Conversational Speech Behaviors Are Context Dependent.

PURPOSE: According to the interpersonal synergy model of spoken dialogue, interlocutors modify their communicative behaviors to meet the contextual demands of a given conversation. Although a growing body of research supports this postulation for linguistic behaviors (e.g., semantics, syntax), little is understood about how this model applies to speech behaviors (e.g., speech rate, pitch). The purpose of this study is to test the hypothesis that interlocutors adjust their speech behaviors across different conversational tasks with different conversational goals. METHOD: In this study, 28 participants each engaged in two different types of conversations (i.e., relational and informational) with two partners (i.e., Partner 1 and Partner 2), yielding a total of 112 conversations. We compared six acoustic measures of participant speech behavior across conversational task and partner. RESULTS: Linear mixed-effects models demonstrated significant differences between speech feature measures in informational and relational conversations. Furthermore, these findings were generally robust across conversations with different partners. CONCLUSIONS: Results suggest that contextual demands influence speech behaviors. These findings provide empirical support for the interpersonal synergy model and highlight important considerations for assessing speech behaviors in individuals with communication disorders.

AI vs academia: Experimental study on AI text detectors' accuracy in behavioral health academic writing.

Artificial Intelligence (AI) language models continue to expand in both access and capability. As these models have evolved, the number of academic journals in medicine and healthcare which have explored policies regarding AI-generated text has increased. The implementation of such policies requires accurate AI detection tools. Inaccurate detectors risk unnecessary penalties for human authors and/or may compromise the effective enforcement of guidelines against AI-generated content. Yet, the accuracy of AI text detection tools in identifying human-written versus AI-generated content has been found to vary across published studies. This experimental study used a sample of behavioral health publications and found problematic false positive and false negative rates from both free and paid AI detection tools. The study assessed 100 research articles from 2016-2018 in behavioral health and psychiatry journals and 200 texts produced by AI chatbots (100 by "ChatGPT" and 100 by "Claude"). The free AI detector showed a median of 27.2% for the proportion of academic text identified as AI-generated, while commercial software Originality.AI demonstrated better performance but still had limitations, especially in detecting texts generated by Claude. These error rates raise doubts about relying on AI detectors to enforce strict policies around AI text generation in behavioral health publications.

Lexical Alignment is Pervasive Across Contexts in Non-WEIRD Adult-Child Interactions.

Lexical alignment, a communication phenomenon where conversational partners adapt their word choices to become more similar, plays an important role in the development of language and social communication skills. While this has been studied extensively in the conversations of preschool-aged children and their parents in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) communities, research in other pediatric populations is sparse. This study makes significant expansions on the existing literature by focusing on alignment in naturalistic conversations of school-aged children from a non-WEIRD population across multiple conversational tasks and with different types of adult partners. Typically developing children aged 5 to 8 years (n = 45) engaged in four semi-structured conversations that differed by task (problem-solving vs. play-based) and by partner (parent vs. university student), resulting in a corpus of 180 conversations. Lexical alignment scores were calculated and compared to sham conversations, representing alignment occurring at the level of chance. Both children and adults coordinated their conversational utterances by re-using or aligning each other's word choices. This alignment behavior persisted across conversational tasks and partners, although the degree of alignment was moderated by the conversational context. These findings suggest that lexical alignment is a robust phenomenon in conversations between school-age children and adults. Furthermore, this study extends lexical alignment findings to a non-WEIRD culture, suggesting that alignment may be a coordination strategy employed by adults and children across diverse linguistic and cultural backgrounds.

An ecological examination of early adolescent e-cigarette use: A machine learning approach to understanding a health epidemic.

