Evidence-based psychotherapy

Structured psychological treatment delivered by a trained professional whose efficacy for specific problems has been tested in controlled trials. Different therapies often show comparable average outcomes, which has fuelled debate about whether they work through techniques specific to each therapy or through common factors such as the therapeutic alliance. A review concluded that, because research on mechanisms has so far been correlational, no common or specific factor yet meets the criteria for an established working mechanism.
