This study assessed the factor structure, internal consistency, and concurrent validity of the Smoking Expectancies Scale for Adolescents (SESA) using 717 Australian adolescents (87% nonsmokers, 11% current smokers, and 2% ex-smokers). Exploratory factor analysis of SESA yielded 8 factors. Confirmatory factor analysis indicated that the 8-factor model, and also a 2nd-order cost-benefit model, fit the data significantly better than 4 alternatives. Validation analyses revealed the 8-factor model explained 26% to 32% of the variance in adolescent cigarette use, smoking intentions, smoking subjective norms, and peer smoking. The 2nd-order model explained 12% to 17% of the variance in these same variables.
本研究使用717名澳大利亚青少年（87%为非吸烟者，11%为当前吸烟者，2%为既往吸烟者）评估了青少年吸烟预期量表（SESA）的因子结构、内部一致性和同时效度。对SESA进行探索性因子分析得出8个因子。验证性因子分析表明，8因子模型以及二阶成本效益模型对数据的拟合显著优于4种替代模型。效度分析显示，8因子模型解释了青少年吸烟行为、吸烟意愿、吸烟主观规范和同伴吸烟情况中26%至32%的方差变异。二阶模型解释了这些相同变量中12%至17%的方差变异。
