To address observations that the smoking identities of youth are valid descriptors of their smoking behaviour, we examined the relationships between self-reported smoking identities, perceived levels of addiction, and established taxonomies of smoking behaviour of youth.
Cross-sectional data were collected on demographics, perceived extent of addiction to tobacco, smoking history, and self-reported smoking identity from questionnaires administered to 8225 students in British Columbia, Canada. A total of 7246 participants were categorised according to four smoking taxonomies established in the literature. Differences in perceived physical and mental addiction between smoking identity groups were calculated. The strength of the associations between the taxonomies of smoking and the smoking identity groups was also assessed.
There were significant differences in perceived levels of physical (Kruskal-Wallis chi(2) = 3985.02, p<0.001) and mental (Kruskal-Wallis chi(2) = 4046.09, p<0.001) addiction to tobacco by the participants' self-reported smoking identity. Youth smoking identities were modestly associated with the established smoking taxonomies (Pearson C contingency coefficient = 0.64-0.72).
Self-reported smoking identities appear to provide valid characterisation of the smoking behaviour of youths that complement and elaborate existing taxonomies of smoking behaviour. Questions about self-reported smoking identity should be used in conjunction with smoking behaviour taxonomies when investigating youth smoking behaviours.
为回应有关青少年吸烟身份是其吸烟行为有效描述指标的观点，我们研究了青少年自我报告的吸烟身份、感知成瘾程度与既定吸烟行为分类之间的关系。
通过对加拿大不列颠哥伦比亚省8225名学生进行问卷调查，收集了有关人口统计学、感知烟草成瘾程度、吸烟史以及自我报告吸烟身份的横断面数据。根据文献中建立的四种吸烟分类法，对总共7246名参与者进行了分类。计算了吸烟身份组之间在感知身体和心理成瘾方面的差异。还评估了吸烟分类法与吸烟身份组之间关联的强度。
参与者自我报告的吸烟身份在烟草的感知身体成瘾程度（Kruskal-Wallis卡方检验=3985.02，p<0.001）和心理成瘾程度（Kruskal-Wallis卡方检验=4046.09，p<0.001）方面存在显著差异。青少年吸烟身份与既定的吸烟分类法有适度关联（Pearson C列联系数=0.64 - 0.72）。
自我报告的吸烟身份似乎能有效描述青少年的吸烟行为，对现有的吸烟行为分类法起到补充和细化作用。在调查青少年吸烟行为时，关于自我报告吸烟身份的问题应与吸烟行为分类法结合使用。
