“…The 52 included articles utilised quantitative surveys to collect data, which were either self-completed by participants (n = 17) [36,39,40,45,51,55,57,60,63,66,68,70,76,80,81,83,84], conducted as face-to-face interviews (n = 34) [34, 35, 37, 38, 41-44, 46-50, 52-54, 56, 58, 61, 62, 64, 65, 67, 69, 71-75, 77-79, 82, 85], or over the phone (n = 1) [59]. Interventional articles were more likely to detail the employment of face-to-face interview techniques compared to the other modalities (n = 15 face-to-face, n = 4 self-complete, n = 0 phone), as were observational articles (n = 19 face-to-face, n = 13 self-complete, n = 1 phone).…”
