Abstract
PURPOSE This study examines the accuracy of Interaction Detection in Early Childhood Settings (IDEAS), a program that automatically transcribes audio files and estimates linguistic units relevant to speech-language therapy, including part-of-speech units that represent features of language complexity, such as adjectives and coordinating conjunctions. METHOD Forty-five video-recorded speech-language therapy sessions involving 27 speech-language pathologists (SLPs) and 56 children were used. The F measure determines the accuracy of IDEAS diarization (i.e., speech segmentation and speaker classification). Two additional evaluation metrics, namely, median absolute relative error and correlation, indicate the accuracy of IDEAS for the estimation of linguistic units as compared with two conditions, namely, Oracle (manual diarization) and Voice Type Classifier (existing diarizer with acceptable accuracy). RESULTS The high F measure for SLP talk data suggests high accuracy of IDEAS diarization for SLP talk but less so for child talk. These differences are reflected in the accuracy of IDEAS linguistic unit estimates. IDEAS median absolute relative error and correlation values for nine of the 10 SLP linguistic unit estimates meet the accuracy criteria, but none of the child linguistic unit estimates meet these criteria. The type of linguistic units also affects IDEAS accuracy. CONCLUSIONS IDEAS was tailored to educational settings to automatically convert audio recordings into text and to provide linguistic unit estimates in speech-language therapy sessions and classroom settings. Although not perfect, IDEAS is reliable in automatically capturing and returning linguistic units, especially in SLP talk, that are relevant in research and practice. The tool offers a way to automatically measure SLP talk in clinical settings, which will support research seeking to understand how SLP talk influences children's language growth.

Abstract
BACKGROUND Few studies have explored the feasibility of online language interventions for young children with Down syndrome. Additionally, none have manipulated dose frequency or reported on the use of music as a medium through which language and sign can be learned. PURPOSE The purpose of this study was to (a) examine the feasibility and acceptability of an online language through music intervention for young children (1-3;6 years) with Down syndrome and (b) compare effectiveness at two intervention dose frequencies. METHOD The study was carried out in two phases using a mixed-methods design. Phase 1: Qualitative data were gathered from parents to examine feasibility when implementing a video-based language intervention. Phase 2: Seventy-six families participated in an online language intervention at home. Effectiveness was examined comparing two groups, randomly assigned to a high and low dose frequency. The Down Syndrome Education (DSE) checklists (combined) were the primary outcome measure. Process data were gathered to determine intervention acceptability in practice and to identify factors that would improve successful future implementation. Acceptability data were analyzed with reference to the theoretical framework of acceptability (Version 2). RESULTS Forty-three parents completed the Phase 1 scoping questionnaire, five of whom took part in focus groups. Once weekly morning sessions were indicated as the preferred scheduling choice. Phase 2 quantitative data were analyzed using beta regression adjusted for baseline scores and indicated no additional benefit to receiving the higher dose. However, exploratory interaction models suggested that the efficacy of the high-dose intervention was higher (than low-dose intervention) in participants with higher baseline DSE performance. Parents perceived the intervention to be effective and positive for the family. CONCLUSION The results add to our knowledge of real-world effective online interventions and suggest that a critical minimum language level is required for children with Down syndrome to benefit optimally from a higher intervention dose frequency.

Abstract
PURPOSE We investigated the effectiveness of a highly individualized morphosyntactic intervention using the SHAPE CODING™ system delivered at different dosages. METHOD Eight children with developmental language disorder aged 8;0-10;10 (years;months) received 10 hr of explicit individualized intervention for morphosyntax delivered in 30-min individual sessions once per week for 20 weeks. Following at least four baseline probe tests, two grammatical targets per session received explicit instruction until they reached criterion (90%), when the next target was introduced. To control for session length and teaching episode density, either both targets received 20 teaching episodes per session or one target received 10 teaching episodes and the other 30. Maintenance testing of completed targets was also carried out. RESULTS Scores on probe tests post-intervention were significantly higher than during the baseline phase (d = 1.6) with no change during the baseline or maintenance phases. However, progress during the intervention phase was highly significant. One participant showed significantly faster progress with intervention, while one (with the lowest attention score) made little progress. When considering progress relative to cumulative intervention sessions, progress was faster with 30 teaching episodes per session and slower with 10. However, when cumulative teaching episodes were used as the predictor, all three within-session dosages showed very similar rates of progress, with the odds of a correct response increasing by 3.9% for each teaching episode. The targets that were achieved required an average of 40-60 teaching episodes. CONCLUSIONS With the exception of one participant, the individualized intervention was highly effective and efficient. Thus, the individualized target identification process and intervention method merit further research in a larger group of children. The cumulative number of teaching episodes per target provided across sessions appeared to be key. Thus, clinicians should aim for high teaching episode rates, particularly if the number of sessions is constrained. Otherwise, intervention scheduling can be flexible.

