COSTA, Joana  and  GOUVEIA, José Pinto. Pain acceptance: Psychometric approach to the Chronic Pain Acceptance Questionnaire in a Portuguese sample with chronic pain. Psicologia [online]. 2009, vol.23, n.1, pp.103-126. ISSN 0874-2049.  https://doi.org/10.17575/rpsicol.v23i1.319.

The present study presents the psychometric properties of the Portuguese version of The Chronic Pain Acceptance Questionnaire (McCracken, Vowles & Eccleston, 2004; translated and adapted by Pinto Gouveia & Costa, 2008). This self-report questionnaire assesses the willingness to experience pain and life activities regardless of pain, in 104 Portuguese adults with chronic pain. Factor analysis showed a two factors structure which explained 51% of the total variance. The structure was similar to the original model and had adequate reliability. Convergent validity supported the expected relations between pain acceptance, psychopathology, self compassion, experiential avoidance and rumination and supported the contribution of this construct in explaining depression, anxiety and stress. The results obtained also contributed for the discriminative power of this measure. Moreover, results offered empirical support to conceptual models based on the Acceptance and Commitment Therapy (ACT: Hayes, Strosahl & Wilson, 1999) and reinforced the existing literature about its application to chronic pain.
