臺灣擁有豐富多變的自然景觀,3,000公尺以上的高山有258座,中、低海拔的山林地帶更是山峰林立。而現代人閒暇時間增加,交通發展日愈便利、資訊日漸多元開放且健康意識的抬頭,自然的山林成為許多國人休憩活動的場所,在周末或休假日藉著登山健行活動紓解平時的生活壓力。 在登山健行活動發展日益蓬勃下,本研究欲探討登山健行活動參與者之人格特質、休閒動機、休閒阻礙及休閒效益的關係。本研究以一年內曾從事登山健行活動之參與者為研究對象,採用問卷調查法,以便利抽樣與滾雪球抽樣之方式回收有效問卷570份,使用SPSS及結構方程模式進行資料分析及研究假設驗證。研究結果顯示:(1) 登山健行者人格特質中外向性、友善性與開放性對休閒動機呈現正向顯著性影響。(2) 登山健行者人格特質中嚴謹性對身心健康動機呈現正向顯著性影響。(3) 登山健行者人格特質中外向性對個人阻礙與人際阻礙呈現負向顯著性影響。(4) 登山健行者人格特質中神經質對休閒阻礙呈現正向顯著性影響。(5) 登山健行者人格特質中友善性對休閒阻礙呈現負向顯著性影響。(6) 登山健行者人格特質中開放性對個人阻礙呈現負向顯著性影響。(7) 登山健行者之休閒動機對休閒效益呈現正向顯著性影響。(8) 登山健行者之結構阻礙對身心健康效益呈現負向顯著性影響。 以上研究結果可提供做為觀光局與體育署等相關單位在推動登山健行活動及規劃登山步道時的參考。 There are rich and various landscapes in Taiwan, including 258 high mountains over 3000 meters, and serried peaks from low to middle elevation regions. With the convenience of transportation and the fast-developed information technology, more and more people choose to do outdoor activities to spend their free time and make themselves become stronger and healthier. In this way, the natural mountains and trails are the place which people go to. By hiking on weekends or holidays, people can release their pressure in life.

The subjects of this study are the people who joined hiking activities within one year. The researchers sent questionnaires online and got 570 valid questionnaires. SPSS and Structure equation modeling (SEM) are used to analyze the data and test the hypotheses. The findings are stated as following: (1) Hikers' extraversion, agreeableness and openness positively correlated with their leisure motivation.(2) Hikers' conscientiousness positively correlated with their physical and mental health motivation.(3) Hikers' extraversion negatively correlated with their intrapersonal and interpersonal constrains.(4) Hikers' neuroticism positively correlated with their leisure constrains.(5) Hikers' agreeableness negatively correlated with their leisure constrains.(6) Hikers' openness negatively correlated with their intrapersonal constrains.(7) Hikers' leisure motivation positively correlated with their leisure benefits.(8) Hikers' structural constrains negatively correlated with their physical and mental health motivation.
