Abstract
Background: While language-related tests including communication activities of daily living-second edition (CADL-2) test showed that alike were able to test language-related functional and communication skills, psychoneurolinguists and speech language pathologists/ Therapists (SLP/Ts)’s responses varied between accepting or rejecting the results of this test. Purpose: Previous studies suggest that results of CADL-2 do not differ with both gender aphasics suffering from different language impairments. Thus, the current study tested the validity and reliability of this test among Arab aphasics. Design: CADL-2 Pre-and-posttest was administered twice in three weeks to test the communication activities of daily living of 100 aphasic participants of both sexes. Settings: Al Khars hospital in Al Ahsa’a, Kingdom of Saudi Arabia (KSA). Participants: A total of 100 (50 men and 50 women) gender aphasic participants who suffer from different language deficits were enrolled in this experimental study. Procedures: Having the English version of CADL-2 translated into Arabic and standardized by three Arabic language experts, the first CADL-2 (Arabic version) test (pre-test) was administered to the participants under investigation in the first week and after two weeks (exactly at the end of the third week)., the second CADL-2 (posttest) was administered. Both tests were conducted in natural environment without any influence from testers or participants’ families. Interventions: Results including gender-specific differences were qualitatively and statistically analyzed and comparisons were made to illustrate these results. Main outcomes & Results: The analysis results of each aphasic participant show that no significant differences were observed in CADL-2 pre-and-posttest. The test could test what it was supposed to test. Moreover, the results of the participants’ pre-and-posttest are similar with mean of percentile in the pre-and-posttest surging 29.5% and 28.6% and Stanine scores surging 3.4% and 3.32% for males in comparison to the female aphasic participants who scored 28.16% and 28.78% in the percentile and 3.38% and 3.38% in the Stanine scores. Taken together, the results demonstrate that the level of aphasics’ communication activities is low. Such results prove that the test is also reliable. Conclusions & Implications: CADL-2 is considered to be a validated tool for the assessment of Arab aphasic patients of both sexes. These results also provide much needed quantitative data for the diagnosis of language impairments in Arab aphasic patients.

Conclusions & Implications: CADL-2 is considered to be a validated tool for the assessment of Arab aphasic patients of both sexes. These results provide much needed quantitative data for the diagnosis of language impairments in Arab aphasic patients
Increasing number of assessment tools, notably those relating to adults throughout the world have created an urgent need for intensive investigations and strategies that clinicians and speech language Pathologists/ Therapists (SLP/Ts) use to meet the highest standards and criteria of diagnosis
Research has shown that stacked-wave-V auditory brainstem response (ABR) requires a masking technique that may not be readily available to the clinician
Summary
CADL-2 is considered to be a validated tool for the assessment of Arab aphasic patients of both sexes.
