A core part of Portland Psychotherapy’s mission is the conduct of scientific research intended to help develop new treatments for people who are suffering. Most behavioral research is conducted in university settings and dependent on federal grant funding. Politics can therefore play a major role in determining what research gets funded, and sometimes this is at odds with scientific advancement. In contrast, Portland Psychotherapy uses a unique business model that provides funding for its research through its clinical services, which allows our researchers to function more independently.
Our research lab has dedicated research funding, space, equipment, and staff. Our internal grant program offers additional support to our researchers. We also host a postdoctoral fellowship affording research opportunities, and offer mentorship to volunteer research assistants working on undergraduate and graduate degrees.
Purpose and Aims
We use contextual behavioral science and affective science to find new and more effective ways of alleviating psychological suffering and helping people live richer and fuller lives. To do this, we conduct both basic and applied research with the aim of helping the scientific community better describe, predict, and influence behavior with precision, scope, and depth. We also aim to create an environment that nurtures the personal and professional development of behavioral scientists.
Our ongoing research includes a variety of projects relevant to the following topic areas:
- Psychedelics and MDMA-assisted psychotherapy
- Stigma and substance use disorder
- The effects of social signaling,interpersonal behavior, emotion regulation, and emotion in highly shame prone and self-critical people
- Processes of change relevant to Acceptance and Commitment Therapy and Radically Open Dialectical Behavior Therapy
- Processes of therapeutic change related to self-compassion, shame, and self-criticism
Publications from the Lab
The findings of our researchers are shared with the larger scientific community and the world through publications (listed here) and through presentations at scientific conferences.
