  1. As none of the 95% confidence intervals for the estimate of indirect effects included zero, there is a statistically significant indirect effect of action planning and coping planning on all six clinical behaviours through habit
  2. AP action planning, CP coping planning
  3. **p < 0.01; ***p < 0.001
  4. SE = standard error