E-cigarette use among adolescents is a national health epidemic spreading faster than researchers can amass evidence for risk and protective factors and long-term consequences associated with use. New technologies, such as machine learning, may assist prevention programs in identifying at risk youth and potential targets for intervention before adolescents enter developmental periods where e-cigarette use escalates. The present study utilized machine learning algorithms to explore a wide array of individual and socioecological variables in relation to patterns of lifetime e-cigarette use during early adolescence (i.e., exclusive, or with tobacco cigarettes). Extant data was used from 14,346 middle school students (Mage = 12.5, SD = 1.1; 6th and 8th grades) who participated in the Utah Prevention Needs Assessment. Students self-reported their substance use behaviors and related risk and protective factors. Machine learning algorithms examined 112 individual and socioecological factors as potential classifiers of lifetime e-cigarette use outcomes. The elastic net algorithm achieved outstanding classification for lifetime exclusive (AUC = .926) and dual use (AUC = .944) on a validation test set. Six high value classifiers were identified that varied in importance by outcome: Lifetime alcohol or marijuana use, perception of e-cigarette availability and risk, school suspension(s), and perceived risk of smoking marijuana regularly. Specific classifiers were important for lifetime exclusive (parent's attitudes regarding student vaping, best friend[s] tried alcohol or marijuana) and dual use (best friend[s] smoked cigarettes, lifetime inhalant use). Our findings provide specific targets for the adaptation of existing substance use prevention programs to address early adolescent e-cigarette use.

Barriers to accessing telepsychology services questionnaire: Structure and language-based performance in a sample of Latinx caregivers.

A lack of validated measures to examine barriers to youth telepsychology services among Latinx families limits research that could identify targets for reducing mental health disparities. We developed and validated the Latinx Barriers to Accessing Telepsychology Services (Latinx BATS) questionnaire, a brief multidimensional measure for caregivers of youths. Participants included 511 Latinx caregivers of youths Ages 6-18 (English n = 275, Spanish n = 236) who completed the Latinx BATS and reported on telepsychology service utilization and youth mental health problems. Caregivers whose youths had clinically elevated mental health problems were more likely to report barriers to accessing youth telepsychology services compared to nonclinical youths. Commonly endorsed barriers included concerns that the child would be distracted and not get much benefit, and that providers would be unfamiliar with the family's culture or would not pick up on nuances and emotions. Loadings from an exploratory graph analysis returned four-factors: relational, acceptability, quality, and access concerns. Network centrality measures identified provider knowledge regarding community resources and Latinx culture as important targets for reducing barriers to youth telepsychology services. Confirmatory factor analyses were then conducted and found that the four-factor structure outperformed a single-factor solution. The four-factor structure was similar for the English and Spanish versions of the Latinx BATS, but the strength of item loadings varied across languages. Implications for the use of the Latinx BATS in research and clinical practice are discussed including specific strategies for reducing these obstacles to care among Latinx families.

Prevalence and Cost of Routine Preoperative Care for Low-Risk Cataract Surgery a Decade after Choosing Wisely.

PURPOSE: Examine the frequency and cost of procedural clearance tests and examinations in preparation for low-risk cataract surgery among members of a commercial healthcare organization in the United States. Determine what characteristics most strongly predict receipt of preoperative care and the probability that preoperative care impacts postsurgical adverse events. DESIGN: Retrospective healthcare claims analysis and medical records review from a large, blended-health organization headquartered in Western Pennsylvania. PARTICIPANTS: Members aged ≥ 65 years who were continuously enrolled 6 months before and after undergoing cataract surgery from 2018 to 2021 and had approved surgery claims. METHODS: Preoperative exams or tests occurring in the 30 days before surgery were identified via procedural and diagnosis codes on claims of eligible members (e.g., Current Procedural Terminology codes for blood panels and preprocedural International Classification of Diseases, 10th Revision, Clinical Modification codes). Prevalence and cost were directly estimated from claims; variables predictive of preoperative care receipt and adverse events were tested using mixed effects modeling. MAIN OUTCOME MEASURES: Total costs, prevalence, and strength of association as indicated by odds ratios. RESULTS: Up to 42% of members undergoing cataract surgery had a physician office visit for surgical clearance, and up to 23% of members had testing performed in isolation or along with clearance visits. The combined costs for the preoperative visits and tests were $4.3 million (approximately $107-$114 per impacted member). There was little difference in member characteristics between those receiving and not receiving preoperative testing or exams. Mixed effects models showed that the most impactful determinants of preoperative care were the surgical facility and member's care teams; for preoperative testing, facilities were a stronger predictor than care teams. Adverse events were rare and unassociated with receipt of preoperative testing, exams, or a combination of the two. CONCLUSIONS: Rates of routine preoperative testing before cataract surgery appear similar to those prior to the implementation of the Choosing Wisely campaign, which was meant to reduce this use. Additionally, preoperative evaluations, many likely unnecessary, were common. Further attention to and reconsideration of current policies and practice for preoperative care may be warranted, especially at the facility level.

