pathologies by providing a new form of objective measurement. As of yet, the concurrent validity of the aforementioned BSS in relation to conventional PROMs has not been well established. 20 The purpose of this study was to assess the concurrent validity of the 5R-STS BSS in patients with lumbar degenerative diseases by using data from two prospective studies. Methods Overview We used data from two prospective cohort studies, conducted between October 2017 and June 2018, for which consecutive patients scheduled for lumbar surgery were seen at a Dutch specialized outpatient

adequate measure of health status in patients with ASD, and minimal clinically important differences (MCIDs) (the smallest change in an outcome that would prompt a change in treatment) have not been reported. Therefore, we investigated the concurrent validity, discriminant ability, and responsiveness of PROMIS domains in ASD. We also estimated PROMIS MCIDs for this population. We hypothesized that legacy PROs would be correlated moderately or strongly with PROMIS, that PROMIS would be able to discriminate between levels of disease severity in ASD, and that PROMIS

this study are: 1) determine concurrent validity of human cadaver and human placenta brain aneurysm simulators; and 2) determine predictive validity by evaluating senior neurosurgical resident first-time performance in unruptured middle cerebral artery (MCA) aneurysm surgery after simulation training. Methods After approval by the local ethics committee, data were collected between April 2014 and May 2016. Human placentas were obtained and prepared as previously described, 17 in the microsurgical laboratory of the Federal University of Minas Gerais (UFMG), Belo

, the patients were asked to recall the words learned 30 minutes earlier. Mean performances on this test of delayed recall fell into the same patterns for the three subgroups ( Fig. 3 ). Fig. 3. Verbal learning data, based on selective reminding delayed free recall in 59 patients. Mean value of control group for delayed free recall = 9.85. For a definition of subtypes, see text. The concurrent validity for the subclassification derived from the Selective Reminding Test was tested against prose recall with the Wechsler Short Stories test, another memory

conducted using maximum likelihood estimation. Variance accounted for and factor loadings presented are from the varimax rotated model. Internal consistency of the ASK Nasal-12 was determined using the Cronbach α. 9 Discriminant validity was evaluated at the item level and at the subscale level. Paired sample t-tests were used to calculate discriminant validity of our measure from pre- to postsurgery to examine the discrimination of each item. Effect sizes were obtained using a standardized response mean from t-tests. Concurrent validity was measured using the Spearman

the average ADL score among all ADLs performed. To assess concurrent validity of the questionnaire in relation to multiple measures (that is, does the questionnaire measure what it is intended to measure), Spearman correlation coefficients were calculated between individual ADL scores from the questionnaire and pain and distress items from the first section of the questionnaire (internal source), as well as with scores on the 10 dimensions of the ODI (external source). In addition, average scores among all ADLs were correlated with average scores among all 10
