Validity of the Communication Function Classification System for use with preschool children with communication disorders

Assessing aspects of early social communication in non-speaking children with bilateral cerebral palsy

PURPOSE

Research suggests that rates for autism may be higher in cerebral palsy than in the general population. For those with severe bilateral physical impairment (GMFCS level IV and V) and little or no speech, describing a profile of social communication skills has been difficult because there are currently no assessments for early social communication specifically tailored for these children. Our aim was to explore the assessment of aspects of joint attention and social reciprocity in this group of children with CP.

METHODS

We compared the performance of children with bilateral CP on carefully designed assessments of joint attention and social responsiveness with groups of children with Down syndrome and autism. All three groups were matched for chronological age and mental age.

RESULTS

Approximately 30% of the children with bilateral CP had early social communication scores similar to the autistic children. The remaining 70% of children with CP had a range of early social communication scores similar to the children with Down syndrome.

CONCLUSION

It is possible to assess key early social communication skills in non-speaking children with bilateral motor disability. This could provide insights to help clinicians and caregivers as they discuss abilities and explore potential areas for intervention.

Developmental language disorder and neurodiversity: Surfacing contradictions, tensions and unanswered questions

BACKGROUND

Neurodiversity is increasingly discussed in relation to autism research and practice. However, there is a lack of scholarship concerning the neurodevelopmental condition of Developmental Language Disorder (DLD) and the neurodiversity movement. While this movement may hold opportunities for the DLD community, the application of the concept of neurodiversity to DLD research and practice needs consideration, as DLD and autism have very different levels of public and professional awareness and understanding.

AIMS

In this article, we discuss what the concept of neurodiversity and the associated neurodiversity movement could mean for DLD research and practice. We aim to critique some assumptions that may arise from the application of neurodiversity principles (or assumed principles) to the field of DLD.

METHODS

This is a discussion paper, drawing on the personal experiences and reflections of the author team.

MAIN CONTRIBUTIONS

We make the case for why DLD should be included in discussions about neurodivergence and outline considerations for doing so, and why some issues and applications may be particular to DLD. We outline points of similarity and contrast with autism in relation to our understanding of neurodiversity. We consider the issues around diagnosis and terminology and urge practitioners to continue to diagnose DLD using currently agreed terminology, so as not to undermine recent awareness efforts. We note that a neurodiversity-informed perspective challenges us to offer interventions that operate at the level of our environments, not just at the level of an individual. Indeed, neurodiversity offers a platform to argue for better rights and more inclusive spaces in mental health settings, education and work for children and adults with DLD.

CONCLUSIONS

DLD should be considered from a neurodiversity-informed perspective, and it is our hope that this will lead to neurodiversity-affirming practice that will afford young people with DLD better understanding from members of the public and the professionals who work with them. Further work is needed to better support children, young people and adults with DLD to have a voice in the neurodiversity movement.

WHAT THIS PAPER ADDS

What is already known on the subject Neurodiversity approaches are increasingly being taken up in research and practice in relation to autism, meaning that our understanding of autism and how autistic people are supported is increasingly drawing on the principles of neurodiversity. However, autism is not the only neurodivergent population. Developmental Language Disorder (DLD) is another neurodevelopmental condition; however, relative to autism, DLD has lower awareness amongst professionals and the public. There has been no scholarship that has examined DLD through the lens of neurodiversity, or considered the application of neurodiversity-affirming approaches to DLD. What this paper adds to existing knowledge In this paper, we examine what the neurodiversity movement means for DLD research and practice. In particular, we consider what neurodiversity in the field of autism might teach us about the application of neurodiversity in the field of DLD, and highlight where we believe there are important differences between the two populations. We reflect on what neurodiversity means for intervention, diagnosis, terminology and championing the need for accessibility, especially with regard to mental health support, education and employment. What are the potential or actual clinical implications of this work? Neurodiversity highlights the need to consider interventions at the level of an individual's environment (e.g., how can we make this space more inclusive?) as well as interventions operating at the level of the individual themselves (e.g., interventions focusing on an individual's language skills). We challenge the notion that neurodiversity-affirming approaches mean not diagnosing DLD or changing DLD's terminology: we argue that this is not in the spirit of the original neurodiversity movement, but also that for a condition with such low public awareness, these actions could do more harm than good for families affected by DLD. We call for more in-depth scholarship and discussion around the application of neurodiversity approaches to DLD and argue that the neurodiversity movement offers an important opportunity to raise better awareness and understanding of DLD in multiple sectors, including (but not limited to) mental health, education and employment.

