Area of Science:

  • Neuropsychology
  • Psychometrics

Background:

  • The Tactual Performance Test (TPT) is a key component of neuropsychological assessment.
  • Understanding the reliability of TPT subtests is crucial for accurate diagnosis.

Purpose of the Study:

  • To calculate the internal consistency reliabilities of the Tactual Performance Test for preferred hand, nonpreferred hand, and both hands trials.
  • To examine these reliabilities across a total sample and distinct subgroups.

Main Methods:

  • Internal consistency reliabilities were computed using the Gilmer-Feldt coefficient.
  • Data were analyzed for the total sample (N=715) and three subgroups: normal volunteers (n=118), inpatient alcoholics (n=95), and undiagnosed patients (n=103).

Main Results:

Related Experiment Videos

  • Reliabilities for TPT trials (preferred, nonpreferred, both hands) and total time ranged from .5584 to .8953.
  • Specific reliability coefficients varied across the different hand conditions and participant groups.

    • Conclusions:

    • The Tactual Performance Test demonstrates acceptable to good internal consistency across various conditions and populations.
    • These findings support the TPT's utility in neuropsychological assessments, though variations highlight the importance of considering specific subtest and group characteristics.
