Spoken Vocabulary Outcomes of Toddlers With Developmental Delay After Parent-Implemented Augmented Language Intervention

Augmentative and Alternative Communication Services During the COVID-19 Pandemic: Contextual Determinants of the Parent-Speech-Language Pathologist Partnership

PURPOSE

The COVID-19 pandemic caused significant changes for family-professional interactions. Many services shifted to telepractice, with new opportunities for parents and speech-language pathologists (SLPs) to partner for service delivery. Parent-coached models of augmentative and alternative communication (AAC) intervention provide positive outcomes for children; however, SLPs have reported difficulty building strong partnerships with families. The shift to telepractice during the COVID-19 pandemic provided a unique context to examine factors influencing parent-SLP partnerships, particularly for parents with children who use aided AAC.

METHOD

Twenty-five parents and 25 SLPs who engaged in services with children and youth from 3 to 21 years of age who used aided AAC during the initial stages of the COVID-19 pandemic in June 2020 participated. Semistructured interviews were conducted individually with parents and SLPs to understand perspectives on whether the change in service delivery facilitated or hindered family-oriented practice. Inductive qualitative analysis was used to analyze information about the factors impacting parent-SLP partnerships.

RESULTS

The parent-SLP partnership was influenced by setting and systemic determinants, and intrinsic determinants to the parent and the SLP that included their history and rapport, beliefs about partnering, and knowledge and skills. These determinants served as barriers or facilitators to their partnership.

CONCLUSIONS

It is essential to consider the relationship, expectations, and knowledge and skills that SLPs and parents bring to the partnership, along with extrinsic structural factors that can impact this partnership. Positive rapport, valued partnership, and an openness to sharing knowledge through teaming and collaboration provided for positive parent-SLP partnerships.

A scoping review of communication outcomes measures in augmentative and alternative communication

Although outcomes are a critical component of evidence-based practice, measuring augmentative and alternative communication (AAC) outcomes remains problematic. This is, in part, because there is no consensus on how to operationally define AAC communication outcomes. To gain greater insight into AAC communication outcomes, we used the communicative competence framework to determine which areas of AAC intervention have received the greatest attention and how these outcomes are being measured. The following data were charted from the 77 studies that met the inclusion criteria for the scoping review: study design, study participants, study communication target (e.g., language, word learning, etc.), and communication outcome measurements. Across the included studies, researchers used a variety of standardized and non-standardized measures to assess outcomes. Seventy-seven percent of the studies assessed social skills and 62% assessed linguistic skills. A limited number of studies measured operational (14%), strategic (4%), and psychosocial (18%) skills. Using the communicative competence framework enabled us to identify gaps in the research that has been conducted to date.

CDK13-related disorder: a deep characterization of speech and language abilities and addition of 33 novel cases

Speech and language impairments are central features of CDK13-related disorder. While pathogenic CDK13 variants have been associated with childhood apraxia of speech (CAS), a systematic characterisation of communication has not been conducted. Here we examined speech, language, non-verbal communication skills, social behaviour and health and development in 41 individuals with CDK13-related disorder from 10 countries (male = 22, median-age 7 years 1 month, range 1-25 years; 33 novel). Most participants used augmentative and alternative communication (AAC) in early childhood (24/41). CAS was common (14/22). Performance varied widely across intellectual ability, social behaviour and expressive language skills, with participants ranging from within average through to the severely impaired range. Receptive language was significantly stronger than expressive language ability. Social motivation was a relative strength. In terms of a broader health phenotype, a quarter had one or more of: renal, urogenital, musculoskeletal, and cardiac malformations, vision impairment, ear infections and/or sleep disturbance. All had gross and fine motor impairments (41/41). Other conditions included mild-moderate intellectual disability (16/22) and autism (7/41). No genotype-phenotype correlations were found. Recognition of CAS, a rare speech disorder, is required to ensure appropriately targeted therapy. The high prevalence of speech and language impairment underscores the importance of tailored speech therapy, particularly early access to AAC supports.

It's Never Too Late: Debunking Myths About Communication and Adults With Severe Disabilities

Communication infuses all dimensions and stages of life, influencing one's self-determination and quality of life. A number of empirical studies have demonstrated that people with severe disabilities continue to develop communication and language skills well into their adult years and make measurable gains when provided with appropriate communication services and supports. Several myths about age, ability, and experiences limit opportunities for persons with severe disabilities. In this paper, we confront and address these myths.

Spoken Vocabulary Outcomes of Toddlers With Developmental Delay After Parent-Implemented Augmented Language Intervention

Purpose Early intervention using augmentative and alternative communication (AAC) supports both receptive and expressive language skills. However, many parents and clinicians still worry that augmented language intervention might delay or impair speech development. This study aimed to (a) characterize and analyze the speech sound development of toddlers with developmental delay who participated in a parent-implemented language intervention; (b) examine the accuracy of speech sounds among toddlers who participated in an augmented language intervention using speech-generating devices and toddlers who participated in a traditional, spoken language intervention; and (c) examine the relationship between baseline factors (i.e., receptive and expressive language skills, vocal imitation, and number of unintelligible utterances) and the number of spoken target vocabulary words after intervention. Method This study used extant data from two randomized control trials of parent-implemented language interventions using AAC or spoken language. Out of 109 children who completed the intervention, 45 children produced spoken target vocabulary words at the end of the intervention. We identified and phonetically transcribed spoken target vocabulary words for each child and then classified them based on Shriberg and Kwiatkowski's (1982) developmental sound classes. Results Children's speech sound accuracy was not significantly different across intervention groups. Overall, children who produced more words had more speech sound errors and higher baseline language scores. Intervention group and baseline receptive and expressive language skills significantly predicted the number of spoken target vocabulary words produced at the end of intervention. Conclusions Participation in AAC intervention resulted in significantly more spoken target vocabulary words and no statistically significant differences in speech sound errors when compared to children who received spoken language intervention without AAC. Results support using AAC interventions for very young children without the fear that it will delay speech or spoken language development. Supplemental Material https://doi.org/10.23641/asha.14265365.
