“…A different intervention was explored in each study, with the exception of the PEGS programme, which was evaluated both in a stand‐alone efficacy trial (Newgent, Behrend, Lounsbery et al, 2010) and in comparison with the efficacy of the ARK (Newgent, Higgins, Belk et al, 2011). The interventions focused on a range of skills such as interpreting intentionality of behaviours and social cues (Graham, Taylor and Hudley, 2015), social problem‐solving skills (Berner, Fee and Turner, 2001; Maddern, Franey, McLaughlin et al, 2004; Newgent, Behrend, Lounsbery et al, 2010; Newgent, Higgins, Belk et al, 2011), cooperation (Baker, Parks‐Savage and Rehfuss, 2009; Lane, Wehby, Menzies et al, 2003; Maddern, Franey, McLaughlin et al, 2004; Newgent, Behrend, Lounsbery et al, 2010), assertiveness (Baker, Parks‐Savage and Rehfuss, 2009; Lane, Wehby, Menzies et al, 2003; Newgent, Behrend, Lounsbery et al, 2010; Newgent, Higgins, Belk et al, 2011), self‐esteem (Newgent, Behrend, Lounsbery et al, 2010; Newgent, Higgins, Belk et al, 2011), empathy (Baker, Parks‐Savage and Rehfuss, 2009; Knowler and Frederickson, 2013; Lane, Wehby, Menzies et al, 2003), self‐control (Baker, Parks‐Savage and Rehfuss, 2009; Lane, Wehby, Menzies et al, 2003), confidence and self‐efficacy (Humphrey, Kalambouka, Wigelsworth et al, 2010b) and self‐awareness and self‐regulation skills (Humphrey, Kalambouka, Wigelsworth et al, 2010a; Humphrey, Kalambouka, Wigelsworth et al, 2010b; Knowler and Frederickson, 2013; Maddern, Franey, McLaughlin et al, 2004).…”
