Diversified caregiver input to upgrade the Young Children's Participation and Environment Measure for equitable pediatric re/habilitation practice.

BACKGROUND: Practitioner and family experiences of pediatric re/habilitation can be inequitable. The Young Children's Participation and Environment Measure (YC-PEM) is an evidence-based and promising electronic patient-reported outcome measure that was designed with and for caregivers for research and practice. This study examined historically minoritized caregivers' responses to revised YC-PEM content modifications and their perspectives on core intelligent virtual agent functionality needed to improve its reach for equitable service design. METHODS: Caregivers were recruited during a routine early intervention (EI) service visit and met five inclusion criteria: (1) were 18 + years old; (2) identified as the parent or legal guardian of a child 0-3 years old enrolled in EI services for 3 + months; (3) read, wrote, and spoke English; (4) had Internet and telephone access; and (5) identified as a parent or legal guardian of a Black, non-Hispanic child or as publicly insured. Three rounds of semi-structured cognitive interviews (55-90 min each) used videoconferencing to gather caregiver feedback on their responses to select content modifications while completing YC-PEM, and their ideas for core intelligent virtual agent functionality. Interviews were transcribed verbatim, cross-checked for accuracy, and deductively and inductively content analyzed by multiple staff in three rounds. RESULTS: Eight Black, non-Hispanic caregivers from a single urban EI catchment and with diverse income levels (Mdn = $15,001-20,000) were enrolled, with children (M = 21.2 months, SD = 7.73) enrolled in EI. Caregivers proposed three ways to improve comprehension (clarify item wording, remove or simplify terms, add item examples). Environmental item edits prompted caregivers to share how they relate and respond to experiences with interpersonal and institutional discrimination impacting participation. Caregivers characterized three core functions of a virtual agent to strengthen YC-PEM navigation (read question aloud, visual and verbal prompts, more examples and/or definitions). CONCLUSIONS: Results indicate four ways that YC-PEM content will be modified to strengthen how providers screen for unmet participation needs and determinants to design pediatric re/habilitation services that are responsive to family priorities. Results also motivate the need for user-centered design of an intelligent virtual agent to strengthen user navigation, prior to undertaking a community-based pragmatic trial of its implementation for equitable practice.

Effectiveness and scalability of an electronic patient-reported outcome measure and decision support tool for family-centred and participation-focused early intervention: PROSPECT hybrid type 1 trial protocol.

INTRODUCTION: Early intervention (EI) endorses family-centred and participation-focused services, but there remain insufficient options for systematically enacting this service approach. The Young Children's Participation and Environment Measure electronic patient-reported outcome (YC-PEM e-PRO) is an evidence-based measure for caregivers that enables family-centred services in EI. The Parent-Reported Outcomes for Strengthening Partnership within the Early Intervention Care Team (PROSPECT) is a community-based pragmatic trial examining the effectiveness of implementing the YC-PEM e-PRO measure and decision support tool as an option for use within routine EI care, on service quality and child outcomes (aim 1). Following trial completion, we will characterise stakeholder perspectives of facilitators and barriers to its implementation across multiple EI programmes (aim 2). METHODS AND ANALYSIS: This study employs a hybrid type 1 effectiveness-implementation study design. For aim 1, we aim to enrol 223 caregivers of children with or at risk for developmental disabilities or delays aged 0-3 years old that have accessed EI services for three or more months from one EI programme in the Denver Metro catchment of Colorado. Participants will be invited to enrol for 12 months, beginning at the time of their child's annual evaluation of progress. Participants will be randomised using a cluster-randomised design at the EI service coordinator level. Both groups will complete baseline testing and follow-up assessment at 1, 6 and 12 months. A generalised linear mixed model will be fitted for each outcome of interest, with group, time and their interactions as primary fixed effects, and adjusting for child age and condition severity as secondary fixed effects. For aim 2, we will conduct focus groups with EI stakeholders (families in the intervention group, service coordinators and other service providers in the EI programme, and programme leadership) which will be analysed thematically to explain aim 1 results and identify supports and remaining barriers to its broader implementation in multiple EI programmes. ETHICS AND DISSEMINATION: This study has been approved by the institutional review boards at the University of Illinois at Chicago (2020-0555) and University of Colorado (20-2380). An active dissemination plan will ensure that findings have maximum reach for research and practice. TRIAL REGISTRATION NUMBER: NCT04562038.

Participation-Focused Strategy Use Among Caregivers of Children Receiving Early Intervention.

IMPORTANCE: Evidence on common types of participation-focused caregiver strategies can help occupational therapy practitioners to take an evidence-based approach to designing participation-focused practice. OBJECTIVE: To identify and explore types of caregiver strategies to support young children's participation in valued occupations in the home and community. DESIGN: Qualitative study using a subset of data collected online with the Young Children's Participation and Environment Measure (YC-PEM). Narrative responses about strategy use were content coded to the family of Participation-Related Constructs (fPRC) framework using a deductive analytic approach to identify relevant types of participation-focused strategies used in the home and community. Responses were further analyzed within each relevant fPRC construct using an inductive analytic approach to identify the scope of strategies used for each construct. SETTING: Early intervention. PARTICIPANTS: Caregivers (N = 106) of young children receiving early intervention. OUTCOMES AND MEASURES: Caregivers' strategies to support their child's home and community participation, provided by the YC-PEM. RESULTS: Caregivers most commonly adapted the child's environment or context to support their child's home and community participation (45.06%). The least common focus of caregiver strategies was the child's activity competencies (11.16%). Three or more types of caregiver strategies were identified for each participation-related construct. CONCLUSION AND RELEVANCE: Results indicated that caregivers used a range of strategies related to each of the participation-related constructs to support their child's participation in home and community occupations, most commonly targeting the environment. Occupational therapy practitioners can select from this range of strategies when planning participation-focused early intervention with families. WHAT THIS ARTICLE ADDS: This study yields new evidence on the scope of caregiver strategy use to support young children's participation in home and community occupations. Occupational therapy practitioners can apply this evidence to anticipate common areas of caregiver strategy use in participation-focused practice with families in early intervention.

Partial FMRP expression is sufficient to normalize neuronal hyperactivity in Fragile X neurons.

Fragile X syndrome (FXS) is the most common genetic form of intellectual disability caused by a CGG repeat expansion in the 5'-UTR of the Fragile X mental retardation gene FMR1, triggering epigenetic silencing and the subsequent absence of the protein, FMRP. Reactivation of FMR1 represents an attractive therapeutic strategy targeting the genetic root cause of FXS. However, largely missing in the FXS field is an understanding of how much FMR1 reactivation is required to rescue FMRP-dependent mutant phenotypes. Here, we utilize FXS patient-derived excitatory neurons to model FXS in vitro and confirm that the absence of FMRP leads to neuronal hyperactivity. We further determined the levels of FMRP and the percentage of FMRP-positive cells necessary to correct this phenotype utilizing a mixed and mosaic neuronal culture system and a combination of CRISPR, antisense and expression technologies to titrate FMRP in FXS and WT neurons. Our data demonstrate that restoration of greater than 5% of overall FMRP expression levels or greater than 20% FMRP-expressing neurons in a mosaic pattern is sufficient to normalize a FMRP-dependent, hyperactive phenotype in FXS iPSC-derived neurons.
