本研究旨在探討某夜二專學生在性行為時使用保險套之相關因素及有關愛滋防治教育之需求，研究採問卷調查法，問卷包括愛滋之知識、使用保險套之行為意向與預防愛滋之行動等，並以二年級全體870人(有效問卷671份)為調查對象，但只選取其中有過性行為之165人(女生110人;男生55人)為研究樣本，資料經SAS分析討論後，結論如下:某夜二專學生在性行為時使用保險套之相關因素及有關愛滋防治教育之*1.有24.2%的學生在與主要性伴侶性交時會每次使用保險套，有20.9%的學生在與次要性伴侶性交時會使用，學生與主要性伴侶使用保險套的比率明顯的高於次要性伴侶。2有上愛滋課程者明顯的比沒上者在性交時會每次使用保險套;此外使用保險套社會規範、保險套之行為意向與安全性溝通等可促使保險套之使用;而性之接受度與保險套之障礙愈高者在性行為時愈不會使用保險套。3.影響學生愛滋知識的是愛滋課程而非性別。4.學生感興趣的主題為愛滋預防法及愛滋傳染途徑;有上過愛滋課的女生比沒上課的男生傾向選擇較多的上課時數。5.受試者認為問題對健康較無威脅(如約會與擇偶)傾向於尋求非正式的協助如朋友;受試者認為問題對健康較具威脅(如可能感染HIV)則傾向於尋求正式協助系統如醫師。最後本研究建議男生也要上愛滋病教育，因大部份的性行為是男女共同參與的，只教女生而不教男生不但事半功倍，且不合乎時代潮流。

The purpose of this study was to investigate the influential factors of the use of condom when sexual intercourse occurs among two-year college night school students. In addition, the study is aimed to probe about the students, needs for AIDS preventive education. Questionnaires on the knowledge, intention, and enactment of HIV preventive behaviors were administered to a total of 870 students; 671 samples are recognized as effected, 165 students (55males and 110 females) out of the effective samples have had sexual intercourse; then the data are processed through SAS statistical analysis and the findings are listed as below:1.24.2% of the students with primary sexual partners use condom when each intercourse occurs, and 20.9% use condom in secondary sexual partners. Students with primary sexual partners use condom more often than those with secondary sexual partners.2.The students who take the AIDS course may significantly use condom when each intercourse occurs. In addition, higher frequency of condom use is correlated with clearer condom norms, better health protective sexual communication, and stronger intention to use condom; By contrast,lower frequency of condom use is correlated with higher acceptance of sexuality and greater perceived barriers when each intercourse occurs.3.The most significant factor that influences students, knowledge about AIDS is the AIDS course, not the gender.4.The topics that students are most interested in the AIDS course is the trasmission and protective methods of HIV infection. Moreover, females students who have taken the class of AIDS are more likely to choose more AIDS course hours than males who have not taken the lessons before.5.When the sexual problem is not threat to health (e.g., dating or mate-selection), students may gets help from informal system, such as friends. When the problem can harm health (e.g., one may catch HIV), they tend to search help from formal system, such as physicians. It is not only against the tide but also provides limited effects to educate only females students about AIDS since most sexual intercourse occur between men and women. Therefore, the study suggested that males students should receive AIDS preventive education as well.I
