Assessing The Functions Of Prescription Stimulant Abuse Among College Students, Matthew J. Dwyer Jul 2019

Assessing The Functions Of Prescription Stimulant Abuse Among College Students, Matthew J. Dwyer

Theses and Dissertations

Non-medical prescription stimulant use (NMPSU), such as using medications like Ritalin, Adderall, and Concerta without a prescription or at a higher dosage than prescribed, is a rising trend in American adults. Use is most prevalent among college age adults (18-25 years old). Survey research among experienced users has identified several reasons college students are engaging in NMPSU, including enhancement of cognitive, athletic, and social performance, but less is known about how the relative reinforcing value differs based on the reasons of use. Behavioral economic drug purchase tasks have been used to capture reinforcer strength and motivation related to use of …

The United States is in the midst of an opioid crisis, with more than 130 people dying each day from an opioid overdose (Centers for Disease Control and Prevention [CDC], 2018a).

Compared to other age groups, the prevalence of both heroin and prescription opioid use is particularly elevated among young adults (Sharma, Bruner, Barnett, & Fishman, 2016). While there is a large body of evidence demonstrating the effectiveness of substance use treatment in general, only …


A Longitudinal Investigation Of Interpersonal Trauma Exposure, Posttraumatic Stress Disorder, And Cannabis Use Phenotypes Among College Students, Terrell A. Hicks Jan 2019

A Longitudinal Investigation Of Interpersonal Trauma Exposure, Posttraumatic Stress Disorder, And Cannabis Use Phenotypes Among College Students, Terrell A. Hicks

Theses and Dissertations

College students have an increased risk for cannabis use, trauma exposure, and posttraumatic stress disorder (PTSD). Cannabis use disorder (CUD) and PTSD comorbidity is high, and given the negative consequences of the comorbidity (e.g., poor academic outcomes), there is a need to understand comorbid CUD-PTSD etiology. Two primary etiologic models exist: self-medication (i.e., PTSD à CUD) and high-risk (i.e., CUD à PTSD) hypotheses. This study 1) examined the prevalence and predictors of cannabis use and interpersonal trauma (IPT) exposure; 2) investigated the relationship between cannabis use and IPT; and 3) examined cannabis use, IPT, and PTSD through mediational self-medication and …
