- COPAHS Study: protocol of a randomised experimental study comparing the effects of hypnosis, mindfulness meditation, and spiritual practices on experimental pain in healthy adultsPublication . Ferreira-Valente, Maria Alexandra; Pimenta, Filipa; Costa, Rui Miguel; Day, Melissa; Pais-Ribeiro, José; Jensen, Mark P.There has been an increasing interest in studying the potential benefits of so-called complementary and alternative approaches for pain management, such as hypnosis and mindfulness-based interventions. More recently, researchers have been interested in studying the effects of spiritual practices on pain experience as well. These practices may increase pain tolerance, result in a positive re-appraisal of pain and influence other psychological variables that are known to be associated with pain experience. The purpose of this study is to evaluate and compare the immediate effects of self-hypnosis, mindfulness meditation, and a spiritual intervention relative to a control condition for increasing pain tolerance and reducing pain intensity and pain-related stress, in response to experimental painful stimulation.
- Coping with chronic musculoskeletal pain in Portugal and in the United States: A cross-cultural studyPublication . Valente, Maria Alexandra Ferreira; Ribeiro, José Luís Pais; Jensen, Mark P.; Almeida, RubenObjective. 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. Design. 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. Participants. One hundred seventeen individuals with chronic musculoskeletal pain. Outcome Measures. 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. Results. 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. Conclusions. 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.
- Coping, depression, anxiety, self-efficacy and social support: Impact on adjustment to chronic painPublication . Valente, Maria Alexandra Ferreira; Ribeiro, José Luís Pais; Jensen, Mark P.Pain is a multidimensional, unique, and private experience. Contemporary biopsychosocial models of chronic pain hypothesize a key role for psychosocial factors as contributing to the experience of and adjustment to chronic pain. The psychosocial factors that have been most often examined as they relate to chronic pain include coping responses, attributions (such as self-efficacy), mood (including depression and anxiety), and social support. Knowledge concerning the relative importance of each of these factors to adjustment is necessary for understanding and developing effective psychosocial interventions. This article reviews the literature concerning the associations between psychosocial factors and adjustment to chronic pain, with a focus on coping, attributions, mood, and social support. Overall, the findings of this research are consistent with biopsychosocial models of chronic pain, and support continued research to help identify the causal relationships among key psychosocial variables and adjustment. ------ RESUMEN ------ El dolor es una experiencia multidimensional, única, y privada. Los modelos biopsicosociales contemporáneos de dolor crónico hipotetizan que los factores psicosociales ejercen un papel clave tanto en la configuración de la experiencia de dolor crónico como en el proceso de ajuste de quien lo sufre. Los factores psicosociales más estudiados incluyen: el afrontamiento, las atribuciones (como la autoeficacia), el estado afectivo (tanto la depresión como la ansiedad) y el apoyo social. Conocer la importancia relativa de cada uno de éstos en los procesos de ajuste a la experiencia del dolor crónico es necesario para entender y desarrollar intervenciones psicosociales eficaces. Este artículo revisa la literatura sobre la relación entre factores psicosociales y procesos de ajuste al dolor crónico, especialmente afrontamiento, atribuciones, estado de ánimo, y apoyo social. En general, las conclusiones de este trabajo son compatibles con los modelos biopsicosociales de dolor crónico, y sugieren continuar las investigaciones para identificar las relaciones causales entre ciertas variables psicosociales y el ajuste al dolor crónico.
- Further validation of a portuguese version of the brief pain inventory interference scalePublication . Valente, Maria Alexandra Ferreira; Ribeiro, José Luís Pais; Jensen, Mark P.Chronic pain is a significant health problem which interferes with patients daily functioning and quality of life. Valid and reliable measures of pain-related interference are needed to provide adequate care to patients and monitor changes in pain and functioning over time. This study sought to evaluate the reliability and validity of a Portuguese version of the Brief Pain Inventory (P-BPI) interference scale. Two hundred and fourteen patients with chronic musculoskeletal pain completed the P-BPI, 0-10 NRS of pain intensity, Short Form-12 Health Status Questionnaire (SF-12), Hospital Anxiety and Depression Scale (HADS). The P-BPI demonstrated excellent internal consistency (Cronbach’s alpha = .91) and showed moderate associations with the criterion measures (all rs .30 or larger), supporting its construct validity. Confirmatory factor analysis of the P-BPI items yielded a single factor, further supporting its construct validity. The results provide strong support for the reliability and validity of the P-BPI interference scale.
