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)
This paper is part of a series that has the goal of identifying potential approaches toward developing new instruments for assessing tobacco dependence among adolescents. The fundamental assumption underlying the series is that contemporary theories of drug dependence offer a rich source of opportunities for the development of theoretically based assessment(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)
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)
BACKGROUND Betel quid is the fourth most commonly consumed psychoactive substance in the world. The Betel Quid Dependence Scale (BQDS) is the first instrument designed specifically to measure betel quid dependence. The three factor structure of the BQDS consists of "physical and psychological urgent need," "increasing dose," and "maladaptive use." The BQDS(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)
BACKGROUND E-cigarette use outcome expectancies and their relationships with demographic and e-cigarette use variables are not well understood. Based on past cigarette as well as e-cigarette use research, we generated self-report items to assess e-cigarette outcome expectancies among college students. The objective was to determine different dimensions of(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)
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)
