A Taxometric Analysis of Experiential Avoidance.

Experiential avoidance, a trait-like construct referring to the tendency to rigidly avoid or change unpleasant internal experiences stemming from an unwillingness to experience them, is believed to contribute to the development and maintenance of various forms of psychopathology. Despite significant research on this construct, it remains unclear whether experiential avoidance is dimensional or categorical at the latent level. The current study examined the latent structure of experiential avoidance using three taxometric analytic approaches (MAXimum Eigenvalue, Mean Above Minus Below A Curve, Latent-Mode Factor Analysis) applied to data from two independent samples and using three widely used measures of experiential avoidance. The first sample (n = 922) completed the Multidimensional Experiential Avoidance Questionnaire (Gámez, Chmielewski, Kotov, Ruggero, & Watson, 2011), while the second sample (n = 615) completed the Brief Experiential Avoidance Questionnaire (Gámez et al., 2014) and Acceptance and Action Questionnaire-II (Bond et al., 2011). Across both samples and all three measures, experiential avoidance exhibited a dimensional structure. The clinical and research implications of this finding for experiential avoidance are discussed.
