Abstract

Background: The Comprehensive Aphasia Test (CAT; Swinburn, Porter, & Howard, 2005) was published in 2005, the first new aphasia battery in English for 20 years.

Aims: We aim to describe the motivations driving design decisions in the development of the CAT, summarise data on its properties (reliability and validity), and consider reasons why it might be a suitable assessment for clinical use.

Main Contribution: The test is designed to (1) screen for associated cognitive deficits, (2) assess language impairment in people with aphasia, (3) investigate the consequences of the aphasia on the individual's lifestyle and emotional well-being, and (4) monitor changes in the aphasia and its consequences over time. This lead article discusses the CAT's advantages over other aphasia batteries available.

Conclusions: We argue that the CAT is based on the best available current theoretical knowledge about the variables known to affect aphasia performance, and gives as much information as is possible from a relatively short standardised aphasia battery for designing therapy plans, while also giving therapists information to make a prognosis when people with aphasia are assessed in the first few months after onset.

Bilingual aphasia rehabilitation is of increasing interest since more than half the worldís population is bilingual (Paradis, 1998). Although naming deficits have been reported extensively in bilingual aphasic individuals, the results of treatment studies for naming in bilingual aphasia (Galvez & Hinckley, 2003; Hinckley, 2003; Kohnert, 2002) have been equivocal. With regards to crosslinguistic generalization, cueing hierarchy treatments have revealed no crosslinguistic generalization for pairs of words (Galvez & Hinckley, 2003; Hinckley, 2003), and lexical-semantic treatment has resulted in crosslinguistic generalization for cognates only (Kohnert, 2002).

The present experiment attempts to address two unanswered questions in bilingual aphasia rehabilitation (Fabbro, 2001). First, is it sufficient to rehabilitate only one language? Second, does rehabilitation in one language have beneficial effects in the untreated language? We combined existing treatment methodologies for naming with theoretical models of bilingual language processing to guide treatment efforts for patients with bilingual aphasia.
