About Problem Solving Treatment

Problem Solving Treatment (PST), also known as Problem-Solving Treatment – Primary Care (PST-PC), teaches and empowers patients to solve the here-and-now problems contributing to their depression and helps increase self-efficacy. 

Developed for use by medical professionals in primary care settings, an extensive evidence base shows that PST can effectively be provided in a wide range of settings and with a variety of providers and patient populations. 

As part of a treatment plan, PST typically involves six to ten sessions, depending on the patient’s needs. The first appointment is approximately one hour long (this can be split into two separate ½ hour sessions if scheduling an hour is difficult) because it includes psychoeducation and an introduction to the PST model before PST is applied. Subsequent appointments are 30 minutes long.

For practices implementing an evidence-based collaborative care program, the ability to provide psychotherapy as part of a treatment plan is encouraged. 

Clinician PST Training & Certification

The AIMS center provides training and certification in PST for those who are part of an integrated care team or for any clinician wishing to provide behavioral interventions. Licensed providers such as licensed social workers, registered nurses, and psychologists are eligible to receive training and to become certified in PST. Previous experience or training in mental health is not a prerequisite for PST training and certification.

The certification process typically requires between 19 to 22 hours of clinician time over the course of seven months and requires demonstration of mastery of the technique. If you would like to register for training, please contact

Continuing Education

PST training provided by the AIMS Center is approved by the National Association of Social Workers and the American Psychological Association for four continuing education contact hours toward continuing education licensure requirements.