Speech-language pathologists' treatment goals for preschool language disorders: An ICF analysis

PURPOSE

The World Health Organization's International Classification of Functioning, Disability and Health (ICF) provides a comprehensive framework to conceptualise clinical services. This study explored how speech-language pathologists (SLPs) conceptualised therapy goals for preschoolers with language difficulties and disorders within the ICF framework.

METHOD

An online survey was distributed to SLPs practising in a publicly funded Preschool Speech and Language program in Ontario, Canada. SLPs rated their familiarity with the ICF framework, and then reported all therapy goals for one child with language difficulty/disorder on their caseload. For each reported goal, SLPs indicated the ICF component(s) they felt the goal addressed. Researchers then independently categorised SLPs' reported goals into the ICF components.

RESULT

Ninety-three SLPs completed the survey, and 81% reported they were at least "somewhat" familiar with the ICF framework. On average, SLPs reported three therapy goals per child, and felt the Activities and Participation components were most frequently targeted (73% and 72% of all reported goals, respectively). Researchers categorised SLPs' reported goals differently, and identified 57% of goals addressing the Activities component, and 21% the Participation component.

CONCLUSION

There is a need to better understand how SLPs and researchers conceptualise the ICF framework, particularly the Participation component.

Kindy Moves: the feasibility of an intensive interdisciplinary programme on goal and motor outcomes for preschool-aged children with neurodisabilities requiring daily equipment and physical assistance

OBJECTIVES

To determine the feasibility of an intensive interdisciplinary programme in improving goal and motor outcomes for preschool-aged children with non-progressive neurodisabilities. The primary hypothesis was that the intervention would be feasible.

DESIGN

A single group feasibility study.

SETTING

An Australian paediatric community therapy provider.

PARTICIPANTS

Forty children were recruited. Inclusion criteria were age 2-5 years with a non-progressive neurodisability, Gross Motor Function Classification System (GMFCS) levels III-V or equivalent, and goals relating to mobility, communication and upper limb function. Exclusion criteria included orthopaedic surgery in the past 6 months, unstable hip subluxation, uncontrolled seizure disorder or treadmill training in the past month.

INTERVENTION

A goal-directed programme of three 2-hour sessions per week for 4 weeks (24 hours total). This consisted of treadmill and overground walking, communication practice, and upper limb tasks tailored by an interdisciplinary team.

PRIMARY AND SECONDARY OUTCOME MEASURES

Limited-efficacy measures from preintervention (T1) to postintervention (T2) and 4-week follow-up (T3) included the Goal Attainment Scaling (GAS), Canadian Occupational Performance Measure (COPM), Gross Motor Function Measure (GMFM-66) and 10-Metre Walk Test (10MWT). Acceptability, demand, implementation and practicality were also explored.

RESULTS

There were improvements at T2 compared with T1 for all limited-efficacy measures. The GAS improved at T2 (mean difference (MD) 27.7, 95% CI 25.8 to 29.5) as well as COPM performance (MD 3.2, 95% CI 2.8 to 3.6) and satisfaction (MD 3.3, 95% CI 2.8 to 3.8). The GMFM-66 (MD 2.3, 95% CI 1.0 to 3.5) and 10MWT (median difference -2.3, 95% CI -28.8 to 0.0) improved at T2. Almost all improvements were maintained at T3. Other feasibility components were also demonstrated. There were no adverse events.

CONCLUSIONS

An intensive interdisciplinary programme is feasible in improving goal and motor outcomes for preschool children with neurodisabilities (GMFCS III-V or equivalent). A randomised controlled trial is warranted to establish efficacy.

