Adding nuance to the between-therapist effect on patient outcomes, research has increasingly demonstrated that a given therapist can differ in their effectiveness depending on who they treat (e.g., patients with different racial/ethnic identities) and/or what they treat (e.g., patients with different presenting problems). This preregistered study examined whether individual therapists are also more or less effective depending on how they treat their patients; that is, delivering one type of therapy versus another. We did so in the context of an individual participant data meta-analysis of clinical trials that compared classes of cognitive-behavioral therapy and psychodynamic therapy for depression. The meta-analytic sample included 30 therapists who were crossed with treatment condition and 492 patients (M = 25.08 patients per therapist; SD = 15.77). Patients completed measures of depression at baseline and posttreatment. Multilevel structural equation models revealed significant variability in the within-therapist treatment condition-outcome association (p < .001), indicating that some therapists were more effective when delivering one treatment over the other. Descriptively, 53% of therapists had similar outcomes across both groups (d < .20), whereas 47% had at least a small-sized treatment-type strength (d ≥ .20; range = 0.21-0.65). Results inform the personalization of treatment usage to the individual provider's effectiveness data. (PsycInfo Database Record (c) 2026 APA, all rights reserved).

Objective: This study seeks to investigate the cumulative incidence and risk factors of suicide attempts in an outpatient sample of adults diagnosed with major depressive disorder (MDD). Materials and Methods: This is a longitudinal study with 377 patients aged between 18 and 60 years. Those were diagnosed with MDD with no history of suicide attempts when they sought care at the Mental Health Outpatient Clinic of the Catholic University of Pelotas and evaluated again 3 years after. Participants were evaluated with the Mini International Neuropsychiatric Interview (MINI Plus) and answered instruments of clinical investigation and a sociodemographic questionnaire. Results: The cumulative incidence of suicide attempts in the sample was 10.1%. Youths aged up to 29 years (OR 2.23; 95% CI 1.13 to 4.64), with low schooling (OR 2.35; 95% CI 1.15 to 4.80), who suffered intense physical abuse during childhood (OR 2.77; 95% CI 1.31 to 5.84) and were at prior suicide risk (OR 3.39; 95% CI 1.56 to 7.37) were more likely to attempt suicide. Conclusion: The findings of this study may help health professionals identify depressed patients at greater risk for a first suicide attempt, supporting clinical decision and therapeutic planning.
