Abstract
Background Avoidance is the active process of trying to escape from or not experience situations, places, thoughts, or feelings. This can be done through behavioral or cognitive strategies, or more broadly, a combination of both, utilized in an attempt to disengage from private experiences referred to as experiential avoidance (EA). Avoidance is considered important in the development and maintenance of nonepileptic attack disorder (NEAD). This review aimed to understand avoidance in NEAD and evaluate its role as a contributory factor. Methods Fourteen articles were identified by searching Cumulative Index to Nursing and Allied Health (CINAHL), MEDLINE Complete, PsycINFO, and EMBASE and were combined in a narrative synthesis. Six of these articles were included in a meta-analysis comparing levels of EA for individuals with NEAD and healthy controls (HC), and four were included in a meta-analysis comparing EA in NEAD to epilepsy comparisons (EC). Conclusions Experiential avoidance appears to be a strategy that is used by a high proportion of the population with NEAD. The group with NEAD utilized significantly more avoidance compared with both the HC and EC. However, further research is needed to understand the extent and types of avoidance that are relevant.
