“…Five statements were included in the original draft of the ATOP scale to form a “barrier” subscale, including feelings of fear related to animals and other people, as well as concerns about getting lost or hurt. Source literature included qualitative studies with youth (Burns, et al, 2007; Burns, et al, 2007; Goldenberg, et al, 2010) and other existing scales (Bingley & Milligan, 2004; Eastep, et al, 2011; Eastep, et al, 2011; Faber Taylor & Kuo, 2009; Faber Taylor & Kuo, 2009; Thompson, et al, 2008; Thompson, et al, 2008). Initial statements were: (1) I am afraid of getting lost outside in nature, (2) I don’t like playing outside in nature because there are strangers, (3) I am afraid of wild animals or insects outside in nature, (4) I am afraid of getting hurt if I play outside in nature, and (5) I don’t like playing outside in nature because there are people who are doing drugs.…”