Perceptual Learning of Dysarthria in Adolescence.

PURPOSE: As evidenced by perceptual learning studies involving adult listeners and speakers with dysarthria, adaptation to dysarthric speech is driven by signal predictability (speaker property) and a flexible speech perception system (listener property). Here, we extend adaptation investigations to adolescent populations and examine whether adult and adolescent listeners can learn to better understand an adolescent speaker with dysarthria. METHOD: Classified by developmental stage, adult (n = 42) and adolescent (n = 40) listeners completed a three-phase perceptual learning protocol (pretest, familiarization, and posttest). During pretest and posttest, all listeners transcribed speech produced by a 13-year-old adolescent with spastic dysarthria associated with cerebral palsy. During familiarization, half of the adult and adolescent listeners engaged in structured familiarization (audio and lexical feedback) with the speech of the adolescent speaker with dysarthria; and the other half, with the speech of a neurotypical adolescent speaker (control). RESULTS: Intelligibility scores increased from pretest to posttest for all listeners. However, listeners who received dysarthria familiarization achieved greater intelligibility improvements than those who received control familiarization. Furthermore, there was a significant effect of developmental stage, where the adults achieved greater intelligibility improvements relative to the adolescents. CONCLUSIONS: This study provides the first tranche of evidence that adolescent dysarthric speech is learnable-a finding that holds even for adolescent listeners whose speech perception systems are not yet fully developed. Given the formative role that social interactions play during adolescence, these findings of improved intelligibility afford important clinical implications.

The Influence of Sensorineural Hearing Loss on the Relationship Between the Perception of Speech in Noise and Dysarthric Speech.

PURPOSE: The ability to understand speech under adverse listening conditions is highly variable across listeners. Despite this, studies have found that listeners with normal hearing display consistency in their ability to perceive speech across different types of degraded speech, suggesting that, for at least these listeners, global skills may be involved in navigating the ambiguity in speech signals. However, there are substantial differences in the perceptual challenges faced by listeners with normal and impaired hearing. This study examines whether listeners with sensorineural hearing loss demonstrate the same type of consistency as normal-hearing listeners when processing neurotypical (i.e., control) speech that has been degraded by external noise and speech that is neurologically degraded such as dysarthria. METHOD: Listeners with normal hearing (n = 31) and listeners with sensorineural hearing loss (n = 36) completed an intelligibility task with neurotypical speech in noise and with dysarthric speech in quiet. RESULTS: Findings were consistent with previous work demonstrating a relationship between the ability to perceive neurotypical speech in noise and dysarthric speech for listeners with normal hearing, albeit at a higher intelligibility level than previously observed. This relationship was also observed for listeners with hearing loss, although listeners with more severe hearing losses performed better with dysarthric speech than with neurotypical speech in noise. CONCLUSIONS: This study demonstrated a high level of consistency in intelligibility performance for listeners across two different types of degraded speech, even when those listeners were further challenged by the presence of sensorineural hearing loss. Clinical implications for both listeners with hearing loss and their communication partners with dysarthria are discussed.

Speech Entrainment in Adolescent Conversations: A Developmental Perspective.

