"I Could Not Talk . . . She Did Everything . . . She's Now My Sister": People With Aphasia's Perspectives on Friends Who Stuck Around.

PURPOSE: Aphasia may decrease the capacity to develop and maintain friendships. The aim of this study was to better understand the perspectives of people with aphasia on why some friendship bonds remain strong and some do not. Furthermore, we wanted to explore how age and aphasia severity shape views on friendship. METHOD: We interviewed 27 people with aphasia about their experiences of friendship before and after the onset of aphasia. We then used framework analysis and reflexive thematic analysis to interpret the interview data. RESULTS: From the interviews, we created four major themes concerning how friend relationships had been impacted by aphasia: (a) Not all bonds have the same chance of surviving the onset of aphasia; (b) people with aphasia's closest friends took active steps to keep relationships strong; (c) if friends knew some basic information about aphasia, bonds would stay stronger; (d) positive affective aspects of friendship play an important role in keeping bonds strong. We also noted differences in friendship experiences that appeared to be influenced by age and aphasia severity of participants. CONCLUSIONS: Interview data provided actionable ideas including focusing on friends who are likely to be responsive to help with maintaining the friendship, providing them with strategies to keep the friendship active and communication meaningful, and acknowledging the positive impact that this will have on the friend recovering from aphasia. More research is needed to develop programs that empower people with aphasia to maintain their friendships. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.24688671.

Online Aphasia Groups: Navigating Issues of Voice and Identity.

PURPOSE: Participation in aphasia groups is associated with increased communication, reduced feelings of social isolation, and increased quality of life. Despite the growing popularity of online aphasia groups, little is known about how to manage conversation in this format. We examined online aphasia book club sessions to examine how the facilitator supported group members' participation in conversation. METHOD: Interactional sociolinguistic discourse analysis was used to analyze the behaviors and actions of the facilitator and group members. Qualitative data for this study were drawn from four recorded online aphasia book club sessions held through a university's free aphasia clinic on the Zoom web-conferencing platform. RESULTS: Sociolinguistic discourse analysis revealed strategic facilitator behaviors that served to (a) give members with varying levels of verbal language abilities voice, (b) foreground or background aspects of voice, and (c) minimize her own voice to promote interactional symmetry between herself and group members. CONCLUSIONS: Identity formed the backdrop for facilitators' actions when leading online groups, guiding decisions about who got to talk, when, for how long, through what modality, and about what topics. A better understanding of the interactions that occur online, such as how to develop and protect the identities of group members, could equip facilitators with the tools necessary for facilitating positive, engaging aphasia therapy groups online.

Reliability of a Linguistic Segmentation Procedure Specified by Systemic Functional Linguistics to Examine Extemporaneous Speech.

PURPOSE: Extemporaneous speech tasks provide an ecologically valid sample to examine speech acoustics, but differing methodologies exist in the literature for segmentation. Therefore, the purpose of this study was to examine the utility and reliability of a segmentation approach for extemporaneous speech specified by systemic functional linguistics (SFL) and its potential research and clinical applications. METHOD: Ten speakers without communication disorders served as participants in this study, and they responded to self-selected extemporaneous speaking prompts. Two expert analysts and one clinician analyst utilized a segmentation procedure specified by SFL to segment the extemporaneous speech samples into clauses and clause complexes. Intra- and interrater reliability were calculated for each analyst and pair of analysts. Acoustic measures of duration, speech rate, and intercomplex pause durations were calculated for each clause complex. RESULTS: Analyses for both intra- and interrater reliability revealed high percent agreement that was significantly greater than chance for expert and clinician analysts and between each pair of analysts (p < .001). Acoustic analyses revealed expected variation in number and duration of spoken syllables of clause complexes between and within speakers. CONCLUSIONS: The segmentation approach for extemporaneous speech specified by SFL is a reliable method for trained analysts that is informed by lexico-grammar and allows for acoustic measurement of speech production. It is also a reliable method for clinician analysts for speakers without communication disorders, and future work will investigate its utility for speakers with motor speech disorders.

Stuttering, Intersectionality, and Identity: A Qualitative Analysis of the Experiences of Lesbian, Gay, and Bisexual Individuals Who Stutter.

