Guideline adherence in speech and language therapy in stroke aftercare. A health insurance claims data analysis.

BACKGROUND: Impairments to comprehension and production of speech (aphasia, dysarthria) and swallowing disorders (dysphagia) are common sequelae of stroke, reducing patients' quality of life and social participation. Treatment oriented on evidence-based guidelines seems likely to improve outcomes. Currently, little is known about guideline adherence in stroke aftercare for the above-mentioned sequelae. This study aims to analyse guideline adherence in the treatment of aphasia, dysarthria and dysphagia after stroke, based on suitable test parameters, and to determine factors that influence the implementation of recommended therapies. METHODS: Six test parameters were defined, based on systematic study of guidelines for the treatment of speech impairments and swallowing disorders (e.g. comprehensive diagnostics, early initiation and continuity). Guideline adherence in treatment was tested using claims data from four statutory health insurance companies. Multivariate logistic and linear regression analyses were performed in order to test the outcomes. RESULTS: 4,486 stroke patients who were diagnosed with specific disorders or received speech therapy were included in the study. The median age was 78 years; the proportion of women was 55.9%. Within the first year after the stroke, 90.3% of patients were diagnosed with speech impairments and swallowing disorders. Overall, 44.1% of patients received outpatient speech and language therapy aftercare. Women were less frequently diagnosed with specific disorders (OR 0.70 [95%CI:0.55/0.88], p = 0.003) and less frequently received longer therapy sessions (OR 0.64 [95%CI:0.43/0.94], p = 0.022). Older age and longer hospitalization duration increased the likelihood of guideline recommendations being implemented and of earlier initiation of stroke aftercare measures. CONCLUSIONS: Our observations indicate deficits in the implementation of guideline recommendations in stroke aftercare. At the same time, they underscore the need for regular monitoring of implementation measures in stroke aftercare to address group-based disparities in care.

A Consensus Statement for the Management and Rehabilitation of Communication and Swallowing Function in the ICU: A Global Response to COVID-19.

OBJECTIVE: To identify core practices for workforce management of communication and swallowing functions in coronavirus disease 2019 (COVID-19) positive patients within the intensive care unit (ICU). DESIGN: A modified Delphi methodology was used, with 3 electronic voting rounds. AGREE II and an adapted COVID-19 survey framework from physiotherapy were used to develop survey statements. Sixty-six statements pertaining to workforce planning and management of communication and swallowing function in the ICU were included. SETTING: Electronic modified Delphi process. PARTICIPANTS: Speech-language pathologists (SLPs) (N=35) from 6 continents representing 12 countries. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The main outcome was consensus agreement, defined a priori as ≥70% of participants with a mean Likert score ≥7.0 (11-point scale: 0=strongly disagree, 10=strongly agree). Prioritization rank order of statements in a fourth round was also conducted. RESULTS: SLPs with a median of 15 years of ICU experience, working primarily in clinical (54%), academic (29%), or managerial positions (17%), completed all voting rounds. After the third round, 64 statements (97%) met criteria. Rank ordering identified issues of high importance. CONCLUSIONS: A set of global consensus statements to facilitate planning and delivery of rehabilitative care for patients admitted to the ICU during the COVID-19 pandemic were agreed by an international expert SLP group. Statements focused on considerations for workforce preparation, resourcing and training, and the management of communication and swallowing functions. These statements support and provide direction for all members of the rehabilitation team to use for patients admitted to the ICU during a global pandemic.

Treatment Fidelity Procedures for an Aphasia Intervention Within a Randomized Controlled Trial: Design, Feasibility, and Results.

Purpose This study reports on the treatment fidelity procedures implemented during a 5-year randomized controlled trial comparing intensive and distributed comprehensive aphasia therapy. Specifically, the results of 1 treatment, verb network strengthening treatment (VNeST), are examined. Method Eight participants were recruited for each of 7 consecutive cohorts for a total of 56 participants. Participants completed 60 hr of aphasia therapy, including 15 hr of VNeST. Two experienced speech-language pathologists delivered the treatment. To promote treatment fidelity, the study team developed a detailed manual of procedures and fidelity checklists, completed role plays to standardize treatment administration, and video-recorded all treatment sessions for review. To assess protocol adherence during treatment delivery, trained research assistants not involved in the treatment reviewed video recordings of a subset of randomly selected VNeST treatment sessions and completed the fidelity checklists. This process was completed for 32 participants representing 2 early cohorts and 2 later cohorts, which allowed for measurement of protocol adherence over time. Percent accuracy of protocol adherence was calculated across clinicians, cohorts, and study condition (intensive vs. distributed therapy). Results The fidelity procedures were sufficient to promote and verify a high level of adherence to the treatment protocol across clinicians, cohorts, and study condition. Conclusion Treatment fidelity strategies and monitoring are feasible when incorporated into the study design. Treatment fidelity monitoring should be completed at regular intervals during the course of a study to ensure that high levels of protocol adherence are maintained over time and across conditions.

