Experimental effects of mindfulness inductions on self-regulation: Systematic review and meta-analysis.

Abstract

Self-regulation is the control of aspects of the self to allow pursuit of long-term goals, and it is proposed as a central pathway through which mindfulness may exert benefits on well-being. However, the effects of a single mindfulness induction on self-regulation are not clear, as there has been no comprehensive review of this evidence. The current review synthesized existing findings relating to the effect of a mindfulness induction delivered in a laboratory setting on measures of self-regulation. Twenty-seven studies were included and grouped according to 3 outcomes: regulation of experimentally induced negative affect (k = 15; meta-analysis), emotion-regulation strategies (k = 7) and executive functions (k = 9; narrative synthesis). A mindfulness induction was superior to comparison groups in enhancing the regulation of negative affect (d = -.28). Executive-function performance was enhanced only when the experimental design included an affect induction or when the outcome was sustained attention. The effect on emotion-regulation strategies was inconclusive, but with emerging evidence for an effect on rumination. Overall, the findings indicate that, in the form of an induction, mindfulness may have the most immediate effect on attention mechanisms rather than exerting cognitive changes in other domains, as are often reported outcomes of longer mindfulness training. Through effecting change in attention, emotion regulation of negative affect can be enhanced, and subsequently, executive-function performance more quickly restored. The interpretations of the findings are caveated with consideration of the low quality of many of the included study designs determined by the quality appraisal tool. (PsycINFO Database Record

Dispositional Mindfulness and Attentional Control: The Specific Association Between the Mindfulness Facets of Non-judgment and Describing With Flexibility of Early Operating Orienting in Conflict Detection

“…This flexible orienting makes it easier to disengage from salient stimuli/information that is irrelevant for goal-directed behavior. This positive effect of mindfulness on attention orienting was, similarly, reported in a recent meta-analysis of mindfulness induction in laboratory settings ( Leyland et al, 2018 ). It was the FFMQ facets Describing and Non-Judgment that specifically predicted this flexibility of the orienting attention network, which facilitated an efficiency of the flanker incongruent conflict detection.…”

Mindfulness-Based Programs in the Workplace: a Meta-Analysis of Randomized Controlled Trials

“…Hours of attendance on the other hand was significantly associated with higher improvements in mindfulness, well-being/life satisfaction and reduction of burnout symptoms, supporting the theoretical assumption that mindfulness requires a certain amount of practice (e.g., Bishop et al 2004;Tang et al 2015). Laboratory studies have suggested positive short-term effects of mindfulness inductions (Leyland et al 2018). However, how much minimum training is required to yield sustainable effects remains uncertain.…”

Psychological Well-being and Coping: the Predictive Value of Adult Attachment, Dispositional Mindfulness, and Emotion Regulation

“…Future research may wish to continue utilizing experimental design and behavioral indicators to successfully compliment the current self-report measures of mindfulness to further examine the relationships between constructs (see Arch and Craske 2006;Keng et al 2017;Watford and Stafford 2015). A recent meta-analysis of mindfulness and emotion regulation showcases methodological developments in this research field, and confirms the relationship between these constructs through experimental manipulation (Leyland et al 2018). Within the context of refinement and measurement, the present study aimed to further our understanding of coping and its relationship to the measured constructs by utilizing an alternative scoring of the BriefCOPE (Carver 1997) to produce two contrasting subscales (activity and defeatism; Mohr et al 2014).…”
