“…MBIs have been shown to be very beneficial in terms of psychological outcomes (Khoury et al, 2015) on stress (Nyklíček & Kuijpers, 2008;Raab et al, 2015;van Wietmarschen et al, 2018) and negative affectivity, such as anxiety (Antoine, Andreotti, et al, 2018) or depressive states (Goyal et al, 2014). Most studies have shown beneficial effects on negative automatic thoughts (Frewen et al, 2008;Mehdipour et al, 2017) about the world or oneself, selfcriticism (Halamová et al, 2018), rumination, and difficulties with emotional regulation more generally (Brockman et al, 2017;De Vibe et al, 2018;Lindsay et al, 2018). In addition, compared with classic mindfulness interventions, selfhelp programs have shown very similar and important benefits for psychological outcomes (Antoine, Andreotti, et al, 2018;Congard et al, 2019;Halamová et al, 2018;Spijkerman et al, 2016).…”
