Look at Mummy: challenges in training parents to deliver a home treatment program for childhood apraxia of speech in a rural Canadian community

Introduction: Children requiring speech pathology services in rural and remote locations face many barriers in accessing adequate services. This has particular consequences for children who need intensive treatment for therapy to be effective, such those with childhood apraxia of speech (CAS). Parent training has been used to overcome speech pathology service delivery barriers for a range of other communication disorders. However, the effectiveness of training parents to deliver a motor-based treatment for CAS within rural and remote contexts has not been evaluated. This study examined the effectiveness and feasibility of training parents in a rural community to use the treatment approach of dynamic temporal and tactile cueing (DTTC) in order to provide more intensive treatment sessions at home. Methods: The study used an experimental single case across behaviours design and parent interviews to evaluate outcomes both quantitatively and qualitatively. The study included four parent- child dyads from a mixed socioeconomic rural community in Canada. Child participants ranged in age from 3 years to 8 years. Child treatment outcomes were measured using an improvement rate difference (IRD) calculation based on percentage of phonemes correct. Fidelity to the treatment protocol was measured using a fidelity score. Results: All parents reported challenges in carrying out the program due to social and behavioural challenges. Parents also reported benefits such as being able to spend more time with their child and learning some useful cueing techniques. Only one of the four participants had a moderate effect size for his target words (RD=57%). Conclusion: While training parents to deliver DTTC may be effective for some parent-child dyads, clinicians are advised that parent training may not be suitable for all families, and parents in rural and remote communities may face particular social circumstances that make following through with an intensive treatment program difficult

Long-Term Variability in Bioassessments: A Twenty-Year Study from Two Northern California Streams

Long-term variability of bioassessments has not been well evaluated. We analyzed a 20-year data set (1984–2003) from four sites in two northern California streams to examine the variability of bioassessment indices (two multivariate RIVPACS-type O/E scores and one multimetric index of biotic integrity, IBI), as well as eight metrics. All sites were sampled in spring; one site was also sampled in summer. Variability among years was high for most metrics (coefficients of variation, CVs ranging from 16% to 246% in spring) but lower for indices (CVs of 22–26% for the IBI and 21–32% for O/E scores in spring), which resulted in inconsistent assessments of biological condition. Variance components analysis showed that the time component explained variability in all metrics and indices, ranging from 5% to 35% of total variance explained. The site component was large (i.e., >40%) for some metrics (e.g., EPT richness), but nearly absent from others (e.g., Diptera richness). Seasonal analysis at one site showed that variability among seasons was small for some metrics or indices (e.g., Coleoptera richness), but large for others (e.g., EPT richness, O/E scores). Climatic variables did not show consistent trends across all metrics, although several were related to the El Niño Southern Oscillation Index at some sites. Bioassessments should incorporate temporal variability during index calibration or include climatic variability as predictive variables to improve accuracy and precision. In addition, these approaches may help managers anticipate alterations in reference streams caused by global climate change and high climatic variability

Watch vs do : a randomized crossover design evaluating modified simulated patients and video learning for novice speech-language therapy students

Background: Simulated learning activities are an effective tool for reducing speech–language therapy (SLT) students’ anxiety and improving their confidence for clinical placements. Such activities include interacting with patients who are actors, clinical educators or peers and are known to decrease anxiety and increase confidence in SLT students. Screen-simulated patients using video are another alternative, which has not yet been fully evaluated in the education of SLT students. Aims: To compare the effectiveness of (1) modified simulated patient and (2) video simulated learning for increasing self-reported (a) confidence and (b) preparedness and (c) decreasing self-reported anxiety. Methods & Procedures: This study used a randomized crossover design with 127 first-year graduate-entry master’s SLT student participants. Students participated in two activities related to a clinical interaction with a paediatric client’s carer: (1) a 1-hr modified simulated patient experience with clinical staff as the simulated patient; and (2) a video-learning task, with two videos of a clinician–carer interaction and an accompanying worksheet. Students were randomly allocated to a group of four students and the groups randomly allocated to receivemodified simulated patient or video-learning first. Students were not blinded to the activities. The students completed a 19-item questionnaire at three time points: before either activity, after the first activity and after the second activity, to evaluate their self-reported confidence, clinical preparedness and anxiety. Outcomes & Results: A total of 62 students completed modified simulated patient first and 63 completed video-learning first. After either single activity the students had significantly increased confidence and preparedness scores, while only the modified simulated patient significantly reduced student anxiety scores. As a second activity, modified simulated patient resulted in further significant improvements in confidence, preparedness and anxiety; however, adding video learning as a second activity resulted in no significant benefit. Conclusions & Implications: This study demonstrates the effectiveness of two low-resource clinical-learning activities for novice SLT students that can be applied in a range of settings. Of the two activities, modified simulated patient had greater effectiveness, as it was the only activity to decrease anxiety. An investigation of the pedagogical principles within the activities revealed that modified simulated patient activity had more opportunities for peer learning, supervisor feedback and verbal reflection in comparison with video learning that may explain the increased benefits