PURPOSE: Speech-language pathologists are influential in shaping identity development for individuals who stutter, particularly as it relates to communication. This study investigated the experiences of lesbian, gay, and bisexual individuals who stutter to learn more about how multiple marginalized identities affect their psychosocial experiences. METHOD: Semi-structured interviews were conducted with seven individuals who stutter with lesbian, gay, and bisexual identities. Participants ranged in age from 22 to 60 years. Data were analyzed for themes and categories by using interpretive phenomenological analysis. RESULTS: Four primary themes were identified: (a) the importance of visibility and shared social identity connections for affirmation; (b) effects of oppressive social expectations on identity; (c) intersectionality of stuttering, gay, lesbian, and bisexual identities; and (d) effects of not being affirmed for identity. DISCUSSION: Results are discussed in the context of identity affirmation and intersectionality. Through an understanding of identity formation and psychosocial experiences of lesbian, gay, and bisexual individuals who stutter, speech-language pathologists can use identity-affirmative practices to support individuals who stutter and mitigate stigmatizing experiences. Implications focus on suggestions for the provision of identity-affirming speech-language pathology practices for students who stutter.

A scoping review of friendship intervention for older adults: lessons for designing intervention for people with aphasia.

PURPOSE: Map the landscape of friendship interventions/programs for older adults to guide intervention/program development inclusive of the unique needs of older people with aphasia (PWA). METHODS: A search query of multiple databases was completed for articles published before 4 January 2021. Studies included all the following: (1) participants aged 55 years or older; (2) addressed an intervention/program designed to prevent social isolation and/or friendship loss; (3) used an outcome variable related to social isolation and/or friendship; and (4) published in a peer-reviewed journal. Title and abstract screening were conducted using Covidence software, which tracked disagreements across the study team. All studies included in the full-text review were identified as relevant by a minimum of two study authors, and a consensus was reached on all full-text reviews. Data were extracted according to (1) theoretical frameworks used; (2) interventionist and discipline; (3) participant characteristics; (4) intervention/program replicability; (5) format of intervention/program; (6) measures used in the intervention/programs; (7) and, reported effects of intervention/programs on individuals. RESULTS: A total of 40 articles with 42 intervention/programs were included and represented 4584 intervention/program participants ranging in age from 40 to 104 years. Intervention/programs involved a wide range of theoretical frameworks (e.g., theories of loneliness, feminist theory, positive psychology). Disciplines such as psychology and exercise science informed intervention/programs. Interventionists included many types of individuals like therapists, volunteers and home health aides. Intervention/programs often lacked adequate description for replication and included individual and group formats, most commonly delievered in the participants homes. Outcomes usually included self-report measures of loneliness, social networks, or well-being, and intervention/programming was primarily educational, activity-based, or networking-based in nature. CONCLUSIONS: The intervention/programs reviewed yield important lessons to support innovation in developing friendship intervention/programs for older PWA as most yielded positive results and were acceptable to participants.IMPLICATIONS FOR REHABILITATIONPeople with aphasia want their friendships addressed as part of their rehabilitation; however, the research literature has little guidance in this area.Studies reviewed of friendship intervention/programs for older adults yielded helpful lessons for consideration in developing this type of intervention/programming for people with aphasia.Interprofessional teams made up of rehabilitation professionals should address friendship for people with aphasia in both research and clinical practice.

Conversation as an Outcome of Aphasia Treatment: A Systematic Scoping Review.

PURPOSE: Conversation-focused speech-language pathology services are a top priority for people living with aphasia, but little is known about how researchers measure conversation as an outcome of treatment. This scoping review was undertaken to systematically review the evidence regarding the measurement of conversation in aphasia studies and to identify current practices and existing gaps. METHOD: A systematic literature search was conducted for studies published between January 1995 and September 2019 in multiple electronic databases. Covidence software was used to manage search results, study selection, and data charting processes. Data were extracted from each study and then collated and organized to elucidate the breadth of approaches, tools, or procedures oriented to measuring conversation as an outcome and identify gaps in the existing literature. RESULTS: The systematic search of the literature resulted in 1,244 studies. A total of 64 studies met inclusion criteria and were included in the review. The review summarizes the various tools and procedures used to measure conversation as an outcome of aphasia intervention, including variations in data collection and analysis procedures. The review also evaluates the quality of conversation measures in terms of psychometric properties and informal measures of validity. There was a total of 211 measures used across the 64 studies. CONCLUSIONS: While there was no clear measure that was objectively superior, several measures show promise and warrant future exploration. Some of the orientations, conceptualizations, and procedures we have presented can be seen as options that might be included in a future conversation-focused core outcome set.

"If You Just Stay With Me and Wait You'll Get an Idea of What I'm Saying": The Communicative Benefits of Time for Conversational Self-Repair for People With Aphasia.

