Bringing Gratitude to Aphasia Intervention: A Scoping Review of Gratitude Interventions for Adults with Chronic Health Conditions.

Aphasia negatively impacts mental health, disrupting social connections and meaningful life activities. Gratitude interventions for healthy adults positively impact well-being, physical health, and mental health. A systematic review of gratitude interventions for people living with chronic health conditions was conducted to identify current practices and existing gaps and to map the literature for incorporating gratitude interventions into aphasia rehabilitation. A scoping review of the literature published prior to March 2023 was conducted using CINAHL, Google Scholar, PubMed, and ERIC to identify gratitude interventions for adults with chronic health conditions. The search identified 414 studies. Five met the inclusion criteria. Interventions targeting chronic health conditions included alcohol use disorder, chronic heart failure, cancer, and asthma. No empirical studies were identified that used gratitude interventions with people who have aphasia or have had a stroke. Four studies used journaling as the intervention and one used gratitude letters. All interventions used written or verbal expressions of gratitude. Gratitude interventions have been used in limited ways with chronic health conditions. As gratitude interventions are language-based and rely on writing, people with aphasia may need modifications to support accessibility to these interventions which can positively impact mental health and well-being.

Validity and reliability of the Pain Assessment in Impaired Cognition 15 (PAIC15) observation scale in persons with aphasia.

BACKGROUND: The use of self-report pain scales in persons with aphasia can be challenging due to communication and cognitive problems, while for assessing pain self-report pain is considered the gold standard (Harrison RA, Field TS. Post stroke pain: identification, assessment, and therapy. Cerebrovasc Dis. 2015;39(3-4):190-201.). An observational scale may be used as an alternative. This study examines the validity and reliability of the observational Pain Assessment in Impaired Cognition (PAIC15) scale in persons with aphasia. METHODS: Persons with aphasia were observed during rest and transfer by two observers using the PAIC15. The PAIC15 comprises 15 items covering the three domains of facial expressions, body movements, and vocalizations. When able, the participant completed four self-report pain scales after each observation. The observations were repeated within one week. For criterion validity, correlations between the PAIC15 and self-report pain scales were calculated and for construct validity, three hypotheses were tested. Reliability was determined by assessing internal consistency, and intra- and interobserver agreement. RESULTS: PAIC15 observations were obtained for 71 persons (mean age 75.5 years) with aphasia. Fair positive correlations (rest: 0.35-0.50; transfer: 0.38-0.43) were reported between PAIC15 and almost all self-report pain scales. Results show that significantly more pain was observed in persons with aphasia during transfer than during rest. No differences were found for observed pain between persons with aphasia who use pain medication and those without, or persons who have joint diseases compared to those without. Results showed acceptable internal consistency. Intra- and interobserver agreement was high for most PAIC15 items, particularly for the domains body movements and vocalizations during rest and transfer. CONCLUSIONS: Recognition of pain in persons aphasia using the PAIC15 showed mixed yet promising results.

Speaking Up and Being Heard: The Importance of Functional Communication and Discourse Principles in Aphasia Intervention.

This article acknowledges Audrey Holland's influence on aphasiology as it specifically relates to the emergence of a strengths-based perspective on the everyday communication of people with aphasia. We explore a historical perspective, as well as current ways in which everyday communicative events are approached in both clinical and research practice. The term "functional communication" is synonymous with Audrey's work, with linguistically-based discourse analysis and therapy both viewed as natural companions and extensions of the concept within aphasiology. Audrey's focus on the interactional side of communication and psychosocial impacts of aphasia, as well as her expertise in analysis and measurement, contributed to the coalescing of impairment-based and social communication approaches, encompassing a true sense of humanity and connectedness. Her application of these in international contexts was also noteworthy. In this article, we hope to capture principles of aphasia management that underpin current clinical practice, and also move beyond the traditional clinic context to consider aphasia groups that have had such a key role in promoting successful social communication by and with people with aphasia. We suggest future directions to further promote the principles advocated by Audrey Holland in assisting people with aphasia to move forward with confidence with their conversation partners, friends, and communities.