Stuttering: Understanding and Treating a Common Disability.

Childhood-onset fluency disorder, the most common form of stuttering, is a neurologic disability resulting from an underlying brain abnormality that causes disfluent speech. Stuttering can lead to significant secondary effects, including negative self-perception and negative perception by others, anxiety, and occasionally depression. Childhood-onset fluency disorder affects 5% to 10% of preschoolers. Early identification of stuttering is important so that therapy can begin while compensatory changes to the brain can still occur and to minimize the chances of the patient developing social anxiety, impaired social skills, maladaptive compensatory behaviors, and negative attitudes toward communication. However, stuttering may be persistent, even with early intervention, and affects about 1% of adults. In patients with persistent stuttering, speech therapy focuses on developing effective compensatory techniques and eliminating ineffective secondary behaviors. The role of family physicians includes facilitating early identification of children who stutter, arranging appropriate speech therapy, and providing support and therapy for patients experiencing psychosocial effects from stuttering. Finally, physicians can serve as advocates by making the clinic setting more comfortable for people who stutter and by educating teachers, coaches, employers, and others in the patient's life about the etiology of stuttering and the specific challenges patients face.

Cross-Cultural Adaptation of the Scale of Auditory Behaviors Questionnaire.

Purpose Children with (central) auditory processing disorder [(C)APD] exhibit many cognitive difficulties and receive negative psychosocial consequences from their disorder. Diagnosis of (C)APD relies on multidisciplinary assessment, including psychological testing. There is a strong need for valid and reliable questionnaires to identify children who are at risk of (C)APD. This work aims to establish the psychometric properties of the Polish version of the Scale of Auditory Behaviors (SAB; Domitz & Schow, 2000; Krzeszewska & Kurkowski, 2015; Miranda, Bruera, & Serra 2016; Musiek & Chermak, 2007; Nunes et al., 2013) as a screening tool in children. Method The SAB was administered to parents of 326 children (152 girls and 174 boys) aged from 6 to 12 years (M = 8.24, SD = 1.56). The questionnaire consists of 12 items related to various symptoms of (C)APD and allows the frequency of particular behaviors to be assessed. In addition, the questionnaire Children's Home Inventory for Listening Difficulties was administered to parents, and 3 other psychoacoustic behavioral tests (Frequency Pattern Test, Duration Pattern Test, Dichotic Digit Test; Czajka et al., 2012) were conducted on the children to evaluate their auditory abilities. Results The Polish version of SAB demonstrated high internal consistency (Cronbach's α = .93), confirmed by interitem correlations. Intraclass correlation, which was used to determine reproducibility, was .95. There were also significant and positive relationships, ranging from r = .17 to .68, between the SAB score and scores of other measures, indicating convergent validity of the tool. Girls demonstrated higher SAB scores than boys (p < .05); however, age was not statistically significant. A ceiling effect was detected, but no floor effect. Conclusions Results of psychometric and statistical analyses suggest the Polish version of SAB appears to be a valid and reliable questionnaire to evaluate symptoms of (C)APD in children, especially as a screening tool.

Concurrent Validity of the Fluharty Preschool Speech and Language Screening Test-Second Edition at Age 3: Comparison With Four Diagnostic Measures.

