Assessment of Aphasia Across the International Classification of Functioning, Disability and Health Using an iPad-Based Application.

BACKGROUND: Access2Aphasia™ is an iPad™-based aphasia assessment application that enables real-time audiovisual communication between people with aphasia (PWA) and speech-language pathologists (SLPs), and the use of supported conversation techniques. This study aimed to establish the reliability of aphasia assessment across the International Classification of Functioning, Disability and Health (ICF) using Access2Aphasia, and compare it with face-to-face (FTF) assessment. Consumer perspectives of Access2Aphasia were also examined. MATERIALS AND METHODS: Thirty PWA were randomized into two conditions: online-led and FTF assessment. Participants in the online-led group were assessed remotely using Access2Aphasia™ in their own homes, while an FTF SLP scored silently simultaneously. Participants in the FTF group were assessed FTF using standard administration materials. Assessment included two subtests of the Psycholinguistic Assessment of Language Processing Activities (PALPA) and the Assessment of Living with Aphasia (ALA) to allow for outcomes to be captured across the ICF domains. Consumer perspectives on Access2Aphasia were obtained from both PWA and research SLPs in the online-led group. RESULTS: Kappa statistics indicated moderate to almost perfect agreement between online and FTF SLPs (k = 0.71-1.00). Intrarater and interrater reliability was excellent (ICC = 0.99-1.00) and equivalent for the online-led and FTF conditions. Both PWA and research SLPs in the online-led group reported being satisfied with the experience overall, with suggestions provided by research SLPs to improve Access2Aphasia. CONCLUSION: This study supports the provision of iPad-based aphasia assessments across the ICF in the online environment, with comparable reliability to FTF assessments. Future research is warranted to support the development of iPad-based aphasia assessment and treatment as an alternative mode of service delivery to PWA.

Validation of the Stroke and Aphasia Quality of Life Scale in a multicultural population.

PURPOSE: This study aimed to determine the reliability and validity of the Stroke and Aphasia Quality of Life Scale (SAQOL-39 g) and its Mandarin adaptation SAQOL-CSg in Singaporean stroke patients. METHOD: First-time stroke survivors were recruited at three months post-stroke and underwent a series of questionnaires in their dominant language (English/Mandarin). This included: SAQOL-39 g/CSg, National University Hospital System (NUHS) Aphasia Screening Test, Barthel Index, Modified Rankin Scale, Mini Mental State Examination, Frontal Assessment Battery, Center for Epidemiologic Studies Depression Scale and the Eurol-Qol Health Questionnaire (EQ-5D). The SAQOL-39 g/SAQOL-CSg was repeated within 1 week (± 6 days). RESULTS: Ninety-four participants (96.9%) were able to self-report and their results presented here. Both the SAQOL-39 g/SAQOL-CSg showed good internal consistency (α = 0.96/0.97), test-retest reliability (ICC= 0.99/0.98), convergent (rs  =0.64-0.81 and 0.66-0.88, respectively) and discriminant (rs = 0.35-0.53 and 0.48-0.62, respectively) validity. The correlation between the SAQOL-39 g and the EQ-5D Visual Analogue Scale was 0.27. Further inspection of the EQ-5DVAS scores revealed correlations in different directions for Malay versus Chinese participants. CONCLUSIONS: Both the SAQOL-39 g and SAQOL-CSg demonstrated good reliability and validity. Our results suggested some influence of ethnicity in self-rating of health status in relation to SAQOL-39 g scores. Further research is warranted to examine its use with stroke survivors with greater stroke severity and over time. Implications for Rehabilitation Validation of SAQOL in Singapore: Both the SAQOL-39g and the SAQOL-CSg may be used to measure the HRQoL of stroke survivors with and without aphasia in Singapore. Further investigation is required to examine use with stroke survivors with greater stroke severity and over time.

Speech pathology services for people with aphasia: what is the current practice in Singapore?

PURPOSE: This study reports on current provision of aphasia services by speech pathologists in Singapore. METHOD: A 44-item web-based survey was conducted looking into areas of service delivery, assessment, cultural and linguistic adaptations, clinical approaches, education of clients, recovery, goal setting and discharge as well as scope and challenges to practice. RESULTS: A total of 36 surveys were completed representing approximately 86% of the potential target population. The intensity of aphasia services provided was well below that recommended by the literature. Participants reported embracing approaches to aphasia rehabilitation that spanned across the ICF domains. Numerous challenges were reported in providing aphasia services. These included the lack of locally relevant resources for aphasia, lack of family support and patient motivation, manpower shortages as well as barriers such as transport and cost restricting access to services. CONCLUSIONS: This research reveals several findings with considerable implications for practice planning and future direction in aphasia rehabilitation. There is a need for the development of locally relevant aphasia resources to enable comprehensive provision of aphasia services. In addition, further investigation is required to tackle the resource challenges faced by the profession and improve community support for people with aphasia. Implications for Rehabilitation Speech pathology services for aphasia in Singapore This article has identified the challenges of providing aphasia services in the Singapore context. Further investigation is required to address the key issues to improve aphasia services in Singapore. This includes developing locally relevant resources, looking at means like telerehabilition to tackle resource challenges, and improving community support for people with aphasia.

The impact of dysarthria on everyday communication after traumatic brain injury: a pilot study.

PRIMARY OBJECTIVE: To compare the everyday communication of individuals with mild and moderate dysarthria and concomitant cognitive-communication impairments following traumatic brain injury (TBI). METHODS AND PROCEDURES: Five participants with mild dysarthria and five with moderate dysarthria following TBI were recorded during telephone service enquiries with bus timetable call centre operators. Transcripts were analysed using exchange structure analysis derived from systemic functional linguistics. Listener comfort ratings were collected using a novel equal appearing interval scale to measure how comfortable people would feel interacting with the participants. MAIN OUTCOMES AND RESULTS: Participants with moderate dysarthria were not necessarily penalized for having poorer intelligibility during bus timetable service encounters. While participants with moderate dysarthria were given poorer listener comfort ratings, this did not affect the way information was exchanged with bus timetable call centre operators. These findings were attributed to the powerful interactional role of TBI participants as customers, the amount of disability awareness training and experience held by call centre operators and the highly structured nature of bus timetable service enquiries. Listener comfort ratings could be predicted with moderate accuracy from intelligibility scores. CONCLUSIONS: Service encounters where individuals with TBI are placed in a powerful interactional role of customer may be functional generalization tasks for people with moderate dysartrhia. Training and education of service providers may also impact on the communicative effectiveness of individuals with TBI.
