Cigarette smoking is a health-risk behavior of global proportions. Self-efficacy plays an important role in both smoking acquisition and smoking resistance. Reliability and validity of an instrument is fundamental to research results, particularly in its simplified form on a different population. The purpose of this study was to conduct psychometric testing on the parsimonious Chinese version of the Smoking Self-efficacy Survey (CSSES-20).
The randomized cluster sample was drawn from 61 middle schools in Taipei City, Taiwan. Following a pilot test of the CSSES-20, the CSSES was administered to 571 adolescents. Construct validity was tested by the exploratory factor procedures and the contrasted group approach. Pearson correlation coefficients were used to examine the criterion validity and test-retest reliability for the stability of the scale. Cronbach's alpha coefficients were used to determine the internal consistency of the scale.
The exploratory factor analysis yields three components, "opportunity to smoke,""emotional stress," and "influence of friends," accounting for 80.4% of the total variances. The criterion validity was also supported by the study results. The contrasted group approaches affirmed the construct validity of the CSSES-20. Stability of scales was supported by test-retest reliability. Cronbach's alphas for 3 subscales ranged from .90 to .93.
A concise instrument can alleviate response burden for adolescent study participants and increase their recruitment and retention rates. The CSSES-20 demonstrated satisfactory construct validity, criterion validity, stability, and internal consistency reliability. These findings can be used to provide school teachers and nurses with information about the relationship between self-efficacy to resist smoking and adolescent smoking behavior.
吸烟是一种全球性的健康风险行为。自我效能感在吸烟的获得和抵制中都起着重要作用。工具的可靠性和有效性是研究结果的基础，尤其是在针对不同人群的简化形式上。本研究旨在对简化版的中文版吸烟自我效能感量表（CSSES-20）进行心理测量学测试。
该随机整群样本来自中国台湾台北市的 61 所中学。在对 CSSES-20 进行试点测试后，对 571 名青少年进行了 CSSES 测试。通过探索性因素程序和对比组方法来检验结构有效性。使用皮尔逊相关系数来检验效标效度和量表的稳定性的重测信度。使用 Cronbach's alpha 系数来确定量表的内部一致性。
探索性因素分析得出三个成分，“吸烟机会”、“情绪压力”和“朋友影响”，占总方差的 80.4%。研究结果也支持效标效度。对比组方法肯定了 CSSES-20 的结构有效性。量表的稳定性得到重测信度的支持。3 个子量表的 Cronbach's alpha 值范围在.90 到.93 之间。
一个简洁的工具可以减轻青少年研究参与者的反应负担，提高他们的招募和保留率。CSSES-20 表现出令人满意的结构有效性、效标效度、稳定性和内部一致性信度。这些发现可用于向学校教师和护士提供有关抵制吸烟的自我效能感与青少年吸烟行为之间关系的信息。
