Problem Solving Treatment Evidence Base

Of the multiple behavioral interventions in existence, only a few have been proven to work in fast-paced healthcare settings such as primary care. These include Problem Solving Treatment-Primary Care (PST-PC), Cognitive Behavioral Therapy (CBT), Interpersonal Counseling (IPC), and Behavioral Activation (BA).

PST-PC is the most widely used intervention to treat depression and anxiety in a primary care environment and has been found to significantly improve patient outcomes in a wide range of settings and patient populations. 

Numerous trials and studies have shown PST-PC to be an effective behavioral intervention that can greatly improve depression and anxiety symptoms. One such study published in the British Medical Journal found that “Problem solving treatment is an effective treatment for depressive disorders in primary care. The treatment can be delivered by suitably trained practice nurses or general practitioners.”

PST has been shown to be effective for depression among all adult populations (aged 18-100), including older adults with mild cognitive impairment.
