  • BDI (prop. score), depression score on the beck depression inventory; PSS, perceived stress scale. Proportion scores are scores divided by total possible score. AIC, Akaike information criterion; BIC, Bayesian information criterion; ICC, intraclass correlation; RMSE, root mean squared error.

  • +p < 0.1, *p < 0.05, **p < 0.01, ***p < 0.001.