'A Meaningful Difference, but Not Ultimately the Difference I Would Want': A Mixed-Methods Approach to Explore and Benchmark Clinically Meaningful Changes in Aphasia Recovery.

INTRODUCTION: Outcome measurement instruments (OMIs) are used to gauge the effects of treatment. In post-stroke aphasia rehabilitation, benchmarks for meaningful change are needed to support the interpretation of patient outcomes. This study is part of a research programme to establish minimal important change (MIC) values (the smallest change above which patients perceive themselves as importantly changed) for core OMIs. As a first step in this process, the views of people with aphasia and clinicians were explored, and consensus was sought on a threshold for clinically meaningful change. METHODS: Sequential mixed-methods design was employed. Participants included people with post-stroke aphasia and speech pathologists. People with aphasia were purposively sampled based on time post-stroke, age and gender, whereas speech pathologists were sampled according to their work setting (hospital or community). Each participant attended a focus group followed by a consensus workshop with a survey component. Within the focus groups, experiences and methods for measuring meaningful change during aphasia recovery were explored. Qualitative data were transcribed and analysed using reflexive thematic analysis. In the consensus workshop, participants voted on thresholds for meaningful change in core outcome constructs of language, communication, emotional well-being and quality of life, using a six-point rating scale (much worse, slightly worse, no change, slightly improved, much improved and completely recovered). Consensus was defined a priori as 70% agreement. Voting results were reported using descriptive statistics. RESULTS: Five people with aphasia (n = 4, > 6 months after stroke; n = 5, < 65 years; n = 3, males) and eight speech pathologists (n = 4, hospital setting; n = 4, community setting) participated in one of four focus groups (duration: 92-112 min). Four themes were identified describing meaningful change as follows: (1) different for every single person; (2) small continuous improvements; (3) measured by progress towards personally relevant goals; and (4) influenced by personal factors. 'Slightly improved' was agreed as the threshold of MIC on the anchor-rating scale (75%-92%) within 6 months of stroke, whereas after 6 months there was a trend towards supporting 'much improved' (36%-66%). CONCLUSION: Our mixed-methods research with people with aphasia and speech pathologists provides novel evidence to inform the definition of MIC in aphasia rehabilitation. Future research will aim to establish MIC values for core OMIs. PATIENT OR PUBLIC CONTRIBUTION: This work is the result of engagement between people with lived experience of post-stroke aphasia, including people with aphasia, family members, clinicians and researchers. Engagement across the research cycle was sought to ensure that the research tasks were acceptable and easily understood by participants and that the outcomes of the study were relevant to the aphasia community. This engagement included the co-development of a plain English summary of the results. Advisors were remunerated in accordance with Health Consumers Queensland guidelines. Interview guides for clinicians were piloted by speech pathologists working in aphasia rehabilitation.

Determinants of Multilevel Discourse Outcomes in Anomia Treatment for Aphasia.

PURPOSE: Individuals with aphasia identify discourse-level communication (i.e., language in use) as a high priority for treatment. The central premise of most aphasia treatments is that restoring language at the phoneme, word, and/or sentence level will generalize to discourse. However, treatment-related changes in discourse-level communication are modest, are poorly understood, and vary greatly among individuals with aphasia. In response, this study consisted of a multilevel discourse analysis of archival, monologic discourse outcomes across two high-intensity Semantic Feature Analysis (SFA) clinical trials. Aim 1 evaluated changes in theoretically motivated discourse outcomes representing lexical-semantic processing, lexical diversity, grammatical complexity, and discourse informativeness. Aim 2 explored the potential moderating role of nonlanguage cognitive factors (semantic memory, divided attention, and executive function) on discourse outcomes. METHOD: This study was a retrospective analysis of archival monologic discourse outcomes after intensive SFA for n = 60 (Aim 1) and a subset n = 44 (Aim 2). Outcome measures included lexical-semantic processing (% semantic errors), lexical diversity (moving average type-token ratio), grammatical complexity (mean utterance length), and discourse informativeness (% correct information units). Bayesian generalized mixed-effects models were used to examine changes across four study time points: enrollment, entry, exit, and 1-month follow-up. RESULTS: The present study found no evidence for meaningful or statistically reliable improvements in monologue discourse performance after SFA when measured using standard, general-topic discourse stimuli. There was weak and inconsistent evidence that nonlanguage cognitive factors may play a role in moderating treatment response. CONCLUSIONS: These findings indicate a clear need to pair theoretically informed treatments designed to facilitate generalization to discourse with intentional measurement paradigms designed to capture it. Furthermore, there is a clear need to examine how established treatments, restorative or compensatory, can better facilitate generalization to discourse-level communication. These priorities are critical for meaningfully improving everyday communication and reducing the profound communication and psychosocial consequences of aphasia.