PURPOSE: Defined as the similarity of speech behaviors between interlocutors, speech entrainment plays an important role in successful adult conversations. According to theoretical models of entrainment and research on motoric, cognitive, and social developmental milestones, the ability to entrain should develop throughout adolescence. However, little is known about the specific developmental trajectory or the role of speech entrainment in conversational outcomes of this age group. The purpose of this study is to characterize speech entrainment patterns in the conversations of neurotypical early adolescents. METHOD: This study utilized a corpus of 96 task-based conversations between adolescents between the ages of 9 and 14 years and a comparison corpus of 32 task-based conversations between adults. For each conversational turn, two speech entrainment scores were calculated for 429 acoustic features across rhythmic, articulatory, and phonatory dimensions. Predictive modeling was used to evaluate the degree of entrainment and relationship between entrainment and two metrics of conversational success. RESULTS: Speech entrainment increased throughout early adolescence but did not reach the level exhibited in conversations between adults. Additionally, speech entrainment was predictive of both conversational quality and conversational efficiency. Furthermore, models that included all acoustic features and both entrainment types performed better than models that only included individual acoustic feature sets or one type of entrainment. CONCLUSIONS: Our findings show that speech entrainment skills are largely developed during early adolescence with continued development possibly occurring across later adolescence. Additionally, results highlight the role of speech entrainment in successful conversation in this population, suggesting the import of continued exploration of this phenomenon in both neurotypical and neurodivergent adolescents. We also provide evidence of the value of using holistic measures that capture the multidimensionality of speech entrainment and provide a validated methodology for investigating entrainment across multiple acoustic features and entrainment types.

The Application of Time-Frequency Masking To Improve Intelligibility of Dysarthric Speech in Background Noise.

PURPOSE: Background noise reduces speech intelligibility. Time-frequency (T-F) masking is an established signal processing technique that improves intelligibility of neurotypical speech in background noise. Here, we investigated a novel application of T-F masking, assessing its potential to improve intelligibility of neurologically degraded speech in background noise. METHOD: Listener participants (N = 422) completed an intelligibility task either in the laboratory or online, listening to and transcribing audio recordings of neurotypical (control) and neurologically degraded (dysarthria) speech under three different processing types: speech in quiet (quiet), speech mixed with cafeteria noise (noise), and speech mixed with cafeteria noise and then subsequently processed by an ideal quantized mask (IQM) to remove the noise. RESULTS: We observed significant reductions in intelligibility of dysarthric speech, even at highly favorable signal-to-noise ratios (+11 to +23 dB) that did not impact neurotypical speech. We also observed significant intelligibility improvements from speech in noise to IQM-processed speech for both control and dysarthric speech across a wide range of noise levels. Furthermore, the overall benefit of IQM processing for dysarthric speech was comparable with that of the control speech in background noise, as was the intelligibility data collected in the laboratory versus online. CONCLUSIONS: This study demonstrates proof of concept, validating the application of T-F masks to a neurologically degraded speech signal. Given that intelligibility challenges greatly impact communication, and thus the lives of people with dysarthria and their communication partners, the development of clinical tools to enhance intelligibility in this clinical population is critical.

Functional near-infrared spectroscopy measures of neural activity in children with and without developmental language disorder during a working memory task.

INTRODUCTION: Children with developmental language disorder (DLD) exhibit cognitive deficits that interfere with their ability to learn language. Little is known about the functional neuroanatomical differences between children developing typically (TD) and children with DLD. METHODS: Using functional near-infrared spectroscopy, we recorded oxygenated hemoglobin (O2 hb) concentration values associated with neural activity in children with and without DLD during an auditory N-back task that included 0-back, 1-back, and 2-back conditions. Analyses focused on the left dorsolateral prefrontal cortex (DLPFC) and left inferior parietal lobule (IPL). Multilevel models were constructed with accuracy, response time, and O2 hb as outcome measures, with 0-back outcomes as fixed effects to control for sustained attention. RESULTS: Children with DLD were significantly less accurate than their TD peers at both the 1-back and 2-back tasks, and they demonstrated slower response times during 2-back. In addition, children in the TD group demonstrated significantly greater sensitivity to increased task difficulty, showing increased O2 hb to the IPL during 1-back and to the DLPFC during the 2-back, whereas the DLD group did not. A secondary analysis revealed that higher O2 hb in the DLPFC predicted better task accuracy across groups. CONCLUSION: When task difficulty increased, children with DLD failed to recruit the DLPFC for monitoring information and the IPL for processing information. Reduced memory capacity and reduced engagement likely contribute to the language learning difficulties of children with DLD.

