This study examined whether these cognitive factors influence CPM efficacy, and whether CPM magnitude differs between a parallel and sequential protocol.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Seventy\u2010two healthy adults participated in this randomised cross\u2010over study undergoing CPM evaluation, that is, pain pressure threshold assessment (=test stimulus) in response to hot water immersion (=conditioning stimulus (CS)) during four experimental protocols, that is, a neutral parallel protocol, a neutral sequential protocol, a sequential protocol with attentional focus on the CS\u2010induced pain intensity, and a sequential protocol with attentional distraction from the CS. Pain expectations were recorded before each protocol.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Focusing attention on the CS during CPM assessment resulted in smaller CPM magnitudes compared to no attentional manipulation or distracting from the CS. Distracting from the CS did not affect CPM magnitude compared to no attentional manipulation, nor did a priori expectations. Although CPM magnitudes were not statistically different between the parallel and sequential CPM protocol, a sequential protocol provides higher mean magnitudes and responder rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Since attentional focus on the CS reduces CPM efficacy, it is recommended to not rate the CS pain intensity during CS application to prevent a reduction of the inhibitory effect. Furthermore, a sequential protocol is recommended over a parallel protocol as a \u2018cleaner\u2019 representation of pain modulation free of attentional sources of biases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Significance Statement<\/jats:title>\n                    <jats:p>Conditioned pain modulation (CPM) is an important biomarker reflecting pain processing, however, there is a high variability in CPM response, making it important to gain insight into the influencing factors and mechanisms of CPM. The results of this study suggest that attentional focus on the conditioning stimulus influences CPM magnitude, whereas a distraction task and intrinsic a priori expectations do not. In both therapeutic and preventive approaches, it is of great interest for clinicians to positively address factors influencing CPM.<\/jats:p>\n                  <\/jats:sec>\n