Vigilant Attention During Cognitive and Language Processing in Aphasia.

PURPOSE: Persons with aphasia (PWA) experience differences in attention after stroke, potentially impacting cognitive/language performance. This secondary analysis investigated physiologically measured vigilant attention during linguistic and nonlinguistic processing in PWA and control participants. METHOD: To evaluate performance and attention in a language task, seven PWA read sentences aloud (linguistic task) and were compared to a previous data set of 10 controls and 10 PWA. To evaluate performance and attention in a language-independent task, 11 controls and nine PWA completed the Bivalent Shape Task (nonlinguistic task). Continuous electroencephalogram (EEG) data were collected during each session. A previously validated EEG algorithm classified vigilant-attention state for each experiment trial into high, moderate, distracted, or no attention. Dependent measures were task accuracy and amount of time spent in each attention state (measured by the number of trials). RESULTS: PWA produced significantly more errors than controls on the linguistic task, but groups performed similarly on the nonlinguistic task. During the linguistic task, controls spent significantly more time than PWA in a moderate-attention state, but no statistically significant differences were found between groups for other attention states. For the nonlinguistic task, amount of time controls and PWA spent in each attention state was more evenly distributed. When directly comparing attention patterns between linguistic and nonlinguistic tasks, PWA showed significantly more time in a high-attention state during the linguistic task as compared to the nonlinguistic task; however, controls showed no significant differences between linguistic and nonlinguistic tasks. CONCLUSIONS: This study provides new evidence that PWA experience a heightened state of vigilant attention when language processing demands are higher (during a linguistic task) than when language demands are lower (during a nonlinguistic task). Collectively, results of this study suggest that when processing language, PWA may allocate more attentional resources than when completing other kinds of cognitive tasks.

Elizabeth Usher memorial lecture. Models, mind maps, and metacognition: How theory is the true hero.

Within the educational context of identifying the critical ingredients of an effective speech-language pathologist, this paper highlights the centrality of theory in underpinning every level of our practice. A spotlight is placed on us knowing how language and communication work, what makes our interventions work, how we can make the most difference through our choices in therapy, and what makes both us and our clients respond. So, what are the critical ingredients of an effective speech-language pathologist, of an effective therapy, of an effective therapeutic alliance, and why is this so important? While there are many foundational and guiding habits upon which new graduates, early career, and experienced clinicians shape their practice, no one habit is regarded as more important than us exploring the theoretical underpinnings of what we are doing and why. To underscore the role of theory in our everyday practice, a discourse level intervention for people with aphasia is used as an exemplar to track the complex contribution of different theories to a single intervention. Discourse level interventions are relatively new on the scene in the area of acquired language disorders. Child language interventions, on the other hand, have frequently revolved around the story, aiming to bridge the oral-literate divide through the development of narrative structure. This paper will aim to weave its own story around discourse level interventions, combining the narrative genre with the everyday genres used by adults in conversation. I will highlight how this approach taps into lexical theories, sentence processing theories, discourse organisation, and the cognitive underpinnings of language, and closely examine how this multilayering of language in context may hold some of the answers to questions around generalisation, impact, and making the greatest difference to individuals.

Automated Analysis of Fluency Behaviors in Aphasia.

