OBJECTIVE Motivational interviewing (MI) is a treatment approach that has been widely examined as an intervention for tobacco dependence and is recommended in clinical practice guidelines. Previous reviews evaluating the efficacy of MI for smoking cessation noted effects that were modest in magnitude but included few studies. The current study is a(More)
RATIONALE There has been little study of the very early time course of the smoking withdrawal syndrome, despite its relevance to the maintenance of both smoking and postcessation abstinence. The literature contains a range of estimates about the early appearance of withdrawal symptoms, but without reference to empirical data. OBJECTIVES The study aim was(More)
AIMS To develop and validate a measure of smokers' expectancies for the abstinence process upon quitting smoking: the Smoking Abstinence Questionnaire (SAQ). DESIGN Principal component analysis and other psychometric analyses of self-report data. SETTING San Francisco, California. PARTICIPANTS A total of 507 adult smokers of at least 10 cigarettes per(More)
Electronic cigarettes (ECIGs) use an electric heater to aerosolize a liquid that usually contains propylene glycol, vegetable glycerin, flavorants, and the dependence-producing drug nicotine. ECIG-induced nicotine dependence has become an important concern, as some ECIGs deliver very little nicotine while some may exceed the nicotine delivery profile of a(More)
AIM To evaluate potential mediators of an extended cognitive behavioral smoking cessation intervention. DESIGN Analysis of data from a randomized clinical trial of smoking cessation. SETTING The Habit Abatement Clinic, University of California, San Francisco. PARTICIPANTS Participants were older cigarette smokers (>/=50 years old). Those receiving(More)
Smoking cessation is crucial for reducing cancer risk and premature mortality. The US Preventive Services Task Force (USPSTF) has recommended annual lung cancer screening with low-dose computed tomography (LDCT), and the Center for Medicare and Medicaid Services recently approved lung screening as a benefit for patients ages 55 to 77 years who have a 30(More)
Although it has been suggested that implicit expectancies influence smoking and other addictive behaviors, there is little direct evidence to support this notion. This study offers the first step in exploring implicit expectancy operation in cigarette smoking. Ninety-nine college smokers completed the sentence, "Smoking makes one_____." with as many words(More)
Irvin and Brandon (Nicotine & Tobacco Research, 2, 79-84, 2000) reported a significant decline in reported abstinence rates between 1977 and 1996 from clinical trials of cognitive-behavioral smoking cessation treatments based on coping skills training. The present study extends that approach to the analysis of pharmacotherapy trials. A literature search(More)
The female hormone progesterone (P4) promotes the expansion of stem-like cancer cells in estrogen receptor (ER)- and progesterone receptor (PR)-positive breast tumors. The expanded tumor cells lose expression of ER and PR, express the tumor-initiating marker CD44, the progenitor marker cytokeratin 5 (CK5) and are more resistant to standard endocrine and(More)
Mental health problems are endemic across the globe, and suicide, a strong corollary of poor mental health, is a leading cause of death. Classic psychedelic use may occasion lasting improvements in mental health, but the effects of classic psychedelic use on suicidality are unknown. We evaluated the relationships of classic psychedelic use with(More)
