Reports an error in “Assessing the safety and efficacy of prescribing psychologists in New Mexico and Louisiana” by Phillip M. Hughes, Joshua D. Niznik, Robert E. McGrath, Casey R. Tak, Robert B. Christian, Betsy L. Sleath and Kathleen C. Thomas (American Psychologist, 2025[Oct], Vol 80[7], 1019-1031; see record 2025-07510-001). In the article, the subheadings and N (%) values under “Psychologists versus psychiatrists” and “Psychologists versus primary care physicians” headings were transposed. The correct placements of headings and N (%) values are shown in the erratum. (The following abstract of the original article appeared in record 2025-07510-001). This study aimed to compare patient outcomes between prescribing psychologists, psychiatrists, and primary care physicians (PCPs). Private insurance claims (2005–2021; n = 307,478) were used to conduct an active comparator, new user longitudinal cohort study developed using target trial emulation. Inverse propensity for treatment weighting was used to adjust for baseline differences in a range of sociodemographic, clinical, and contextual patient factors. Differences in the 1-year rate of health care visits for adverse drug events (ADEs), psychiatric emergency department (ED) utilization, medication adherence, and psychotropic polypharmacy were identified between prescribing psychologists and the other provider types using doubly robust Cox proportional hazards models. Compared to patients of psychiatrists, patients of prescribing psychologists had a 24% lower rate of ADEs (95% CI [0.60, 0.96]), a 20% lower rate of psychotropic polypharmacy (95% CI [0.74, 0.86]), and similar rates of psychiatric ED utilization and medication nonadherence. Compared to patients of PCPs, patients of prescribing psychologists had 138% higher rates of psychiatric ED utilization (95% CI [1.67, 3.39]), 175% higher rates of psychotropic polypharmacy (95% CI [2.53, 2.99]), 28% lower rates of medication nonadherence (95% CI [0.66, 0.78]), and similar rates of ADEs. Using robust pharmacoepidemiological methods, we noted that among mental health specialists, prescribing psychologists appear to be as safe and efficacious as psychiatrists in a large sample of privately insured patients. Notable differences in safety and efficacy when compared to PCPs may be attributable to differences between specialty and primary care. Future research on prescribing psychologists should move toward studies of care quality. (PsycInfo Database Record (c) 2026 APA, all rights reserved)
