The transtheoretical model (TTM) posits that processes of change and the pros and cons of smoking predict progressive movement through the stages of change. This study provides both a cross-sectional replication and a prospective test of this hypothesis. As part of a larger study of worksite cancer prevention (the Working Well Trial), employees of 26(More)
Relapse prevention remains a major challenge to smoking cessation efforts. T. H. Brandon, B. N. Collins, L. M. Juliano, and A. B. Lazev (2000) found that a series of 8 empirically based relapse-prevention booklets mailed to ex-smokers over 1 year significantly reduced relapse. This study dismantled 2 components of that intervention: the amount of content(More)
R. Eisenberger's (1992) learned industriousness theory states that individuals display differing degrees of persistence depending on their history of reinforcement for effortful behavior. These differences may influence the development, maintenance, and cessation of addictive behaviors. In cross-sectional studies, E. P. Quinn, T. H. Brandon, and A. L.(More)
Smoking-related cues tend to produce urges and cardiac responses in smokers. This reactivity has been assumed to reflect prior classical conditioning. However, little direct evidence exists supporting the notion that environmental cues can be classically conditioned to cigarette smoking. In this study, 8 smokers received 22 daily trials during which 2 cue(More)
The theory of "alcohol myopia" (C. M. Steele & R. A. Josephs, 1990) suggests that an intoxicated person is disproportionately influenced by immediate, superficial aspects of experience and that effortful, controlled cognitive processing is impaired. The present research examined the effects of alcohol intoxication on social inferences, which refer to(More)
OBJECTIVE To assess the validity of the stages of change (SOC) algorithm for current smokers. DESIGN This study was a mail-based, cross-sectional survey study of 242 adult smokers. MAIN OUTCOME MEASURES The main outcome measures were the SOC algorithm and a variety of alternative questionnaire items measuring motivation to quit smoking. RESULTS AND(More)
Longitudinal study designs in addictive behaviors research are common as researchers have focused increasingly on how various explanatory variables affect responses over time. In particular, such designs are used in intervention studies that have multiple follow-up points. These designs typically involve repeated measurement of participants' responses, and(More)
OBJECTIVE To assess the transtheoretical model applied to smoking cessation using the framework of N. D. Weinstein, A. J. Rothman, and S. R. Sutton (1998), which is the general framework for designing and evaluating stage models of health behavior. DESIGN Systematic review. RESULTS AND CONCLUSION The transtheoretical model applied to smoking cessation(More)
BACKGROUND Not much is currently understood regarding the contexts of cigarette and e-cigarette use among dual users. Proper application of e-cigarettes to smoking cessation or tobacco harm reduction would require an understanding of when and why dual users use cigarettes versus e-cigarettes. This study sought to elucidate the contexts of cigarette versus(More)
BACKGROUND Despite the fact that betel-quid is one of the most commonly used psychoactive substances worldwide and a major risk-factor for head-and-neck cancer incidence and mortality globally, currently no standardized instrument is available to assess the reasons why individuals chew betel-quid. A measure to assess reasons for chewing betel-quid could(More)