Purpose The aim of this study was to examine the concurrent validity of the Fluharty Preschool Speech and Language Screening Test-Second Edition (Fluharty-2; Fluharty, 2001) for mass screenings of language at age 3 years. Method Participants were sixty-two 3-year-old children, 31 who had failed and 31 who had passed the Fluharty-2. Performance on the screening was compared to 4 diagnostic measures: Structured Photographic Expressive Language Test-Preschool, Second Edition; mean length of utterance in morphemes (MLUm), finite verb morphology composite, and Index of Productive Syntax (IPSyn). Results Children who failed the Fluharty-2 scored significantly lower on each of the diagnostic measures than children who passed the Fluharty-2, but the effect size for MLUm was small. Scores on the Fluharty-2 were significantly correlated with scores on the diagnostic measures. There was significant agreement for pass/fail decisions between the Fluharty-2 and diagnostic measures only for IPSyn. However, even for the IPSyn, the agreement rate for passing was only moderate (80%) and the agreement rate for failing was only fair (68%). Conclusion The Fluharty-2 showed limited agreement for pass/fail decisions with all 4 of the diagnostic measures. There was reason to question the validity of 2 of the diagnostic measures-Structured Photographic Expressive Language Test-Preschool, Second Edition and MLUm-for diagnosing language impairment in 3-year-old children. However, there were no such concerns about finite verb morphology composite or IPSyn to account for the limited agreement. Thus, it seems reasonable to conclude that the Fluharty-2 would refer both too few at-risk children and too many nonrisk children for a follow-up assessment, making it an inefficient tool for mass screenings of language.

Speech and language therapy best practice for patients in prolonged disorders of consciousness: a modified Delphi study.

BACKGROUND: Research regarding speech and language therapy (SLT) for patients in prolonged disorders of consciousness (PDOC) is very limited. The Royal College of Physicians' (RCP) PDOC guideline provides recommendations regarding best practice, but does not give detail about many aspects of assessment and management. As a result, SLTs have little information regarding best practice for this complex patient group. AIMS: To ascertain the degree of consensus amongst expert SLTs regarding SLT best practice for patients in PDOC in order to inform the future development of SLT guidelines. METHODS & PROCEDURES: A two-round modified Delphi technique was used. Participants were recruited from major trauma centres and neurorehabilitation units in England and national SLT clinical excellence networks. To participate, SLTs had to be working on neurosciences, neurosurgery or neurorehabilitation wards that treat adult PDOC patients, or have ≥ 3 years' experience of working with PDOC. The Round 1 questionnaire was developed from the RCP's PDOC guideline and from existing research literature. It included ratings of statements regarding SLT best practice using Likert or temporal scales, with optional written justifications/comments and opportunities for participants to suggest additional statements. The percentage agreement amongst participants was calculated for each Round 1 statement. Written justifications for views were analysed using content analysis. The Round 2 questionnaire contained both quantitative and qualitative feedback from Round 1, allowing participants to reappraise their views. The final degree of consensus was then calculated after completion of both rounds. OUTCOMES & RESULTS: A total of 40 SLTs completed Round 1, with 36 completing Round 2 (90% response rate). Consensus was achieved for 87% (67/77) of statements regarding best practice on a variety of topics including communication, tracheostomy, dysphagia and oral hypersensitivity. The statements represented assessment, management and service delivery components of SLT practice. CONCLUSIONS & IMPLICATIONS: A total of 67 best practice statements were created. The statements provide a useful starting point for the creation of SLT guidelines to support best practice, and also have the potential to be used to advocate for the provision of SLT services for patients in PDOC. Future studies should focus on whether the expert opinion generated here can be borne out in experimental research.

Speech-Language Clinicians Working with Deaf Children: A Qualitative Study in Context.

Students who are deaf or hard of hearing (DHH) increasingly attend local public schools, in which speech and language clinicians (SLCs) may lack experience with the individualized needs of a heterogeneous student population. This study explored the experiences of SLCs with students who are DHH in three different types of educational settings. Fourteen SLCs were interviewed and discussed a case study. Responses were transcribed, data coded, and emergent themes identified. Analysis was verified through triangulation of data and trustworthiness strategies. Results indicated that the skill sets of SLCs working with children who were DHH were dependent on contextual factors, such as educational placement and communication mode used, and that development of these skills requires direct experience, collaboration, and structural supports. Institutions across the deaf education spectrum should consider forming alliances to improve information-sharing and collaborative learning in order to improve service delivery in all settings.

Engaging multiple stakeholders to improve speech and language therapy services in schools: an appreciative inquiry-based study.

