Evaluating an online peer support and acceptance and commitment therapy (act) informed intervention for caregivers of adults with asd and learning difficulties: a mixed-methods study

Background: Caregivers of individuals with autism spectrum disorders (ASD) and learning
difficulties (LD) face unique challenges impacting their well-being. This study evaluates an
online Acceptance and Commitment Therapy (ACT)-informed intervention for caregivers of
adults with ASD/LD in Peru.

Objectives: Assess the feasibility, acceptability, adherence, and impact of an online ACT-
informed intervention compared to an online peer support group and a control group.

Methods: A mixed-methods, multiple-baseline experimental design was used. Participants
were assigned to a control condition or one of two intervention conditions: ACT-informed
intervention or peer support group. Both interventions consisted of 8-week, 1-hour weekly
online sessions. The study examined the interventions' impact on mental health and wellbeing,
feasibility, acceptability, adherence, implementation barriers and facilitators, and effects on
adults with ASD/LD.

Results: Preliminary findings indicate positive outcomes for intervention group participants.
Qualitative data suggest improvements in self-care, coping strategies, and tolerance.
Participants reported feeling supported, understood, and less isolated, with some noting
positive changes in relationships with their children. Quantitative analysis and Reflexive
Thematic Analysis are ongoing.
Conclusions: Initial results suggest online ACT-informed interventions and peer support
groups may benefit caregivers of adults with ASD/LD in Peru, highlighting the potential of
technology-based interventions to enhance accessibility and sustainability of caregiver
support. Further analysis will provide more detailed insights into intervention effectiveness and
impact on caregivers and their adult children with ASD/LD.
