Common factors theory, a theory guiding some research in clinical psychology and counseling psychology, proposes that different approaches and evidence-based practices in psychotherapy and counseling share "common factors" that account for much of the effectiveness of a psychological treatment.
 This is in contrast to the view that the effectiveness of psychotherapy and counseling is best explained by specific or unique factors (notably, particular methods or procedures) that are suited to treatment of particular problems.
 According to one review, "it is widely recognized that the debate between common and unique factors in psychotherapy represents a false dichotomy, and these factors must be integrated to maximize effectiveness".
 In other words, "therapists must engage in specific forms of therapy for common factors to have a medium through which to operate".
 Common factors is one route by which therapists are attempting to integrate psychotherapies.
