“…Although not consistently reported, a range of study designs and methodologies were employed, including participatory action research (n = 3) [75,89,92], ethnography (n = 3) [81,84,85], formative, process, or outcome evaluations (n = 3) [78,93,96], phenomenology (n = 3) [77,90,91], qualitative descriptive (n = 2) [87,99], explorative (n = 2) [76,95], case study (n = 2) [86,88], and field study (n = 1) [94] designs. The most common method for eliciting participant perspectives were interviews (n = 17) [76-78, 80, 81, 83-86, 90-93, 95-97, 99], while four studies conducted focus groups [75,88,89,94], and four used questionnaires [79,82,87,98]. Additionally, over half the studies (n = 14) employed more than one data collection method, such as playground observations in combination with interviews or focus groups.…”