Perceptions of families with adolescents utilizing augmentative and alternative communication technology: A qualitative approach

PURPOSE

Although family involvement is critical to successful augmentative and alternative communication (AAC) device utilization, little is known about how families adapt to technology. The aim of this qualitative study was to explore parent-reported factors contributing to family adaptation among families with adolescents diagnosed with autism and/or Down syndrome (DS) utilizing AAC technology. This study describes families' experiences related to several interacting variables of the Resiliency Model, including demand, type, appraisal, resources, and problem-solving/coping, that helped shape the outcome of adaptation to AAC technology. Nurses are well-positioned in a variety of practice settings to assess vulnerable families and assist with identifying resources and navigating complex service systems.

DESIGN AND METHODS

Semi-structured interviews were conducted with eight parents of adolescents with autism and/or DS (aged 13-18) recruited through online research registries, support organizations, and a social networking site. Recorded interviews were transcribed, and two independent reviewers coded and analyzed the data. Comparisons across all families' thematic summaries were examined for patterns.

RESULTS

Five themes described aspects of family adaptation: Contextual Strains and Influences, Continuum of Person-First Approach, Opening Doors, Facilitators of Support, and Planning Is Key.

CONCLUSIONS

Findings highlighted the challenges and demands associated with raising an adolescent using an AAC device, as well as the attributes, resources, perceptions, and strategies that either contributed or hindered family adaptation.

PRACTICE IMPLICATIONS

AAC technology is readily available for adolescents with developmental disabilities. It is essential that nurses assess key adaptation components to support families in integrating and using the technology.

Kindy Moves: a protocol for establishing the feasibility of an activity-based intervention on goal attainment and motor capacity delivered within an interdisciplinary framework for preschool aged children with cerebral palsy

INTRODUCTION

Preschool aged children with cerebral palsy (CP) and like conditions are at risk of performing below their peers in key skill areas of school readiness. Kindy Moves was developed to support school readiness in preschool aged children with CP and like conditions that are dependent on physical assistance and equipment throughout the day. The primary aims are to determine the feasibility of motor-based interventions that are functional and goal directed, adequately dosed and embedded into a play environment with interdisciplinary support to optimise goal-driven outcomes.

METHODS AND ANALYSIS

Forty children with CP and like conditions aged between 2 and 5 years with a Gross Motor Function Classification System (GMFCS) level of III-V or equivalent, that is, dependent on physical assistance and equipment will be recruited in Western Australia. Participants will undertake a 4-week programme, comprised three, 2-hour sessions a week consisting of floor time, gross motor movement and play (30 min), locomotor treadmill training (30 min), overground walking in gait trainers (30 min) and table-top activities (30 min). The programme is group based with 3-4 children of similar GMFCS levels in each group. However, each child will be supported by their own therapist providing an interdisciplinary and goal directed approach. Primary outcomes of this feasibility study will be goal attainment (Goal Attainment Scale) and secondary outcomes will include Canadian Occupational Performance Measure, 10 metre walk test, Children's Functional Independence Measure, Sleep Disturbance Scale, Infant and Toddler Quality of Life Questionnaire, Peabody Developmental Motor Scale and Gross Motor Function Measure. Outcomes will be assessed at baseline, post intervention (4 weeks) and retention at the 4-week follow-up.

ETHICS AND DISSEMINATION

Ethical approval was obtained from Curtin University Human Ethics Committee (HRE2019-0073). Results will be disseminated through published manuscripts in peer-reviewed journals, conference presentations and public seminars for stakeholder groups.

Children's Perspectives on Mealtimes When Living with a Gastrostomy Tube: A Qualitative Study

PURPOSE

To explore children's experiences of mealtimes when living with a gastrostomy tube.

DESIGN AND METHODS

The study used a qualitative descriptive design framed within ecocultural theory. Seven children, three girls and four boys, aged 6-12 years with long-term health conditions and a gastrostomy tube participated in individual interviews. The interviews were qualitatively analysed by means of systematic text condensation.

