“…Several features regarding the implementation of interventions were also identified by participants as facilitators and barriers. Six implementation features were identified as facilitating the effectiveness of the intervention: group format and process (Daher & Haz, 2011;Horwitz et al, 2017;Kometiani, 2017;Mellor, 2013;Pearce, 2017;van Westrhenen & Fritz, 2012;Zeeman & Lotriet, 2013), supportive and safe climate (Giaver et al, 2017;Mellor, 2013), peer interaction (Baker & Krout, 2012;Mellor, 2013), tailoring (van Westrhenen & Fritz, 2012Zeeman & Lotriet, 2013), spending time outside of routine (Karpavičiūtė & Parkinson, 2015;Pearce, 2017), and other features such as active recruiting efforts (Giaver et al, 2017), modeling (Feagan & Rossiter, 2011), creative methods (Zeeman & Lotriet, 2013), community involvement (Feagan & Rossiter, 2011), and application of knowledge (Zeeman & Lotriet, 2013). On the contrary, three features were identified as barriers to the effectiveness of the intervention: limited time and space (e.g., Giaver et al, 2017;Horwitz et al, 2017;Zeeman & Lotriet, 2013), social barriers (Giaver et al, 2017;Pearce, 2017), and other features such as no-follow-up sessions (Giaver et al, 2017).…”