PURPOSE: This study explored the use of an automated language analysis tool, FLUCALC, for measuring fluency in aphasia. The purpose was to determine whether CLAN's FLUCALC command could produce efficient, objective outcome measures for salient aspects of fluency in aphasia. METHOD: The FLUCALC command was used on CHAT transcripts of Cinderella stories from people with aphasia (PWA; n = 281) and controls (n = 257) in the AphasiaBank database. RESULTS: PWA produced significantly fewer total words, fewer words per minute, more pausing, more repetitions, more revisions, and more phonological fragments than controls, with only one exception: The Wernicke's group was similar to the control group in percentage of filled pauses. Individuals with Broca's aphasia had significantly longer inter-utterance pauses and fewer total words than all other aphasia groups. Both the Broca's and conduction aphasia groups had higher percentages of phrase repetitions than the NABW (NotAphasicByWAB) group. The conduction aphasia group also had a higher percentage of phrase revisions than the NABW and the anomic aphasia groups. Principal components analysis revealed two principal components that accounted for around 60% of the variance and related to quantity of output, rate of speech, and quality of output. The Gaussian mixture models showed that the participants clustered in three groups, which corresponded predominantly to the controls, the nonfluent aphasia group, and the remaining aphasia groups (all classically fluent aphasia types). CONCLUSIONS: FLUCALC is an efficient way to measure objective fluency behaviors in language samples in aphasia. Automated analyses of objective fluency behaviors on large samples of adults with and without aphasia can produce measures that can be used by researchers and clinicians to better understand and track salient aspects of fluency in aphasia.

"It's day to day problems:" Experiences of people with aphasia who live alone.

PURPOSE: Living alone is increasing and associated with health and social risks. Aphasia compounds these risks but there is little research on how living alone interacts with aphasia. This study is a preliminary exploration of this issue. METHOD: Five people with aphasia who lived alone participated in two supported semi-structured interviews, with the second interview including sharing an artefact that held significance for living alone with aphasia. Interviews were recorded, transcribed verbatim, and analysed through reflexive thematic analysis. RESULT: Four themes encompassed meaning-making about living alone with aphasia: relationships and reliance on others; risk, vulnerability, and uncertainty; loneliness and time alone; self-reliance and the need to keep busy. Participants had to continuously manage and renegotiate daily challenges around living alone with aphasia. CONCLUSION: Living alone increases the risk of loneliness. For people with aphasia, the buffer against loneliness provided by social connection and meaningful activity may be more difficult to achieve because of communication challenges. While experiences vary, reliance on others, managing practical and administrative tasks, and negotiating risks are all important issues when alone. The intersection of living alone, loneliness, and living with aphasia needs more research, and more explicit clinical focus when discussing and planning intervention and support.

The role of input vs. output phonological working memory in narrative production: Evidence from case series and case study approaches.

Separable input and output phonological working memory (WM) capacities have been proposed, with the input capacity supporting speech recognition and the output capacity supporting production. We examined the role of input vs. output phonological WM in narrative production, examining speech rate and pronoun ratio - two measures with prior evidence of a relation to phonological WM. For speech rate, a case series approach with individuals with aphasia found no significant independent contribution of input or output phonological WM capacity after controlling for single-word production. For pronoun ratio, there was some suggestion of a role for input phonological WM. Thus, neither finding supported a specific role for an output phonological buffer in speech production. In contrast, two cases demonstrating dissociations between input and output phonological WM capacities provided suggestive evidence of predicted differences in narrative production, though follow-up research is needed. Implications for case series vs. case study approaches are discussed.

Identifying and Addressing Functional Communication Challenges in Patients With Behavioral Variant Frontotemporal Dementia.

