She is currently completing an NIMH R34-funded clinical trial of a telehealth adaptation of CBT for individuals at CHR and developing digital therapeutics such as RELATED (Resilience to Adversity Through Education and Dialogue), which helps caregivers learn CBT strategies to support relatives with psychotic symptoms. Her research also focuses on early identification of individuals at CHR and those experiencing a first episode of psychosis (FEP), pathways to care, and the role of clinician-patient communication in treatment engagement. Her NIMH R01-funded study, Early Stage Identification and Engagement to Reduce DUP (EaSIE), aims to reduce the duration of untreated psychosis through systematic screening and an innovative communication model (ComPsych) designed to enhance how psychosis and CHR are discussed with patients and families. To support broad dissemination of CBT for the treatment and prevention of psychosis, Dr. Landa has developed training programs and provides CBTp training to clinicians across the U.S. and internationally.
