A Meta-Analytic Review of Family-Implemented Social and Communication Interventions for Individuals with Developmental Disabilities

Introducing a self-managed early communication resource for parents - A mixed methods feasibility study of the Swedish "ComAlong online"

BACKGROUND

Web-based programmes offer parents of children with communication difficulties promising access to parent-mediated, early interventions. However, empirical evaluations of such programmes are limited. This study focused on parents and used mixed methods to examine the feasibility of ComAlong online.

METHODS

ComAlong online is a Swedish, self-managed web-resource teaching parents supportive strategies to promote child communication. Data of different types were collected from a total of 71 parents: ten individual parent interviews, 21 pre-questionnaires and 10 post-questionnaires, and finally 50 anonymous digital evaluation surveys. Descriptive statistics and deductive qualitative content analysis were used.

RESULTS

Findings indicate that parents perceived improved child communication and own competence after using the ComAlong online. The most valued parts included podcasts with experts and videos of parent-child interaction. Parents reported that the resource was easy to use, but they wanted to have gained access to the resource when the child was younger. Suggestions for changes included adding a chat function with experts, a parent net forum, and the possibility of creating personalised playlists of videos and podcasts. Evaluation of the research process revealed difficulties in recruiting parents from local child healthcare services and parents of children not yet with a diagnosis.

CONCLUSIONS

This study supports the potential for self-managed, web-based resources to disseminate evidence-based parent training for supporting early communication development. Importantly, parents lack individual guidance from experts and contact with other parents. Also, measures need to be made to disseminate the resources within local child healthcare services.

Parental perceptions of social life before and after attending a parent training program for children with complex communication needs: the ComAlong example

Parent training programs aimed at improving language outcomes for children with complex communication needs have predominantly been evaluated on child-centered outcomes and less often on the impact on social life or parental well-being. This study examined parent perceptions of social life before and after ComAlong, a group intervention providing parents with knowledge and training in responsive communication, environmental-milieu teaching strategies and augmentative and alternative communication (AAC). Parents (N = 467) completed questionnaires during the first and last sessions of ComAlong groups held in Sweden 2012 to 2018. Main outcome measure was change in the Social Life Scale from the Family Impact Questionnaire. Associations between this measure and demographic factors of parents and children were analyzed, along with reported change in parents' use of AAC. Pre-post comparisons revealed small significant positive changes in perceived impact of social life following intervention. The magnitude of the positive change was larger among parents of children with non-syndromic diagnoses and parents of children with autism spectrum disorder or attention deficit hyper activity disorder (ADHD). Differences in social life impact was not associated with parents' gender, language proficiency, age, or educational background. In conclusion, communication-focused parent training programs can have a positive impact on social family life and may thereby influence children's participation.

Systematic Review of Variables Related to Instruction in Augmentative and Alternative Communication Implementation: Group and Single-Case Design

PURPOSE

This article provides a systematic review and analysis of group and single-case studies addressing augmentative and alternative communication (AAC) intervention with school-aged persons having autism spectrum disorder (ASD) and/or intellectual/developmental disabilities resulting in complex communication needs (CCNs). Specifically, we examined participant characteristics in group-design studies reporting AAC intervention outcomes and how these compared to those reported in single-case experimental designs (SCEDs). In addition, we compared the status of intervention features reported in group and SCED studies with respect to instructional strategies utilized.

PARTICIPANTS

Participants included school-aged individuals with CCNs who also experienced ASD or ASD with an intellectual delay who utilized aided or unaided AAC.

METHOD

A systematic review using descriptive statistics and effect sizes was implemented.

RESULTS

Findings revealed that participant features such as race, ethnicity, and home language continue to be underreported in both SCED and group-design studies. Participants in SCED investigations more frequently used multiple communication modes when compared to participants in group studies. The status of pivotal skills such as imitation was sparsely reported in both types of studies. With respect to instructional features, group-design studies were more apt to utilize clinical rather than educational or home settings when compared with SCED studies. In addition, SCED studies were more apt to utilize instructional methods that closely adhered to instructional features more typically characterized as being associated with behavioral approaches.

CONCLUSION

The authors discuss future research needs, practice implications, and a more detailed specification of treatment intensity parameters for future research.

What has been done to improve learning for intellectual disability? An umbrella review of published meta-analyses and systematic reviews

BACKGROUND

Intellectual disability (ID) affects 1%-3% of the paediatric population. Currently, there is no consensus as to the most effective strategies for improving the learning skills of children and adolescents with ID. This review aims to systematically gather information regarding interventions to promote and improve learning skills in children/adolescents with ID from previously published systematic reviews and meta-analyses.

METHODS

Systematic search strategies, including appropriate descriptors, were employed on Medline, Cochrane, Scopus, Web of Science, Lilacs, SciELO, ERIC, and PsycINFO databases. Quality assessment was conducted via the AMSTAR-2.