PURPOSE: We describe the communication challenges of four patients with a neurodegenerative disorder consistent with behavioral variant frontotemporal dementia (bvFTD), characterized by early behavioral and personality changes. By describing their clinical profiles, we identify common barriers to functional communication in this population and provide recommendations for how speech-language pathologists (SLPs) might contribute to minimizing them. METHOD: Four patients with bvFTD were selected from a cohort of patients with progressive communication impairments. Three of them returned for at least one follow-up visit. Case histories are presented along with the results of comprehensive speech and language, neuropsychological, and neurological testing. RESULTS: At the time of initial evaluation, patients were between the ages of 54 and 66 years and had been experiencing symptoms for 1.5-6 years. Consistent with their bvFTD diagnoses, all patients had prominent behavioral and personality changes that impacted communication. Patients 1 and 2 also had mild aphasia at enrollment, primarily characterized by anomia and loss of word meaning. Patients 3 and 4 both had apraxia of speech and moderate-to-severe aphasia at enrollment with prominent anomia and agrammatism. All four patients had impaired executive functioning and relative sparing of visuospatial skills; episodic memory was also impaired for Patients 2 and 4. Even though functional communication was progressively limited for all patients, none of them received regular support from an SLP. CONCLUSIONS: This case series adds to a scant, but growing, literature demonstrating that patients with bvFTD have communication impairments. SLPs are uniquely positioned to identify barriers to functional communication and to provide tailored strategy training to the patients and their care partners over the course of their disease. Systematic evaluation of the efficacy of treatment in this population would be valuable. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25933762.

Moving Toward Anti-Ableist Practices in Aphasia Rehabilitation and Research: A Viewpoint.

PURPOSE: Ableism is a pervasive set of beliefs that regard nondisabled bodies and minds as ideal and necessary to live a full life. Ableism manifests for people with aphasia as stigma and discrimination based on their language ability. We assert that ableism contributes to decreased quality of life for people with aphasia and should be actively challenged and disrupted by clinicians and researchers in the field. METHOD: We applied the Health Stigma and Discrimination Framework (HSDF) to outline how stigma and discrimination are perpetuated against people with aphasia on the basis of language ability and their downstream health and social consequences. We presented this framework at the Clinical Aphasiology Conference in 2023 and share themes and challenges that arose from this discussion and from our ongoing learning. DISCUSSION: Applying the HSDF to aphasia outlined potential sequelae of ableism. We identified preliminary foci of future initiatives aimed at challenging ableist beliefs and practices and means to monitor the effectiveness of such interventions. Furthermore, we draw attention to the seeming tension between anti-ableist practices and traditional language rehabilitation goals. We assert that this tension may be a catalyst for fruitful discourse on how clinicians and researchers can resist ableism while honoring the lived experiences of people with aphasia and their goals for language rehabilitation. These discussions may be facilitated by existing models in disability studies (e.g., the political/relational model). CONCLUSIONS: Clinicians and researchers are well positioned to challenge ableism and minimize the resultant health and social impacts for people living with aphasia. Anti-ableist practices are not antithetical to aphasia rehabilitation and can be thoughtfully integrated into rehabilitation practices and discourse.

Safety-Seeking Behaviors and Anxiety Maintenance in People With Aphasia: A Viewpoint.

PURPOSE: People with aphasia (PWA) often experience higher levels of anxiety and social isolation than people without aphasia. Although the presence of anxiety is appreciated in PWA, literature examining the etiology and persistent nature of anxiety in PWA is underdeveloped. Safety-seeking behaviors, or maladaptive acts used by individuals to decrease anxiety from a feared outcome, have been reported as key facilitators of long-term anxiety toward feared situations across a variety of clinical populations. The purpose of this viewpoint is to explore the concept of safety-seeking behaviors and discuss their potential relevance to the maintenance of anxiety in PWA. We further discuss the distinction between maladaptive (i.e., safety seeking) and adaptive (i.e., coping) behaviors and how this knowledge may improve the quality of clinical services for PWA. CONCLUSIONS: The present review advocates for further exploration of the safety-seeking behaviors that are used by PWA. Until critical attention is given to this subject, clinicians may remain ill-equipped to identify and depict whether a self-management strategy is facilitative or inhibitive to PWA's communicative participation goals. Critically, a behavior that may be "maladaptive" for one individual may be "adaptive" for another. Future research should seek to identify common behavioral and cognitive strategies that PWA implement to reduce acute perceptions of anxiety. This knowledge may help facilitate holistic aphasia rehabilitation by allowing clinicians to foster conversations around behaviors that inhibit or promote successful communicative participation.

Social Support Mediates the Association Between Abilities and Participation After Stroke.

