Experiential avoidance

Experiential avoidance (EA) has been broadly defined as attempts to avoid thoughts, feelings, memories, physical sensations, and other internal experiences—even when doing so creates harm in the long-run. The process of EA is thought to be maintained through negative reinforcement—that is, short-term relief of discomfort is achieved through avoidance, thereby increasing the likelihood that the behavior will persist. Importantly, the current conceptualization of EA suggests that it is not negative thoughts, emotions, and sensations that are problematic, but how one responds to them that can cause difficulties. In particular, a habitual and persistent unwillingness to experience uncomfortable thoughts and feelings (and the associated avoidance and inhibition of these experiences) is thought to be linked to a wide range of problems.

EA has been popularized by recent third-wave cognitive-behavioral theories such as acceptance and commitment therapy (ACT). However, the general concept has roots in many other theories of psychopathology and intervention.

Defense mechanisms were originally conceptualized as ways to avoid unpleasant affect and discomfort that resulted from conflicting motivations. These processes were thought to contribute to the expression of various types of psychopathology. Gradual removal of these defensive processes are thought to be a key aspect of treatment and eventually return to psychological health.

Process-experiential therapy merges client-centered, existential, and Gestalt approaches. Gestalt theory outlines the benefits of being fully aware of and open to one's entire experience. One job of the psychotherapist is to "explore and become fully aware of [the patient's] grounds for avoidance" and to "[lead] the patient back to that which he wishes to avoid" (p. 142). Similar ideas are expressed by early humanistic theory: "Whether the stimulus was the impact of a configuration of form, color, or sound in the environment on the sensory nerves, or a memory trace from the past, or a visceral sensation of fear or pleasure or disgust, the person would be 'living' it, would have it completely available to awareness…he is more open to his feelings of fear and discouragement and pain...he is more able fully to live the experiences of his organism rather than shutting them out of awareness."
