Modeling longitudinal change in depressive and anxious symptom severity over time. A Coefficients for the fixed effects in the LME model accounting for the change in PHQ-9 over time. Both baseline PHQ-9 and GAD-7 predict higher depressive symptom severity, as does a depressive disorder diagnosis. In contrast, incident session number predicts lower symptom severity. B Coefficients for the fixed effects in the LME model accounting for the change in GAD-7 over time. Baseline GAD-7 and a depressive disorder diagnosis predict worse anxious symptom severity while incident session predict lower anxious symptom severity
