This study sought to investigate the relationship between cognitive functioning and chronic pain conditions in individuals seeking detoxification treatment. Previous research suggests that individuals with a chronic pain condition demonstrate neuropsychological impairment in attentional capacity and processing speed (Hart, Martelli, & Zasler, 2000). Pain catastrophizing has been found to predict the likelihood of cognitive complaints in participants with a diagnosed chronic pain condition (Roth, Geisser, Theisen-Goodvich, & Dixon, 2005). Further research suggests that those who self-report more somatic awareness have worse cognitive performance (Eccleston, Crombez, Aldrich, & Stannard, 1997). This study hypothesizes that having a chronic pain condition will moderate the relationship between pain catastrophizing and cognitive functioning, such that those with a chronic pain condition will demonstrate a stronger negative relationship compared to those without a chronic pain condition. Pain catastrophizing is assessed using the Pain Catastrophizing Scale and cognitive functioning is evaluated using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), which includes measures of immediate memory, visuospatial/constructional skills, attention, and delayed memory. At this point, data analyses are still ongoing and results will be provided at the poster presentation.
