Abstract
ObjectiveDiscrepancies between self-reported and actigraphy sleep measures are common, producing ambiguity about which are better predictors of experimental pain outcomes. The current study tested if pain intensity during and situational pain catastrophizing following experimental pain were differentially predicted by self-reported or actigraphy sleep measures in patients with chronic temporomandibular disorder (TMJD) or healthy controls (HCs). MethodsForty patients with TMJD and 20 HCs completed self-report sleep measures (Pittsburgh Sleep Quality Index, PSQI; Insomnia Severity Index, ISI; PROMIS Sleep-Related Impairment [SRI] and Sleep Disruption [SD]), underwent an experimental pain induction consisting of four consecutive cold-water hand immersions, and provided pain intensity and situational pain catastrophizing ratings. Participants also wore an actigraphy watch and completed sleep diaries for seven days, which were averaged for actigraphic indices of total sleep time, sleep efficiency, wake after sleep onset, and self-reported sleep quality and restfulness. ResultsIndividuals with TMJD reported higher pain intensity during experimental pain (M = 65.81 vs. 47.77, p = .007) and self-reported worse sleep compared to HCs (all p's < 0.02, Cohen's D = 0.73–1.25). No group differences emerged for actigraphy measures (all p's > 0.05, Cohen's D = 0.05–0.53). Sleep variables did not interact with group to predict responses to experimental pain (all p's > 0.05). Across groups, PROMIS-SRI predicted pain intensity (β = 0.36, p = .008) and catastrophizing (β = 0.36, p = .009) after controlling for multiple comparisons, smoking, medications, and age. ConclusionSelf-reported sleep (but not actigraphy) measures differentiate patients with TMJD from HCs. Sleep-related interference may place people at particular risk for higher pain intensity and catastrophizing following experimental pain.