The adult perceptual limen of syllable segregation in typically developing paediatric speech

Inappropriate gaps between syllables are one of the core diagnostic features of both childhood apraxia of speech and acquired apraxia of speech. However, little is known about how listeners perceive and identify inappropriate pauses between syllables (gap detection). Only one previous study has investigated the perception of inappropriate pauses between syllables in typical adult speakers and no investigations of gap detection in children's speech have been undertaken. The purpose of this research was to explore the boundaries of listener gap detection to determine at which gap length (duration) a listener can perceive that an inappropriate pause is present in child speech. Listener perception of between-syllable gaps was explored in an experimental design study using the online survey platform Qualtrics. Speech samples were collected from two typically developing children and digitally manipulated to insert gaps between syllables. Adult listeners (n = 84) were recruited and could accurately detect segregation on 80% of presentations at a duration between 100 and 125 ms and could accurately detect segregation on 90% of presentations at a duration between 125 and 150 ms. Listener musical training, gender and age were not correlated with accuracy of detection, but speech pathology training was, albeit weakly. Male speaker gender, and strong onset syllable stress were correlated with increased accuracy compared to female speaker gender and weak onset syllable stress in some gap conditions. The results contribute to our understanding of speech acceptability in CAS and other prosodic disorders and moves towards developing standardised criteria for rating syllable segregation. There may also be implications for computer and artificial intelligence understanding of child speech and automatic detection of disordered speech based on between syllable segregation

'The early exposure is really helpful' : students' views of participating in communication skills screening

Students commence university with many hopes and dreams for their future and for most, these are realised. Health professional students must succeed in both their academic and clinical experiences. Excellent communication with their patients and colleagues on placement is necessary and particularly so for speech pathology students. This qualitative, descriptive study investigates how first- and final-year students view the screening of their communication skills in which they participate. The focus groups took place within the speech pathology department of a major Australian metropolitan university. Data were transcribed and analysed thematically. Three main themes arose: professional development, students’ cognitive and emotional responses, and the organisation of the screener. Both groups of students felt the screener was both an important part of their professional development and a way of identifying and supporting speech pathology students with communication difficulties. They valued the student-led nature of the process. Implications for the value of using a student-led communication screener to identify students with weaker communication skills early in their program and for the support of such students are discussed

A Brief Report on a Facilitated Approach to Connect Cooperative Extension Southern Region State-Level Health Specialists

Improving the nation’s health will require collaboration among many stakeholders and systems, including representatives from Cooperative Extension Services (CES). This paper describes the process of establishing a multistate collaboration and discusses initial outcomes of a third-party facilitated participatory planning meeting. State-level specialists with expertise and responsibilities in “health” promotion participated. Satisfaction with meeting format; feasibility, acceptability, and appropriateness of the proposed approach to public health impact; and general meeting feedback were collected through a survey and cultural artifacts (e.g., notes, worksheets). Preparation and attendance costs were captured. Seventeen of the 20 attendees (85%) responded to the survey and reported the process was satisfactory and the proposed plan for moving forward was feasible, acceptable, and appropriate. The meeting cost was $1,011 per attendee. The process mobilized a multistate Extension collaborative to promote health but revealed potential cost-benefit challenges. Leveraging resources is necessary to plan, implement, and measure collaborative public health efforts. Future data on outcomes will show if the process leads to intended objectives. If successful, this approach can be replicated across CES for stronger impacts

Acoustic voice characteristics with and without wearing a facemask

Facemasks are essential for healthcare workers but characteristics of the voice whilst wearing this personal protective equipment are not well understood. In the present study, we compared acoustic voice measures in recordings of sixteen adults producing standardised vocal tasks with and without wearing either a surgical mask or a KN95 mask. Data were analysed for mean spectral levels at 0–1 kHz and 1–8 kHz regions, an energy ratio between 0–1 and 1–8 kHz (LH1000), harmonics-to-noise ratio (HNR), smoothed cepstral peak prominence (CPPS), and vocal intensity. In connected speech there was significant attenuation of mean spectral level at 1–8 kHz region and there was no significant change in this measure at 0–1 kHz. Mean spectral levels of vowel did not change significantly in mask-wearing conditions. LH1000 for connected speech significantly increased whilst wearing either a surgical mask or KN95 mask but no significant change in this measure was found for vowel. HNR was higher in the mask-wearing conditions than the no-mask condition. CPPS and vocal intensity did not change in mask-wearing conditions. These findings implied an attenuation effects of wearing these types of masks on the voice spectra with surgical mask showing less impact than the KN95

