A clinical psychologist with a PsyD from CSPP at Alliant International University, Carla M. Payne conducts evaluations and individual therapy in downtown San Diego's Gaslamp Quarter at 121 Broadway. Her clinical scope covers co-occurring mental health conditions alongside cognitive and behavioral assessments for ADHD, anxiety, and anger-management disorders, an interdisciplinary caseload that often coordinates with somatic practitioners such as THRIVE Physical Therapy San Diego in Bankers Hill. The practice addresses complex diagnostic presentations where overlapping symptoms—attention deficits masking mood disorders, anxiety manifesting as chronic pain—require differential assessment before treatment planning. Payne's training as a clinical supervisor for doctoral psychology candidates means evaluation protocols follow current APA standards for structured clinical interviews and validated psychometric instruments, with coordinated medication oversight available through primary-care providers like Abisola A. Olulade, MD at Sharp Rees-Stealy Downtown. Comprehensive psychodiagnostic batteries incorporate the MMPI-2-RF, Conners CPT-3, and structured clinical interviews to differentiate ADHD subtypes from affective spectrum conditions with overlapping executive-function impairment.
