Abstract
Objectives
Many cognitive changes occur in later life, including declines in attentional control and executive functioning. These cognitive domains appear to be enhanced with mindfulness training, particularly focused attention mindfulness (FAM) meditation, suggesting this practice might slow age-related change. We hypothesized that FAM training would increase self-reported and behaviorally measured mindfulness; improve executive functioning, attentional control, and emotion regulation; and reduce self-reported daily cognitive errors in older adults. To address the call for higher methodological rigor in the field, we used a RCT design with an active control group, measured credibility and expectancy, used objective measures, and attempted to isolate mechanisms of action of mindfulness.
Methods
Fifty older adults aged 65 to 90 (M = 75.7, SD = 5.7) completed pre-training testing followed by 6 weeks of online daily FAM or mind-wandering (control) training and then returned for post-training testing.
Results
Conditions were comparable with respect to credibility and expectancy. However, most hypotheses were not supported. Though aspects of mindfulness, Fs(1,45) ≥ 7.42, ps ≤ .009, ηp2s ≥ 0.13, CIs90% = [0.02, 0.37] and inhibitory control, F(1,43) = 4.95, p = .031, ηp2 = 0.10, CI90% = [0.01, 0.25], increased, this was not specific to mindfulness training. There was modest evidence of an improvement in attentional control specific to the mindfulness group, F(1,43) = 4.59, p = .038, ηp2 = 0.10, CI90% = [0.01, 0.24], but this was not consistent across our two measures.
Conclusions
Results are encouraging for the continued study of mindfulness for improving aspects of attentional control in older adults. However, the present research requires replication in a larger, more diverse sample. Implications for future mindfulness studies with older adults are discussed.
