Assessing the psychometric properties of smoking-related attitudes, self-efficacy, and intention among a diverse population of middle school students

The reliability and validity of the Temptations to Try Smoking Scale in a group of Chinese adolescents

OBJECTIVE

To provide a scientifc tool, the Temptations to Try Smoking Scale (TTSS) is introduced to evaluate its reliability and validity in preventing and intervening Chinese adolescents from smoking temptations.

METHODS

A questionnaire, including the TTSS, the Chinese version of the Decisional Balance Scale (CDBS), the Adolescent Smoking Curiosity Scale (ASCOS), and the Sensation-Seeking Scale (SSS), is used to test 1195 Chinese adolescent volunteers (214 of them are retested after 1 month). If all six items in the TTSS are retained, the exploratory factor analysis (EFA) reveals that the TTSS exhibits a structure of two factors: positive social and curiosity/stress.

RESULTS

The confrmatory factor analysis (CFA) shows that the two-factor model of the TTSS has the ftting indices χ2/df = 2.35, RMSEA = 0.06, and CFI = 0.99, which are better than those of its single-factor model. The total scores of the TTSS, positive social, and curiosity/stress are positively correlated with the scores of Pros, ASCOS, TAS, and Dis of SSS but negatively correlated with the Cons, hereby exhibiting good criterion-related validity. The internal consistency coefcient of the TTSS is 0.89, and the retest reliability is 0.90.

CONCLUSION

Therefore, the TTSS has good reliability and validity for Chinese adolescents and can be used as an efective tool to evaluate adolescents' smoking temptations in China.

Dynamic, data-driven typologies of long-term smoking, cessation, and their correlates: Findings from the International Tobacco Control (ITC) Netherlands Survey

RATIONALE

Efforts towards tobacco control are numerous, but relapse rates for smoking cessations remain high. Behavioral changes necessary for continuous cessation appear complex, variable and subject to social, biological, psychological and environmental determinants. Currently, most cessation studies concentrate on short-to midterm behavioral changes. Besides, they use fixed typologies, thereby failing to capture the temporal changes in smoking/cessation behaviors, and its determinants.

OBJECTIVE

To obtain long-term, data-driven longitudinal patterns or profiles of smoking, cessation, and related determinants in a cohort of adult smokers, and to investigate their dynamic links.

METHODS

The dataset originated from the International Tobacco Control (ITC) Netherlands Project, waves 2008 to 2016. Temporal dynamics of smoking/cessation, psychosocial constructs, and time-varying determinants of smoking were extracted with Group-Based Trajectory Modeling technique. Their associations were investigated via multiple regression models.

RESULTS

Substantial heterogeneity of smoking and cessation behaviors was unveiled. Most respondents were classified as persistent smokers, albeit with distinct levels of consumption. For a minority, cessation could be sustained between 1 and 8 years, while others showed relapsing or fluctuating smoking behavior. Links between smoking/cessation trajectories with those of psychosocial and sociodemographic variables were diverse. Notably, changes in two variables were aligned to behavioral changes towards cessation: decreasing number of smoking peers and attaining a higher self-perceived control.

CONCLUSION

The unveiled heterogeneity of smoking behavior over time and the varied cross-dependencies between smoking data-driven typologies and those of underlying risk factors underscore the need of individually tailored approaches for motivational quitting.