Abstract
PURPOSE This study explored the relation between therapy group size and language outcomes for children receiving school-based language therapy through an implementation science lens. METHOD Data for the current study were gathered as part of the Speech-Language Therapy Experiences in Public Schools study. Participants included 273 English-speaking kindergarten through second-grade children with language impairment receiving business-as-usual therapy on the caseloads of 75 speech-language pathologists. Data were collected over an academic year, including weekly therapy logs, speech-language pathology questionnaires, and pre- and post-language measures. RESULTS Descriptive analysis revealed that children primarily experienced small-group therapy sessions (two to four children); however, there was considerable variability in group size. Hierarchical general linear modeling indicated that caseload size did not explain group size variability. However, the number of student cancellations was positively associated with receipt of large-group sessions. Notably, a significant negative association was found between receipt of large-group sessions (i.e., five to 10 children) and language outcomes. Children who received more than the average number of sessions in large groups (i.e., more than 5% of total sessions) experienced 0.18 SD less language gain over the academic year compared to the mean (0.54 SD). No other group size configurations (i.e., individual, small group, and extra large) yielded significant associations with language outcomes. CONCLUSIONS The findings suggest that young children receiving language-based therapy in large groups make substantially fewer language gains over an academic year. These results have considerable implications for educational policy and clinical practice, which are discussed through an implementation science frame.

Abstract
PURPOSE The most significant document to ensure effective and compliant design, implementation, monitoring, and enforcement of a program of special education services in the United States is the Individualized Education Program (IEP). Although IEPs have been used to document procedural compliance with the Individuals with Disabilities Education Act (IDEA) for individual students, IEPs also provide extensive data that can and should be used by a variety of stakeholders including speech-language pathologists (SLPs), school administrators, and state education agencies to design targeted professional development and collectively improve programs, processes, and outcomes in special education. METHOD We summarize existing literature on the use of IEP data and describe opportunities to use IEP data to analyze individual student service patterns and SLP practice patterns. Aggregated IEP data also provide a robust view of district-wide and state trends in eligibility rates and least restrictive environment settings. Information on current and potential IEP data uses, reflection questions for substantive compliance, and lessons learned from a large-scale analysis of IEP data are provided. These lessons include potential software adjustments to enhance usability as a data source for substantive compliance; program improvement; and monitoring individual, school-wide, and district-wide outcomes. CONCLUSIONS IEP data are a rich data source of information that may be used to (a) identify trends; (b) assist schools, districts, and states with ensuring substantive compliance with IDEA; (c) examine service equity and efficacy; (d) identify professional development needs; and (e) identify promising practices and provide opportunities to use real-time data to improve models and address public policy.

Abstract
PURPOSE The purpose of this study was to examine the measurement structure of the linguistic features of speech-language pathologists' (SLPs) talk during business-as-usual therapy sessions in the public schools and to test the longitudinal stability of a theorized dimensional structure consisting of quantity, grammatical complexity, and lexical complexity. METHOD Seventy-five SLPs' talk during therapy sessions with primary-grade students was automatically transcribed and coded for linguistic features from a corpus of 579 videotaped therapy session videos collected at the beginning, middle, and end of one school year with an approximately 12-week interval. We explored video characteristics and conducted descriptive statistics on eight linguistic indices of SLP talk to examine the variability in SLP talk between therapy sessions. Confirmatory factor analyses were used to explore the dimensional structure of SLP talk at each time point separately for the theorized three dimensions, and we conducted longitudinal measurement invariance analyses to test the stability of the three-factor structural model across the academic year. RESULTS There were considerable variabilities among SLPs in the characteristics of SLP talk during therapy sessions. The proposed three-factor structure of SLP talk consisting of quantity, grammatical complexity, and lexical complexity had good model fit at all three time points. The linguistic measurement properties representing the three factors were invariant over time. CONCLUSIONS Results provided robust evidence of between-SLP variability in their child-directed talk, established a three-dimensional structure of the linguistic features in SLP talk, and identified that the linguistic features in SLP talk stably measured the same constructs across one school year, based on measurement invariance. The dimensions of SLP talk during therapy with students may represent important, malleable features of therapy that influence child language gains.

