Objectives Suicide is the fourth leading cause of death for individuals aged 15–29 years, and early intervention on suicidal ideation and risk factors should be priortized. Brief mindfulness meditation (BMM) is convenient and cost-effective in improving physical and mental well-being, but less is known about its efficacy for suicidal ideation, stress and sleep quality. We investigated the effects of BMM on suicidal ideation, stress, and sleep quality for individuals with suicide risk. Methods Sixty-four college students with high suicidal ideation (aged 18–30 years) were randomly allocated to either a BMM (n = 32) or control group (n = 32). The BMM was based on Anapanasati and core mindfulness concepts. Sixty participants completed all scheduled sessions including pretest, one month of intervention or waiting, and posttest. Suicidal ideation was measured with the Beck Scale for Suicidal Ideation. Stress was evaluated using the Perceived Stress Scale and salivary cortisol levels. Sleep was measured using the Pittsburgh Sleep Quality Index and actigraphy accompanied with 7-day sleep diaries. Results Post-intervention, the BMM group showed significant decrease in suicidal ideation with a large effect size; the decrease showed a medium effect size in the control group. The BMM group, but not the control group, showed significant decrease in morning salivary cortisol and sleep latency, and improved sleep efficiency. Conclusions BMM could help reduce suicidal ideation, stress, and sleep disturbance for individuals with high suicidal ideation and it may implicate effective suicide prevention strategy.
