Medical interventions are quite efficacious in reducing pain levels. However, changes in physical and mental health status after medical interventions are not proportional. In the past decades, rational/irrational beliefs, especially catastrophizing, have contributed to a better understanding of the pain experience. This study explores whether pain reduction efforts are more beneficial for individuals scoring high in rational thinking (moderation). Methods: the study design was longitudinal. Patients were assessed twice, 2 weeks prior to the start of medical treatment at the pain clinic and 6 months after. A total of 163 patients with heterogeneous pain (mostly low back and neck pain) participated in the study. Their mean age was 58.74 years (SD = 14.28) and 61.3% were female. Results: Overall, there was a reduction in pain intensity (t = 4.25, p < 0.001, d = 0.32). An improvement in physical functioning (t = 4.02, p < 0.001, d = 0.19), but not mental health (t = -0.66, p = 0.511, d = 0.11) was also observed. In the regression analyses, a decrease in pain intensity was moderately associated with improved physical health (beta = 0.87, t = 4.96, p < 0.001, R-2 change = 0.177). This association was found to be moderated by frustration tolerance (beta = -0.49, t = -2.80, p = 0.006, R-2 change = 0.039). Specifically, post hoc analyses indicated that changes in pain intensity only correlated with changes in physical health when patients reported high frustration tolerance levels (r = 0.47, p = 0.006, M = 7, n = 32), but not when patients were intolerant to frustration (r = 0.28, p = 0.078, M = 17, n = 41). Conclusion: the results suggest that frustration tolerance may render adaptive by facilitating the positive effect that a reduction in pain intensity has on physical health status. The study findings are discussed in the context of personalized therapy with an emphasis on how to maximize the effectiveness of current interventions for pain. 000079591 536__ $$9info:eu-repo/grantAgreement/ES/MEC/FPU-AP2010-5585 000079591 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000079591 590__ $$a2.067$$b2019 000079591 591__ $$aPSYCHOLOGY, MULTIDISCIPLINARY$$b45 / 138 = 0.326$$c2019$$dQ2$$eT1 000079591 592__ $$a0.914$$b2019 000079591 593__ $$aPsychology (miscellaneous)$$c2019$$dQ1 000079591 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000079591 700__ $$aCamacho-Guerrero, Laura 000079591 700__ $$0(orcid)0000-0002-7293-318X$$aOsma, Jorge$$uUniversidad de Zaragoza 000079591 700__ $$aSuso-Vergara, Santiago 000079591 700__ $$aGallardo-Pujol, David 000079591 7102_ $$14009$$2680$$aUniversidad de Zaragoza$$bDpto.
