Objectives: To explore the feasibility and efficacy of web-based mindfulness training for carers of people with spinal cord injury (SCI).; Design: Randomized controlled feasibility study with 3-month follow-up.; Setting: Community setting.; Participants: Spouses or family caregivers (N=55) of people with SCI and chronic neuropathic pain were recruited via the direct care team and advertisements. Participants were older than 18 years (no upper age limit), with Internet access for the duration of the study. Participants were randomly allocated to an 8-week online mindfulness training intervention (n=28), or to receive 8 weeks of psychoeducational materials on SCI and chronic pain (n=27).; Interventions: An established web-based, mindfulness training course was delivered over 8 weeks. Participants completed 10 minutes of mindfulness practices, twice per day, 6 days per week, totaling 960 minutes. The control group received a weekly e-mail with psychoeducational materials (based on the established elements) on SCI and pain for 8 weeks.; Main Outcome Measure: Depression severity.; Results: Mindfulness reduced depression severity more than psychoeducation at T2 (mean difference= -.891; 95% confidence interval,-1.48 to -.30) and T3 (mean difference=-1.96; 95% confidence interval, -2.94 to -.97). Mindfulness training also reduced anxiety at T2 (mean difference=-.888; 95% confidence interval, -1.40 to -.38) and T3 (mean difference=-2.44; 95% confidence interval, -3.20 to -1.69).; Conclusions: Results indicate that Internet-delivered mindfulness training offers unique benefits and is viable for caregivers of people with SCI and chronic neuropathic pain. Further work should explore the feasibility of combined education and mindfulness training incorporating both patient and caregiver, for optimum benefit.
