Description of intervention(s) / exposure
Description of Protocol: NARNIA (Novel Approach to Real-life communication: Narrative Intervention in Aphasia) is a behavioural intervention that revolves around usual conversational speaking, but provides structure and feedback to the client using frameworks that are conceptually different to usual aphasia intervention. The NARNIA intervention protocol aims to increase awareness and use of language structures across a diverse range of everyday speaking situations, focusing simultaneously on word, sentence and discourse levels. Descriptions and preliminary results of the NARNIA intervention have been published in journals but the full protocol is not currently available. Adaptations for group delivery have been developed where usual clinical service delivery at a site is via group therapy. The protocol will be delivered under two conditions: (1) in 1-to-1 therapy (Study 1) and (2) in group therapy (Study 2). All participants will be assessed using the same assessment battery and undergo the same intervention. Given the two service delivery modes, the data from participants treated in individual sessions and those treated within a group will be analysed separately. While all participants will be analysed individually, performance of individuals in the two separate conditions will be compared in two groups. As numbers may be small, however, these will provide preliminary data only on the comparison of service models.This study is different to the original study in not collecting control data from participants receiving 'usual care'. It is designed specifically to collect data on individuals undergoing the NARNIA intervention, with each individual being analysed using a single case design to identify patterns of responsiveness to the intervention.
Aims: The overall study will examine treatment effectiveness in a clinical setting, individual variability, and feasibility of group delivery of this approach.Two separate studies are being conducted based on individual or group service delivery. Study 1 will involve providing NARNIA intervention individually to 10 people who would receive usual individualised out-patient services. Study 2 will involve adapting the NARNIA intervention and delivering this within a group setting to 10 people (3-4 per group), receiving usual group-based out-patient services.
Design: A single-case experimental design will be used, using each participant as their own control.
Schedule: The NARNIA intervention protocol will be delivered twice-weekly by a qualified speech pathologist, individually in Study 1 and in small groups (3-4 participants per group) in Study 2, over 10 weeks (20 sessions in total). Each sessions will run for one hour.
Adherence to the intervention protocol is being carried out in both studies. Therapy integrity will be monitored by the research team via video recording of a subset of sessions. Essential data on client attendance and performance will be collected on standardised data collection forms by treating speech pathologists to record treatment dose for individuals. One session per fortnight per participant will be video-recorded and coded against required essential elements of the NARNIA intervention protocol to establish fidelity. Any deviation from the prescribed therapy protocol will be discussed with the speech pathology team and noted for statistical analysis. Regular feedback will be provided to all therapists by the Research team in regular support meetings.

The same primary outcome measures will be collected on participants, irrespective of whether they undertake the intervention protocol in individual or group therapy.
(1) Change in frequency of macro structural language elements in samples of everyday discourse production, collected on the Curtin University Discourse Protocol (CUDP) (Whitworth et al, 2015). This is collected across 3 genres but is a composite score where the 3 genres (recounts, opinions, procedures) are collapsed into an everyday discourse composite score.

(2) Change in Informativeness of discourse production, as measured by Percentage Correct Information Units (%CIUs) (Nicholas & Brookshire (1993) in samples collected on the CUDP. This s a composite score of the data collected across the 3 everyday discourse genres, and reflects the relative frequency of relevant words to non-relevant production, and (2) 'Efficiency' which is measured by CIUs per minute which is the average frequency of CIUs per minute of information communicated. This measure will enable comparison with other studies.

(3) Change in the score on the Assessment of Living with Aphasia (ALA) (Simmons-Mackie et al, 2014). This tool encompasses a number of different domains (including social participation, communication activity, communication partners and is viewed as an overall measure of Quality of Life related to communication). It is purposefully weighted towards social relationships (i.e. communication environment), participation in life roles, and life satisfaction. These are reflected in an overall score.

Statistical methods / analysis
Each participant will be analysed as a single subject to investigate individual response to intervention. McNemar (two tailed) tests will be used where paired nominal data are present, e.g., picture naming, with Fisher Exact (two tailed) tests with Poisson distribution used on pairwise comparisons of unrelated data, e.g., discourse measures. A range of statistical analyses will be used to measure change in performance on other variables of interest in response to the novel intervention, e.g. social participation and life measures. A series of Geneneralized Linear Mixed Models will be used to determine the main and interactive effects of time (baseline, immediately post-intervention, and maintenance) on discourse performance measures (structural language measures, %CIUs and CIUs/min) and type of therapy delivery (individual, group). Qualitative data collected through the pre- and post-intervention semi-structured interviews will be transcribed verbatim and analysed using content thematic analysis.

Summary
Brief summary
A new approach to therapy for people with aphasia (language impairment after stroke) has been developed by our team which, when compared to usual car in a pilot trial, has provided highly promising evidence of greater gains in everyday speaking, participation in daily activities, and quality of life. The protocol, NARNIA (a Novel Approach to Real-life communication: Narrative Intervention in Aphasia), is a highly structured language therapy delivered using a natural interactive approach. As different service delivery models are in place within clinical settings, i.e. individual 1-to-1 therapy and group therapy, 10 people will receive individual therapy and 10 will receive group therapy. We aim to examine treatment effectiveness in a clinical setting, individual variability, and feasibility of group delivery of this approach.

No/undecided IPD sharing reason/comment
HREC approval has been granted to enable aggregated, non-identifiable data from the project to be provided to Principal Investigators of other studies, on request and where ethical approval is in place, to address research questions examining aphasia intervention. With increasing use of aggregated data by research teams, it is anticipated that access to data from this study may be requested to contribute to meta-analyses and analysis of combined data, facilitating further advances in this area. Information has been included in the Participant Information Sheets and Consent Forms to ensure participants are informed and understand that this may happen. No information will be identifiable to individual participants.
