Summary
This study assessed the reliability of the Tactual Performance Test across different hand conditions and participant groups. Results show varying reliability coefficients, indicating the test
Area of Science:
- Neuropsychology
- Psychometrics
Background:
- The Tactual Performance Test (TPT) is a neuropsychological assessment tool.
- Evaluating the internal consistency reliability of the TPT is crucial for its valid application.
Purpose of the Study:
- To determine the internal consistency reliability of the Tactual Performance Test (TPT).
- To examine reliability across different TPT conditions: Preferred Hand, Nonpreferred Hand, Both Hands, and Total Time.
- To analyze reliability in diverse participant groups: healthy individuals, patients undergoing assessment, and individuals with alcoholism.
Main Methods:
- Internal consistency reliability was calculated using Cronbach's alpha.
- Analyses were performed on data from 300 (Preferred Hand), 302 (Nonpreferred Hand), and 314 (Both Hands) participants.
- Reliability coefficients were reported for the total sample and stratified subgroups.
Main Results:
- Reliability coefficients for the TPT trials ranged from .59 to .90.
- Specific reliability values varied across the Preferred Hand, Nonpreferred Hand, Both Hands, and Total Time measures.
- Reliability differed between the normal, undiagnosed patient, and alcoholic participant groups.
Conclusions:
- The Tactual Performance Test demonstrates acceptable to good internal consistency reliability.
- Reliability findings suggest the TPT is a dependable measure for assessing tactile performance in various clinical and research contexts.
- The TPT's reliability is influenced by hand condition and participant group characteristics.