Stroke survivors face participation restrictions, yet little is known regarding how social support affects the association between an individual's abilities and participation. Through a Person-Environment-Occupation-Performance (PEOP) model lens, social support was examined as a potential mediator between ability and participation in cognitively and mobility-demanding activities for stroke survivors with aphasia (persons with aphasia [PWA]) and without aphasia (persons without aphasia [PWOA]). A cross-sectional design, including PWA (n = 50) and PWOA (n = 59) examined associations among person factors (physical impairment, cognition), an environmental factor (social support), and occupational participation through cognitively- and mobility-demanding activity subscales of the Activity Card Sort. Cognition was associated with participation in cognitively demanding activities for both groups, though social support was a mediator only for PWA. Physical impairment was associated with participation in mobility-demanding activities for PWOA, though social support did not mediate that relationship. Social support is key to PWA participating in cognitively demanding activities post-stroke.

Social Support's Role in Tasks that Require Cognition or Mobility for Stroke Survivors with and without AphasiaAfter a stroke, people can face difficulties doing the things they need and want to do in their daily life. Sometimes a stroke can cause aphasia, a disorder that can make it hard for someone to communicate. Social support occurs when one person helps someone do the things they need and want to do. Certain tasks may require different skills, like cognition (being able to think) or mobility (being able to move). Results showed that cognition is important to do tasks that require a lot of thinking for people who experience a stroke and social support is essential for people with aphasia to do tasks that require a lot of thinking. In addition, mobility is important to do tasks that require walking or movement for people without aphasia.

Gesture's Role in the Communication of Adults With Different Types of Aphasia.

PURPOSE: Adults with aphasia gesture more than adults without aphasia. However, less is known about the role of gesture in different discourse contexts for individuals with different types of aphasia. In this study, we asked whether patterns of speech and gesture production of individuals with aphasia vary by aphasia and discourse type and also differ from the speech and gestures produced by adults without aphasia. METHOD: We compared the amount, diversity, and complexity of speech and gesture production in adults with anomic or Broca's aphasia and adults with no aphasia (n = 20/group) in their first- versus third-person narratives. RESULTS: Adults with Broca's aphasia showed the lowest performance in their amount, diversity, and complexity of speech production, followed by adults with anomic aphasia and adults without aphasia. This pattern was reversed for gesture production. Speech and gesture production also varied by discourse context. Adults with either type of aphasia used a lower amount of and less diverse speech in third-person than in first-person narratives; this pattern was also reversed for gesture production. CONCLUSIONS: Overall, our results provide evidence for a compensatory role of gesture in aphasia communication. Adults with Broca's aphasia, who showed the greatest speech production difficulties, also relied most on gesture, and this pattern was particularly pronounced in the third-person narrative context.

Poststroke Communication Ability Predicts Patient-Informant Discrepancies in Reported Activities and Participation.

BACKGROUND: Participation in life situations has been identified by people with aphasia (PWA) as an ultimate outcome of rehabilitation and is often measured with patient-reported outcome measures (PROMs) or informant-reported measures. It is known that PWA and informants do not always produce similar scores on measures of activities and participation. However, systematic differences between PWA and informants and the causes of these differences are not well understood. Here, we investigated these differences as a function of language impairment, perceived level of activity and participation success, and depressive symptoms. METHOD: Participants were 29 PWA-informant dyads who completed a performance-based language assessment and three measures related to different aspects of activities and participation. Outcome variables were PWA-informant difference scores in the activities and participation measures. RESULTS: PWA ratings of activities and participation were not statistically significantly associated with performance-based language severity. Hierarchical regression models with both language impairment and informant-reported scores as predictor variables explained 53%-71% of the variance in PWA-informant difference scores (all p < .05). In particular, mild communication challenges were associated with the PWA reporting significantly worse participation than the informant perceived. In contrast, more severe communication challenges were associated with the PWA reporting significantly better participation than the informant perceived. DISCUSSION: These findings highlight the importance of measuring participation by PROM. The PWA's experience of participation is not related to their level of language impairment and is predictably different from their care partners' perspective. As others have also reported, "mild" aphasia is not so mild to the PWA. Similarly, "severe" may not be so severe to the PWA. Further research is needed to connect these findings with counseling and caregiver education. Research on response processes (e.g., response shift) is also warranted.

