A total of 441 patients were randomized to receive 12 months of health coaching (n=224) vs. usual care (n=217). At baseline, the two groups were similar to those in the usual care group with respect to demographic characteristics and levels of trust in their provider. After 12 months, the mean trust level had increased more in patients receiving health coaching (3.9 vs. 1.5, p=0.47), this difference remained significant after adjustment for number of visits to primary care providers (adjusted p=.03).
