CAD-R. Coping chronic pain questionnaire: confirmatory factorial analysis. Are there individual differences in sex, age and type of pain?

Abstract

Introduction: A review of the CAD-R (Cuestionario de afrontamiento al dolor reducido)(1) is presented in a sample of 4389 patients diagnosed with chronic pain derived from a spanish multicenter study (2). Material and Method: The factorial structure is analyzed by exploratory factor analysis (EFA) and confirmatory (CFA), as well as reliability (internal consistency and test-retest at three months, the latter of which is 2825 patients). Four models are tested proving that correlated first-order strategies are those that provide better adjustment indices. Results: Both internal consistency and test-retest indices are acceptable. Discussion: CAD-R appears as an instrument that presents good reliability and a factorial structure of six first-order strategies.