RESULTS

Four main categories comprised the findings of the children's mealtimes experiences: "Stable in form, open to variation," "An individual, and a shared activity," "An object that needs to be dealt with" and "A part of me." A complex picture emerged, where the children experienced nutrition, whether through the gastrostomy tube or orally, as necessary for a healthy body, although this did not suffice to make the mealtime experience positive.

CONCLUSIONS

Regardless of the children's amount of oral intake, everyday mealtimes were valued as opportunities for social interaction and experienced as a predictable, routine activity no different from the mealtimes of other families. The accounts illustrated that in many situations the children knew precisely what they needed and did not need, what they liked and disliked and why.

PRACTICE IMPLICATIONS

Healthcare professionals should take children's knowledge into consideration to a greater extent when planning follow-up and intervention. The study illuminates that children can take an active part in their healthcare when offered flexible and carefully designed communication material, even in the presence of communicative and/or intellectual disability.

Stability of the Communication Function Classification System among Children with Cerebral Palsy in South Korea

Interest in the prognosis of skill levels has been an important issue among children with cerebral palsy (CP). This study aimed to verify the stability of the Communication Function Classification System (CFCS) in 2- to 18-year-old children with CP. Data collected from 171 children with CP who received rehabilitation therapy in hospitals or attended special elementary schools in South Korea were reviewed. They were divided into two groups, children <4 years and children ≥4 years. Participants were evaluated over 1-year and 2-year intervals from the first rating. Agreement between the three measurements and the weighted kappa were analyzed. At the 1-year interval, results demonstrated a high agreement rate of the CFCS in children ≥4 years old, and during the 2-year interval the study revealed a low agreement rate in children aged 2–4 years. The results indicated the stability of the CFCS in children ≥4 years old but some change of the CFCS in 2- to 4-year-old children. Moreover, the findings suggested that the change of the CFCS varied with time and age. Based on these results, it is recommended that the CFCS assessments be performed periodically, especially among 2- to 4-year-old children with CP.

Assessing communicative participation in preschool children with the Focus on the Outcomes of Communication Under Six: a scoping review

AIM

To describe uses of the Focus on the Outcomes of Communication Under Six (FOCUS) in research with children with and without various communication disorders since its publication in 2010.

METHOD

Six databases were searched for the term 'Focus on the Outcomes of Communication Under Six'. With additional searches we ascertained 70 articles, of which 25 met inclusion criteria for full review and data extraction.

RESULTS

The FOCUS has been used in research across multiple countries, purposes, populations, contexts, and versions. Evaluative studies have described: the development of children's communicative participation skills and factors that impact the development of communicative participation; the impact of specific interventions on communicative participation; how FOCUS captures change relative to measures of impairment; and how FOCUS performs when used at different intervals. Adaptations have included: use of the FOCUS as a descriptive or discriminative tool; use with children outside the validated age range; use of select items; and use with typically developing children.

INTERPRETATION

The FOCUS is used worldwide in research and practice, and much has been learned about children's communicative participation. Future research is needed to explore the relationship between children's impairments and their communicative participation, develop a FOCUS App, and develop and validate a FOCUS for school-age children.

Exploring young children’s activity and participation change following 6 months’ power mobility experience

Introduction

This pre-post study explored the effect of children’s 6 months’ experience in one of four early power mobility devices.

Method

Satisfaction with parent-selected goal achievement was measured using the wheelchair outcome measure for young people and compared with the assessment of learning powered mobility use, as well as device expectation fulfilment ratings.

Results

Forty-six children with mobility limitations, aged 13–68 months (mean 40.40; SD 15.60) participated. The most common condition was cerebral palsy ( n = 33; 71.74%). The Wilcoxon signed rank test measured the positive change in goal achievement ( z = 4.90; P<0.001; r = 0.51). Fair to good statistically significant Spearman’s correlations were observed between power mobility skill and goal achievement, as well as parent and therapist device expectation scores ( rs = 0.48, 0.46 and 0.66, respectively; P<0.001). Parent and therapist ratings did not differ significantly. No statistically significant associations were found between goal achievement and child (age, diagnosis, abilities) or environmental factors (device, access method, loan length).

