开发戒烟自我效能问卷调查
2012/04/06
背景：自我效能信念是健康行为（变化）的重要决定因素。在戒烟领域，有必要开发简短、可行和有效的问卷调查，检测有关戒烟的自我效能信念。
目的：本研究对含6个项目的评价戒烟自我效能的问卷调查的心理测量学特性进行研究。
方法：数据来自于意向戒烟研究的纵向数据。513名吸烟者完成戒烟自我效能问卷调查（SASEQ），该问卷调查对抑郁症状和戒烟动机进行评价。此后，受试者设定一个戒烟日期，并尝试开始戒烟。戒烟日期1年后，通过受试者主诉来判断参与者的吸烟状态。对SASEQ的心理计量学特征进行分析，并研究SASEQ评分是否能预测成功戒烟。
结果：因素分析找到一个因素，其特征值为3.83，能解释64%的变异。所有因素负荷量≥0.73。结果显示，SASEQ的克龙巴赫阿尔法为0.89，SASEQ与抑郁症状和戒烟动机相关性较低，这表明自我效能的检测独立于这些参数。此外，基础水平SASEQ评分较高能显著预测戒烟日期52周后的戒断(OR = 1.85；95% CI = 1.20～2.84)。
结论：SASEQ是一个简短的、可靠的和有效的评价戒烟自我效能信念的问卷调查。本研究显示，该调查具有较好的预测效能。简短SASEQ问卷调查能用于繁忙的临床实践，指导戒烟干预措施的实施。

Abstract
BACKGROUND: Self-efficacy beliefs are an important determinant of (changes in) health behaviors. In the area of smoking cessation, there is a need for a short, feasible, and validated questionnaire measuring self-efficacy beliefs regarding smoking cessation.
PURPOSE: The purpose of this study is to investigate the psychometric properties of a six-item questionnaire to assess smoking cessation self-efficacy.
METHODS: We used longitudinal data from a smoking cessation study. A total of 513 smokers completed the Smoking Abstinence Self-efficacy Questionnaire (SASEQ) and questionnaires assessing depressive symptoms and motivation to quit smoking. After that, they set a quit date and attempted to stop smoking. One year after the quit date, smoking status of participants was assessed by self report. The psychometric properties of the SASEQ were studied and we investigated whether SASEQ scores predicted successful smoking cessation.
RESULTS: Factor analysis yielded one factor, with an Eigenvalue of 3.83, explaining 64% of variance. All factor loadings were ≥0.73. We found a Cronbach’s alpha of 0.89 for the SASEQ, low correlations for the SASEQ with depressive symptoms, and motivation to quit, indicating that self-efficacy is measured independently of these concepts. Furthermore, high baseline SASEQ scores significantly predicted smoking abstinence at 52 weeks after the quit date (OR = 1.85; 95% CI = 1.20～2.84).
CONCLUSIONS: The SASEQ appeared to be a short, reliable, and valid questionnaire to assess self-efficacy beliefs regarding smoking abstinence. In the present study, this instrument also had good predictive validity. The short SASEQ can easily be used in busy clinical practice to guide smoking cessation interventions.
