What's new for semantic feature analysis?

Revisiting a classic therapy technique

Semantic Feature Analysis

Aphasia is frequently associated with semantic breakdown

Semantic feature analysis is a technique that underpins the general philosophy behind many treatments for semantic impairments

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

Semantic Feature Analysis 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

Semantic Feature Analysis: CAPS

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

The Evidence: Research Design

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.

The Evidence: Participants

No correlation between treatment efficacy and Type of aphasia Severity of aphasia Time post onset Aetiology

Representative of the group caseload

The Evidence : Intervention

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)

The Evidence: Measurement

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

The Evidence: Outcomes

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

Applying these results to clinical practice

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

Future Research

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
