The aim of this study was to examine the relationship between cessation and age at which person starts smoking. Data from a survey of nine neighborhoods in Philadelphia (1985-1987) were analyzed. Interviews were conducted in the home using a structured questionnaire. Participants were from a probability sample (n = 1,700) of males aged 35 years or older. Sixty-six percent of the smokers in this series started smoking before 18 years of age. Smoking cessation rate was 58.1% in Whites and 38.8% in Blacks. Age, race, marital status, education, health condition, amount smoked, and duration of smoking were significant predictors of smoking cessation. Age at initiation of smoking was a significant factor for continuation of smoking. Men who started smoking before 16 years of age had an odds ratio of 2.1 (95% confidence interval: 1.4-3.0) for not quitting smoking compared to those who started at a later age. These findings emphasize the need for prevention program targeted to children below 16 years of age. (C) 1999 Elsevier Science Ltd.

A 10-item questionnaire (the Tobacco Dependence Screener;TDS) for screening of tobacco/nicotine dependence according to ICD-IO, DSM-III-R, and DSM-IV was newly developed. The reliability and validity were assessed in three samples of smokers in Japan. A total of 58 male smokers completed the TDS and the Fagerstrom Tolerance Questionnaire (FTQ), and they were interviewed using the World Health Organization's Composite International Diagnostic Interview (Sample 1). A total of 118 male and 36 female smoking outpatients completed the TDS and the FTQ and provided a breath sample for carbon monoxide measurement (Sample 2). A total of 194 male smokers joined a health education program using a health risk appraisal (HRA) and reported their smoking status and completed the TDS 6 months after receiving the HRA results (Sample 3). The Cronbach's alpha coefficients for the TDS ranged from .74 to .81 among the samples, whereas those for the FTQ ranged from .41 to .64. Receiver operator characteristic analyses indicated that the TDS had a better screening performance for ICD-10, DSM-III-R, and DSM-IV diagnoses than did the FTQ. The TDS score significantly and positively correlated with the severity of the diagnoses, the carbon monoxide levels, number of cigarettes smoked per day, and years of smoking. The TDS score was significantly lower in those who quit smoking than in those who did not quit smoking after the HRA. It is suggested that the TDS is a reliable and useful screening questionnaire for tobacco/nicotine dependence according to ICD-10, DSM-III-R, and DSM-IV. (C) 1999 Elsevier Science Ltd.

This paper describes the curricula contents, and presents data to evaluate the implementation, process and immediate post-test knowledge of Project Towards No Tobacco Use (Project TNT). Four different school-based tobacco use prevention curricula were developed to counteract the effects of three types of tobacco use acquisition variables typically addressed within a comprehensive social influences program: (1) peer approval for using tobacco (normative social influence), (2) incorrect social informational provided about tobacco use (information social influence) and (3) lack of knowledge or misperceptions about physical consequences resulting from tobacco use. Three curricula were designed to counteract the effects of single acquisition variables, whereas a fourth curriculum was designed to counteract the effects of combined social and physical consequences-related influences. These curricula were delivered to seventh grade students by trained project health educators to maximize implementation. 'Program' schools, those schools that received one of these curricula, were compared to 'control' schools that provided asystematic health education delivered by school personnel. A total of rive conditions were contrasted through use of a randomized experiment involving 48 southern California junior high schools. This paper documents high levels of implementation in all program conditions. Also, favorable process ratings were obtained across the four program conditions, using multiple measures and sources of ratings (students, health educators and classroom teachers who observed curricula delivery). Finally, knowledge item sets completed by the students demonstrated discriminant validity across all five conditions. Because the program conditions were discriminable, yet were quite similar in implementation and process ratings, planned future study of behavioral outcomes can be interpreted as relatively uncontaminated by delivery or credibility confounds.
