彰化縣某國中學生執行充足睡眠行為意圖研究---計畫行為理論之應用

Abstract

本研究主要應用Ajzen的計劃行為理論(Theory of Planned Behavior)來探討某國中學生執行充足睡眠行為意圖。以彰化縣某國中七至九年級學生為母群體，採分層集束抽樣法抽出9班328人為對象，有效問卷共322份。研究工具採結構式問卷，所得資料用描述性統計、T檢定、單因子變異數分析、皮爾森積差相關、階層迴歸分析和賀德臨 T²分析法等統計方法進行資料處理、分析後，主要研究結果如下： 1.約五成研究對象在未來兩個月內有執行充足睡眠行為之意圖。 2.研究對象對執行充足睡眠行為的態度、主觀規範及知覺行為控制，可以解釋行為意圖40.3%的變異量，其中又以知覺行為控制最重要。 3.研究對象對執行充足睡眠行為的態度與行為信念、結果評價的交乘積和呈正相關；主觀規範與規範信念、依從動機的交乘積和呈正相關；知覺行為控制與控制信念、控制強度的交乘積和呈正相關。 4.有無意圖者在行為信念、結果評價、規範信念、依從動機、控制信念和控制強度等六類概念上有整體性的差異存在

The main purpose of this study was to investigate junior high school students’ intention of having enough sleep and related factors based on Theory of Planned Behavior (TPB). By using stratified cluster sampling method, the respondents were selected from 7-9 grade students of a junior high school in Changhua County in 2007school year. A structured questionnaire was used to collect the data. Totally, 322 valid questionnaire (98.2% response rate) were analyzed using t-test, one-way ANOVA, Pearson product-moment correlation, Regression and Hotelling T². The main findings of the study were as follows: 1. Around half of the respondents showed the positive behavioral intention for having enough sleep in the next two months. 2. The attitudes, subjective norms and perceived behavioral control could effectively explain 40.3% of variance of intention of having enough sleep. Perceived behavioral control was the most important factor of behavioral intention. 3. The attitude towards having enough sleep was significant positively related to the sum of product of behavioral beliefs multiplied by evaluations of outcomes. Also, the subjective norm towards having enough sleep was significant positively related to the sum of product of normative beliefs multiplied by motivations to comply. The perceived behavior control towards having enough sleep was significant positively related to the sum of product of controll beliefs multiplied by power. 4. There were significant differences in behavioral beliefs, evaluations of outcomes, normative beliefs, motivations to comply, control beliefs and power between subjects with and without the intention of having enough sleep.