Abstract
Aided language stimulation is an augmented input strategy that facilitates the expressive and receptive language skills of persons who require augmentative and alternative communication (AAC). The aim of this study was to determine and compare the acquisition of receptive vocabulary items during implementation of aided language stimulation with dosages of 40% and 70%, respectively. An adapted alternating treatment design was replicated across six participants with complex communication needs and severe intellectual disability. All participants demonstrated receptive vocabulary acquisition when aided language stimulation was provided with a dosage of 70%, and two participants demonstrated acquisition when a dosage of 40% was provided. Receptive vocabulary acquisition was maintained following a 6-day withdrawal period. The dosage of augmented input may impact receptive vocabulary acquisition for children with complex communication needs and severe intellectual disability, with higher dosages being more effective for some participants. The findings indicate that clinicians should be aware that dosage is an important consideration when providing aided language stimulation to facilitate receptive vocabulary acquisition in children with complex communication needs and severe intellectual disability.

Abstract
Current methods for reporting interventions do not allow key questions of importance to practitioners, service providers, policy-makers and people with DLD to be answered, and hence limit the implementation of effective interventions in the real world. To extend the existing EQUATOR guidelines to the context of speech language therapy/pathology for children with language disorder and to provide more specific guidance on participants, interventions and outcomes within the CONSORT checklist (used to improve the reporting of randomised controlled trials) and TIDieR (Template for Intervention Description and Replication) to ensure consistency of reporting. We will develop a core team to include representatives from each of the key groups who will either use or be influenced by the final reporting guidance across different countries. To achieve each set of aims, we will conduct reviews of the literature (which present typologies of intervention characteristics in (D)LD and related disorders); carry out focus groups; and use systematic consensus methods such as the Delphi technique, nominal group technique or consensus development conferences. Through the development and adoption of standard intervention reporting criteria, we anticipate that we will overcome the numerous barriers for practitioners, services and policy-makers in applying intervention evidence to practice. We believe that establishing international consensus on reporting guidelines would significantly accelerate progress in DLD research and the ease with which it can be used in clinical practice, by capitalising on the growth in intervention studies to enable international collaboration and new methodologies of data pooling, meta-analyses and cross-study comparisons.

Abstract
PURPOSE The purpose of this pilot study was to determine the impact of including peers with typically developing language (TDL) in language intervention sessions for preschool children with diagnosed developmental language disorder (DLD). METHOD To measure peer effects, participants received 8 weeks of group language intervention in their neighborhood head start. Twenty children with DLD were randomly assigned to one of two conditions. Children in the experimental condition received language intervention with a peer with TDL; children in the control condition received language intervention with another peer with DLD. Pre- and posttest measures of language (semantics, syntax, morphology, and narrative) were collected. Teachers, speech-language pathologists, and assessors were blind to study condition. RESULTS All children in the study showed gains from pre- to posttest; there were no statistically significant differences between conditions. However, effect size estimates (Cohen's d) indicated that the children in the experimental condition showed an advantage over the control condition in syntax, morphology, and narrative. CONCLUSIONS This study provides preliminary evidence that children with DLD show increased gains in language when paired with peers with TDL. This finding supports previous research in educational literature, suggesting that children's development is influenced by the skills of their peers. Additional research is warranted to further explore and understand the role of peers for children with DLD.

