Feasibility of an app-based mindfulness intervention among women with an FMR1 premutation experiencing maternal stress.

BACKGROUND: Women who carry an FMR1 premutation (PM) allele and are mothers of children with fragile X syndrome (FXS) experience elevated maternal stress. In-person mindfulness sessions have been shown to be effective in alleviating maternal stress-related outcomes among mothers of children with intellectual and developmental disabilities. Our prior studies indicate women with a PM are at risk of social anxiety, a potential barrier to in-person mindfulness sessions. AIM: The main goals of this pilot study were to assess feasibility and adherence of an app-based mindfulness training program among mothers of children with FXS and to explore stress, social outcomes, and potential barriers to social support. METHODS: Participants (n = 18) completed questionnaires to assess stress and social anxiety, an app-based mindfulness program, and a semi-structured follow-up interview. RESULTS: Thirteen out of 18 (72%) participants completed the mindfulness program; of those, 10 (77%) found it helpful. Eight out of 18 (44%) participants met criteria for social anxiety and 11 (61%) reported having difficulties reaching out for help when needed. Women with social anxiety and those experiencing barriers to social support were more likely to find the program helpful. CONCLUSIONS: This study provides guidance for future mindfulness-based interventions to alleviate maternal stress in mothers of children with FXS.
