“…Four studies used a mixed‐methods design: Salomon, Frankel, Chuang, Eti, and Selwyn (), Nakagawa, Yuzefpolskaya, Colombo, Naka, and Blinderman (), Metzger, Song, Ward, et al () and Metzger Song, and Devane‐Johnson (), Swetz, Freeman, et al (). Metzger, Song, Ward, et al, ; Metzger, Song, & Devane‐Johnson, was published in two parts, separately reporting the results of a randomised controlled trial and a qualitative study. However, here it is reviewed as a single mixed method study, because data for both parts were collected from the same participants during interviews.…”