Abstract
PURPOSE This investigation adapted a well-studied language treatment method, Enhanced Conversational Recast, paired with auditory bombardment to a teletherapy format. METHOD The study used a single case series approach (n = 7) to determine the feasibility of teletherapy with children ages 5 and 6 years of age. Treatment targeted grammatical errors in the context of dialogic reading and craft activities. Clinicians administered 24 doses in the form of focused conversational recasting, followed by 12 doses consisting of simple sentences containing the grammatical forms targeted for remediation. Children were treated for up to 26 sessions, with four children treated on consecutive weekdays and three treated twice a week. Treatment progress was operationalized as generalization of target grammatical forms to untreated linguistic contexts, as well as spontaneous use of the treated form. To control for nontreatment effects, generalization of an untreated form was also tracked throughout the treatment period. RESULTS Six of the seven children showed clinically meaningful gains in the use of the grammatical forms targeted for treatment within the treatment period. This was true for children enrolled in both treatment schedules. Learning for treated forms was retained after treatment was discontinued. In comparison, no change was seen for untreated forms for six of the seven children. CONCLUSIONS The results suggest that this treatment method is feasible in a telepractice format, even with young children. The range of individual results is generally comparable to previous face-to-face versions of this treatment.

Evaluating two different dose frequencies and cumulative intervention intensities to improve past tense production for early school-aged children with developmental language disorder.

Abstract
AIMS This study compared two dose frequency conditions of an explicit intervention with 50 trials per session designed to improve past tense marking in early school-aged children with developmental language disorder (DLD). The influence of allomorphs on intervention effects was also examined. METHODS Data from previously conducted intervention studies were combined and analysed. Participants included nine children (mean age = 6;5 years) who received 20-30-min intervention sessions provided twice per week for 10 weeks (1000 trials; 400-600 min) and 20 children (mean age = 6;6) who received 20-30-min intervention sessions provided once per week for 10 weeks (500 trials; 200-300 min). Repeated measures included criterion-referenced probes for production of untrained past tense verbs collected throughout baseline, intervention, and maintenance phases. The rate of progress in each phase was analysed using logistic regression. The proportion of participants who produced past tense allomorphs correctly at pre-intervention, post-intervention, and maintenance testing points was analysed. RESULTS Logistic regression showed a stable baseline, highly significant progress during the intervention phase, and a marginally significant shallow decline during the maintenance phase. Those in the twice per week group showed a greater rate of progress during the intervention phase leading to significantly higher scores in the maintenance period when compared with the once per week group. The allomorphic category of past tense verbs did not appear to influence outcomes. CONCLUSIONS Participants receiving intervention twice per week appeared to demonstrate a greater rate of progress with intervention than those receiving it once per week, although once per week was also effective. However, these results should be interpreted with caution. Limitations to study design indicate that a larger randomised controlled trial is required. All past tense allomorphs improve to a similar degree when treated with this intervention. WHAT THIS PAPER ADDS What is already known on the subject Understanding the parameters of dosage and intensity are important for clinical practice. Research evaluating the efficacy and/or effectiveness of interventions delivered in different dose/intensity conditions is scarce. There appears to be different interpretations of what constitutes dosage and intensity in published research. What this paper adds to existing knowledge This study retrospectively compared dosage and intensity conditions of intervention provided twice per week to intervention provided once per week. Both dose frequencies could be delivered in clinical settings. Results from this study were analysed by grouping data from multiple testing points, rather than comparing pre-post results. This approach demonstrated the variability of individual performance that would otherwise be lost with conventional methods of analysis. This study demonstrated that all past tense allomorphs improve to a similar degree when treated with this intervention. What are the potential or actual clinical implications of this work? Parameters of dosage and intensity are still not clearly defined well enough for translation to clinical practice. In consideration of current research, this intervention may be more effective if delivered twice per week. If clinicians are treating past tense, all allomorphs should be considered as priorities for intervention targets.

Abstract
PURPOSE Research on treatment intensity in children with developmental language disorder (DLD) has undergone substantial development over the last decade. The aim of the present review was to analyse available publications as related to methodological quality, degree of scientific evidence, and the areas/aspects of language involved. METHOD A systematic review of the scientific literature was conducted using the PRISMA guidelines. A total of 9 articles from 34 published investigations in the field were selected for review according to our inclusion criteria. RESULT The articles addressed the effects of treatment intensity primarily considering expressive morphology and vocabulary. The methodological quality and levels of evidence provided by the studies were high. In general, the effect sizes of dependent variables were considered large. CONCLUSION The number of articles investigating treatment intensity in DLD is scarce. High variability of stimuli was associated with improvements in morphology, whereas vocabulary did not demonstrate the same association. Further research on treatment intensity is needed to address transference and generalisation of the treated abilities.

