1 Linda Jones, Julia Murphy and Claire Layfield (Group Co-Leaders) Lyndsey Nickels - Academic Member Presented by Claire Layfield What's new for semantic feature analysis? Revisiting a classic therapy technique

2  Aphasia is frequently associated with semantic breakdown  Semantic feature analysis is a technique that underpins the general philosophy behind many treatments for semantic impairments

4 GROUP ACTION PROPERTIES ASSOCIATION (Boyle, 2001; Boyle, 2004; Coelho, McHugh, & Boyle, 2004; Kiran, & Johnson,2008; Kiran, 2008; Rider, Wright, Marshall & Page, 2008)

5  Semantic feature analysis therapy is provided at word level BUT our treatment goals are discourse based  Clinical Question: For people with aphasia, in what circumstances does SFA improve  Naming of treated items  Naming of untreated items  Generalisation to spontaneous speech

6  Initial searching by the group found 23 articles  From these 16 were CAPPED  The others were excluded because  Treatment data was not available (e.g. expert commentary)  Treatment was not applicable (e.g. neuroimaging)  The participants had speech and language impairments in addition to aphasia

7  Research design  Single case experimental design  Case series  Low level of evidence on NHMRC evidence hierarchy.  BUT well designed single case and case series, can be more powerful in terms of clinical applicability.

8  No correlation between treatment efficacy and  Type of aphasia  Severity of aphasia  Time post onset  Aetiology  Representative of the group caseload

9  Variability noted in  Treatment schedules  Therapy duration  Individual vs group based  Variability noted in therapy administration  Cueing hierarchies, prompts, responses to errors  Added components of discourse (put word into phrase)

10  Measures included  confrontational naming (typically treated and untreated items)  Standardised measures  Generalisation measures typically discourse based (CIU, words and error production rates)  Participation measures: Social validity questionnaire

11  Treated items  increased and maintained  Untreated items  Similar trends but reduced in magnitude  Standardised assessments  Small improvements to overall scores  Generalisation  At best “modest” improvements in discourse based measurements maintained over time

12  Semantic feature analysis  Appears to be clinically feasible  Increases naming, reduces perseveration, and this transfers to conversation in the short term  What remains in question is  Is this technique more beneficial than other therapy techniques and  Is there a way of combining this technique with a second level of phrase/sentence level therapy which may generate and maintain functional communication improvements

13  Research investigating  Semantic feature analysis vs other techniques which is controlled for therapy dosage  Semantic feature analysis in group vs individual settings  Systematic investigation of enhancing maintenance and generalisation  Outcomes from acute and chronic phases of therapy  would all be helpful to determine the extent and nature of the therapy benefits reported in the literature to date
