Complexity and Feedback During Script Training in Aphasia: A Feasibility Study.

ABSTRACT:

Objective

To explore the effect of complexity and feedback on script training outcomes in aphasia DESIGN: Randomized balanced single-blind 2 × 2 factorial design.

Setting

Freestanding urban rehabilitation hospital.

Participants

Adults with fluent and nonfluent aphasia (at least 6 months post onset).

Interventions

Experimental treatment was AphasiaScripts, a computer-based script training program. Scripts were 10-turns long and developed at different complexity levels to allow for comparison of high vs low complexity. The program was modified to contrast high vs low feedback conditions during sentence practice. Participants were instructed to practice three 30-minute sessions per day, 6 days per week for 3 weeks.

Main outcome measures

Gains achieved from baseline in accuracy and rate of production of trained and untrained script sentences at post treatment and at 3-, 6-, and 12-weeks after the end of treatment.

Results

Sixteen participants completed the intervention. On the trained script, gains were statistically significant for both accuracy and words per minute at post treatment and 3-, 6-, and 12-week maintenance. Gains on the untrained script were smaller than on the trained script; they were statistically significant only for accuracy at post treatment and 3-week maintenance. Complexity had an influence on accuracy at post-treatment (F₁=4.8391, P=.0501) and at maintenance (F₁=5.3391, P=.0413). Practicing scripts with high complexity increased accuracy by 11.33% at post treatment and by 9.90% at maintenance compared with scripts with low complexity. Participants with nonfluent aphasia made greater gains than those with fluent aphasia. There was no significant effect of feedback.

Conclusions

This study reinforces script training as a treatment option for aphasia. Results highlight the use of more complex scripts to better promote acquisition and maintenance of script production skills. There is a need for further investigation of these variables with larger samples and with other types of aphasia treatments.

Project description:Purpose This study sought to determine the initial feasibility and benefit of a novel intervention that combines speech-language treatment with counseling treatment for an individual with the nonfluent/agrammatic variant of primary progressive aphasia (PPA). Method Using a single-case experimental design, we evaluated the utility of modified script training paired with aphasia-modified cognitive behavioral therapy. The study employed a multiple baseline design across scripts for the primary linguistic outcome measure and a mixed methods approach for analyzing counseling outcomes. Psychosocial and communicative functioning scales were administered in conjunction with a phenomenological analysis of semi-structured interviews. Results The participant completed all study phases and participated in all treatment components. She met the criterion of 90% correct, intelligible scripted words on all trained scripts through 12 months post-treatment. Treatment outcomes were comparable to a comparison cohort that received script training without counseling (Henry et al., 2018). At post-treatment, the participant demonstrated stability or improvement on all measures of psychosocial and communicative functioning, with stability documented on seven out of 11 scales at follow-ups through 12 months post-treatment. A phenomenological analysis revealed pervasive themes of loss and resilience at both time points, and emerging themes of positive self-perception, sense of agency, and emotional attunement following treatment. Conclusions Results indicate that script training with aphasia-modified cognitive behavioral therapy is a feasible treatment for an individual with the nonfluent/agrammatic variant of PPA, with immediate and lasting benefits to speech-language production and psychosocial functioning. These findings are the first to support the integration of personal adjustment counseling techniques within a speech-language treatment paradigm for PPA.

Project description:To assess the feasibility and acceptability of training stroke service staff to provide supported communication for people with moderate-severe aphasia in the acute phase; assess the suitability of outcome measures; collect data to inform sample size and Health Economic evaluation in a definitive trial.Phase II cluster-controlled, observer-blinded feasibility study.In-patient stroke rehabilitation units in the UK matched for bed numbers and staffing were assigned to control and intervention conditions.70 stroke rehabilitation staff from all professional groups, excluding doctors, were recruited. 20 patients with moderate-severe aphasia were recruited.Supported communication for aphasia training, adapted to the stroke unit context versus usual care. Training was supplemented by a staff learning log, refresher sessions and provision of communication resources.Feasibility of recruitment and acceptability of the intervention and of measures required to assess outcomes and Health Economic evaluation in a definitive trial. Staff outcomes: Measure of Support in Conversation; patient outcomes: Stroke and Aphasia Quality of Life Scale; Communicative Access Measure for Stroke; Therapy Outcome Measures for aphasia; EQ-5D-3L was used to assess health outcomes.Feasibility of staff recruitment was demonstrated. Training in the intervention was carried out with 28 staff and was found to be acceptable in qualitative reports. 20 patients consented to take part, 6 withdrew. 18 underwent all measures at baseline; 16 at discharge; and 14 at 6-month follow-up. Of 175 patients screened 71% were deemed to be ineligible, either lacking capacity or too unwell to participate. Poor completion rates impacted on assessment of patient outcomes. We were able to collect sufficient data at baseline, discharge and follow-up for economic evaluation.The feasibility study informed components of the intervention and implementation in day-to-day practice. Modifications to the design are needed before a definitive cluster-randomised trial can be undertaken.ISRCTN37002304; Results.