The effectiveness of simple psychological and exercise interventions for high prevalence mental health problems in young people: a factorial randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>The prevalence of mental illness in young people is the highest of any age group, with the onset of depression, anxiety and substance use peaking between 18 and 24 years. Effective treatments that target sub-threshold or mild to moderate levels of disorder in young people are required to reduce the risk of persistence and recurrence. The aims of this study are to evaluate whether treatments that are less intensive than cognitive-behaviour therapy, such as problem solving therapy and exercise treatments, are acceptable and effective in managing depression and anxiety symptoms in young people and to identify possible attributes in those who are likely to respond to these treatments.</p> <p>Methods/design</p> <p>This is a factorial randomised controlled trial conducted at a large, metropolitan youth mental health service. Participants are young help-seekers aged 15-25 years with sub-threshold or mild to moderate levels of depression and anxiety (with or without comorbid substance use). The interventions comprise 4 treatment combinations delivered by psychologists over 6 sessions on a weekly basis: a psychological intervention (problem solving therapy versus supportive counselling) and an exercise intervention (behavioural exercise versus psychoeducation). Structured assessments occur at baseline, mid-point, end-point (6 weeks) and at a 6- and 12-month follow-up. The primary outcomes are depression and anxiety symptoms as measured by the Beck Depression and Anxiety Inventories. Secondary outcomes include remission (defined as no longer meeting the diagnostic criteria for a disorder if threshold level was reached at baseline, or no longer scoring in the clinical range on scale scores if sub-threshold at baseline), substance use, and functioning.</p> <p>Discussion</p> <p>The effectiveness of less complex psychological and exercise interventions in young help-seekers with sub-threshold or mild to moderate presentations of high prevalence disorders is yet to be explored. This study has been designed to examine the effectiveness of these interventions delivered alone, or in combination, in a youth-specific service. If effective, the interventions have the potential to prevent the progression of early symptoms and distress to later and potentially more serious stages of mental disorder and reduce the likelihood of ongoing problems associated with the risk of persistence and recurrence.</p> <p>Trial registration</p> <p>Australian New Zealand Clinical Trials Registry <a href="http://www.anzctr.org.au/ACTRN12608000550303.aspx">ACTRN12608000550303</a></p

Developmental risk among Aboriginal children living in urban areas in Australia : the Study of Environment on Aboriginal Resilience and Child Health (SEARCH)

Background: Most Australian Aboriginal children are on track with their development, however, the prevalence of children at risk of or with a developmental or behavioural problem is higher than in other children. Aboriginal child development data mostly comes from remote communities, whereas most Aboriginal children live in urban settings. We quantified the proportion of participating children at moderate and high developmental risk as identified by caregivers' concerns, and determined the factors associated with developmental risk among urban Aboriginal communities. Methods: Study methods were co-designed and implemented with four participating urban Aboriginal Community Controlled Health Services in New South Wales, Australia, between 2008 and 2012. Caregiver-reported data on children < 8 years old enrolled in a longitudinal cohort study (Study of Environment on Aboriginal Resilience and Child Health: SEARCH) were collected by interview. The Parents' Evaluation of Developmental Status (PEDS) was used to assess developmental risk through report of caregiver concerns. Odds ratios (OR) were calculated using multinomial logistic regression to investigate risk factors and develop a risk prediction model. Results: Of 725 children in SEARCH with PEDS data (69% of eligible), 405 (56%) were male, and 336 (46%) were aged between 4.5 and 8 years. Using PEDS, 32% were at high, 28% moderate, and 40% low/no developmental risk. Compared with low/no risk, factors associated with high developmental risk in a mutually-adjusted model, with additional adjustment for study site, were male sex (OR 2.42, 95% confidence intervals 1.62-3.61), being older (4.5 to < 8 years versus < 3 years old, 3.80, 2.21-6.54), prior history of ear infection (1.95, 1.21-3.15), having lived in 4 or more houses versus one house (4.13, 2.04-8.35), foster care versus living with a parent (5.45, 2.32-12.78), and having a caregiver with psychological distress (2.40, 1.37-4.20). Conclusion: In SEARCH, 40% of urban Aboriginal children younger than 8 years were at no or low developmental risk. Several factors associated with higher developmental risk were modifiable. Aboriginal community-driven programs to improve detection of developmental problems and facilitate early intervention are needed
