Tactual performance test trials: psychometric properties of the blocks-per-minute scores

Tactual performance test trials: internal consistency reliability using the Gilmer-Feldt coefficient

Internal consistency reliabilities using the Gilmer-Feldt coefficient were calculated for the Tactual Performance Test for the Preferred Hand (n=298), Nonpreferred Hand (n = 302), and Both Hands (n = 314) trials, and total time. Reliabilities were reported for the total sample and three groups: 118 normal volunteers, 95 inpatient alcoholics, and 103 undiagnosed patients sent for neuropsychological assessment. The reliabilities ranged from .5584 to .8953.

Difference score reliability for tactual performance test trials

In further analysis of published data difference score reliabilities are presented for the difference between raw score and blocks-per-minute trial scores on the Tactual Performance Test.
