“…While many studies have replicated the original five-factor hierarchical structure (e.g., Christopher et al, 2012;de Bruin et al, 2012;Michalak et al, 2016;Veehof et al, 2011), others have failed to confirm a five-factor hierarchical structure or have identified better fitting alternative models (e.g., Lecuona et al, 2019;Lilja et al, 2011;Morgan et al, 2017;Tran et al, 2013;Van Dam et al, 2012;Williams et al, 2014). Yet others have found critical differences on the FFMQ as a whole or on its subscales between different samples (e.g., Baer et al, 2006;Karl et al, 2020;Van Dam et al, 2009;Williams et al, 2014). Numerous other studies have proposed alterations or short forms necessary for improved model-to-data fit (Bohlmeijer et al, 2011;Tran et al, 2013;Truong et al, 2020;Gu et al, 2016;Medvedev et al, 2017).…”
