The unstandardized regression coefficients (B)a for the habit index, using time-ordered habit index and current adherence as the covariates with subsequent adherence as the dependent variable in a multiple regression
| Habit index unstandardized coefficient, mean (95% CI) | |
|---|---|
| Overall (n=123) | 0.30 (−1.04 to 1.65) |
| Adherence consistently low, ie, ≤25% (n=6) | 3.03 (−9.68 to 15.76) |
| Variable adherence (n=99) | 0.08 (−1.44 to 1.60) |
| Adherence consistently high, ie, >75% (n=18) | 0.61 (−1.90 to 3.13) |
Note:
a
A regression coefficient of 0.30 meant that 1 unit increase in the habit index (which can vary from 1 [ie, weakest habit] to 7 [ie, strongest habit]) was associated with a 0.3% increase in the subsequent week’s adherence (which can vary from 0 to >100%).