Abstract
PURPOSE The aim of this study was to explore the reasons behind speech-language pathologists' (SLPs') current clinical practices (intervention and intensity provision) for children (0-18 years) with phonological impairment. METHOD Three focus groups each with five SLPs and six 1:1 interviews with SLP managers from one region of the UK (n = 21) were carried out. A thematic analysis was undertaken. RESULT SLPs often used an eclectic mix of familiar approaches with easily-accessible therapy materials. SLPs only reported deviating from their core approach if the child did not progress in therapy. Mixed responses were gathered on the perceived feasibility of transferring evidence-based intervention intensities into clinical practice. The importance of parents to increase intensity provision at home was noted. Barriers to SLPs' evidence-based decision-making included: time; confidence levels; service-related restrictions and; difficulty replicating research in practice. Having peer support and access to decision-making pathways and manualised intervention protocols were considered ways to overcome these barriers. CONCLUSION There is a research-practice gap in which SLPs' current practices are driven by organisational factors, their own preferences and child-specific factors. To narrow this gap, SLPs suggested the development of time-saving, evidence-based tools.

Abstract
Children with speech sound disorders (SSDs) represent a large proportion of clients served by school-based speech-language pathologists (SLPs). While considerable evidence is available regarding the identification of SSD in school-age children, there is a paucity of information regarding service delivery aspects of school-based speech therapy, such as frequency of sessions, number of trials, distribution of sessions over time, and format (individual or group intervention) that impacts the ability of SLPs to effectively treat SSD in the schools. School-age children with SSD are at risk for later literacy deficits, and strategically addressing their language and emerging literacy needs in addition to speech production accuracy may lead to increased intelligibility and better educational outcomes. In this article, we discuss the heterogeneity of school-age children with SSD with regard to weaknesses in phonological processing skills and language skills. We summarize the information currently available regarding the aspects of service delivery that contribute to gains in speech production accuracy. We conclude by sharing an example of how school-based SLPs could target speech production, phonological awareness, and morphological awareness in the same session with a child with SSD to maximize gains in speech and literacy skills.

Abstract
Background International debate around the best models of speech and language therapy provision for children with language disorders has highlighted the need for research into classroom-based approaches and intervention dosage. Working memory (WM) is a cognitive skill linked to attention and language. ‘Recall to Enhance Children’s Attention, Language and Learning’ (RECALL) is a novel, 6-week, classroom-based intervention delivered by health professionals (HPs) and teachers. It is designed to target WM and enhance attention and language skills in 4–5 year olds. Methods A cluster randomised feasibility trial was conducted to investigate aspects of the feasibility of a definitive trial to evaluate RECALL: (i) recruitment and sampling procedures; (ii) compliance and fidelity; (iii) the acceptability of RECALL to HPs and teachers; (iv) the appropriateness of the outcome measures. Six classes of 4–5 year olds participated: two received RECALL, two received an existing intervention targeting attention skills (not underpinned by WM theory), and two received education as usual (no intervention). Ten children in each class (n = 60) were sampled to assess the appropriateness of the outcome measures. Classroom observations were conducted to measure fidelity and semi-structured interviews with HPs, and teachers explored the acceptability of RECALL. Results The recruitment targets were met, and all six schools completed the trial, but the sampling procedures require modification. Compliance was good (95% of RECALL sessions were delivered), but fidelity to the intervention protocol varied between 76% and 45% across the two schools. This was influenced by large class sizes, child factors, and facilitator factors, e.g., their understanding of the theory underpinning the intervention. The lack of fidelity reduced the dose (number of practice items) accessed by individual children, particularly those most at risk. There were mixed findings regarding the acceptability of RECALL and the appropriateness of the outcome measures. Conclusions The trial protocol could be easily scaled-up in a future definitive trial, with an amended sampling procedure. RECALL should be repackaged as a small group intervention to enhance the fidelity of its delivery and its acceptability to HPs and teachers. This study highlights the need for thorough training for professionals who deliver classroom-based interventions for children with language disorders. Trial registration ISRCTN13633886.

