“…Of the 14 studies in this review, seven were located in the discipline of public health [ 27 , 29 , 30 , 31 , 35 , 36 , 38 ], two in medicine [ 33 , 37 ], two in child, youth, and family studies [ 28 , 32 ], one in mental health and addictions [ 34 ], one in psychology [ 18 ], and one in nursing [ 39 ]. The studies were organized into five categories based on their self-identified approaches: nature-based therapies [ 27 , 29 , 30 , 31 , 36 ], forest therapy [ 34 , 35 , 38 ], horticultural therapy [ 33 , 37 , 39 ], wilderness therapy [ 28 , 32 ], and adventure therapy [ 18 ]. Nature-based therapy is defined as “an intervention with the aim to treat, hasten recovery, and/or rehabilitate patients with a disease or ill health, with the fundamental principle that the therapy involves plants, natural materials, and/or outdoor environment[s]” [ 27 ] (p. 372).…”
