目的：本研究在分析國立臺灣大學學生之休閒運動心理需求、生活壓力與幸福感之現況，以及探究各變項間的關聯情形。方法：本研究以國立臺灣大學之大學部學生為對象，採用問卷方式 (含個人背景變項、休閒運動心理需求、生活壓力及幸福感等量表) ，以立意取樣進行調查，共取得有效樣本481 份。結果：學生之休閒運動心理需求以「自主性」最高；生活壓力以「課業壓力」最高；學生的整體幸福感有提升之空間。休閒運動心理需求、生活壓力與幸福感之相關分析方面，在休閒運動心理需求與主觀幸福感有顯著的正相關；在生活壓力與主觀幸福感的關係方面，其結果則有顯著的負相關。休閒運動心理需求、生活壓力對幸福感之預測情形，在休閒運動心理需求變項中的勝任感構面、生活壓力變項中的課業壓力、家庭壓力、人際關係、生涯發展等構面對幸福感有顯著的解釋力。結論：當學生在休閒運動心理需求中的勝任感滿意程度越高時，其知覺幸福感就會越高；當學生知覺在生活壓力中的課業壓力、生涯發展、家庭壓力、人際關係等壓力程度越大時，則知覺幸福感就會越低。因此，瞭解大學生對休閒運動心理需求及生活壓力的情形，並規畫完善的相關措施，以紓解繁重的生活壓力，進而提升學生的幸福感受，即顯得相當重要且務實的作法，而須加以持續的關注與探究。

Taking the college students at National Taiwan University as the subjects of study, this research adopts questionnaire (including personal background variables, psychological needs, life stress and well-being for recreational sports) and purposive sampling to obtain a total of 481 valid samples. ＂Autonomy＂ ranks the highest among psychological needs. ＂Academic pressure＂ ranks the highest among daily life stress.