Sexual Violence in Military Service Members/Veterans Individual and Interpersonal Outcomes Associated with Single and Multiple Exposures to Civilian and Military Sexual Violence.

Sexual harassment and violence is a grave public health concern and risk for revictimization increases following initial exposure. Studies of sexual revictimization in military samples are generally limited to women and are focused on rates of posttraumatic stress disorder (PTSD), with no examination of how revictimization relates to interpersonal outcomes, such as relationship or sexual satisfaction. The current study addressed these gaps in a sample of 833 women and 556 men service members/veterans. Self-reported outcomes of PTSD, depression, suicidal ideation, sexual function, and relationship satisfaction were compared across those reporting exposure to sexual harassment and violence before the military only (i.e., pre-military), during the military only (i.e., military sexual harassment and violence [MSV]), before and during the military (i.e., revictimization), and to no exposure. More than half of women (51.14%, n = 426) reported revictimization and only 5.79% (n = 28) of men reported revictimization. Among women, those reporting MSV or revictimization tended to report higher PTSD, depression, and suicidal ideation relative to pre-military sexual violence and no sexual violence exposure. No interpersonal outcomes were significantly different among these sexual violence groups. Among men, revictimization was associated with higher PTSD, depression, and sexual compulsivity. PTSD and depression were also higher among those reporting MSV only. No effects were found for premilitary sexual trauma exposure only or relationship satisfaction for either group. Findings highlight the particularly bothersome nature of MSV, whether it occurred alone or in tandem with premilitary sexual violence. Findings also show unique gender differences across outcomes, suggesting interventions following sexual harassment and violence may differ for men and women.

Moderators and predictors in a parent hearing aid management eHealth program.

OBJECTIVE: Consistent hearing aid use is essential for spoken language development of children who are hard of hearing. A recent randomised controlled trial of an eHealth hearing aid management education program found the intervention increased knowledge, perceptions, confidence, and device monitoring among parents of young children. Yet, it is not known which variables can be a point of emphasis to improve treatment outcomes. The purpose of this study was to investigate potential moderators and predictors in the eHealth program. DESIGN: Randomised controlled trial. STUDY SAMPLE: Parents (N = 78) of children (42 months or younger) were randomised to the intervention or treatment-as-usual (TAU) group. RESULTS: Results revealed that high psychological inflexibility, low parent activation, and low hours of hearing aid use may moderate device monitoring frequency and knowledge; parents in the intervention improved over time compared to the TAU group. Psychological inflexibility and parent activation also predicted treatment outcomes. CONCLUSION: The findings suggest the need to address parent psychological inflexibility related to hearing loss management, parents' role in their child's hearing aid management, and reported hours of hearing aid use as part of hearing aid service delivery. Identification of barriers to hearing aid management can assist audiologists in adjusting support to improve outcomes.

Step edge highlighters and illuminance changes influence stair descent in a real-world setting.

Studies investigating the effect of tread edge highlighters on descent speed differ, but collectively report the potential benefit of reduced fall risk. Here we examine the impact of adding high-contrast black vinyl striping to the front edge of each step's tread and its impact on descending gait speed (intervention), while controlling for illumination. Descending gait speed was estimated from 5,824 video observations using the stairway length and entry and exit times. A second stairway was unaltered (control) to compare to the intervention. Stair users were primarily 18-30 years old with a small percentage being middle-aged and older adults. Descending gait speed was significantly slower on the intervention stairway (Linear mixed effects model: standardised coefficient = -0.07, 95% CI = [-0.12, -0.02], p = .010) compared to the control and may be impacted by illuminance. We propose that the slowed gait speed could be due to changes in gait kinematics (e.g. foot clearance) and may reduce fall-risk. Practitioner summary: Tread-edge contrast enhancement could be a low-cost means to reduce fall-risk on stairways, but its impact on gait kinematics is not well understood. We found that contrast enhancement reduced descending gait speed, but descending gait speed's impact on fall risk reduction ultimately requires further investigation.

