Problem Management Plus (PM+) in Chile: a Pilot Randomized Controlled Trial of a Psychological Transdiagnostic Intervention Delivered in Primary Health Care

"Problem Management Plus (PM+) will be delivered according to the Spanish version of the WHO protocol (OMS, 2016).~PM+ is a low-intensity, transdiagnostic psychological intervention based on Cognitive Behavioral Therapy (CBT). The protocol incorporates evidence-based strategies, including problem-solving, stress management, behavioral activation, and accessing social support.~The intervention consists of five individual 90-minute sessions provided by healthcare professionals without previous expertise in mental health care (WHO, 2018). PM+ helpers will be supervised by master trainers specifically trained for Chile.~Two systematic reviews have demonstrated the effectiveness of PM+ in reducing symptoms of common mental disorders, such as depression and anxiety (Schäfer et al., 2023) and specific symptoms of post-traumatic stress (Akhtar et al., 2022)."
