Table 5.

Results of Final Multi-Level Models Predicting Post-Treatment Anxiety Sensitivity Index Scores from session 3 Working Alliance Inventory Scores (n = 133) after using Backwards Stepwise Elimination. Blank spaces mean that the measure was not included in the final model. Predictors that are not presented here never met criteria for inclusion in the final model (p < 0.15).
