Preliminary reliability and validity data are reported on a new, brief measure of psychiatric symptomatology. The Symptom Assessment-45 Questionnaire (SA-45) is a 45-item, patient self-report symptom inventory derived from the original Symptom Checklist-90-R (SCL-90), using cluster analytic methods. The SA-45 consists of nine 5-item scales assessing each of the same symptom domains as its parent instrument with no item overlap across domains. The vast majority of the internal consistency reliabilities for the SA-45's nine scales were in the .70s and .80s across different age and patient status samples. As expected, both adolescent and adult patient samples generally differed significantly from nonpatient control samples, and patients at treatment follow-up differed significantly from patients at intake. Moreover, depressed patients with and without psychotic features differed significantly on three scales. A cluster analysis generally supported the nine-scale structure of the inventory, but it failed to consistently support the distinction between the Paranoid Ideation and Interpersonal Sensitivity scales. Limitations to the study are noted, but overall, the initial findings support the use of the SA-45 in clinical settings. Suggestions for needed future research are presented.
Background and Purpose-The purpose of the present study was to develop and rate performance measures for hospital-based acute ischemic stroke. Methods-A national multidisciplinary panel of 16 individuals (2 stroke specialists, 2 general neurologists, 2 internists, 2 neuroscience nurses, 2 stroke advocacy organization representatives, 1 stroke rehabilitationist, 1 family practitioner, 1 emergency room physician, 1 neuroradiologist, 1 managed care organization director, and 1 hospital association representative) from 10 medical societies or lay organizations assisted in the development of 44 potential stroke performance measures. We developed evidence summaries for each of the performance measures and graded the level of evidence associated with each measure. The panel received a summary of the literature pertaining to each measure and rated the measures by use of a modified Delphi approach for 6 dimensions of quality, including validity of evidence, feasibility, impact on outcomes, room for improvement, plausibility, and an overall rating (little reason to do, could do, should do, and must do). Results-Highly rated and agreed on performance measures for the overall rating include warfarin in atrial fibrillation, antithrombotics on hospital discharge, carotid imaging in appropriate patients, and use of stroke units. Additional measures notable for high agreement were heparins for deep-vein thrombosis prophylaxis and use of a stroke protocol.Panelists rated time-related thrombolytic measures such as head CT within 25 minutes highly on the room for improvement dimension but low on the overall dimension. Neurologists tended to rate measures lower than did nonneurologists (PϽ0.01) for all 9 measures pertaining to thrombolytic management. Conclusions-Highly rated and agreed on performance measures exist in all domains of hospital-based stroke care.