Abstract
Purpose This study examined intervention intensity and service delivery with school-age children with mild or mild-moderate speech sound disorders. The commonly used business-as-usual (BAU) service delivery model and a shorter, more frequent, individual model (experimental [EXP]) were compared. Method A between-subjects group design was selected. In BAU, 11 children received group sessions, 2 times per week, 30 min per session for 6 weeks. In EXP, 11 children received individual session, 3 times per week, 5 min per session for 6 weeks. Group differences on measures of dose (i.e., therapeutic input and production trials) and cumulative treatment intensity were examined. The extent to which children, across both conditions, demonstrated gains in speech sound accuracy and the extent to which gains differed between BAU and EXP were examined. Results There was a significant group difference on dose. Children in BAU received more therapeutic input and production trials than children in EXP. Cumulative treatment intensity was not statistically different between groups when dose was calculated as therapeutic input or production trials. Results from both conditions indicated statistically significant differences on measures of speech sound accuracy with large effect sizes. No group differences on gains were noted. Conclusions Dose calculated as therapeutic input and production trials plays an important role in understanding the impact of cumulative intervention intensity. Children with mild or mild-moderate speech sound disorders may benefit more from a shorter, frequent, individual service delivery model than a BAU model.

Abstract
Purpose The aim of this study was to examine the degree to which quantitative aspects of dosage (dose, dose frequency, and total intervention duration) have been examined in intervention studies for children with developmental language disorder (DLD). Additionally, to establish the optimal quantitative dosage characteristics for phonology, vocabulary, and morphosyntax outcomes. Method This registered review (PROSPERO ID CRD42017076663) adhered to PRISMA guidelines. Search terms were included in seven electronic databases. We included peer-reviewed quasi-experimental, randomized controlled trial or cohort analytical studies, published in any language between January 2006 and May 2020. Included articles reported on participants with DLD (M = 3-18 years); oral language interventions with phonology, vocabulary, or morphosyntax outcomes; and experimental manipulation or statistical analysis of any quantitative aspect of dosage. Studies were appraised using the Cochrane risk-of-bias tool. Results Two hundred forty-four articles reported on oral language interventions with children with DLD in the domains of interest; 13 focused on experimentally/statistically manipulating quantitative aspects of dosage. No article reported phonological outcomes, three reported vocabulary, and eight reported morphosyntax. Dose frequency was the most common characteristic manipulated. Conclusions Research is in its infancy, and significant further research is required to inform speech-language pathologists in practice. Dosage characteristics are rarely adequately controlled for their individual effects to be identified. Findings to date suggest that there is a point in vocabulary and morphosyntax interventions after which there are diminishing returns from additional dosage. If dose is high (number of learning opportunities within a session), then the literature suggests that session frequency can be reduced. Frequent, short sessions (2/3 × per week, approximately 2 min) and less frequent, long sessions (1 × per week, approximately 20 min) have yielded the best outcomes when composite language measures have been used; however, replication and further research are required before clinicians can confidently integrate these findings into clinical practice.

Abstract
Background & aims Difficulties understanding spoken language are associated with several social and academic risks in school-age children and adolescents with developmental language disorder (DLD). Still, interventions for this group have received little attention, and there are no reviews focusing on oral language comprehension interventions in school-age children and adolescents. The objective of this systematic scoping review was to identify interventions targeting oral language comprehension in school-age children and adolescents with DLD. Further, the aim was to examine the focus of intervention, efficacy, and level of evidence of the identified interventions. The present review is the second part of a larger search on oral language comprehension interventions. The first review examined the same factors in children 8 years and younger. Methods A systematic scoping review of eight databases was conducted. Of the 2399 sourced articles, 12 met the inclusion criteria. Another 8 articles were identified through reference lists of sourced articles. In these 20 articles, containing 21 studies, 1661 children aged 5-16 years participated. The data were extracted and analysed, and the intervention focus, efficacy, and level of evidence were examined.Main contribution: In the interventions intended for school-age children and adolescents with DLD, three intervention foci were identified that targeted aspects of language and language processing, as well as modifying the communicative environment. Of the included studies, 57% reported positive results, 14% reported mixed results, and 29% reported no effects on oral language comprehension. The level of evidence varied. One can have high confidence in the results of 19%, moderate in 38%, and indicative confidence in 43% of the included studies. Conclusions Results of the present review suggest that there are a few interventions providing high confidence on the efficacy of improving oral language comprehension difficulties in school-age children and adolescents with DLD. Most interventions indicating efficacy provide moderate or indicative confidence in the results. More research with a high level of evidence is urgently needed. Most of the interventions indicating efficacy focused directly on language skills or modified the communicative environment. The results suggest that the therapy techniques focusing on improving language processing skills indicate efficacy only when they aim at compensating current language processing skills, not trying to improve them.Implications: The findings on different therapy techniques, their focus of intervention, efficacy, and level of evidence provide information for clinical practice and direct future investigations in this sparsely researched topic.

