Reflective functioning and its potential to moderate the efficacy of manualized psychodynamic therapies versus other treatments for borderline personality disorder.

Journal of Consulting and Clinical Psychology, Vol 91(1), Jan 2023, 50-56; doi:10.1037/ccp0000760Background: Impaired reflective functioning (RF) is common among patients with borderline personality disorder (BPD). Transference-focused psychotherapy (TFP) has been demonstrated to improve RF compared to other common BPD treatments. If RF reflects a treatment mechanism for TFP, differences in pretreatment RF may also serve as a prescriptive factor for TFP’s effects. Method: A total of 194 patients with BPD were randomized across two clinical trials to receive TFP (n = 83), dialectical behavior therapy (DBT; n = 31), supportive psychodynamic therapy (SPT; n = 28), or an enhanced treatment as usual (eTAU; n = 52). A mixed-effects model was used to examine whether baseline RF interacted with treatment condition to predict slopes of change in the Brief Symptom Inventory, the shared symptom outcome between trials. Moderation of changes in RF was also examined. Results: Treatment interacted with baseline RF to predict BSI slopes (p = .011). In TFP/SPT, RF did not predict outcomes, β = −0.00, p = .973, while higher RF was associated with relatively better outcomes in DBT/eTAU, β = −0.54, p
