This is the re-assessment of reliability and validity of Survey of Pain Attitudes-brief (SOPA-brief) version, with 183 chronic non-cancer pain patients. The SOPA-brief assesses the chronic pain beliefs related to emotion, control, solicitude, medical cure, harm, disability and medication. The analysis showed seven domains and 28 items. There were differences in the allocation of two items and after analyses they were excluded. Four domains had good Cronbach's alpha values (between 0.74 and 0.85) and three had moderate (between 0.58 and 0.65). The SOPA-brief version in Portuguese language is superior to its first version.
