Table 6 shows mixed-model estimates of the Global Assessment of Functioning (GAF) in models with treatment included as a predictor (SDC: the step-down condition, OPC: the outpatient condition). (A): Mean estimated GAF (SE: standard error) at baseline (intercept) and change per month (linear slope) during the trial presented as (1) ∆ (SDC-OPC): Difference (∆) between SDC and OPC, and (2) Moderator effects: (SDC-OPC) difference for subgroups of patients with (a) avoidant PD, APD: ∆ (SDCAPD - OPCAPD) and (b) borderline PD, BPD: ∆ (SDCBPD - OPCBPD). Akaikes Information Criterion (AIC) indicates goodness of fit for each model. (B): 36-month GAF change: Estimations of 36-month GAF change and incremental effects (when a significant difference existed between SDC and OPC) based on mixed-model predicted values. P-values are presented if p < 0.05, ns indicates p > 0.05.