RESULTS

Fifty-nine studies were selected, subdivided by outcome domains and by the type of intervention. Interventions were related to caregiving, education, pharmaco-dietary, physical, and technology approaches. The overall low quality of the studies limited our recommendations.

Teleintervention for users of augmentative and alternative communication devices: A systematic review

AIM

To synthesize existing evidence on the effectiveness of speech-language teleinterventions delivered via videoconferencing to users of augmentative and alternative communication (AAC) devices.

METHOD

A systematic literature search was conducted in 10 electronic databases, from inception until August 2021. Included were speech-language teleinterventions delivered by researchers and/or clinicians via videoconferencing to users of AAC devices, without restrictions on chronological age and clinical diagnosis. The quality of the studies included in the review was appraised using the Downs and Black checklist and the Single-Case Experimental Design Scale; risk of bias was assessed using the Risk Of Bias In Non-Randomized Studies - of Interventions and the single-case design risk of bias tools.

RESULTS

Six teleinterventions including 25 participants with a variety of conditions, such as Down syndrome, autism, Rett syndrome, and amyotrophic lateral sclerosis met the inclusion criteria. Five studies used a single-case experimental design and one was a cohort study. Teleinterventions included active consultation (n = 2), functional communication training (n = 2), brain-computer interface (n = 1), and both teleintervention and in-person intervention (n = 1). All teleinterventions reported an increase in participants' independent use of AAC devices during the training sessions compared to baseline, as well as an overall high satisfaction and treatment acceptability.

INTERPRETATION

Speech-language teleinterventions for users of AAC devices show great potential for a successful method of service delivery. Future telehealth studies with larger sample sizes and more robust methodology are strongly encouraged to allow the generalization of results across different populations.

WHAT THIS PAPER ADDS

Individuals can learn to use augmentative and alternative communication (AAC) devices independently during tele-AAC interventions. Service providers and recipients reported an overall high satisfaction and acceptability for AAC services delivered via teleinterventions. Speech-language teleinterventions may be an effective method of providing AAC intervention services.

The effect of caregiver-delivered social-communication interventions on skill generalization and maintenance in ASD

BACKGROUND

Although caregiver-delivered social communication interventions have been considered scientifically proven practices for individuals with autism spectrum disorders, it is not well examined if these types of intervention modes are truly effective in promoting skill generalization and maintenance within those individuals with autism spectrum disorders.

AIMS

The purpose of this meta-analysis was to evaluate the status of the extant literature regarding the measures on generalization and/or maintenance of effects of caregiver-delivered communication interventions for children with autism spectrum disorders.

METHODS AND PROCEDURES

This systematic literature review and meta-analysis evaluated peer-reviewed research regarding the effects of caregiver-implemented interventions on the maintenance and generalization of the social-communication skills for children with autism spectrum disorders. A total of 34 articles were included following a systematic search. Articles were summarized according to the following categories: (a) generalization dimension, (b) generalization assessment design, (c) maintenance assessment design, (d) generalization/maintenance teaching strategy, and (e) latency to maintenance probes. After application of design standards, aggregate Tau-U and non-overlap of pairs effect sizes were calculated with a total of 67 separate contrasts across seven studies.

OUTCOMES AND RESULTS

Overall, effect size scores ranged from small to large effects across all comparisons. On average, most of the baseline to maintenance and generalization comparisons produced moderate to large effects. Whereas, small to moderate or even deteriorate effects were found in most of the intervention to maintenance and generalization comparisons.

CONCLUSIONS AND IMPLICATIONS

The findings in this review suggest that caregiver-delivered social-communication interventions are likely to result in mixed effects on skill generalization and maintenance within children with autism spectrum disorders. Implications for future research and practice are discussed.

A meta-analysis of single-case research on the use of tablet-mediated interventions for persons with ASD

BACKGROUND

There is a growing amount of single-case research literature on the benefits of tablet-mediated interventions for individuals with autism spectrum disorder (ASD). With the development of tablet-based computers, tablet-mediated interventions have been widely utilized for education and treatment purposes; however, the overall quality and evidence of this literature-base are unknown.

AIMS

This article aims to present a quality review of the single-case experimental literature and aggregate results across studies involving the use of tablet-mediated interventions for individuals with ASD.

METHODS AND PROCEDURES

Using the Tau nonoverlap effect size measure, the authors extracted data from single-case experimental studies and calculated effect sizes differentiated by moderator variables. The moderator variables included the ages of participants, participants' diagnoses, interventions, outcome measures, settings, and contexts.

OUTCOMES AND RESULTS

Results indicate that tablet-mediated interventions for individuals with ASD have moderate to large effect sizes across the variables evaluated. The majority of research in this review used tablets for video modeling and augmentative and alternative communication.

CONCLUSIONS AND IMPLICATIONS

To promote the usability of tablet-mediated interventions for individuals with ASD, this review indicates that more single-case experimental studies should be conducted with this population in naturalistic home, community, and employment settings.