Self-Reported Home Program Adherence by People With Aphasia: Exploring Construct Validity.

PURPOSE: The study purpose was to compare the practice patterns captured by self-reported logbook data and those recorded by a computerized home program application. The current study is part of a larger single-case research design study aimed at investigating the effect of logbook use on home program adherence in people with aphasia poststroke. METHOD: Data from six adults with chronic aphasia with interest in improving their reading were used in this secondary analysis. Participants completed reading comprehension therapy tasks using a mobile application and tablet. The activities were self-directed and designed for people with aphasia to complete independently. We created an aphasia-friendly logbook based on best practices to allow participants to record their estimated total minutes practiced. Participants received instructions to practice the reading therapy application 80 min a day 7 days a week for the duration of the study. We calculated the difference in the total time per day recorded by each participant to the application data collected. RESULTS: All participants used the logbook to record their practice. There was a strong relationship between self-reported logbook practice and application-recorded practice for four of the six participants. Individual differences were noted and explored. CONCLUSION: These results suggest that some people with aphasia can use logbooks with aphasia-friendly modifications to accurately estimate the amount of practice completed outside of therapy sessions.

Response Latencies During Confrontation Picture Naming in Aphasia: Are Proxy Measurements Sufficient?

PURPOSE: Anomia, or word-finding difficulty, is a prevalent and persistent feature of aphasia, a neurogenic language disorder affecting millions of people in the United States. Anomia assessments are essential for measuring performance and monitoring outcomes in clinical settings. This study aims to evaluate the reliability of response time (RT) annotation based on spectrograms and assess the predictive utility of proxy RTs collected during computerized naming tests. METHOD: Archival data from 10 people with aphasia were used. Trained research assistants phonemically transcribed participants' responses, and RTs were generated from the onset of picture stimulus to the initial phoneme of the first complete attempt. RTs were measured in two ways: hand-generated RTs (from spectrograms) and proxy RTs (automatically extracted online). Interrater agreement was evaluated based on interclass correlation coefficients and generalizability theory tools including variance partitioning and the φ-coefficient. The predictive utility of proxy RTs was evaluated within a linear mixed-effects framework. RESULTS: RT annotation reliability showed near-perfect agreement across research assistants (φ-coefficient = .93), and the variance accounted for by raters was negligible. Furthermore, proxy RTs significantly and strongly predicted hand-annotated RTs (R2 = ~0.82), suggesting their utility as an alternative measure. CONCLUSIONS: The study confirms the reliability of RT annotation and demonstrates the predictive utility of proxy RTs in estimating RTs during computerized naming tests. Incorporating proxy RTs can enhance clinical assessments, providing additional information for cognitive measurement. Further research with larger samples and exploring the impact of using proxy RTs in different psychometric models could optimize clinical protocols and improve communication interventions for individuals with aphasia.

Modality Synchronization When People With Aphasia Read With Text-to-Speech Support.

PURPOSE: Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. METHOD: Nine adults with aphasia had their eye movements tracked while processing TTS passages at a preselected default rate of 150 words per minute. Modality synchronization occurred whenever fixation on a written word occurred during the time span beginning 300 ms before auditory presentation and ending at the next word's initiation. Correlations between standardized test scores, unsupported reading rate, and modality synchronization percentages were informative about the association of aphasia and reading impairment severity with achievement of synchronicity. RESULTS: Three participants demonstrated consistent modality synchronization; average synchronicity ranged from 67% to 76% of passage words. One participant displayed inconsistent synchronization within passages and achieved an average of 58%. The remaining five participants rarely achieved synchronization, with fixations typically lagging substantially behind the auditory presentation. A significant positive correlation occurred between paragraph reading comprehension test scores and modality synchronization percentages. CONCLUSIONS: A default TTS presentation rate does not result in dual modality synchronization for most people with aphasia. This lack of synchronization may contribute to inconsistencies in the benefit people with aphasia experience when provided with TTS support.
