| Summary: | Background: The Thai Adaptation of Naming Test (TANT) is useful for assessing naming ability among Thais with naming deficits. However, the TANT was developed in 2004, meaning some words have become less common. Consequently, the TANT was revised for modernity and suitability for the current Thai cultural context and to measure the psychological properties. Objectives: To assess the validity and reliability of the Thai Adaptation of Naming Test-Revised (TANT-Revised). Materials and methods: The TANT was revised by adjusting certain items for suitability to the current Thai cultural context, consisting of 2 parts: Pictures of words and semantic cues. Subsequently, the TANT-Revised was assessed for content validity index (CVI), content validity for the item (I-CVI), and content validity Index for scale (S-CVI) test by five expert speech-language pathologists (SLPs). Afterward, the TANT-Revised was examined for test-retest reliability by intraclass correlation coefficient (ICC) in an aphasia group and a normal group, with 13 people per group. Results: The results of testing for the validity of TANT-Revised by expert SLPs revealed that the validity for pictures (CVI = 0.96, S-CVI = 0.99, and I-CVI = 1) and semantic cues (CVI = 0.95, S-CVI = 0.99, and I-CVI = 1) have high reliability in the normal group at 0.79 and the aphasia group at 0.96. Conclusion: This study assessed the psychological properties of the TANT-Revised instrument used to test naming ability. The validity of the revision test was high, and the TANT-Revised was deemed acceptable by experts. In addition, the test-retest reliability of TANT-Revised was high in both the normal and aphasia groups, implying the TANT-Revised is an efficient instrument for confrontation naming ability. However, this study was a preliminary test revision, and insufficient norm data and factors are affecting the test score. |
