Article: Coping with chronic musculoskeletal pain in Portugal and in the United States: a cross-cultural study.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to examine the associations between coping and adjustment to chronic pain in a sample of patients from Portugal and to discuss the findings with respect to published findings from two studies using patients from the United States. Two brief measures of pain coping were translated and administered with measures of physical and psychological functioning to a sample of Portuguese patients. Analyses examined the associations among the study variables and compared the results with published data from two patient samples from the United States. One hundred seventeen individuals with chronic musculoskeletal pain. Portuguese translations of brief versions of the Coping Strategies Questionnaire and Chronic Pain Coping Inventory and criterion measures of pain intensity, pain interference, and depression. Statistically significant positive associations were found between measures of patient dysfunction and catastrophizing, praying/hoping, guarding, asking for assistance, and support seeking; and negative associations were found between the criterion measures and ignoring sensations, coping self-statements, and increasing behavioral activities. Mean differences between the Portuguese and US samples in the coping scales were found for nine of the 15 coping scales. The results support the reliability and validity of the translated Coping Strategies Questionnaire and Chronic Pain Coping Inventory and also indicate a number of similarities, but also some interesting differences, in the findings from the Portuguese vs US samples, suggesting that there may be cultural differences in how people cope with pain.Pain Medicine 08/2011; 12(10):1470-80. · 2.35 Impact Factor -
Article: Psychometric properties of the portuguese version of the Pain Self-Efficacy Questionnaire.

ABSTRACT: This study sought to translate and evaluate the psychometric properties of a European Portuguese version of the Pain Self-Efficacy Questionnaire (P-PSEQ), in order to enable its use in clinical and cross-cultural studies. The Pain Self-Efficacy Questionnaire was translated into European Portuguese and then back-translated into English. A consensus version of the translated version was pre-tested with a pilot sample, followed by cognitive debriefing, resulting in a final version of the measure. A convenience sample of 174 Portuguese adults with chronic musculoskeletal pain completed the Portuguese Pain Self-Efficacy Questionnaire (P-PSEQ) and criterion measures of pain intensity (Numerical Ratings Scale), pain interference (Portuguese Brief Pain Inventory Interference Scale), quality of life and general health (SF-12), and psychological functioning (Hospital Anxiety and Depression Scale). Cronbach's alpha and composite reliability coefficients were computed as measures of reliability, and confirmatory factor analysis was performed. Pearson correlation coefficients between the P-PSEQ score and the criterion measures were computed to evaluate the construct validity of the scale. The P-PSEQ demonstrated good to excellent reliability (Cronbach's alpha = 0.88 and Composite reliability = 0.92), and showed moderately strong associations with the criterion measures in the hypothesized directions, supporting its construct validity. Additionally, the confirmatory factor analysis supported a single factor solution, as hypothesized. The findings provide strong support for the reliability and validity of the P-PSEQ. Research is needed to determine the responsivity of the P-PSEQ and to establish the generalizability of the results in other samples of Portuguese patients with chronic pain.Acta reumatologica portuguesa 07/2011; 36(3):260-7. · 0.55 Impact Factor
