Best-fit	11 items, ‘once’ + quadratic			11 items, ‘more than once’			11 items, ‘once’ (by AIC)
Cumulative Risk –Continuous	.176	48,645	.732	.199	27,979	.796	.041	67,037	.608
Best-fit	9 items, ‘once’ + quadratic			11 items, ‘more than once’			11 items, ‘once’ (by AIC)

R² is Nagelkerke. (by AIC) indicates that the model comparisons within that model category were not significantly different from each other, and the best fit model was chosen as that with the smaller AIC. For the depression outcome only, the CR continuous model included a quadratic term
