Adapting a Psychosocial Support Intervention for the Rett Syndrome Community

Overview

This study seeks to adapt Caregiver Speaks, a psychosocial supportive intervention delivered through Facebook, for parent caregivers of children living with Rett Syndrome. This study also seeks to explore feasibility and acceptability of implementing the adapted intervention, and its impact on parent psychological outcomes.

Rett syndrome (RTT) is a rare, progressive neurodevelopmental disorder characterized by early developmental regression, severe intellectual and physical disability, seizures, feeding and breathing abnormalities, and a markedly reduced lifespan. These complex medical needs require intensive, lifelong caregiving, most often provided by parents. As a result, RTT profoundly affects not only the child but the entire family system. Parent caregivers must navigate highly specialized healthcare systems while simultaneously providing continuous, around-the-clock care and managing significant emotional strain. The diagnosis of RTT is frequently described as devastating for parents, who experience anticipatory grief, anxiety, parenting stress, and chronic distress as caregiving demands escalate across the lifespan. Making sense of the diagnosis-including the possibility of early death-can be especially challenging, as it contradicts deeply held expectations that parents will outlive their children. Research in RTT and other rare pediatric conditions demonstrates that caregiver psychological distress is strongly linked to caregiving burden, treatment adherence, and child quality of life, highlighting the inseparability of patient and family wellbeing. Despite this, RTT care has historically focused almost exclusively on medical management, with limited availability of evidence-based psychosocial interventions tailored to the unique emotional and social experiences of RTT caregivers. There is a critical need for innovative, scalable approaches that support caregiver wellbeing, reduce isolation, and integrate meaning-centered psychosocial care alongside pharmacologic treatment. Overview of the Intervention This project centers on adapting and evaluating Caregiver Speaks, a meaning-centered, storytelling-based psychosocial intervention originally developed for family caregivers of individuals with dementia and cancer. Caregiver Speaks is grounded in Park and Folkman's meaning-making model of stress and coping, which posits that individuals adapt to stressful life events by reconstructing and integrating new meaning into their personal narratives. The intervention uses guided photo-elicitation and moderated online group discussion to help caregivers reflect on their caregiving experiences, reframe sources of distress, and build emotional connection with peers facing similar challenges. Prior studies demonstrate that Caregiver Speaks improves caregiver psychological outcomes by reducing stress and grief intensity while enhancing meaning, purpose, and social support. However, Caregiver Speaks has never been adapted for caregivers of children with life-limiting neurodevelopmental conditions such as RTT. Preliminary research with RTT families indicates that the intervention requires significant adaptation to address the medical complexity, prolonged caregiving trajectory, and profound social isolation experienced by RTT caregivers. This study represents the first effort to optimize Caregiver Speaks for the RTT community and integrate it with emerging pharmacologic treatments. Study Objectives and Aims The overarching goal of this project is to enhance whole-family wellbeing in RTT by developing, piloting, and preliminarily evaluating Caregiver Speaks-RTT, an adapted version of the intervention designed specifically for caregivers of individuals with RTT. Aim 1: Adapt the Caregiver Speaks intervention for RTT caregivers using Rapid Community Translation (RCT) methodology. Parents of children with RTT and clinicians from RTT Centers of Excellence (CoE) will collaboratively refine intervention content, format, and delivery to ensure relevance, acceptability, and clinical feasibility while preserving the intervention's core components. Aim 2: Evaluate the feasibility and acceptability of Caregiver Speaks-RTT through a single-arm, mixed-methods pilot study. Two sequential cohorts of caregivers will participate in the 6-week online intervention, allowing for iterative refinement between cohorts. Quantitative and qualitative data will assess feasibility, engagement, retention, and caregiver perceptions of acceptability and appropriateness. Aim 3: Conduct an exploratory randomized comparative study to examine caregiver outcomes when Caregiver Speaks-RTT is integrated with pharmacologic treatment. Caregivers will be randomized to receive either pharmacologic treatment alone or pharmacologic treatment plus Caregiver Speaks-RTT, allowing for preliminary exploration of additive benefits to caregiver wellbeing, family functioning, and medication adherence. Study Design and Methods This is a multi-phase, mixed-methods study conducted over two years. Aim 1: Rapid Community Translation (Adaptation Phase) A working group of approximately 10 participants-including RTT caregivers and CoE clinicians-will engage in a series of structured, virtual sessions facilitated by an interdisciplinary research team with expertise in social work, psychology, neurology, rare disease research, and qualitative methods. Sessions will include education on caregiver distress in RTT, discussion of meaning-making and social support, and hands-on review of Caregiver Speaks materials. Participant feedback will guide systematic adaptations to ensure cultural relevance, clarity, and feasibility for RTT families and clinical care environments. Aim 2: Feasibility and Acceptability Pilot Twenty caregivers of individuals with RTT will participate in two cohorts of the adapted Caregiver Speaks-RTT intervention. Each cohort will engage in a 6-week, asynchronous, moderated private Facebook group. Caregivers will share photos and stories reflecting their caregiving experiences, respond to weekly prompts, and engage with peers. Feasibility will be assessed through recruitment, retention, session participation, and completeness of outcome data. Acceptability and appropriateness will be evaluated using validated surveys and post-intervention qualitative interviews. Interviews will also explore caregivers' experiences with medication adherence, including perceived barriers and facilitators, to inform integrated care strategies. Aim 3: Exploratory Comparative Trial Thirty caregivers will be randomized into two groups: pharmacologic treatment plus Caregiver Speaks-RTT, or pharmacologic treatment alone (with delayed access to the intervention). Outcomes will be measured at baseline and post-intervention using validated scales assessing caregiver mental health, caregiving burden, parenting stress, meaning and purpose, social isolation, medication barriers, and child quality of life. Although not powered for efficacy, this exploratory analysis will generate critical proof-of-concept data. Data Analysis Quantitative data will be analyzed using descriptive statistics and exploratory comparisons to examine feasibility benchmarks, acceptability thresholds, and pre-post changes in outcomes. Qualitative interview data will be analyzed using grounded theory and convergent mixed-methods approaches to contextualize quantitative findings and identify mechanisms of change. Adaptations will be documented using established reporting frameworks to support reproducibility and future dissemination. Ethical Considerations This study involves minimal risk. Participation may evoke emotional responses related to sensitive caregiving experiences; all intervention activities are optional, and participants may withdraw at any time. Confidentiality is protected through secure data systems, private online groups, and de-identification procedures. All procedures are reviewed and approved by the Colorado Multiple Institutional Review Board. Impact and Future Directions This study will generate critical preliminary evidence for an innovative, integrated model of care that addresses both the medical and psychosocial needs of families affected by RTT. By supporting caregiver meaning-making, reducing distress, and strengthening peer support, Caregiver Speaks-RTT has the potential to improve family functioning, enhance treatment adherence, and positively influence child quality of life. Findings will directly inform a future, fully powered NIH-funded clinical trial and guide broader implementation of Caregiver Speaks-RTT across RTT Centers of Excellence. More broadly, this work establishes a scalable framework for integrating psychosocial support with pharmacologic treatment in rare pediatric disorders, advancing whole-family care and community health.
