Experiential avoidance (EA), or attempts to escape unwanted internal experiences (e.g., thoughts, feelings) at the expense of long-term commitment to personal values, has wide-reaching effects for a variety of socially important problems. This symposium will explore EA in both its existing and potential forms of measurement. The first presentation will cover an analogue study which measures levels of EA by exposing adult participants to aversive sounds in the context of delayed reinforcement. The second presenter will discuss how an existing measure, the Avoidance and Fusion Questionnaire, was used to investigate avoidance as a moderation of sexual prejudice and political affiliation among a college student sample. Both studies found that EA could be measured reliably. The results of the first study prove useful to an Acceptance and Commitment Therapy model, as choices changed from smaller, sooner reinforcement to larger, later reinforcement - mapping on to valuing. The hypothesized moderating role of EA in the relationship between political affiliation and sexual prejudice investigated in the second study was found to be insignificant, and the authors will discuss potential reasons for this finding. Measurement limitations and future directions will be covered.

Experiential avoidance, which can be functionally defined as choosing short-term negative reinforcement over long-term values-oriented positive reinforcement, has been argued to be at the core of a large variety of socially important problems. Relatively little previous laboratory research has studied these functional relations and this study attempted to develop a laboratory preparation that pits shorter-term avoidance over longer-term positive reinforcement. Participants were exposed to choices between avoidance of an aversive sound (i.e., immediate, smaller negative reinforcement) or listening to an aversive sound for a period of time and accumulating money (i.e., delayed, larger positive reinforcement). Three experiments were conducted that evaluated varying magnitudes of delays to and the value of the positive reinforcer, in order to identify the point at which individual participants’ choices changed from the smaller, sooner reinforcer to the larger later reinforcer and vice versa. The potential applicability of this model is discussed as it relates to behavior problems that appear to involve experiential avoidance at their core. In addition, the implications for evaluating components of acceptance and commitment therapy (ACT) are discussed.
