Vaegter HB, et al. - This study was performed to investigate the concurrent validity of brief psychological screening questions assessing anxiety, fear of movement, stress, pain catastrophization, and depression in chronic pain patients. Researchers, in addition, determined screening question cut-points at which the likely probability of having these psychological states was <10%. They realized that by using these screening tests and scoring thresholds, they could have correctly identified that between 38.5% and 60.5% of the sample were unlikely to have these psychological states (true negatives), with a false-negative rate between 3.4% and 5.3%. Hence clinicians would be able to determine the presence of other patient attributes in those patients requiring more thorough investigation via comprehensive validated questionnaires or structured clinical interviews.