Abstract
Purpose The current study examined children's engagement as an active ingredient of language therapy in public schools and considered the potential interplay between engagement and dose on outcomes. Method Participants included 135 children with language impairment receiving business-as-usual therapy from 70 speech-language pathologists. Two videotaped therapy sessions from each participating child were coded for children's level of engagement and time in language-focused therapy (dose). Results Hierarchical linear modeling was used for analyses; children's level of engagement (i.e., active engagement) was significantly, positively related to children's language gain and was not moderated by dose. Conclusion Findings suggest that children's active participation in therapy sessions is a significant component to effective language therapy and underscores the need for further research.

Abstract
Purpose Researchers in the cognitive sciences have identified several key training strategies that support good encoding and retention of target information. These strategies are retrieval-based practice, also known as learning through testing, and spaced practice. The recent resurgence of research on retrieval-based and spaced practice has been extended to investigate the effectiveness of these strategies to support learning in individuals with language disorders. The purpose of the current article is to review key principles of retrieval-based and spaced practice that can be used to support word learning in individuals within clinical and educational contexts. Conclusion Current research provides evidence that principles of retrieval-based and spaced practice can enhance word learning for individuals with language disorders. Current research provides guidance for clinicians on how to implement these strategies both within and across sessions to support encoding and retention of target information. Additional research should be conducted to provide a better understanding of how to optimize encoding and retention in clinical and educational contexts. Most notably, research that examines long-term retention after interventions are withdrawn would further our understanding of how these principles can be optimally applied to improve outcomes for individuals with language disorders.

Abstract
Purpose The purpose of this study was to explore the extent to which child- and therapy-level factors contribute to gains in speech sound production accuracy for children with speech sound disorders in receipt of school-based services. Method Data were obtained from 126 kindergarten and first- and second-grade children currently in receipt of speech therapy services in their public school setting. Pretest and posttest measures of spontaneous speech production and language ability were collected at the beginning and end of one academic year. Using a spontaneous speech sample, percentage of consonants correct (PCC) was calculated for each child; a gain score was computed by subtracting the pretest PCC score from the posttest PCC score. The children's speech-language pathologist completed weekly therapy logs during business-as-usual therapy, indicating the frequency, duration, and group composition of services throughout the school year. Results Results supported that gain in PCC from pretest to posttest was predicted by several child- and therapy-level variables. Children's initial speech sound severity was negatively related to gains in PCC. Our results also supported that the total number of therapy sessions received in a year was positively predictive of PCC gain. Interestingly, the number of individual therapy sessions was negatively associated with PCC gain. Conclusion Several malleable therapy factors contribute to gains in speech sound accuracy for children with speech sound disorders. Speech-language pathologists should consider how these factors may be manipulated to best tailor treatment to the individual needs of the children on their caseloads.