Project description:ObjectivesTo examine a narrative multisource feedback (MSF) instrument concerning feasibility, quality of narrative comments, perceptions of users (face validity), consequential validity, discriminating capacity and number of assessors needed.DesignQualitative text analysis supplemented by quantitative descriptive analysis.SettingInternal Medicine Departments in Zealand, Denmark.Participants48 postgraduate trainees in internal medicine specialties, 1 clinical supervisor for each trainee and 376 feedback givers (respondents).InterventionThis study examines the use of an electronic, purely narrative MSF instrument. After the MSF process, the trainee and the supervisor answered a postquestionnaire concerning their perception of the process. The authors coded the comments in the MSF reports for valence (positive or negative), specificity, relation to behaviour and whether the comment suggested a strategy for improvement. Four of the authors independently classified the MSF reports as either 'no reasons for concern' or 'possibly some concern', thereby examining discriminating capacity. Through iterative readings, the authors furthermore tried to identify how many respondents were needed in order to get a reliable impression of a trainee.ResultsOut of all comments coded for valence (n=1935), 89% were positive and 11% negative. Out of all coded comments (n=4684), 3.8% were suggesting ways to improve. 92% of trainees and supervisors preferred a narrative MSF to a numerical MSF, and 82% of the trainees discovered performance in need of development, but only 53% had made a specific plan for development. Kappa coefficients for inter-rater correlations between four authors were 0.7-1. There was a significant association (p<0.001) between the number of negative comments and the qualitative judgement by the four authors. It was not possible to define a specific number of respondents needed.ConclusionsA purely narrative MSF contributes with educational value and experienced supervisors can discriminate between trainees' performances based on the MSF reports.

Project description:BackgroundThere is an extensive library of language tests, each with excellent psychometric properties; however, many of the tests available take considerable administration time, possibly bearing psychological strain on patients. The Short and Tailored Evaluation of Language Ability (STELA) is a simplified, tablet-based language ability assessment system developed to address this issue, with a reduced number of items and automated testing process.ObjectiveThe aim of this paper is to assess the administration time, internal consistency, and validity of the STELA.MethodsThe STELA consists of a tablet app, a microphone, and an input keypad for clinician's use. The system is designed to assess language ability with 52 questions grouped into 2 comprehension modalities (auditory comprehension and reading comprehension) and 3 expression modalities (naming and sentence formation, repetition, and reading aloud). Performance in each modality was scored as the correct answer rate (0-100), and overall performance expressed as the sum of modality scores (out of 500 points).ResultsThe time taken to complete the STELA was significantly less than the time for the WAB (mean 16.2, SD 9.4 vs mean 149.3, SD 64.1 minutes; P<.001). The STELA's total score was strongly correlated with the WAB Aphasia Quotient (r=0.93, P<.001), supporting the former's concurrent validity concerning the WAB, which is a gold-standard aphasia assessment. Strong correlations were also observed at the subscale level; STELA auditory comprehension versus WAB auditory comprehension (r=0.75, P<.001), STELA repetition versus WAB repetition (r=0.96, P<.001), STELA naming and sentence formation versus WAB naming and word finding (r=0.81, P<.001), and the sum of STELA reading comprehension or reading aloud versus WAB reading (r=0.82, P<.001). Cronbach α obtained for each modality was .862 for auditory comprehension, .872 for reading comprehension, .902 for naming and sentence formation, .787 for repetition, and .892 for reading aloud. Global Cronbach α was .961. The average of the values of item-total correlation to each subscale was 0.61 (SD 0.17).ConclusionsOur study confirmed significant time reduction in the assessment of language ability and provided evidence for good internal consistency and validity of the STELA tablet-based aphasia assessment system.

Project description:BackgroundHealthcare organizations are often committed to preventing suicide among their patients, but they can struggle to adequately train providers and implement strategies grounded in evidence-based suicide prevention practices. Virtual patient simulations (VPS) offer the opportunity for providers at healthcare organizations and educational institutions to learn suicide prevention strategies using a realistic and risk-free environment. The purpose of this study was to gather feedback from leaders in the healthcare field regarding the feasibility and acceptability of VPS for their organizations.MethodsParticipants (N=9) included administrators, managers, and educators from a variety of health care settings. They were invited to independently test the VPS and participate in a subsequent focus group to provide feedback. Participants were asked about VPS acceptability, satisfaction, potential fit within the intended context, feasibility of delivery, motivation to use, and likelihood of adoption. Responses were audio recorded and transcribed for coding and thematic analysis.ResultsThemes emerged regarding perceived benefits of the VPS, considerations related to cost, barriers to implementation, and suggestions for improvement. Participants reported VPS trainings were acceptable and feasible, filling an important gap in the field especially around suicide safety planning, particularly for newer clinicians and students in training. Participants felt that this type of virtual training was particularly feasible given the recent increase in need for online trainings. Suggested improvements included the need to normalize the trial-and-error nature of the VPS for trainees prior to the start of the training, and to consider shortening the duration of the simulation due to learners not being able to bill for time while training.ConclusionsVPS may help to fill an important training need in the field of suicide prevention. The training suite may be best suited for certain settings, such as educational institutions, and most useful for populations including students and new clinicians. VPS may be particularly feasible for organizations that already utilize remote options for work and training.