Conclusion

Children at all phases of power mobility skill, using various devices and access methods, can demonstrate activity and participation change following power mobility experience. This study adds validity evidence supporting the use of the wheelchair outcome measure for young people with young children by parent-proxy rating.

Exploring change in young children's power mobility skill following several months' experience

PURPOSE

To measure and compare progression in children's power mobility skill among process and task-based measures following a loan of one of four early power mobility devices. Additionally, to explore different power mobility learner groups and skill development trajectories.

METHODS

In this pre-post study, children were purposefully sampled and power mobility skill was measured from video taken pre-post several months' experience (mean 192.40; SD 42.79 days) using the Assessment of Learning Powered mobility use (ALP) and two task-based measures. Associations among power mobility skill measures were examined. Child and environmental factors influencing ALP phase at loan-end were explored.

RESULTS

Forty-six children aged 13 - 68 months (mean 40.40; SD 15.60) participated, with cerebral palsy being the most common condition (n = 33; 71.74%). ALP change scores ranged from -2 to +4 ALP phases (median 1.0). Wilcoxon signed rank test was significant for pre-post differences with a large effect size (z = 5.50, p < 0.001; r = 0.57). End-of-loan Spearman correlations between ALP and two task-based paediatric measures were excellent (r_s = 0.92). Kruskal-Wallis test revealed significant effect of device, access method, diagnostic group and communication abilities on loan-end ALP phase.

CONCLUSION

Positive change was demonstrated with most children (n = 39; 84.78%) changing at least one ALP phase during the study. Positive change was seen with children at all phases of tool-use, using all devices and access methods. Process and task-based measures were highly correlated, but differed in application for different learner groups. Different trajectories of skill development may be associated with different child profiles and access abilities.IMPLICATIONS FOR REHABILITATIONChildren at all phases of tool-use can demonstrate positive change in power mobility skill using different devices and switch as well as joystick access methodsThe Assessment of Learning Powered mobility use (ALP) is useful for assessing tool-use and learning process skills for young children across the power mobility skill continuum.Task-based measures may also be helpful for guiding training and recording progress; The Power Mobility Training Tool (PMTT) is most useful for children exploring cause-effect and direction (ALP Phases 1-5), while the Power Mobility Program (PMP) is most useful for functional learners and those progressing from exploring direction to functional use (ALP Phases 5-8).Access method may influence power mobility learning trajectory and training.

Needs of Families with Children with Cerebral Palsy in Latvia and Factors Affecting These Needs

In order to provide targeted support to families who are raising children with developmental disorders, it is important to study the family needs and to understand circumstances that may affect them. The aim of this study was to identify the needs of the families with preschool children with cerebral palsy, and study how these needs relate to factors associated with families, children and rehabilitation services. Descriptive analysis showed that families living in Latvia most often need information, social and financial support and coordination of services, and they also need financial support to cover the costs of child care and treatment. The results of the data analysis support the hypothesis that factors characterising families, children with cerebral palsy and rehabilitation services affect the needs of the families with preschool children with cerebral palsy living in Latvia, and the unique impact of these factors depends on the type of needs. Regression analysis revealed that the most important factors affecting the needs of families were related with the socio-economic situation, as well as the support of peers and professionals. The availability and regularity of rehabilitation services, limitations to the child's functions and health impairments were factors that affected family needs to a lesser extent.

Lessons learned in practice-based research: Studying language interventions for young children in the real world

BACKGROUND AND AIMS

Practice-based research holds potential as a promising solution to closing the research-practice gap, because it addresses research questions based on problems that arise in clinical practice and tests whether systems and interventions are effective and sustainable in a clinical setting. One type of practice-based research involves capturing practice by collecting evidence within clinical settings to evaluate the effectiveness of current practices. Here, we describe our collaboration between researchers and clinicians that sought to answer clinician-driven questions about community-based language interventions for young children (Are our interventions effective? What predicts response to our interventions?) and to address questions about the characteristics, strengths, and challenges of engaging in practice-based research.

