The Main Concept Analysis (MCA)
The Main Concept Analysis (MCA) assesses information transfer in verbal discourse production through a sequential picture description task involving four picture sets, focusing on the presence, accuracy, and efficiency of key concepts. Over the past twenty years, this method has been widely used to analyse discourse informativeness in both clinical and non-clinical populations. MCA has been fully or partially validated for use in multiple languages, including English, Cantonese-Chinese, Mandarin-Chinese, Spanish, Dutch, Japanese, and Korean. It provides a valuable addition to existing language assessment tools.

Cantonese Version of the Comprehensive Aphasia Test (Cant-CAT)
The Comprehensive Aphasia Test (CAT) is a test for use with people who have acquired aphasia, that can be completed over one or two assessment sessions. It is an extensive standardized and formal battery that consists of 34 subtests divided into three parts, including the Cognitive Screen, the Language Battery, and a concise Aphasia Impact Questionnaire (or the Disability Questionnaire in the former edition).
The Cantonese version of CAT (or Cant-CAT) was translated into Chinese and modified with careful control of the psycholinguistic variables specific to Cantonese.

Cantonese Aphasia Battery (CAB)
The CAB was designed by Professor Edwin Yiu, based on the English language Western Aphasia Battery. The test assesses the language function of adults with neurological disorders, such as those resulting from stroke, head injury or dementia. It has been widely used to assess Cantonese speakers with aphasia worldwide.

Hong Kong Version of the Oxford Cognitive Screen (HK-OCS)
The OCS is a stroke specific, rapidly administered, cognitive screening tool. The OCS provides clinicians with a visual, easy-to-interpret, cognitive profile of their clients, including clients with aphasia. The HK-OCS is a version specifically developed for Cantonese-speaking stroke survivors

Hong Kong Cantonese Version of the Birmingham Cognitive Screen for Stroke Survivors (HK-BCoS)
The BCoS is a neuropsychological test battery designed to assess impairment to a variety of cognitive domains, including language, in clients with brain injuries. By assessing clients across different domains, the BCoS can aid clinicians in designing rehabilitation programmes and evaluating therapy outcomes. The HK-BCoS was developed as a tool for work with Cantonese-speaking clients in Hong Kong and found to be a valid, reliable tool for stroke survivors.