Posttraumatic Cognitions Differ Between Men and Women after Military Sexual Assault Revictimization in Their Contribution to PTSD Symptoms.

Sexual revictimization is heightened among military service members and veterans and is associated with greater posttraumatic stress symptoms (PTSS) and severity. The heightened distress following revictimization may be due to posttraumatic cognitions (PTC), which include negative beliefs about the self and world, and self-blame. Moreover, it is unclear whether men and women experience different levels of PTC. The current study tested PTC (overall and subdomains) as a possible mediator between sexual revictimization and PTSS severity, and gender as a possible moderator of these associations. Revictimization was defined across time periods (military sexual assault [MSA] only vs. premilitary sexual trauma + MSA) and in military rape frequency (0, 1, 2+). Participants were 400 (n = 200 [50%] male) service members/veterans with a history of MSA and completed online, anonymous, self-report questionnaires. PTC mediated the association between revictimization and PTSS severity. A significant interaction of gender suggested that men reported high overall PTC and PTC about the self regardless of revictimization; by contrast, overall PTC and PTC about the self were lower for women in response to MSA only and increased with revictimization. Results also showed men were more sensitive to PTC about self-blame as it pertains to more severe PTSS compared to women. There were no unique gender interactions when assessing revictimization by rape frequency, although PTC (overall, all subdomains) significantly mediated the association between rape frequency and PTSS severity. PTC may be a beneficial target when treating PTSS in men, and may be especially heightened in women who have experienced revictimization.

Cognitive Predictors of Perception and Adaptation to Dysarthric Speech in Young Adult Listeners.

PURPOSE: Although recruitment of cognitive-linguistic resources to support dysarthric speech perception and adaptation is presumed by theoretical accounts of effortful listening and supported by cross-disciplinary empirical findings, prospective relationships have received limited attention in the disordered speech literature. This study aimed to examine the predictive relationships between cognitive-linguistic parameters and intelligibility outcomes associated with familiarization with dysarthric speech in young adult listeners. METHOD: A cohort of 156 listener participants between the ages of 18 and 50 years completed a three-phase perceptual training protocol (pretest, training, and posttest) with one of three speakers with dysarthria. Additionally, listeners completed the National Institutes of Health Toolbox Cognition Battery to obtain measures of the following cognitive-linguistic constructs: working memory, inhibitory control of attention, cognitive flexibility, processing speed, and vocabulary knowledge. RESULTS: Elastic net regression models revealed that select cognitive-linguistic measures and their two-way interactions predicted both initial intelligibility and intelligibility improvement of dysarthric speech. While some consistency across models was shown, unique constellations of select cognitive factors and their interactions predicted initial intelligibility and intelligibility improvement of the three different speakers with dysarthria. CONCLUSIONS: Current findings extend empirical support for theoretical models of speech perception in adverse listening conditions to dysarthric speech signals. Although predictive relationships were complex, vocabulary knowledge, working memory, and cognitive flexibility often emerged as important variables across the models.

Values engagement as a predictor of eating disorder severity in a residential sample of female adolescents with eating disorders.

Values are freely chosen life directions and/or qualities of being that can motivate behavior change. There is nascent support for the utility of values work as a part of the therapeutic process across treatments, particularly in third wave therapy approaches (e.g., acceptance and commitment therapy). However, therapeutic values work is underresearched in clinical samples of youth. The aim of the present study is to examine the role of the two distinct values processes (engagement and obstruction), body image inflexibility, alongside other common comorbid symptoms of eating disorders (anxiety, depression) in a sample of female adolescents with eating disorders attending a residential eating disorder treatment program. Participants (N = 75) were patients at a residential eating disorder treatment facility and completed a battery of measures at time of admission. Correlational analyses and multiple regression were performed. Results found correlations between eating disorder severity, values engagement, values obstruction, body image flexibility, anxiety, and depression in the expected directions. Regression results found body image inflexibility, progression towards values, and anxiety as significant predictors of eating disorder severity (adjusted R2 = .54). This study points to the importance of emphasizing values engagement in youth with eating disorders, highlighting a potential treatment target for future research.

