Sensitivity and specificity

Sensitivity and Specificity The two most imperative measures of analytical tests accurateness are sensitivity and specificity. Sensitivity of a trial concerns its competence in recognizing people with the disorder in question; in this context it would refer to alcohol problems (Peters, et al., 2000). Specified differently, sensitivity reproduces the quantity of individuals with alcohol use disorders appropriately recognized by the test (Peters, et al., 2000). A sensitive test is one that delivers a minimum of false negatives (Peters, et al., 2000). For instance, individuals with alcohol problems who are not noticed by the screening procedures. In general, a measure with an elevated level of sensitivity is necessary, and idyllically…

of not providing all the possible details to a doctor. In contrast, when patients present all the information to physicians, it helps to provide the basis for which diagnostic tests are deemed necessary. Diagnostic tests are based on statistical science, and science is not absolute. The data from the tests is in the form of ratios and probabilities which are calculated with mathematical formulas. Diagnostic tests have the criteria of either sensitivity or specificity to screen for possible…

Physical findings and tests reduce indecision on whether the patient has the given condition or not (Bickley, 2013b), However sensitivity and specificity should be considered to avoid false diagnosis (Bickley, 2013b). Tests sensitivity refers to accurately being positive in individuals with the disease, while, specificity refers to individuals with out the disease shown as true negatives (Bickley, 2013b). Together, the higher the specificity and sensitivity the more accurate the test is, and the…

(Tariq, Tumosa, Chibnail, Perry 3rd, & Morley, 2006, p.900) Reported that it has a 30-point screening questionnaire that check for orientation, memory, attention, and executive functions. This screening test was compared to the popular Mini-Mental State Examination (MMSE), which only identify dementia. VAMC and SLU researchers examined the sensitivity and specificity of both cognitive screening test, and the results revealed acceptable receiver operator curves (ROCs) on both test. (Park, Goo, &…

barriers of time were the time it took to complete the tools and the patients’ level of cooperation. With these barriers in mind, they believe that even the 3D-CAM can be too long. An ultra brief screening tool has been created from the 3D-CAM to help recognize those with delirium in a timely manner with a two-step approach. If the two-step approach was positive, they would use the full 3D-CAM to help confirm the possible delirium. In the study by Fick et al. (2015), they discovered the two…

in the study. Each patient was assessed once a week over a time frame of four weeks, and if the patient had a fall incident or was discharged, the assessment was dismissed. In order to determine which scale was the best of three, sensitivity, specificity and positive and negative predictive values were assessed. The Morse Fall Scale yielded t he highest sensitivity, and the Bobath Memorial Hospital Fall Risk Assessment Scale yielded the lowest sensitivity. In this study, the Morse Fall Scale…

normal child bickering, because of this many were never resolved or healed causing them to grow over time. The difference between arguments with peers and real bullying is becoming harder and harder to define. This makes children afraid to speak their minds and have small disputes, and takes away a large portion of childhood development. The exposure to uncomfortable or disliked topics starts very early in one’s life and is vital to understanding the world. Without having a realistic view on the…

Ain’t Got the Time, Don’t Do the Crime Here at Stephen F. Austin State University, it is nearly a necessity to have the utmost pride and respect for the university, scholars, and faculty. However, there have been numerous accounts when the Community Assistants have failed to show any consideration towards anyone that goes near the front desks -- especially the students. These “assistants”, more commonly known as CA’s, obviously do not care about the students’ concerns, doing such things as…

Validity of screening tests in the medical field and the field of psychology is extremely important. These tests help decipher if an individual needs to proceed with further assessments (Gregory, 2011). Without validity of tests, one would not be able to accurately screen for mental health disorders or ailments within the body (Gregory, 2011). Medical screening tests coined the words “sensitivity” and “specificity” while testing for diseases (North Carolina School of Science and Mathematics…

results, the sensitivity of conventional US was 100%, specificity was 43% and accuracy was 73%. The PPV and NPV were 67%, and 100% respectively. These results agree with the study done by Balcik et al. (11), in which after examination of 135 mass lesions in 132 female patients, they found that the sensitivity of conventional US was 98.5 %, specificity was 56.2 % and accuracy was 77.7 %. The PPV and NPV were 71.1 %, and 97.2 % respectively. Also similar results was found in the study done by…
