“…Few studies, mostly qualitative, suggested increase in cooperative play (Bundy et al, 2008; Kuh et al, 2013; Mahony et al, 2017), and one case study found an increase in group connectedness expressed by decreased sex segregation and increased collaborative opportunities for marginalized children (Heravi et al, 2018). Yet, few quantitative studies found no improvement in indicators such as peer acceptance, social skills, peer group size (Gibson et al, 2017), or group connectedness (Gibson et al, 2018). It has been suggested that the social impact of LPP may be difficult to detect in children with high baseline level of social competence (Bundy et al, 2008) and that children at social risk may potentially benefit more from the intervention, possibly because LPP provides new social opportunities based on capacities such as creativity (Bundy et al, 2008; Gibson et al, 2017).…”