- Pain diagnosis, pain coping, and function in individuals with chronic musculoskeletal painPublication . Valente, Maria Alexandra Ferreira; Garcia, Inês; Ribeiro, José Luís Pais.; Jensen, Mark P.Purpose: Research supports a role for coping responses in adjustment to chronic pain. However, it is likely that some coping responses play a larger role in adjustment to pain for some individuals than others. The identification of the factors that moderate the association between coping responses and pain-related outcomes has important clinical implications. This study sought to determine if musculoskeletal pain diagnosis moderates the associations between eight pain-coping responses and both pain and function. Patients and Methods: A non-probabilistic sample of 323 persons with different chronic musculoskeletal pain conditions completed measures of pain intensity, physical function, psychological function, and pain-coping responses. Results: With only one exception, the frequency of use of pain-coping responses was not associated with pain diagnosis. Statistically significant moderation effects of pain diagnosis on the association between coping and pain outcomes were found for two coping responses: 1) support seeking when predicting pain intensity, and 2) resting when predicting both physical and psychological function. Conclusion: The findings indicate that coping responses tend to play a similar role in patients' pain and function across different musculoskeletal pain conditions, with some important exceptions. If the findings are found to replicate in other samples, they would have important implications for determining when psychosocial pain treatments might (and when they might not) need to be adapted for specific diagnostic groups.
- Pain-related beliefs, coping, and function: An observational study on the moderating influence of country of originPublication . Ferreira-Valente, Maria Alexandra; Sharma, Saurab; Chan, Joy; Bernardes, Sónia F.; Ribeiro, J.; Jensen, Mark P.Chronic pain is a multidimensional experience and pain treatments targeting psychosocial factors reduce pain and improve function. These treatments often overlook the sociocultural factors that influence pain and the psychological factors associated with function in people with chronic pain. Although preliminary findings suggest that cultural background may influence pain and function via their effects on beliefs and coping, no previous study has directly tested if the country of origin moderates the associations between these psychological factors and pain and function. This study sought to address this knowledge gap. Five hundred sixty-one adults with chronic pain, born and living in the USA (n = 273) or Portugal (n = 288), completed measures of pain, function, pain-related beliefs, and coping. Between-country similarities were found in the endorsement of beliefs related to disability, pain control, and emotion, and in asking for assistance, task persistence, and coping self-statement responses. Portuguese participants reported greater endorsement of harm, medication, solicitude, and medical cure beliefs, more frequent use of relaxation and support seeking, and less frequent use of guarding, resting, and exercising/stretching. In both countries, disability and harm beliefs and guarding responses were associated with worse outcomes; pain control and task persistence were associated with better outcomes. Six country-related small effect-size moderation effects emerged, such that task persistence and guarding are stronger predictors of pain and function in adults from the USA, but pain control, disability, emotion, and medication beliefs are more important in adults from Portugal. Some modifications may be needed when adapting multidisciplinary treatments from one country to another. Perspective: This article examines the similarities and differences in beliefs and coping endorsed by adults with chronic pain from 2 countries, and the potential moderation effects of country on the associations between these variables and pain and function. The findings suggest that some modifications may be needed when culturally customizing psychological pain treatments.
