Abstract:
Introduction: The Aphasia Check List (ACL) is a comprehensive, time-saving tool for language evaluation in aphasia, including a cognitive assessment part. This cross-sectional study aimed to translate ACL into Persian and analyze the psychometric features of the translated version. The original version of the ACL was translated and adapted from German; its psychometric features were then determined.
Methods: Twenty People With Aphasia (PWA) and 50 age- and education-matched, cognitively healthy controls participated in this research. Possible floor and ceiling effects, discriminant validity, test-retest reliability, and internal consistency of the test were analyzed in addition to the evaluation of internal correlations between the test parts (language & cognition).
Results: Regarding the performance of PWAs in the language section and the cognitive subtests assessing attention, memory, and reasoning, there were no floor and ceiling effects. Adequate discriminant validities for the language section of the test [i.e., total score: (Mann-Whitney U= 6.000, P<0.001); diagnostic subtests scores: (Mann-Whitney U= 3.000, P<0.001), and each subtest individually. Besides, the attention subtest of the cognition section (Mann-Whitney U= 16.500, P<0.001) was also observed. There was no difference between the control and patient groups in the subtests of memory (Mann-Whitney U= 497.500, P=0.973) and reasoning (Mann-Whitney U= 3.000, P= 308). The test-retest reliability was acceptable in all subtests (ICC agreement= 0.573-0.984). The ACL-P suggested appropriate internal consistency (Cronbach’s alpha coefficient= 0.761 for test & retest scores). There were also significant correlations between language and cognition in the control and patient groups.
Conclusion: The ACL-P test indicated sufficient reliability and validity for the evaluation of Persian-speaking PWAs and is suggested to be used in studies on this population.

● The ACL-P possesses a medium level of item difficulty for the study participants with aphasia, based on floor and ceiling analysis. Thus, items are not too difficult that no patient can accomplish the tasks nor too easy that all patients can complete them.
● The ACL-P can differentiate between normal controls and individuals with aphasia who participated in the study based on discriminant validity results.
● The language part of the ACL-P has an adequate internal consistency; however, the cognition part of the test has weak internal consistency because it consists of different cognitive domains.
● The test has adequate reliability in both language and cognition parts when administered at different times on the same subjects.
Plain Language Summary
In this study, an aphasia test called Aphasia Check List was translated from German into Persian and then administered on a sample of normal and people with aphasia to determine its psychometric properties. This test covers both language and cognition skills using different types of verbal and non-verbal stimuli at different levels of difficulty in a fast and convenient way. The comprehensiveness of this test and its convenient scoring system led the researchers to conduct this study. The main result of the study was that the translated version of the test, like its original version, has adequate discriminant validity, test-retest reliability, and internal consistency.
