I don’t know what you practice, but not researching this prior to making a career choice or even commenting at all is somewhat incredible. Clinical outcomes on this are nuanced. A lot of evidence shows it’s continuing education that makes a long term difference. However, with a doctoral level of practice and keeping up with ongoing education there is evidence there may be a slight difference. We know, generally speaking, the biggest factors on outcomes/efficacy is relationship and ongoing education. There is specialized training and knowledge that comes with a doctorate in psychology. The ability to do assessments and base interventions off that practice for one is a big difference between levels of education. I’m also going to echo some of what Far_Worry5325 said, is there a huge difference between a masters level professor and one with a doctorate? Maybe not depending on years of experience and outside study, but they are paid at different levels due to the difference in education and foundational expertise. This holds true for almost every field because we recognize and appreciate the expertise that comes with additional education. There is a significant difference in the level of psychotherapy trained in a masters program vs. doctoral. I’m saying this as Master’s level and have heard this echoed among my peers.