BACKGROUND: Effective collaboration between speech and language therapists (SLTs) and teachers is essential in meeting the needs of children with developmental language disorders in school, but it is difficult to achieve. Currently, many children receive inadequate speech and language therapy services and/or support in school. The aim of this study was to engage key stakeholders (SLTs, teachers, parents and children with DLD) in the co-design of their ideal speech and language therapy service and support in school. The study was undertaken in order to inform the development of a conceptual model to guide collaborative practice when working with this population. METHODS: A qualitative study involving a diverse range of key stakeholders and using appreciative inquiry. This is a method which enables those involved to construct their 'ideal' about a topic of interest. Recruitment was carried out using purposive sampling. We conducted focus groups with practitioners (SLTs and teachers) and parents as well as semi-structured interviews with children who have DLD using 'draw and tell' techniques. A total of five focus groups and nine interviews were conducted with participants (n = 27). RESULTS: The children described their ideal supports as those which enabled them to connect, contribute and achieve. They describe ways in which environmental barriers in school needed to be addressed to allow them to do so. The professionals primarily described ways in which the language skills of the child could be improved. Both parents and practitioner groups described the importance of strengthening networks between service providers and service users. They also highlighted the need to promote a collaborative culture if stakeholders are to work effectively together across sectors. CONCLUSIONS: There were differences in perspectives about the ways in which speech and language therapy services and supports could be improved, demonstrating the importance of engaging a diverse group of stakeholders. Of note were the unique insights the children brought about the barriers they faced as a result of their difficulties. Based on our findings we propose that children should be given influence in decisions about the supports that they receive in school. Implications for policy, research and practice are discussed.

[What speech therapists, occupational therapists and physical therapist need to know to become evidence-based practitioners: A cross-sectional study]. / Lernbedarf von PraktikerInnen der Logopädie, Ergotherapie und Physiotherapie für evidenzbasiertes Arbeiten - Querschnittsstudie.

BACKGROUND: Today we are faced with changes in society and healthcare needs resulting from demographic transition. Among many other developments, the increasing complexity of healthcare creates new requirements for health professionals. To meet these requirements, such as evidence-based practice, professionally experienced therapists need additional training courses to acquire scientific competencies in addition to their professional competence. Certification courses for practitioners in the fields of speech therapy, occupational therapy and physical therapy offer a way to achieve these scientific competencies. AIM: The aim of this study was to gather empirical data that help to develop scientific contents for additional training courses on a higher education level. These contents must fit the learning needs of the target group with regard to evidence-based practice. METHODS: In a multi-method approach a questionnaire was created consisting of four parts. These contained closed questions on self-assessed learning needs for competencies in evidence-based practice with and without links to therapeutic practice, open questions about the design of a certification course as well as socio-demographic questions. The results were shown using frequencies and correlations between learning, work experience and level of education. Contextual correlations were calculated using Kendall's tau correlation of Cramer's V, a contingency coefficient based on Chi square. Answers to the open questions were assigned to subcategories. RESULTS: The answers of 70 therapists (11,5 % speech therapist, 17,1 % occupational therapists, 70 % physical therapists, 1,4 % unspecified) were evaluated. The results demonstrate that there are high learning needs (> 80 %) of the total sample regarding content of assessments and test procedures, evidence-based practice as well as clinical decision-making and interprofessional cooperation. The therapists see a high demand for additional skills combined with scientific knowledge and their own professional experience (92,8 %). Almost 90 % identified high learning requirements for the skill of critically reflecting on the treatments they provided. Depending on prior professional experience, learning needs differed for evidence-based practice with and without links to therapeutic practice. As to the design of certification courses, the participants preferred low costs, a flexible time-structure as well as teaching methods making the input more vivid and comprehensible. DISCUSSION: Scientific qualification of healthcare practitioners must address the learning requirements for evidence-based practice. For this purpose, teaching of scientific work skills such as scientific writing, evidence-based practice and quantitative and qualitative methods is recommended. The fact that the questionnaire has not been validated may limit the validity of the results. Due to the indirect distribution of the questionnaires, the survey may have been liable to non-response bias.

Barriers and facilitators to meeting aphasia guideline recommendations: what factors influence speech pathologists' practice?

