The effectiveness of the MCMI-III Validity scale, Scale X, and the Clinical Personality Pattern scales to detect random responding is put to the test. The binomial expansion and Monte Carlo techniques were used. If the examiner is willing to interpret tests of questionable validity, then 50% of the random responders will not be detected. Scale X and the(More)
Criterion-referenced (Livingston) and norm-referenced (Gilmer-Feldt) techniques were used to measure the internal consistency reliability of Folstein's Mini-Mental State Examination (MMSE) on a large sample (N = 418) of elderly medical patients. Two administration and scoring variants of the MMSE Attention and Calculation section (Serial 7s only and WORLD(More)
The psychometric properties of the Hooper Vsual Organization Test (VOT) have not been well investigated Here the authors present internal consistency and interrater reliability coefficients, and an item analysis, using data from a sample (N = 281) of "cognitively impaired" and "cognitively intact" patients, and patients with undetermined cognitive status.(More)
Coefficient alpha and an item analysis were calculated for the 16-item Benton Visual Form Discrimination Test (VFDT) using a heterogeneous sample (N = 293) of mostly elderly medical patients who were suspected of having cognitive impairment. The total score reliability was .74. An item analysis found that 15 of the items were within established criteria for(More)
The Beck Depression Inventory II (BDI-II) has been suspected of overestimating the level of depression in individuals that endure chronic pain. Using a sample (N = 345) of male military veterans with chronic pain enrolled in an outpatient treatment program, a factor analysis on the BDI-II revealed a "Somatic Complaints" factor along with 2 other factors we(More)
Using the Kuder-Richardson formula 20 (KR-20) corrected for item difficulty, the internal consistency reliability of the Halstead Category Test (HCT) was calculated for a sample (N = 398) of normal patients and volunteers, diffusely brain-damaged patients, and undiagnosed patients sent for neuropsychological assessment. The HCT Total Score reliability(More)
Several studies have investigated random responding to the F, F Back, and VRIN scales. Only one study attempted to provide practical cutoff scores for these scales, but was unable to reach definitive cutoffs. This study uses the normal approximation to the binomial distribution and provides confidence interval bounds for random responding at the 95, 90, and(More)
Internal consistency reliabilities were calculated for the Tactual Performance Test blocks-per-minute scores for the Preferred Hand (n=298), Nonpreferred Hand (n=302), and Both Hands (n=314) trials, and Total Time. Reliabilities are reported for the total sample and three groups of normal, alcoholic, and undiagnosed patients sent for assessment. The(More)
