The Everyday Psychological Inflexibility Checklist (EPIC)

The Everyday Psychological Inflexibility Checklist or EPIC seeks to measure aspects of psychological inflexibility in an everyday context. The measure was designed to form one small part of Contextual Behavioural Science’s (CBS) aspirations to meet some wider challenges of the human condition such as poverty, inequality, climate change and environmental destruction. Unlike the Acceptance and Action Questionnaire version 2, (AAQ-II), the items of the EPIC make no reference to pain, fear and worry.

The EPIC contains seven items spread across two factors: Avoidance (items: 1, 3, 5 & 7) and Behavioural Rigidity (items 2, 4 & 6). Participants are asked to rate how true each item is for them in their everyday life (no time frame given). Items are rated on a 7 point Likert-type scale ranging from (1) never true to (7) always true. Higher scores indicate higher levels of psychological inflexibility.

The preliminary psychometric properties of the EPIC are detailed in a paper, containing four studies, published in the Journal of Contextual Behavioural Science (JCBS, see here) for more details.
