Psychological flexibility is a construct developed in the area of contextual behavioral science (CBS). The core of psychological flexibility is the ability to freely choose actions that are in accordance with one's own goals and values, regardless of what thoughts, emotions, and impressions are triggered by those activities (Hayes, Strosahl, Wilson, 2013). The concept of psychological flexibility has been introduced in the model comprising six key processes that promote its development and six opposite processes which lead to a lack of psychological flexibility. This model is the basis for the analysis of mental health and psychopathology as a part of Acceptance and Commitment Therapy (ACT; Hayes et al., 2013) that belongs to the third wave of cognitive-behavioral therapies (Hayes, 2004). The psychological flexibility model can also be the basis for the analysis of psychological functioning in other areas. This book presents the results of research focused on Polish adaptation and validation of psychological tools measuring of all six psychological flexibility processes: 1) Multidimensional Experiential Avoidance Questionnaire-30, a measure of experiential avoidance. 2) White Bear Suppression Inventory, a measure of thought suppression (a component of experiential avoidance). 3) Freiburg Mindfulness Inventory, a measure of flexible contact with the present moment. 4) Cognitive Fusion Questionnaire, a measure of cognitive fusion. 5) Self Experiences Questionnaire, a measure of self as a context. 6) Valuing Questionnaire, a measure of values. 7) Committed Action Questionnaire, a measure of committed action. Each of seven chapters addressing those tools includes a theoretical description of the measured construct, information on the origins and applicability of a given scale, a description of the procedure, results of Polish validation tests, and tips on how to apply and interpret the results obtained, as well as a test sheet that can be used in research or psychological practice. The adapted tools have good psychometric properties and form a coherent and complete set of methods that measure related constructs of psychological flexibility. They can be applied as a measure of key processes of the psychological flexibility model in research on general and clinical groups, in research evaluating the effectiveness of psychological interventions based on the psychological flexibility model and also in therapeutic work with patients.
