Abstract
本研究運用計畫行為理論為研究架構，目的為預測及解釋國中學生從事吸菸行為的意圖。研究對象為臺北市某國中的364位男、女學生，蒐集其有關吸菸行為的信念、態度、主觀規範、知覺行為控制和行為意圖的資料，研究結果則以多元邏輯斯迴歸分析進行分析。
本研究重要分析結果如下：
一、本研究在吸菸行為意圖的關聯強度方面，模式內變項的態度與主觀規範對吸菸行為意圖的關聯強度為26.2％，加入知覺行為控制為第三個模式內變項後，關聯強度提升3.2％，關聯強度為29.4％。
二、態度與行為信念、結果評價之交乘積和達顯著輕微相關，主觀規範與規範信念、依從動機之交乘積和未達顯著相關，知覺行為控制與控制信念、知覺力量之交乘積和達顯著輕度相關。
三、外在變項（父母婚姻狀況、過去吸菸經驗等）無法直接影響吸菸行為意圖。
四、行為信念、規範信念和控制信念與吸菸行為意圖呈顯著相關。
本研究結果可以提供衛生教育者發展相關介入，可進一步探究如何降低國中學生產生吸菸行為之意圖。
The purpose of this study was to predict and explain the junior high school students’intention regarding using tobacco. The Theory of Planned Behavior (TPB) provided the framework for the study. Beliefs, attitudes, subjective norms, perceived behavioral control and intention regarding tobacco using were obtained from 364 male and female junior high school students. The results were evaluated by multiple logistic regressions. There were major findings as the following: 1.The strength of association of the attitude and subjective norm to the intention regarding using tobacco was 26.2%; the perceived behavior control added 3.2% strength of association. Thus, the strength of association of these three variables accounted for 29.4%. 2.The attitude of respondents toward tobacco using behavior was moderately positive related to the product of behavioral beliefs multiplied by evaluations of outcomes (Bi*Ei). The subjective norm of respondents’ tobacco using behavior was not significant related to the product of normative beliefs multiplied by motivations to comply (NBj*MCj). The perceived behavior control of respondents’’ tobacco using behavior was significant moderately positive related to the control beliefs multiplied by perceived power (Ci*Pi). 3.No external variables (Parent marital status, experience of using tobacco, etc.) can directly affect intention regarding tobacco using. 4.Behavioral beliefs, normative beliefs and control beliefs were significantly related to intention regarding tobacco using. Implications for use of this findings by health educators in developing relevant intervention to prevent tobacco using behavior are discussed.