PURPOSE: This study investigated the communicative benefits of self-repair during conversation for persons with aphasia (PWAs). Self-repair of trouble sources is an interactional priority that emphasizes autonomy and competence. Of equal importance, conversationalists desire to minimize silences and work together to ensure forward movement (progressivity) of conversation. Simultaneously achieving progressivity and self-repair is challenging in aphasia, and PWAs and their partners often make trade-off decisions between these two activities. Conversation-level aphasia interventions usually focus on supportive techniques that promote participation while maintaining progressivity, effectively favoring progressivity over self-repair. This study evaluates the benefits of an alternative approach that shifts the emphasis to self-repair, thereby highlighting potential trade-off costs of routinely forgoing self-repair to achieve progressivity. METHOD: Ten people with mild-to-moderate aphasia each held two conversations with two different partners. When trouble sources characterized by silent and/or filled pauses occurred, partners maintained a supportive and engaged stance, allowing PWAs time to self-repair. We analyzed language produced during these "edited turns" using three paradigms considering form, content, and use. RESULTS: The data yielded 311 edited turns. For form, on average, each edited turn resulted in 3.72 words; for content, most edited turns contained autobiographical information; for use, approximately 40% of edited turns introduced new information, and 40% added to the ongoing topic. The remainder were either ambiguous or comments such as, "I can't think of it." CONCLUSIONS: When given engaged support and time to self-repair, PWAs contributed meaningful personal information to conversations for approximately 80% of edited turns. Importantly, self-repair often resulted in self-expression that directed the conversation, which is a communicative role critical for empowering agency and identity. This research opens a dialogue about benefits and limitations of approaches that prioritize either progressivity or self-repair and how to balance the two to optimize therapeutic benefits for each individual.

Toward Empowering Conversational Agency in Aphasia: Understanding Mechanisms of Topic Initiation in People With and Without Aphasia.

PURPOSE: This study examined topic initiation (TI) in conversations involving people with aphasia (PWA), matched people without aphasia (M-PWoA), and speech-language pathologists who were their conversation partners (SLP-Ps). For each speaker type, we analyzed patterns of distribution of typical mechanisms of TI and patterns of simultaneous use of multiple TI mechanisms. Lastly, we examined associations between use of simultaneous TI mechanisms and communicative success. METHOD: Twenty PWA and 20 M-PWoA each participated in two conversations with SLP-Ps. Conversation samples were analyzed for TI locations and mechanisms, with results tallied for each speaker type following a published typology. A measure of communicative success was applied to TI utterances. Rank-order correlations were conducted to evaluate the patterns of distribution of the TI mechanisms between speaker types and the patterns of multiple mechanism usage between speaker types. Descriptive analysis was conducted to provide additional insight to the TI behaviors of each speaker type and to evaluate the relationship between multiple TI mechanisms and communicative success. RESULTS: All speaker types used cohesion most often to achieve TI. PWA used an abrupt method of TI (noncoherent TI) more often than other speaker types. A single mechanism of TI was used most often by all speaker types, except for SLP-Ps when they were in conversations with PWA. In this case, SLP-Ps most often used two or more layered mechanisms of TI. SLP-Ps also used a highly salient TI mechanism with greater frequency when speaking with PWA than observed between other speaker types. When PWA layered mechanisms of TI, they appeared to be more likely to achieve better communicative success. CONCLUSIONS: Specific, teachable behaviors such as favoring certain TI mechanisms and using multiple TI mechanisms may improve communicative success during TI for PWA. Furthermore, findings suggest that SLP-Ps modify their TI behaviors when speaking to PWA. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.17699423.

Effect Sizes in Single-Case Aphasia Studies: A Comparative, Autocorrelation-Oriented Analysis.

Purpose In single-case treatment studies, researchers may compare client performance during a baseline, nontreatment phase(s) to client performance during intervention phases. Autocorrelation in the data series gathered during such studies increases the likelihood that analysts will detect or fail to detect meaningful differences between baseline and treatment phase data. We examined the impact that autocorrelation has on 4 effect size calculation methods when these methods are applied to data generated by people with aphasia during anomia treatment studies. The effect sizes we selected were Busk and Serlin's d, Young's C, nonoverlap of all pairs, and Tau-U. We hypothesized that d and C would be influenced by autocorrelation, whereas nonoverlap of all pairs and Tau-U would not. Method We extracted 173 highly autocorrelated data series from published investigations of treatments for anomia. These data series were then "cleansed" of autocorrelation through the use of an autoregressive integrated moving average (ARIMA) process. The 4 effect size calculation methods were used to derive an effect size for each published and each corresponding ARIMA-tized data series. The published and ARIMA-tized effect sizes associated with each calculation method were then compared. Results For all of the 4 effect sizes, statistically significant differences existed between the published effect sizes and the ARIMA-tized effect sizes. Conclusions All 4 of the methods were influenced by autocorrelation. Further research that develops effect size calculation methods that are not influenced by autocorrelation will help to improve the quality of single-case studies.

Humour in clinical-educational interactions between graduate student clinicians and people with aphasia.

