冒險遊憩活動本身即存有不確定性，伴隨著某種程度的遊憩者擔憂存在。釐清冒險遊憩活動的擔憂來源，將助於研擬防範因應策略。本研究深度訪談21位陸域與水域冒險遊憩者，經內容分析後歸納出冒險遊憩活動之擔憂來源有「人-環境-管理」三個面向。屬「人」擔憂主要有能力不足、裝備不濟與大意失誤三個因素；「環境」的擔憂則為環境危險與環境適應不良二個因素；「管理」的擔憂乃源自設備養護失當與專業人員失職二個因素。最後，分別從遊憩者與管理者層面提出防範因應策略，供冒險遊憩者在從事活動時之參考，同時亦有助於經營者研擬相關因應作法。

Adventure recreational activities embody elements of uncertainty and are accompanied by certain levels of worry among recreationists. Clarifying the sources of worry over adventure recreation activities is conducive to developing preventive and coping strategies. This study conducted in-depth interviews with 21 land-based and water-based adventure recreationists. The interview transcripts were analyzed through a content analysis. The results indicated that the sources of concern over adventure recreation activities consisted of human, environment, and management aspects. The human sources of worry involved the lack of ability, being poorly equipped, and carelessness factors. The environmental sources of worry entailed environmental hazard and poor environmental adaptation factors. The management sources of worry originated from the improper maintenance of equipment and professional negligence factors. Subsequently, preventive and coping strategies from the recreationist and management perspectives were proposed as references for adventure recreationists. The strategies could help managers develop relevant countermeasures.
