RESUMO
The International Classification of Impairment, Disabilities and Health by the World Health Organization had a profound influence on assessing and treating people with acquired brain injuries (ABI), which cause a movement from using impairment-based intervention to use therapies that focused on improving the participation and function of the individual's daily life. Although the first step of any therapy plan is to measure the damaged function of the related dimension, no available functional communication test for Persian-speaking people with ABI is available. Our purpose of this study was to provide a Functional Communication Test for Persian-speaking patients to measure the strengths and weakness of communication in dementia-free patients with ABI. In this cross-sectional study, the first version of the Persian Functional Communication Test (P-FUCT) was designed based on the structure of the most common functional communication tests such as ASHA-FACS and CADL. The content validity ratio (CVR) were determined. The final version of P-FUCT was administered on 30 dementia-free patients with ABI completed once by a clinician and once by the caregivers and the correlation between the scores was obtained. Concurrently, the P-WAB-1 was administered to assess the concurrent validity of the P-FUCT. The results indicated that P-FUCT has an acceptable level of internal consistency (alpha = 0.96), inter-rater 0.91 and intra-rater measurements 0.95 p < 0.05 with an adequate CVR of 0.71. The correlation between P-WAB-1 and P-FUCT scores completed by clinicians and the caregivers was r = 0/79 and r = 0/80. The P-FUCT is a valid and reliable assessment tool can be use for measuring the function communication ability of dementia-free patients with ABI.
RESUMO
INTRODUCTION: In this study, we reported the reliability and validity of Bedside version of Persian WAB (P-WAB-1) adapted from Western Aphasia Battery (WAB-R) (1,2). P-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. For the purposes of a quick clinical screening of aphasia in Persian, we adapted the bedside version of WAB-R to assess the performance of Persian aphasic patients. METHODS: The data we reported on adaptation, validity and reliability of P-WAB-1 are based on faithful translation and criterion validity ratio (CVR) taken from the expert panel and the performance of 60 consecutive brain damaged patients referred to different university clinics for rehabilitation and 30 healthy subjects as norms and 40 age-matched epileptic patients as the control group. RESULTS: Based on the results of this study, P-WAB-1 has internal consistency (a=0.71) and test-retest reliability (r=.65 P<0.001) and the subtests are sensitive enough to contribute to Aphasia Quotient (AQ) as a functional measure of severity of aphasia in Iranian brain damaged patients. Based on AQ results, our aphasic patients were classified into four distinct groups of severity. DISCUSSION: P-WAB-1 is the first clinical linguistic test to determine severity of aphasia based on an operational index and can be considered as a valid baseline for screening and diagnosis of aphasia among Persian speaking brain damaged patients. This study is the initial step on adaptation of different versions of WAB-R to measure the severity of aphasia using AQ, LQ and CQ as operational measures and to classify Persian speaking aphasic patients into different types.
