Mindfulness meditation improved sleep quality for older adults with moderate sleep disturbance compared with a structured program focused on changing poor sleep habits and establishing a bedtime routine (Black DS et al. JAMA Intern Med. doi:10.1001/jamainternmed.2014.8081 [published online February 16, 2015]).
The trial randomly assigned 24 individuals 55 years and older (average age, 66 years) to a mindful awareness practices (MAPs) intervention and 25 individuals to sleep hygiene education (SHE); both weekly interventions consisted of 2-hour sessions over 6 weeks. All participants had scores exceeding 5 on the Pittsburgh Sleep Quality Index (PSQI), a self-reported questionnaire assessing sleep disturbances, which suggest poor sleep quality associated with adverse health outcomes. Effectiveness of the interventions in improving sleep quality was determined by between-group differences in the PSQI score relative to baseline.
