目標：利用焦點團體討論法收集資料，探討國中生的幽默概念及相關經驗。方法：自台灣北、中、南、東四個地區各選取一所國中。徵得校方同意後，從各校一至三年級學生中，隨機抽出8名男生和8名女生，再依性別分成男生組和女生組。最後有八個團體共64位國中生參與焦點團體討論。2005年底，根據各校排定的日程前去執行焦點團體，討論過程以錄音筆全程錄音並輔以觀察員之文字記錄。所有錄音內容及觀察記錄均鍵入電腦轉成逐字稿後，由研究人員共同閱讀及討論，完成質性資料的歸納與分析。結果：1.學生普遍認為幽默與「好笑」、「脫離慣性思考」或「負面形容詞」有關；2.根據學生的經驗，表現幽默的方式可歸納成貶抑自己、貶抑他人、言語動作和機智反應四種類型；3.幽默表現的主題多與「個人特色」或「生活事件」有關，尤以「性議題」及「黃色笑話」最常被提及；4.多數學生認為「正向的幽默表現」對心理及社會健康有幫助。結論：國中生對於幽默之概念及表現有正反兩方之看法，唯多數人認為「正向的幽默表現」有助於壓力抒解且對心理和社會健康有益。至於幽默表現是否確實與健康有關，值得繼續做更廣泛且深入的探討。

Objectives: To investigate the concept and experiences of humor among junior high school students in Taiwan through focus group discussions. Methods: Four junior high schools were selected from the northern, southern, eastern, and western regions of Taiwan, respectively. Eight boys and eight girls were randomly selected from grades 7 to 9 in each school, and their consent to participate in the study was obtained. The students were grouped for discussion by sex, resulting in a total of 64 students in eight focus groups. The focus group discussions were carried out in late 2005 at times arranged by each school. The discussions were taped using a mini-digital recorder in addition to being documented by the observer's written notes. The contents of the recordings and the observer's notes were entered into a computer word for word. The resulting manuscripts were then read and discussed by the researchers and the final data summarized and analyzed. Results: 1. Students commonly associate humor with "funny," "escaping inertia of thought," or "negative adjectives." 2. Based on students' experiences, humor consists of four types: making fun of oneself, making fun of others, verbal or physical humor, and quick-witted reactions. 3. The topics about which students express humor are related to individual characteristics and life events, with sex topics and dirty jokes predominating. 4. Students believe that the positive expression of humor is beneficial to psychological and social health. Conclusions: Junior high school students have both positive and negative attitudes toward the concept of humor and performance patterns. They believe that the positive expression of humor can help relieve stress and is beneficial to psychological and social health. The exact relationship between humor performance and health deserves in-depth future research.
