Context in psychotherapy refers to the broader framework that encompasses all relevant factors within which the understanding of the client's experiences, behaviors, and problems develops. This framework includes current circumstances, past experiences, interpersonal relationships, as well as cultural and social norms that together shape the client's worldview and their interaction with the environment. Understanding this context enables the therapist to perceive the complexity and dynamism of the client's psychological life and to tailor the therapeutic approach to the individual needs of the client.