- The portuguese 35-item survey of pain attitudes applied to portuguese women with endometriosisPublication . Valente, Maria Alexandra Ferreira; Garcia, Inês Queiroz; Rosa, Ana Marques; Pereira, Anabela; Ribeiro, José Luis Pais; Jensen, Mark P.Background and aims endometriosis is a gynecologic recurring persistent condition affecting from 8% to 15% of premenopausal women worldwide. About 80% of women with endometriosis have at least one form of chronic pain - a multidimensional experience influenced by a number of psychosocial factors, including pain-related beliefs. The Survey of Pain Attitudes is the most commonly used measure of pain-related beliefs. This study aims to evaluate the psychometric properties of a Portuguese version of a brief version of the SOPA (the SOPA-35) in a sample of Portuguese women with Endometriosis. Methods A sample of 199 Portuguese women with Endometriosis provided demographic and pain history information, and completed a Portuguese version of the SOPA-35 and measures of pain intensity, disability, and psychological function. Analyses were performed to evaluate the factor structure of the Portuguese SOPA-35 items as well as the internal consistency, composite reliability, convergent validity, and concurrent validity of the scale scores. Results Confirmatory factor analysis supported a six-factor solution for a 19-item version of the Portuguese version of the Survey of Pain Attitudes (SOPA-19-P). The six scales evidenced marginal to good reliability (Cronbach's alphas: between 0.60 and 0.84; composite reliability: between 0.61 and 0.84). Four scales evidenced acceptable to good convergent validity (AVE: between 0.51 and 0.63). The findings also supported the concurrent validity of the SOPA-19-P. Conclusions The results support the use of the Portuguese SOPA-19-P for research and clinical purposes with Portuguese women in chronic pain due to endometriosis. Future research is warranted to further develop a European Portuguese version of SOPA. Implications The findings provide psychometric information about the SOPA-19-P. The results are helpful to researchers wishing to study the role of pain-related beliefs and their association with adjustment and treatment outcomes in women with chronic pain due to endometriosis.
- The role of perfectionistic self-presentation in pediatric painPublication . Sánchez-Rodríguez, Elisabet; Ferreira-Valente, Maria Alexandra; Pathak, Anupa; Solé, Ester; Sharma, Saurab; Jensen, Mark P.; Miró Canals, JordiThis study sought to better understand the associations between perfectionistic self-presentation and measures of pain intensity, pain catastrophizing, pain interference, and fatigue in children and adolescents with pain. In the study, 218 adolescents responded to measures of perfectionistic self-presentation (i.e., perfectionistic self-promotion, nondisplay of imperfection and nondisclosure of imperfection), pain intensity, pain catastrophizing, pain interference, and fatigue. Four hierarchical regression analyses and three mediation analyses were conducted. Our results showed that perfectionistic self-promotion was significantly and independently associated with pain intensity and that nondisplay of imperfection was significantly and independently associated with pain catastrophizing, pain interference, and fatigue. Nondisclosure of imperfection was not significantly associated with any criterion variable. Pain catastrophizing mediated the association between both perfectionistic self-presentation and nondisplay imperfection and pain interference but not between nondisclosure of imperfection and pain interference. The findings provide new information about the role of perfectionistic self-presentation in children and adolescents' experience of pain. These findings, if replicated, support perfectionism as a potential target of pain treatment in young people.
- Validity of four pain intensity rating scalesPublication . Valente, Maria Alexandra Ferreira; Ribeiro, José Luís Pais; Jensen, Mark P.The Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), Verbal Rating Scale (VRS), and the Faces Pain Scale-Revised (FPS-R) are among the most commonly used measures of pain intensity in clinical and research settings. Although evidence supports their validity as measures of pain intensity, few studies have compared them with respect to the critical validity criteria of responsivity, and no experiment has directly compared all 4 measures in the same study. The current study compared the relative validity of VAS, NRS, VRS, and FPS-R for detecting differences in painful stimulus intensity and differences between men and women in response to experimentally induced pain. One hundred twenty-seven subjects underwent four 20-second cold pressor trials with temperature order counterbalanced across 1 C, 3 C, 5 C, and 7 C and rated pain intensity using all 4 scales. Results showed statistically significant differences in pain intensity between temperatures for each scale, with lower temperatures resulting in higher pain intensity. The order of responsivity was as follows: NRS, VAS, VRS, and FPS-R. However, there were relatively small differences in the responsivity between scales. A statistically significant sex main effect was also found for the NRS, VRS, and FPS-R. The findings are consistent with previous studies supporting the validity of each scale. The most support emerged for the NRS as being both (1) most responsive and (2) able to detect sex differences in pain intensity. The results also provide support for the validity of the scales for use in Portuguese samples.
