1 Kessler 10 coefficient estimated at mean after back-transformation and controlling for confounders.
2 Linear mixed model regresses psychological distress on survey year.
3 The probability value compares population means of psychological distress scores over time and is derived from the linear mixed models.
4 Beta values represent the results from linear mixed models including reported exposures to WHP initiatives but with no interaction term (i.e. additive models).
