The higher the correlation between scores at two time points, more stable the measure is. Based on 129 participants, the test-retest reliability of the MCMI-IV personality and clinical syndrome scales ranged from 0.73 (Delusional) to 0.93 (Histrionic) with a most values above 0.80. [1]
[10] After analysis of test-retest reliability, convergent validity, and divergent validity, the CD-RISC2 demonstrated "significant correlation" with both the CD-RISC as a whole and with the individual items of the CD-RISC. The authors argue that since the CD-RISC2 sufficiently represents the original measure, the 2-item CD-RISC2 can be ...
According to the Benton Test manual, test-retest reliability of the Benton Test is 0.85, and alternate form reliabilities range from 0.79 to 0.84. Correlation between immediate and delayed memory recall (Administration type A and D, respectively) ranges from 0.40 to 0.83, depending on the combinations of forms used.
The Wilcoxon Signed Rank Test assesses practice effects and Spearman's rho (p) correlation coefficient is conducted to assess test-retest reliability. Primary learning, recall and recognition measures are recorded as well as the more detailed process measures such as errors , contrast scores, and ratio.
The Minnesota Multiphasic Personality Inventory (MMPI) is a standardized psychometric test of adult personality and psychopathology. [1] A version for adolescents also exists, the MMPI-A, and was first published in 1992. [2]
If the correlation between separate administrations of the test is high (e.g. 0.7 or higher as in this Cronbach's alpha-internal consistency-table [6]), then it has good test–retest reliability. The repeatability coefficient is a precision measure which represents the value below which the absolute difference between two repeated test results ...
The test-retest reliability for over 6 years, as reported in the NEO PI-R manual, was the following: N = .83, E = .82, O = .83, A = .63, C = .79. Costa and McCrae pointed out that these findings not only demonstrate good reliability of the domain scores, but also their stability (among individuals over the age of 30).
The correlation between scores on the two alternate forms is used to estimate the reliability of the test. This method provides a partial solution to many of the problems inherent in the test-retest reliability method. For example, since the two forms of the test are different, carryover effect is less of a problem. Reactivity effects are also ...
