Committed action: an application of the psychological flexibility model to activity patterns in chronic pain.

UNLABELLED: Whether a person with chronic pain avoids activity, persists with activity, or overexerts himself or herself is considered important to the quality of his or her daily functioning. However, results from studies of these activity patterns have not always yielded clear and consistent findings. It is suggested that applying the psychological flexibility model to activity patterns may clarify and integrate research in this area. Psychological flexibility is defined as the ability to persist or to change behavior in a setting of competing psychological influences, guided by goals and dependent on what the situation at hand affords. One aspect of psychological flexibility that appears pertinent to chronic pain is called committed action. Committed action is essentially goal-directed, flexible persistence. The purpose of the current study was to develop a measure of committed action, the committed action questionnaire (CAQ), in people seeking treatment for chronic pain (N = 216), to examine preliminary reliability and validity, and to test how well a summary score from the measure is able to predict patient health and functioning. Results generally support the internal consistency of the CAQ and show that it is correlated with another established component of psychological flexibility. In regression analyses the CAQ was able to account for significant variance in depression, social functioning, mental health, vitality, and general health, beyond the contributions of pain and acceptance of pain. PERSPECTIVE: The psychological flexibility model may be useful for understanding patterns of behavior in relation to chronic pain. It appears possible to assess a process in this model called committed action, and this process appears related to important aspects of functioning.
