Verbbenämning hos vuxna med afasi : Bedömt med Action Naming Test

The ability to name verbs and nouns can differ in healthy adults (Strauss Hough, 2007) and in people with aphasia (Matzig, Druks, Masterson & Vigliocco, 2009). In individuals with aphasia, differences in ability to name nouns and verbs have been related to location of brain damage (Damasio & Tranel, 1993). Confrontation naming tests are frequently used in aphasia assessments to evaluate the ability to retrieve words (Herbert, Hickin, Howard, Osborne & Best, 2008).Action Naming Test (ANT) is a verb naming test that has been standardized in Swedish (Lindahl & Oskarsson, 2011; Stenberg & Wik, 2013), but no studies have been done on verb naming with ANT in Swedish individuals with aphasia, which is the aim of the present study. Some of the words in the Swedish standardization were problematic and consequently a re-analysis of the data was conducted by Stenberg and Wik (2013). The results of the ANT in the present study were compared with collected standardized data before and after the re-analysis. To investigate whether there were differences in the ability to name verbs and nouns, participants were also assessed with the Boston Naming Test (BNT). Participants were also asked to answer the health survey Short Form-36 (SF‑36), to investigate possible links between health and verb naming ability. The study enrolled 19 subjects (41–83 years, median age 68 years) with chronic aphasia and expressive difficulties.Participants performed significantly better in verb naming (ANT) than noun naming (BNT), both before (p=.007) and after (p<.001) the problematic words were excluded. The sample performed below norm levels on ANT, both before and after the exclusion, but the majority achieved a higher test result after the re-analysis. No significant differences were found in verb naming ability related to sex, age, educational level or location of brain damage. ANT can be used to assess naming ability in people with aphasia. However, when compared with standardized data, values ​​developed after the re-analysis should be used since the participants of this study performed significantly better after exclusion. The participants showed a significantly better performance on ANT than BNT, which supports the view that verb naming tests are of value.
