Outcome Expectancies Mediate The Impact Of Olfactory Cues On Marijuana Craving, Mallory Loflin
Outcome Expectancies Mediate The Impact Of Olfactory Cues On Marijuana Craving, Mallory Loflin
Legacy Theses & Dissertations (2009 - 2024)
Current work suggests that the presence of "craving" may be a significant indicator of problematic substance use. Nevertheless, little work has examined how cannabis users experience and develop craving. Most relevant studies focus on samples in treatment. Previous work suggests that cues for marijuana might activate outcome expectancies that contribute to the development of craving. The present study sought to test whether an olfactory marijuana cue would create changes in expectancy, mood, and craving in a non-treatment seeking sample representing both users and non-users. Unlike control cues, olfactory cues for marijuana increased perceptions of the likelihood of marijuana-induced positive outcomes …
The Acquired Preparedness Model And Impulsivity Moderated Expectancies : Examining Predictors Of Marijuana Use, Jamie Rae Bolles
The Acquired Preparedness Model And Impulsivity Moderated Expectancies : Examining Predictors Of Marijuana Use, Jamie Rae Bolles
Legacy Theses & Dissertations (2009 - 2024)
The Acquired Preparedness Model suggests that links between personality and substance use are mediated by expectancies. Expectancy-moderated links between personality and substance use also have support in previous research. The current study sought to extend the Acquired Preparedness Model to a diverse sample of frequent marijuana users. Tension-reduction expectancies, impulsivity, and ounces of marijuana used per month were assessed in 5,996 participants recruited from a marijuana policy listserv. Tension-reduction expectancies partially mediated the relation between impulsivity and marijuana use. Additionally, expectancies and impulsivity interacted to predict marijuana use, with impulsivity showing a stronger link to use when expectancies increased. These …
