BACKGROUND: Stroke and other acquired brain injuries (ABIs) can present challenging experiences for individuals, both in recovery of functions affected by visible or invisible impairments and in learning to live with the new situation. Research has shown that sharing experiences face-to-face in peer groups can be beneficial during recovery. However, there is limited knowledge about the lived experiences of people with ABI who participate in online peer-to-peer groups.

OBJECTIVE: The aim of our study was to explore the lived experiences of participating in online peer-to-peer groups for people with ABI, where participants themselves set the agenda.

METHODS: Members of 2 Facebook groups (FBGs) for people with ABI were invited to participate in this study, and 20 individuals were included (14 women and 6 men; age range 24-74 years). One FBG focused on stroke and the other on fatigue caused by ABI. One group was private, and the other group was public. Data were collected through semistructured interviews, in which participants were encouraged to describe their experiences of engaging in FBGs in detail. The interviews were conducted over telephone or Zoom and digitally recorded. The audio recordings were then transcribed verbatim, resulting in 224 pages of text, and analyzed using the empirical phenomenological psychological method.

RESULTS: The analysis presented a common meaning structure with 1 main characteristic that is, "validating self," common for all 20 participants, and 3 subcharacteristics, that is, "learning-having one's own experiences confirmed," "adjusting self-building competence and self-compassion," and "supporting others-becoming a valued lived-experience expert/authority." Together, the subcharacteristics reflected a process of validating self from newcomer to lived-experience expert or authority. In this process, members of FBGs moved from being newcomers with pronounced needs for support and to learn and to have their experiences confirmed by others with similar experiences. Thus, participants were building competence and developing self-compassion. Gradually, they assumed the role of advisors, mentors, or coaches, acknowledging their experiences and competence as valuable to others, thereby validating themselves as compassionate lived-experience experts or authorities in supporting others.

CONCLUSIONS: Participation in online peer-to-peer groups can offer unique opportunities for individuals with ABI to validate self through processes that involve learning, developing self-compassion and compassion for others, and offering support to others with similar experiences. Given that rehabilitation after an ABI is often of limited duration and that positive experiences can be achieved over time through involvement in digital peer-to-peer support, health care professionals should assist patients by providing information and directing them to digital networks for people with ABI. However, when recommending the use of online peer-to-peer support, impairments and insufficient digital competence that may complicate or prevent the use of social media should be assessed and support provided when relevant.