PURPOSE: To explore factors influencing Australian speech pathologists' guideline recommended aphasia management practices. METHODS: Semi-structured interviews were conducted with hospital-based speech pathologists (n = 20). Interviews focused on barriers and facilitators to implementing recommendations related to five practice areas: Aphasia-friendly Information; Collaborative Goal Setting; Timing of Therapy; Amount and Intensity of Therapy; and Conversation Partner Training. RESULTS: Speech pathologists working only in inpatient rehabilitation settings reported performing the recommended behaviours consistently, and identified few implementation barriers. However, clinicians working in the acute setting reported performing the majority of behaviours inconsistently or rarely. Seven (of 14) Theoretical Domains Framework domains were identified as key influencing factors. Three of these - "Environmental Context and Resources," "Beliefs about Consequences," and "Social Influences" - were consistently reported as influencing practice across all five behaviours. Other important domains included "Knowledge", "Beliefs about Capabilities," "Goals," and "Social/Professional Role and Identity", which each influenced at least two practice behaviours. CONCLUSIONS: Speech pathologists report a number of key factors influencing their practice, which differ in how they influence behaviours (i.e., a factor may be a barrier or a facilitator) depending on the behaviour and clinical setting. Future implementation interventions need to account for the strong influence of beliefs and social influences on speech pathology practice, which may facilitate successful implementation. Implications for rehabilitation Speech pathologists' aphasia management practices are often inconsistent with guideline recommendations. Environmental and contextual barriers were identified for all guideline-recommended practices that were investigated; however, these barriers did not necessarily impede implementation for speech pathologists working in inpatient rehabilitation settings. Strategies to improve both team functioning (social influences) and the belief systems of individual clinicians (beliefs about consequences) should be considered to improve speech pathologists' implementation of guideline-recommended aphasia practices.

Brazilian scale of hearing and language development: normality curve for infants and children from 0 to 24 months old with normal hearing

Introduction: Cochlear implants are currently the most effective technological resource to facilitate access to the hearing world for deaf people. Their use, especially when implanted early in children, reduces the impact of deafness on hearing as well as on the development of spoken language. Objective: To validate the first part of the Brazilian Scale of Hearing and Language Development (EDAL-1, in the Portuguese acronym) and to establish the normal curve in infants and children aged between 0 and 24 months old with normal hearing. Method: This is an experimental study of a descriptive nature, conducted with 92 infants and children with normal hearing. Every infant/child was evaluated audiologically, and the EDAL-1 was applied to their parents. The responses were categorized by applying the EDAL-1 every 3 months for each child. Results: The EDAL-1 was shown to be easily applied by the researcher and easily understood by the parents. It was possible to classify the sample every 3 months and describe the results. The average of the responses found in terms of scores for each age category shows an increasing scale following the evolution of the chronological age: 3 months-34.23 points; 6 months-54.68 points; 9 months-73 points; 12 months- 82.5 points; 15 months-87 points; 18 months-91 points; 21 months-92.5 points, and 24 months-95.83 points. Conclusion: The normal curve for EDAL-1 was successfully established. The averages can be considered as the standard protocol for normality, serving as a reference for comparison with other populations (AU)

Measuring and Training Speech-Language Pathologists' Orofacial Cueing: A Pilot Demonstration.

Tactile-kinesthetic-proprioceptive (TKP) input used to facilitate speech motor control is considered an active ingredient within speech motor interventions. Objective metrics identifying skill level differences across speech-language pathologists (S-LP) providing TKP cues are crucial for monitoring treatment delivery fidelity. The study examined three kinematic measures indicating accuracy and consistency of TKP inputs by 3 S-LPs with varying experience levels (S-LP 1: novice; S-LP 2 and S-LP 3: advanced). Confidence interval measures were used to compare the accuracy of jaw movement amplitudes of the vowel /a/ made by a model participant versus S-LPs giving the TKP input. Generalised Orthogonal Procrustes Analysis (GPA) and cyclic Spatial Temporal Index (cSTI) were used to determine movement consistency. Results revealed passive jaw excursions induced by S-LP 2 and 3 to be not statistically significant from the model participant's active jaw movements. cSTI values decreased with advanced level of experience (19.28, 12.14, and 9.33 for S-LP 1, S-LP 2, and S-LP 3, respectively). GPA analyses revealed a similar pattern for S-LPs with more experience demonstrating lower mean RMS values (0.22, 0.03, and 0.11 for S-LP 1, S-LP 2, and S-LP 3, respectively). Findings suggest kinematic measures adapted from the motor control literature can be applied to assess S-LP skill differences in providing TKP cues.

