“…It is interesting to note that while interviews were the main strategy to listen to children's voices, we found a great variation in their use with regards to conditions, circumstances and material used to elicit children's views. For instance, we found reasonable evidence that interviews were conducted with the help of pictures and images (Baird and Grace, 2017;Baker, Tisak and Tisak, 2016;Cheng Pui-Wah Reunamo, Cooper, Liu and Vong, 2015;Correia and Aguiar, 2017;Li, 2016;Penderi and Rekalidou, 2016), hypothetical situations (Cheng Pui-Wah et al, 2015;Reunamo et al, 2015), with photos children took (Adderley et al, 2015;McEvilly, 2015;Wahle et al, 2017;White, 2015), using dolls (Baird and Grace, 2017;Correia and Aguiar, 2017;Koller and San Juan, 2015;White, 2016), having children drawing while being interviewed (Fleer and Li, 2016) or by using children's drawings (Adderley et al, 2015;Katz and McLeigh, 2017;Leigh, 2015;Wahle et al, 2017). However, there was less emphasis in the use of the "draw and tell" method (Fluckiger, Dunn and Stinson, 2018;O'Rourke et al, 2017;Wahle et al, 2017;Wong, 2015), play-based interviews (Koller and San Juan, 2015), and interviews including a story-telling (Gunnestad, Mørreaunet and Onyango, 2015).…”
