Funnel plots, introduced by Light and Pillemer in 1984 [1] and discussed in detail by Matthias Egger and colleagues, [2] [3] are useful adjuncts to meta-analyses. A funnel plot is a scatterplot of treatment effect against a measure of study precision.
In 1997, Egger published a paper describing a method for detecting bias in meta-analyses by analyzing funnel plots. [4] This paper has been cited more than 38,600 times on Google Scholar as of May 2022. [5] In 2005, Egger published a study comparing 110 trials of homeopathy with 110 trials of conventional medicine in the Lancet.
Fluency is tested by asking the patient to say as many words as they can think of starting with a specified letter within one minute; and naming as many animals as they can think of in one minute. An example of this would be the tester asking the test taker to list every word they can think of that starts with the letter C.
Administration and interpretation of results should only be completed by a professional with the proper qualifications. The test creators advise that test users have completed a recognized graduate training program in psychology, supervised training and experience with personality scales, and possess an understanding of Millon's underlying theory.
A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli , and is associated with impulsivity .
[85] [86] In general, the test-retest reliabilities in the Korean sample were comparable to those in the American sample. For both culture samples, the median test-retest reliabilities were found to be higher for females than for males: 0.75 for Korean males and 0.78 for American males, whereas it was 0.85 for Korean females and 0.81 for ...
The most widely used method in the United States is based on the work of Exner. Administration of the test to a group of subjects, by means of projected images, has also occasionally been performed, but mainly for research rather than diagnostic purposes. [26] Test administration is not to be confused with test interpretation:
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