Acceptance and Action Questionnaire-Adult Hearing Loss (AAQ-AHL): validation with hearing aid users.

OBJECTIVE: Individuals who are deaf or hard of hearing (DHH) may find adherence to their hearing devices difficult due to internal experiences related to their hearing loss such as sadness or frustration. The Acceptance and Action Questionnaire-Adult Hearing Loss (AAQ-AHL) is the only measure available to assess psychological inflexibility as it relates to hearing loss. The purpose of this study was to confirm the single latent structure of the AAQ-AHL (through confirmatory factory analysis) and test convergent and discriminant validity. DESIGN: Cross-sectional data was used to further validate the AAQ-AHL. STUDY SAMPLE: Participants were 146 adults who had diagnosed hearing loss and used a hearing aid. RESULTS: Results revealed the AAQ-AHL has a single latent structure, correlated to other similar constructs (psychological flexibility and hearing aid efficacy), and not correlated to unrelated constructs (hearing loss severity). These results suggest that the AAQ-AHL is a valid instrument to assess psychological flexibility as it relates to hearing aid use. CONCLUSION: Together, the findings imply the AAQ-AHL has strong psychometric properties and justification to use in a clinical setting.

Supporting Emergent Bilinguals Who Use Augmentative and Alternative Communication and Their Families: Lessons in Telepractice From the COVID-19 Pandemic.

PURPOSE: The purpose of this project was to examine the effect of the COVID-19 pandemic on speech-language pathologist (SLP) service provision for emergent bilinguals who use augmentative and alternative communication (AAC). One prominent issue in AAC service delivery is the efficacy and feasibility of providing AAC services via telepractice. The COVID-19 pandemic intensified this issue as most providers, clients, and families adjusted to remote service delivery models. While emerging evidence supports telepractice in AAC, little is known about the potential benefits and challenges of telepractice for emergent bilinguals who use AAC and their families. METHOD: Data were collected via a nationwide survey. Licensed SLPs (N = 160) completed an online questionnaire with Likert-type, multiple-choice, and open-ended questions, analyzed using mixed methods. RESULTS: Findings illustrated a shift in service delivery from in-person to telepractice and hybrid (both telepractice and in-person) models. Overall, child intervention outcomes declined for emergent bilinguals who used AAC during the COVID-19 pandemic, regardless of service delivery format. However, collaboration increased for many providers and families. Qualitative analyses highlighted barriers to AAC service provision for emergent bilinguals who use AAC that were exacerbated by the COVID-19 pandemic, as well as factors that facilitated collaboration and family engagement. CONCLUSION: These findings suggest that, despite challenges, telepractice or hybrid services may be a promising approach to provide more culturally responsive, family-centered care for emergent bilinguals who use AAC.

Safe stairway negotiation: Role of distractions and handrail use.

INTRODUCTION: This study sought to examine stairway safety by identifying associations between fall-related events on stairways, distractions, gait speed, drifting, as well as handrail use and proximity. METHOD: Video recordings captured 11,137 observations of stair users in two public stairways and recorded distractions (e.g., looking at a mobile device, talking on a mobile device, using earbuds or headphones, holding a mobile device, or talking with a peer), gait speed (m/s), drifting (change of direction), as well as handrail use and proximity to a handrail. RESULTS: In our sample, consisting of primarily young adults (observed 18-40 years old), we found that when a distraction was present, gait speed was reduced (p <.001), drifting increased (p <.001), and handrail use negatively impacted (p <.001) compared to stair users who were not distracted. CONCLUSIONS: These results indicate that distractions, such as mobile devices, used during stair negotiation can reduce handrail use and increase behaviors associated with fall-related events. PRACTICAL APPLICATIONS: Mobile device use during stairway negotiation increases the likelihood of distraction-induced events. Stair users should be encouraged to limit or avoid mobile device use in public stairway environments. Mobile manufacturers and mobile app developers could aim to develop strategies or mobile app alerts to reduce the impact of distractions (e.g., mobile device use) during stair negotiation to lessen the health and financial burden associated with fall-related events on stairways.
