A cost-effective means of improving the statistical validity of an MMPI short form
Abstract:
Faschingbauer Abbreviated MMPI (FAM) scales were K-corrected using the FAM K scale or the standard K scale (N = 1,258 normals; 1,181 psychiatric inpatients). The latter increased the correlation between abbreviated and standard scales by amounts proportional to the degree of K-correction. Because using the entire K scale involves the addition of only 11 items to the FAM while it improves the statistical validity of 4 scales in addition to K, this was proposed as a cost-effective means of improving the FAM.

Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...