METHODS

We performed a retrospective chart review of 59 young children who had participated in three group language interventions at one publicly funded community clinic between 2012 and 2017. Change on the Focus on the Outcomes of Communication Under Six (FOCUS), a government mandated communicative participation measure, was extracted as the main outcome measure. Potential predictors of growth during intervention were also extracted from the charts, including type of intervention received, attendance, age at the start of intervention, functional communication ability pre-intervention, and time between pre- and post-intervention FOCUS scores.

RESULTS

Overall, 49% of children demonstrated meaningful clinical change on the FOCUS after their participation in the language groups. Only 3% of participants showed possibly meaningful clinical change, while the remaining 46% of participants demonstrated not likely meaningful clinical change. There were no significant predictors of communicative participation growth during intervention.

CONCLUSIONS

Using a practice-based research approach aimed at capturing current practice, we were able to answer questions about the effectiveness of interventions delivered in real-world settings and learn about factors that do not appear to influence growth during these interventions. We also learned about benefits associated with engaging in practice-based research, including high clinical motivation, high external validity, and minimal time/cost investment. Challenges identified were helpful in informing our future efforts to examine other possible predictors through development of a new, clinically feasible checklist, and to pursue methods for improving collection of outcome data in the clinical setting.Implications: Clinicians and researchers can successfully collaborate to answer clinically informed research questions while considering realistic clinical practice and using research-informed methods and principles. Practice-based research partnerships between researchers and clinicians are both valuable and feasible.

Validity of a streamlined version of the Focus on the Outcomes of Communication Under Six: Process and outcome

BACKGROUND

The Focus on the Outcomes of Communication Under Six (FOCUS) is a 50-item outcome measure based on the framework and concepts of World Health Organization's International Classification of Functioning. The FOCUS has been shown to capture participation-level changes associated with speech and language therapy in children 18 to 72 months old and has established validity and reliability. However, there were reasons to try to reduce the measure without losing any of its proven value as a change-detecting instrument.

METHODS

Using data from 18,931 preschool children, we used item response models and a test of redundancy to reduce the original 50-item FOCUS to 34 items. We then assessed the correlations between FOCUS-50 and FOCUS-34 scores on these children.

RESULTS

Findings show that a shortened (34-item) version of FOCUS can be treated as equivalent to the full 50-item version.

CONCLUSION

The correlation between change scores on the two versions is .98. We suggest that in situations where only a total score is of interest, the FOCUS-34 can be used in place of the full FOCUS.

Stability of the Gross Motor Function Classification System, Manual Ability Classification System, and Communication Function Classification System

AIM

To determine the stability of the Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS) over 1-year and 2-year intervals using a process for consensus classification between parents and therapists.

METHOD

Participants were 664 children with cerebral palsy (CP), 18 months to 12 years of age, one of their parents, and 90 therapists. Consensus between parents and therapists on level of function was ≥92% for the GMFCS, MACS, and CFCS. A linearly weighted kappa coefficient of ≥0.75 was the criterion for stability.

RESULTS

Kappa coefficients varied from 0.76 to 0.88 for the GMFCS, 0.59 to 0.73 for the MACS, and 0.57 to 0.77 for the CFCS. For children younger than 4 years of age, level of function did not change for 58.2% on the GMFCS, 30.3% on the MACS, and 39.3% on the CFCS. For children 4 years of age or older, level of function did not change for 72.3% on the GMFCS, 49.1% on the MACS, and 55% on the CFCS.

INTERPRETATION

The findings support repeated classification of children over time. The kappa coefficients for the GMFCS are attributed to descriptions of levels for each age band. Consensus classification facilitates discussion between parents and professionals that has implications for shared decision-making.

WHAT THIS PAPER ADDS

The findings support repeated classification of children over time. Stability was higher for the Gross Motor Function Classification System than the Manual Ability Classification System and Communication Function Classification System. The function of younger children was more likely to be reclassified. Percentage agreement between parents and therapists using consensus classification varied from 92% to 97%. The intraclass correlation coefficient overestimated stability compared with the weighted kappa coefficient.