BACKGROUND: During clinical interactions, clinicians and people with aphasia (PWA) use humour and laughter for a range of purposes, most of which contribute to friendly interactions in which the participants appear to develop a positive regard for one another. Moreover, humour is a vital component of facework, or the processes interactants engage in to protect their own and one another's well-respected, public personas. AIMS: To examine the ways in which speech-language pathology graduate student clinicians enlist humour during one-on-one therapy sessions for PWA. METHODS & PROCEDURES: Three dyads composed of one graduate student clinician and one person with aphasia acted as participants. We recorded six routine individual aphasia therapy sessions that were each about 60 min in length. All sessions were orthographically transcribed by a trained research assistant. Transcriptions included verbal and non-speech communication (e.g., facial expressions, gestures, writing). For analysis, we employed an ethnographic microanalysis framework. First, by focusing on laughter produced by the interactants, we identified segments in the data that involved clinician-led humour. Next, we sought to understand patterns that represented potential functions of humour. We consciously sought out instances that did not appear consistent with our developing understanding of the functions of humour. Such negative cases were used to refine our description of how graduate student clinicians use humour. Other verification procedures included member checking and peer debriefing. OUTCOMES & RESULTS: The findings illustrate that graduate student clinicians use laughter and humour for a range of interactional purposes when interacting with clients with aphasia. Humour was used as a means of (1) softening exposure to client's errors, (2) equalizing interactional power, (3) mitigating errors made by graduate student clinicians, (4) supporting own narrative production and (5) demonstrating affiliation. CONCLUSIONS & IMPLICATIONS: The current study demonstrates that graduate student clinicians we observed, like the clinicians studied in previous investigations of humour in therapeutic encounters, possess the humour and laughter-related skills that help to foster positive interactions with PWA. Future investigations of the source of these skills should determine if students are adept because of natural abilities or if students can be taught to be better interactants via instruction. Findings emanating from these studies can be used to inform curriculum design, which will in turn help our field better meet the needs of clients.

Methods to model and predict the ViewRay treatment deliveries to aid patient scheduling and treatment planning.

A software tool is developed, given a new treatment plan, to predict treatment delivery time for radiation therapy (RT) treatments of patients on ViewRay magnetic resonance image-guided radiation therapy (MR-IGRT) delivery system. This tool is necessary for managing patient treatment scheduling in our clinic. The predicted treatment delivery time and the assessment of plan complexities could also be useful to aid treatment planning. A patient's total treatment delivery time, not including time required for localization, is modeled as the sum of four components: 1) the treatment initialization time; 2) the total beam-on time; 3) the gantry rotation time; and 4) the multileaf collimator (MLC) motion time. Each of the four components is predicted separately. The total beam-on time can be calculated using both the planned beam-on time and the decay-corrected dose rate. To predict the remain-ing components, we retrospectively analyzed the patient treatment delivery record files. The initialization time is demonstrated to be random since it depends on the final gantry angle of the previous treatment. Based on modeling the relationships between the gantry rotation angles and the corresponding rotation time, linear regression is applied to predict the gantry rotation time. The MLC motion time is calculated using the leaves delay modeling method and the leaf motion speed. A quantitative analysis was performed to understand the correlation between the total treatment time and the plan complexity. The proposed algorithm is able to predict the ViewRay treatment delivery time with the average prediction error 0.22min or 1.82%, and the maximal prediction error 0.89 min or 7.88%. The analysis has shown the correlation between the plan modulation (PM) factor and the total treatment delivery time, as well as the treatment delivery duty cycle. A possibility has been identified to significantly reduce MLC motion time by optimizing the positions of closed MLC pairs. The accuracy of the proposed prediction algorithm is sufficient to support patient treatment appointment scheduling. This developed software tool is currently applied in use on a daily basis in our clinic, and could also be used as an important indicator for treatment plan complexity.

The treatment of anomia in Sesotho: a case for parametric aphasiology.

South Africa, as a multilingual country, offers the opportunity for examining the interaction between aphasic symptomatology and the parameters of language. Effective intervention techniques depend on an understanding of clinical linguistics. This article describes an intervention study with two Sesotho-speaking individuals with anomia. Sesotho as a noun class and syllable-timed language offers the opportunity to study the influence of cueing techniques, which are based on such linguistic parameters. Word lists were designed using non-aphasic participants and three cueing techniques for anomia were evaluated over a period of 4 months. Findings suggested a positive response to the techniques of true phonemic cueing and prosodic cueing, whereas initial phonemic cueing (a technique commonly used for English-speaking anomic patients) had no impact. This supports the need for a parametrically informed approach to aphasia therapy and strengthens the recommendation that a linguistic basis is paramount in the training of effective clinicians.
