Standardised adult assessments

Arabic Comprehensive Aphasia Test (ACAT) A standardised, evidence-based comprehensive cognitive and language battery for Arabic-speaking adults

The Arabic Comprehensive Aphasia Test (ACAT) is an assessment tool for aphasia in Arabic-speaking adults.

  • 60minutes to run with mild cases, but may take longer with moderate to severe cases
  • 2parts the ACAT includes a cognitive part and a language part
  • Adults designed to be used with adult Arabic speakers following a brain injury

Overview

The ACAT takes approximately 60 minutes to run with mild cases, but may take longer with moderate to severe cases. You can run the test in full or part of it depending on the aim of the assessment, and the severity of the case. It is recommended that the full test is administered on two sessions or more.

This tool responds to the lack of standardised aphasia assessments for the Arabic language. The aim of the ACAT is to provide the user with a comprehensive cognitive and language profile, and an in-depth understanding of the nature of language breakdown following aphasia. The ACAT includes a cognitive part and a language part.

The cognitive part tests include

  • hemianopia
  • semantic memory
  • verbal fluency
  • visual memory
  • object use
  • arithmetic processing

The language part includes

  • a comprehension battery
  • repetition battery
  • spoken production battery
  • reading battery
  • writing battery

The tests included, and the accompanying scoring system, account for Arabic-specific linguistic features and cultural norms.

Uses

This test is designed to be used with adult Arabic speakers following a brain injury to assess their language in-depth, and build comprehensive profile of their language abilities and related cognitive processes. It can be used to assess patients for the first time and for retesting a case regularly to identify progress patterns.

However, it is recommended that the Arabic Short Aphasia Test (ASAT) is used prior to the ACAT. While the ASAT is designed to screen for the presence of aphasia and provide an overview of the language breakdown, the ACAT is designed to assess every language aspect in detail accounting for psycholinguistic factors known to influence language processing:

  • word frequency
  • syllable and phoneme length
  • familiarity
  • imageability
  • age-of-acquisition
  • image agreement
  • visual complexity
  • name agreement
  • reaction time data
  • morphological complexity
  • syntactic complexity

This enables the tester to build an in-depth speech and language profile for the patient and develop a well-informed and long-term intervention plan. Controlling for such variables would help the speech and language therapist/pathologist to determine whether there is improvement in a particular subset of stimuli (e.g. words with high frequency). This is especially essential in investigating the effects of therapy on different aspects of language.

The choice between the Arabic Short Aphasia Test (ASAT) and the Arabic Comprehensive Aphasia Test (ACAT) heavily depends on the assessment goals

The trade-off lies in balancing the need for a quick screening tool against the desire for a more exhaustive evaluation, emphasizing the importance of selecting the battery that aligns with the specific assessment goals and constraints of the clinical context.

The ASAT, a short and quick battery, serves as a valuable screening tool, providing clinicians with a rapid means of identifying potential cases of aphasia. Its brevity allows for efficient use in time-sensitive situations, enabling quick decision-making in clinical settings. However, the concise nature of this battery may limit the depth of evaluation and may not capture the full spectrum of language deficits.

On the other hand, the ACAT, with its comprehensive stimuli matched for psycholinguistic factors, offers a thorough examination of language processing across modalities. This battery excels in providing a nuanced understanding of linguistic impairments.