Abstract
BACKGROUND AND AIMS The most severe problems in language manifest as difficulties in comprehending oral language. These difficulties are persistent and expose individuals to several risk factors. There is a lack of intervention research in the area of oral language comprehension, and no reviews have focused solely on oral language comprehension interventions in young children. The aim of this review was to identify interventions targeting oral language comprehension in children 8 years or younger with language disorders or difficulties. The review also examined the possible intervention foci, efficacy, and level of evidence of these interventions. METHODS A systematic scoping review of eight databases was carried out. Twenty of 2399 articles met the inclusion criteria and a further six articles were identified through reference lists of sourced articles. These 26 articles described 25 studies. Altogether 2460 children aged 1-8 years participated in the 25 studies. The data from these studies were extracted and analysed, and the intervention foci, efficacy, and level of evidence were evaluated.Main contribution: The reviewed interventions focused on three aspects: modifying the communicative environment of the child; targeting aspects of the child's language; or targeting the child's language processing. Of the included studies, 80% indicated positive effects on participants' oral language comprehension. The level of evidence of the included studies varied. With few exceptions, researchers and practitioners can have moderate confidence in the results of the included studies indicating that it is possible to ameliorate difficulties in oral language comprehension. CONCLUSIONS This review summarises the existing evidence on oral language comprehension interventions in young children with language disorders or difficulties. The evidence base is still limited, and more research is urgently needed. The results suggest that though not all interventions seem to provide desired outcomes, there are several interventions indicating efficacy to target problems in oral language comprehension in 1-8-year-old children with language disorders or difficulties. A careful choice of therapy technique and collaboration with people in the child's environment is required to maximize outcomes.Implications: The results suggest that young children's oral language comprehension skills can be improved by guiding parents and clinicians in their communication strategies, and by clinician-implemented interventions targeting aspects of the child's language. The research on interventions targeting children's language processing is limited, and the results mixed. The present study provides information on different oral language comprehension interventions and their outcomes. The findings are readily applicable for clinical use.

Abstract
BACKGROUND Across the world, research has shown that intervention for children with phonological impairment can be both effective and efficient. However, it has also raised concerns about the translation of this evidence to practice, highlighting questions around clinician knowledge and the understanding of approaches, and the intensity of intervention provided within real-life clinical contexts. AIMS To investigate the clinical management of phonological impairment by speech and language therapists (SLTs) in the United Kingdom (UK). METHODS & PROCEDURES An anonymous, UK-wide, online survey was developed using Qualtrics. The target audience were UK-based SLTs who worked with children with phonological impairment. The following topics were explored: (1) SLTs' understanding of intervention approaches; (2) SLTs' use of intervention approaches to treat phonological impairment; and (3) SLTs' provision of intervention intensity for children with phonological impairment. OUTCOMES & RESULTS A total of 166 responses were analyzed. To remediate phonological impairment, SLTs most commonly used speech discrimination (79.5%), conventional minimal pairs (77.3%), phonological awareness therapy (75.6%) and traditional articulation therapy (48.4%). Participants least frequently used the complexity approaches targeting the empty set (82.9%) and two- to three-element clusters (75%) as well as the cycles approach (75.6%). Results also showed that some SLTs were uncertain of what the empty set and two- to three-element clusters approaches entailed. In terms of intervention intensity, participants predominantly provided intervention once per week (69%) for a total of 9-12 sessions (ranging from five to 30 sessions, 71.5%) and elicited targets 10-30 times in single words per session (59.4%) in sessions lasting 21-30 min (41.4%). CONCLUSIONS & IMPLICATIONS The most commonly used intervention approaches identified in the current survey (i.e., speech discrimination, conventional minimal pairs and phonological awareness therapy) may be used eclectically by SLTs, which could impact upon the effectiveness and efficiency of treatment for phonological impairment. The current study also highlighted that almost half the participants always/often used traditional articulation therapy to remediate phonological impairment, even though this approach has been found to be less effective for this difficulty. Additionally, it appears that the currently provided intervention intensity for phonological impairment in the UK is significantly lower than what is indicated in the literature. Therefore, a research-practice gap exists for SLTs in the UK working with children with phonological impairment.

Abstract
Dose is a particularly important element of treatment for speech and language disorders, yet relatively little is known concerning how best to operationalise dose in clinical settings. This keynote provides an overview of dose as a theoretical and empirical concept and discusses recent findings that question whether "more is better" when treating children with language disorders. Given recent evidence showing that spaced treatments may result in optimal gains for children, I argue that low-frequency therapy sessions can be especially beneficial for children with language disorders when they are highly productive, providing children with high levels of dose.