The Effectiveness of Parental Questionnaires in the Assessment of Speech-Language and Auditory Function in Children

OBJECTIVE

This study investigates the use of a parental questionnaire to determine its effectiveness as a screening tool in identifying speech-language and/or auditory impairments in children.

PATIENTS AND METHODS

Parents completed speech-language (n = 36) or audiology (n = 23) questionnaires prior to their child's speech-language and/or auditory evaluations. The speech-language and audiology evaluations were conducted by clinicians at three different universities not familiar with the administration and scoring of the parental questionnaires. A research assistant coded the results of the speech-language and audiology evaluations. Statistical analysis was used to determine if any aspects of the parents' evaluation of their child's speech, language, or hearing correlated with the speech-language pathologists'/audiologists' assessment. The results of the analyses would indicate whether parental reports are a reliable alternative to professionals' assessment.

RESULTS

The speech-language questionnaires for children aged 2-5 years revealed the parents' perception of their children speaking 3-word sentences significantly (p < 0.05) corresponded to the children's comprehension and expression skills. The results from the auditory questionnaires revealed that reports of a child's ear pain were (p < 0.05) correlated with auditory dysfunction.

CONCLUSIONS

These questionnaires can potentially be used in low-income countries where professional resources are scarce and there are barriers to identifying children with speech-language and/or auditory impairment.

Factors Contributing to Preschoolers' Communicative Participation Outcomes: Findings From a Population-Based Longitudinal Cohort Study in Ontario, Canada

PURPOSE

The aim of this study was to identify predictors of communicative participation outcomes for a large cohort of preschoolers with speech and language impairments.

METHOD

A secondary analysis of longitudinal program evaluation data from Ontario, Canada's Preschool Speech and Language Program was done. Data available for 46,872 children 18-67 months of age (M = 41.76 months, SD = 11.92; 68% boys, 32% girls) were previously used to predict children's communicative participation skill development in 5 levels of function. Demographic and intervention-based variables were added to the models to identify new predictors of growth.

RESULTS

Three demographic and 3 intervention-based variables were statistically significant predictors of children's communicative participation outcomes. Clinically significant predictors included participation in an early learning environment, receipt of speech-language interventions, and the amount of time spent in intervention. These variables impacted predicted outcomes differently, depending on a child's level of communicative function.

CONCLUSIONS

This population-based study of preschoolers with speech and language impairments identified predictors of growth in communicative participation skills-an outcome important and meaningful to families but not often explored. A broad picture emerged of factors that may influence the development of communicative participation skills and may be used to predict outcomes for preschoolers. Given the large sample size, these robust findings may be used to predict outcomes outside the Preschool Speech and Language Program as well.

A population-based study of communicative participation in preschool children with speech-language impairments

AIM

To develop statistical models of communicative participation development of preschool children and explore variations by level of function.

METHOD

This was a secondary analysis of data from a longitudinal study of preschool children with speech and language impairments (n=46 872; age range 18-67mo, mean age [SD] 41.76mo [11.92]; 67% male) accessing publicly funded services in Ontario, Canada. Two measures were used: Focus on the Outcomes of Communication Under Six (FOCUS), measuring changes in communicative participation skills, and the Communication Function Classification System (CFCS), classifying communicative function into one of five levels. We used mixed effects modeling to fit growth curves for children in each CFCS level. Models allowed for variation in initial FOCUS score at 18 months, rate of growth with age, and rate of acceleration/deceleration with age.

RESULTS

Starting FOCUS score (18mo) varied inversely with CFCS level at entry to the program. Growth was initially rapid and then leveled off for children in Levels I to III. Growth was less rapid for children in Level IV, but leveled off, and was slow but continual for children in Level V.

INTERPRETATION

This work can help us to move beyond traditional impairment-based thinking and shows that children can make meaningful communicative changes regardless of their function.
