Estimates of the prevalence of high to very high psychological distress among Australian adults (18 years and above) derived from the Household, Income and Labour Dynamics in Australia (HILDA) Survey (red open circles with 95% confidence intervals) and from constrained models in which the fractional rates of increase in the per capita incidence of high to very high psychological distress and treatment effectiveness (δi and δr, respectively) are assumed to equal 0 (dark grey lines). Pointwise 50 and 95% credible intervals are indicated with dark grey shading and light grey shading, respectively
