Table 4. Posterior predictive p-values for the pairwise item correlations of the GAD-7.
| Variable | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Feeling nervous anxiety | ||||||
| Not able to stop worrying | .088 | |||||
| Worrying too much | .872 | .000 | ||||
| Trouble relaxing | .504 | .552 | .954 | |||
| Hard to sit still | .362 | .244 | .126 | .000 | ||

Note. An entry is computed as 2min(F(tobs),1-F-(tobs)), wherein F(tobs) refers to the empirical distribution function (evaluated at the observed item correlation tobs) of the pairwise item correlations generated from simulated data sets adhering to the graded response model with item parameters drawn from the posterior distribution [26,27].
