某工專夜間部吸菸男生之戒菸意圖、戒菸行為及其影響因素之研究

A STUDY ON INTENTION AND BEHAVIOR TO QUIT SMOKING OF MALE STUDENTS IN A JUNIOR COLLEGE

本研究之主要目的在於運用Ajzen的計劃行為理論來預測並解釋某工專夜間部吸菸男生之戒菸意圖及戒菸行為。同時也比較理性行為理論與計劃行為理論二者在 解釋戒菸行為上的適用性。本研究在結構式問卷施測兩個月以後，以電話訪問的方式追蹤戒菸行為。結構式問卷施測共得175份有效問卷，行為追縱則完成了 147名。研究結果發現：在控制原菸量的影響力之後，本研究對象的戒菸行為（減菸量）可由戒菸意圖、知覺行為控制和戒菸經驗加以預測。而對戒菸的態度、主觀規範和知覺行為控制則可有效地解釋戒菸意圖。整體而言，本研究結果支持計劃行為理論的假設，並發現計劃行為理論應用在戒菸行為上，比理性行為理論更為合適。

The purpose of this study was to predict and explain the male students' intention and behavior to quit smoking by manipulating the Ajzen's Theory of Planned Behavior (TPB), as well as to compare the Theory of Reasoned Action (TRA) with TPB to understand which one was more feasible on explaining the adaptation of behavior to quit smoking. This study has followed up 147 subjects' behavior to quit smoking by telephone interview two months after questionnaire survey was conducted. The main findings were: (l) the intention to quit smoking, perceived behavioral control and experience on quitting smoking could predict subjects' behavior to quit smoking after controlling the influence of average number of cigarettes smoked per day; (2) the attitude toward quitting smoking, subjective norm and perceived behavioral control could explain the subjects' intention to quit smoking; (3) the results of this study supported the hypothesis of the TPB an drevealed that the TPB was more feasible than TRA on predicting behavior to quit smoking.
