► We examine positive traits, pain catastrophizing and pain report. ► Participants completed an experimental pain stimulus, a cold pressor task. ► Associations found between positive traits, pain catastrophizing and pain report. ► Pain catastrophizing mediated the relationship between positive traits and pain. The present study examined the association between positive traits, pain catastrophizing, and pain perceptions. We hypothesized that pain catastrophizing would mediate the relationship between positive traits and pain. First, participants ( = 114) completed the Trait Hope Scale, the Life Orientation Test-Revised, and the Pain Catastrophizing Scale. Participants then completed the experimental pain stimulus, a cold pressor task, by submerging their hand in a circulating water bath (0 °C) for as long as tolerable. Immediately following the task, participants completed the Short-Form McGill Pain Questionnaire (MPQ-SF). Pearson correlation found associations between hope and pain catastrophizing ( = −.41, 〈 .01) and MPQ-SF scores ( = −.20, 〈 .05). Optimism was significantly associated with pain catastrophizing ( = −.44, 〈 .01) and MPQ-SF scores ( = −.19, 〈 .05). Bootstrapping, a non-parametric resampling procedure, tested for mediation and supported our hypothesis that pain catastrophizing mediated the relationship between positive traits and MPQ-SF pain report. To our knowledge, this investigation is the first to establish that the protective link between positive traits and experimental pain operates through lower pain catastrophizing.
