“…We excluded articles for the following reasons: (a) being a duplicate article (in Google Scholar and Pubmed); (b) being a review or theory article (which we scanned for relevant references); and (c) not an intervention that examines the direct link between a mindfulness intervention and impulsivity. More specifically, we excluded studies that investigated (a) mindfulness or impulsivity as a mediator or moderator of other variables (e.g., Vinci et al, 2016, examined the mediating role of impulsivity and mindfulness on the relation between mindfulness training and sexual risk); (b) mindfulness interventions used in conjunction with another well-defined treatment protocol (e.g., Schoenberg et al, 2014, utilized Mindfulness-based stress reduction; Yao et al, 2017, combined mindfulness with reality therapy); (c) an intervention labeled as mindfulness inappropriately (only studies that clearly justified their intervention as mindfulness were included) (e.g., Green et al, 2018, implemented biofeedback training, which arguably involves more introspective awareness than mindfulness); and (d) impulsive behaviors or urges secondary to addiction that did not include an appropriate measure and operationalization of impulsivity (e.g., Marcowski et al, 2017, used urges to smoke to index impulsivity, although urges do not necessarily indicate impulsivity or impulsive behavior). Conner and White (2018) used a well-known measure of emotion regulation to index impulsivity.…”