Parent experiences of variations in service delivery of Rapid Syllable Transition (ReST) treatment for childhood apraxia of speech.

PURPOSE: To understand parents' perceptions of Rapid Syllable Transition (ReST) treatment and their experience of either telehealth or combined parent-clinician delivery of speech-language pathology. METHOD: Thematic analyses of semi-structured interviews were conducted with 10 parents (5 telehealth, 5 parent-clinician) after their child completed 12 sessions of ReST treatment. RESULTS: Three themes were unique to telehealth: "telehealth was a million times easier," "technical problems weren't deal breakers," and "telehealth therapy has different boundaries." Three themes were unique to parent-clinician delivery: "therapy is something to get over and done with," "I wasn't very good at doing therapy," and "my child doesn't like me as his therapist." Both groups had themes related to the significance of childhood apraxia of speech, the importance of specialist treatment, and ReST being a "different way forward." CONCLUSIONS: Speech-language pathologists should carefully consider the suitability of caregiver-provided ReST treatment, and increase telehealth delivery of ReST treatment.

Professional expertise amongst speech-language therapists: "willing to share".

Purpose The current healthcare environment provides several challenges to the existing roles of healthcare professionals. The value of the professional expert is also under scrutiny. The purpose of this paper is to generate a construction of professional expertise amongst practitioners in the current healthcare environment. It used the speech-language therapy community in New Zealand (NZ) as an example. Design/methodology/approach Speech-language therapists currently practicing in NZ completed an online survey including qualitative and quantitative components. The range of experience and work settings of participants ( n=119) was representative of the workforce. Findings Participants clearly identified being "highly experienced" and "having in-depth knowledge" as essential elements of professional expertise. Thematic analysis generated two interconnected themes of a professional expert being a personal leader and teacher, and a highly experienced, knowledgeable and skilful practitioner. Additionally, practitioners needed to be seen to contribute to the community in order to be known as experts. Clinical practice was valued differently from research generation. Originality/value This study is novel in exploring a construction of professional expertise amongst practitioners in a current healthcare community. Within that community, experts could be viewed as highly effective practitioners that visibly contribute to the professional community. The study draws attention to the role of reputation and the impacts of being a clinical teacher or leader compared with pursuing a research role. This could be particularly relevant in the promotion of evidence-based practice.

Survey of ENT services in sub-Saharan Africa: little progress between 2009 and 2015.

BACKGROUND: A 2009 survey of ENT, audiology, and speech therapy services and training opportunities in 18 Sub-Saharan African countries reported that the availability of services was extremely poor, the distribution of services was very inequitable, and training opportunities were limited. ​​Objective: We conducted a new survey to determine the current status of ear, nose, and throat (ENT), audiology, and speech therapy services in sub-Saharan Africa. METHOD: This study is a cross-sectional study. A questionnaire was distributed by email to an ad hoc group of ENT surgeons and audiologists in 30 sub-Saharan African countries. Data from the current survey were compared to those of a 2009 survey. The numbers of ENT surgeons, audiologists, and speech therapists/100,000 people were compared to the ratios in the United Kingdom. RESULTS: A total of 22 countries responded to the questionnaire. When data of the 15 countries that responded in both 2009 and 2015 are compared, the number of ENT surgeons had increased by 43%, audiologists had increased by 2.5%, and speech therapists by 30%. When the 23% population growth is taken into account, the numbers of ENT surgeons, audiologists, and speech therapists per 100,000 people had declined in four countries, and there remains a severe shortfall of ENT surgeons, audiologists, and speech therapists when compared to the UK Respondents cited lack of availability of basic equipment as the most frequent limitation in providing ENT services. Other important factors causing limitations in daily practice were: lack of ENT training facilities and audiological rehabilitation, low awareness of the burden of ENT pathology, as well as poor human resources management. CONCLUSIONS: There has been a lack of progress in ENT, audiology, and speech therapy services and training opportunities in sub-Saharan Africa between 2009 and 2015. There is a need to look at increased collaboration with developed countries and non-governmental organisations, establishing new and improving existing training centres in Africa, and task-shifting of some ENT services to primary health workers.

Implementation fidelity of a computer-assisted intervention for children with speech sound disorders.

