Internal consistency and validity of the Italian version of the Jebsen-Taylor hand function test (JTHFT-IT) in people with tetraplegia.

STUDY DESIGN: Psychometric study. OBJECTIVES: This study aimed to evaluate the internal consistency and validity of the Italian version of the Jebsen-Taylor hand function test (JTHFT-IT) in people with tetraplegia. SETTING: Italian spinal units. METHODS: Psychometric properties of the JTHFT-IT were assessed following international guidelines. The internal consistency was examined using Cronbach's alpha coefficient. Pearson's correlation coefficient was calculated for the concurrent validity of JTHFT-IT with a dynamometer, while the construct validity was calculated in comparison to that of the Van Lieshout test short version in Italian (VLT-SV-IT). RESULTS: The test was administered to 48 right-hand dominant people with tetraplegia. Cronbach's alpha calculation resulted in a value of 0.96 for the right hand and 0.94 for the left hand. In terms of the validity of the scale, the Pearson's correlation, as measured in relation to the VLT-SV-IT and dynamometer, showed statistically significant results (range for the correlation coefficient of between -0.96 and -0.12, p < 0.05). CONCLUSIONS: The findings of this study support the internal consistency and validity of the JTHFT-IT and its use among a population with cervical SCI as a measure of hand functionality.

Internal consistency and validity of the Jebsen-Taylor hand function test in an Italian population with hemiparesis.

PURPOSE: The aim of this study was to evaluate the internal consistency and validity of the Italian version of the Jebsen- Taylor Hand Function Test (JTHFT-IT) in Italian post-stroke adults with chronic hemiplegia or hemiparesis. METHODS: The test's internal consistency and validity were assessed by following international guidelines. Its internal consistency was examined using Cronbach's alpha (α) coefficient. Pearson's correlation coefficient was calculated for concurrent validity in comparison with a dynamometer instrument, whereas for construct validity, it was calculated in comparison with the mean execution time of the Wolf Motor Function Test time subscale (WMFT-IT-TIME). RESULTS: The test was administrated to 48 people with chronic stroke. Cronbach's alpha reported a value of 0.96 for the dominant hand and 0.92 for the non-dominant hand. To define the validity of the scale, Pearson's correlation as measured using the WMFT-IT-TIME, and the dynamometer showed statistically significant results. CONCLUSIONS: The present study supports the use of the JTHFT-IT as a measure of hand functionality in post-stroke adults with chronic hemiplegia or hemiparesis. It is an important tool for Italian professionals, and it can be useful both in clinical practice to evaluate improvement after rehabilitation treatments and for research in hand rehabilitation.

Italian Version of the Jebsen-Taylor Hand Function Test for the Assessment of Hand Disorders: A Cross-Sectional Study.

IMPORTANCE: Having a test to evaluate hand function is fundamental to occupational therapy practice. OBJECTIVE: To assess the psychometric properties of the Italian version of the Jebsen-Taylor Hand Function Test (JTHFT). DESIGN: Cross-sectional study. SETTING: Three health care institutions in Rome, Italy. PARTICIPANTS: 136 people with injuries, burns, or neurological diseases of the hand. INTERVENTION: No intervention was provided. OUTCOMES AND MEASURES: We administered the JTHFT, an assessment of fine motor skills during performance of activities of daily living, and compared results with dynamometer readings. RESULTS: The mean ± standard deviation total time required to perform all subtests was 89.47 ± 67.98 s for the dominant hand (DH) and 167.11 ± 257.58 s for the nondominant hand (NDH). Reliability procedures were applied to data from 51 participants; mean intrarater intraclass correlation coefficient (ICC) was .814 for the DH and .981 for the NDH, and mean interrater ICC was .818 for the DH and .821 for the NDH. Pearson's correlation coefficients were significant. CONCLUSION AND RELEVANCE: Results support the use of the Italian version of the JTHFT as a measure of functional dexterity in people with upper limb disorders. WHAT THIS ARTICLE ADDS: The JTHFT is a valid and reliable assessment tool for nonspecific hand diseases. Italian health professionals can now use the JTHFT with more confidence.

Cross-Cultural Adaptation and Validation of the Jebsen-Taylor Hand Function Test in an Italian Population.

Objective. This paper describes the Italian translation and adaptation to the Italian culture of the original version of the Jebsen-Taylor hand function test and conveys the procedure for testing its validity and reliability. Design. The cultural adaptation process and validation were based on data from a group of people with no clinical evidence of disease or impairment of the upper limbs. The process required a forward and reverse translation in its original language. The scale obtained was reviewed by 8 experts in the field of psychometrics dealing with statistical methods that are useful for the behavioral and social sciences. The Italian adapted version of the JTHFT was then produced and validated. Participants. The test was submitted to 320 people with no clinical evidence of disease in order to test its acceptability and consistency. Results. The total time required to perform each subtest was 80.16 ± 43.13 seconds for the nondominant hand (NDH) and 49.97 ± 27.28 seconds for the dominant hand (DH). The internal consistency (assessed with Pearson's r) and the reliability or the construct validity (assessed with Cronbach's alpha) are significative. Conclusions. This is the first study reporting the result of the translation, cultural adaptation, and validation protocols of the JTHFT in Italian. It provides a new tool for Italian professionals to measure the functionality of the hand in participants with various upper limb pathologies.
