I'm a master's level therapist in the US. Sure, there is a difference between a therapist and a psychologist, but they also are trained to do different things. Psychologists, generally speaking, do testing and evaluation. Depending on your condition, this may be totally irrelevant. Or maybe it is, depends on what you're dealing with. But I would not look at level of education, but rather the rapport you establish with them, their personality, their theoretical orientation. So much of this profession has to do with the relationship. Level of education is only one of many factors to use in making this decision. It's certainly not the most important. But like I said, depends on what you are seeing a therapist for.
