits and barriers toward physical activity, and to identify factors associated with physical activity performance in patients with type II diabetes mellitus (T2DM). The study was carried out using cross-sectional correlation design. Subjects from the endocrinology and metabolism outpatient departments of a teaching hospital in northern Taiwan were recruited by consecutive sampling. A total of 149 patients with type II DM were recruited. More physical activity was associated with stronger physical activity beliefs, including recovery self-efficacy, action and coping planning, and maintenance self-efficacy, which explained 40.9% of variance in physical activity performance. Patient-centered physical activity programs (resistance exercise, daily walking, or Tai Chi exercise) can reduce patients' barriers toward performing physical activity.