BACKGROUND: Implementation fidelity refers to the degree to which an intervention or programme adheres to its original design. This paper examines implementation fidelity in the Sound Start Study, a clustered randomised controlled trial of computer-assisted support for children with speech sound disorders (SSD). METHOD: Sixty-three children with SSD in 19 early childhood centres received computer-assisted support (Phoneme Factory Sound Sorter [PFSS] - Australian version). Educators facilitated the delivery of PFSS targeting phonological error patterns identified by a speech-language pathologist. Implementation data were gathered via (1) the computer software, which recorded when and how much intervention was completed over 9 weeks; (2) educators' records of practice sessions; and (3) scoring of fidelity (intervention procedure, competence and quality of delivery) from videos of intervention sessions. RESULT: Less than one-third of children received the prescribed number of days of intervention, while approximately one-half participated in the prescribed number of intervention plays. Computer data differed from educators' data for total number of days and plays in which children participated; the degree of match was lower as data became more specific. Fidelity to intervention procedures, competency and quality of delivery was high. CONCLUSION: Implementation fidelity may impact intervention outcomes and so needs to be measured in intervention research; however, the way in which it is measured may impact on data.

The diagnostic utility of patient-report and speech-language pathologists' ratings for detecting the early onset of bulbar symptoms due to ALS.

OBJECTIVE: This study aimed to determine the diagnostic utility of clinician speech ratings and patient self-report for detecting early bulbar changes associated with amyotrophic lateral sclerosis (ALS), compared to instrumentation-based speech measures. METHODS: Thirty-six individuals with ALS and 17 healthy control participants were included. Patients' awareness of early bulbar motor involvement was assessed using self-reported scores on the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Clinicians' detection of early bulbar motor involvement was assessed through perceptual speech ratings by two experienced speech-language pathologists. Participants with ALS were grouped as 'bulbar pre-symptomatic' or 'bulbar symptomatic' based on self-report and clinician ratings, and compared to healthy controls on six instrumentation-based speech measures. ROC analysis was used to compare the sensitivity and specificity of perceptual and instrumentation-based measures for detecting bulbar changes in pre-symptomatic individuals. RESULTS: Early bulbar changes that were documented using instrumentation-based measures were undetected by both patients and clinicians. ROC analyses indicated that instrumentation-based measures outperformed clinicians' scaled severity ratings, and that percent pause time was the best measure for differentiating healthy controls from bulbar pre-symptomatic individuals with ALS. CONCLUSIONS: Findings suggested that instrumentation-based measures of speech may be necessary for early detection of bulbar changes due to ALS.

Treatment integrity of elaborated semantic feature analysis aphasia therapy delivered in individual and group settings.

BACKGROUND & AIMS: This study ran within the framework of the Thales Aphasia Project that investigated the efficacy of elaborated semantic feature analysis (ESFA). We evaluated the treatment integrity (TI) of ESFA, i.e., the degree to which therapists implemented treatment as intended by the treatment protocol, in two different formats: individual and group therapy. METHODS & PROCEDURES: Based on the ESFA manual, observation of therapy videos and TI literature, we developed two ESFA integrity checklists, for individual and group therapy, and used them to rate 15 videos of therapy sessions, delivered by three speech-language therapists (SLTs). Thirteen people with aphasia (PwA) were involved in this study. Reliability of the checklists was checked using Kappa statistics. Each session's TI was calculated. Differences in TI scores between the two therapy approaches were calculated using independent sample t-tests. Treating SLTs' views on what facilitates TI were also explored through a survey. OUTCOMES & RESULTS: Inter- and intra-rater reliability were excellent (.75 ≤ κ ≤ 1.00) for all but one video (κ = .63). Overall, a high TI level (91.4%) was achieved. Although both approaches' TI was high, TI for individual therapy sessions was significantly higher than for group sessions (94.6% and 86.7% respectively), t(13) = 2.68, p = .019. SLTs found training, use of the treatment manual, supervision and peer support useful in implementing ESFA therapy accurately. CONCLUSIONS & IMPLICATIONS: ESFA therapy as delivered in Thales is well described and therapists can implement it as intended. The high TI scores found enhance the internal validity of the main research project and facilitate its replication. The need for more emphasis on the methodological quality of TI studies is discussed.
