Social Transmission Of Ethanol Preference In A Sign-Tracking Paradigm, Pat Severino

Seton Hall University Dissertations and Theses (ETDs)

The Observer/ Demonstrator Effect suggests that rats can socially obtain preferences for novel foods/drugs by interacting with experienced conspecifics. Sign-tracking is a paradigm which uses a conditioning procedure to evoke compulsive-like behaviors directed towards a tangible conditioned stimulus (CS) paired with a motivating unconditioned stimulus (US). The present study investigated the possibility that increased alcohol use results from the combination of socially transmitted cues and the kind of conditioning effect seen in sign-tracking procedures. Therefore, it was hypothesized that social exposure to an alcohol-experienced conspecific would summate with the conditioning experience and increase the sign-tracking of a bottle CS containing …

Cannabinoid-Induced Behavioral Sensitization In Adolescent Sprague-Dawley Rats, Michelle Stone

Electronic Theses, Projects, and Dissertations

Adolescent cannabis use has grown because of increased availability and higher societal acceptance. This increase in cannabis use is problematic as adolescents who experiment with cannabis are more likely to abuse cannabis and experiment with other illicit drugs such as cocaine. The reason for the greater susceptibility to drugs use is unclear and may be the result of altered drug sensitivity after cannabis exposure. Thus, the present investigation used the behavioral sensitization paradigm to examine the behavioral response of early adolescent rats to the cannabinoid agonist CP 55,940 (CP) or cocaine after repeated cannabinoid administration. It was hypothesized that: (1) …

Contextual Perspectives On Heroin Addiction And Recovery: Classic And Contemporary Theories, Sarah L. Callahan

College of Science and Health Theses and Dissertations

Drug use and recovery have received considerable attention from social scientists over the past few decades. However, many studies involving heroin use continue to focus on person-centered risk factors surrounding use and, to a lesser extent, recovery processes. There is a need to further develop and use theories that focus on contextual approaches that include opportunity structures and behavioral economic factors. In this article, two classic criminological theories (Differential Opportunity and Subcultural) are reviewed as well as the more recent Social Resource theory (SRT). Differential Opportunity theory focuses on the fact that those involved in illegitimate means of opportunity require …

Anticipatory Motivation For Drinking Alcohol: An In-Vivo Study, Bryan Benitez

USF Tampa Graduate Theses and Dissertations

Numerous studies from various research groups have already shown the usefulness of alcohol expectancies as predictors of long-term future alcohol consumption. The present study extends this line of research by directly testing whether alcohol expectancies measured in the moment using free association are useful as predictors of alcohol consumption in the next few hours. An ecological momentary assessment (EMA) procedure was used to examine how alcohol expectancies might fluctuate during days in which many people expect to drink (e.g. Fridays, Saturdays) and how these fluctuations in alcohol expectancies might predict future drinking and/or co-vary with important contextual variables during that …

This article documents the development of a community-based drug intervention for low- to mild-risk drug users who surrendered as part of the Philippine government's anti-drug campaign. It highlights the importance of developing evidence-informed drug recovery interventions that are appropriate to the Asian culture and to developing economies. Interviews and consultations with users and community stakeholders reveal the need for an intervention that would improve the drug recovery skills and life skills of users. Evidence-based interventions were adapted using McKleroy and colleagues’ (2006) Map of Adaptation Process (MAP) framework. The resulting intervention reflected the country's collectivist culture, relational values, propensity for …

The Winding Road To Relapse: Forging A New Understanding Of Cue-Induced Reinstatement Models And Their Associated Neural Mechanisms, Mark D. Namba, Seven E. Tomek, M. Foster Olive, Joshua S. Beckmann, Cassandra D. Gipson

Psychology Faculty Publications

In drug addiction, cues previously associated with drug use can produce craving and frequently trigger the resumption of drug taking in individuals vulnerable to relapse. Environmental stimuli associated with drugs or natural reinforcers can become reliably conditioned to increase behavior that was previously reinforced. In preclinical models of addiction, these cues enhance both drug self-administration and reinstatement of drug seeking. In this review, we will dissociate the roles of conditioned stimuli as reinforcers from their modulatory or discriminative functions in producing drug-seeking behavior. As well, we will examine possible differences in neurobiological encoding underlying these functional differences. Specifically, we will …

An Analysis Of Personality On Legal Substance And Behavioral Addictions, Elise Stephanie Edwards

Theses, Dissertations and Capstones

This dissertation examined the relationship between personality traits and addiction to legal substances and behaviors. Speranza et al. (2012) found that people who were addicted to illegal substances had similar personality traits, such as impulsivity and sensation-seeking. In addition, substance addiction has also been found to have a relationship with negative affect (Davis, Cohen, Davids, & Rabindranath, 2015). This study applied these findings to addictions of legal substances and behaviors. Caffeine and Internet addiction were specifically analyzed due to their common excessive use in this modern world (Marsh, Snell, Allen, & Wakefield, 2001; Karim & Chaudhri, 2012). Participants were selected …

The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton

Theses and Dissertations--Psychology

Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

The Dichotomous Model Of Substance Abuse: The Elephant In The Room, Shelby Jones

Murray State Theses and Dissertations

Abstract

Addiction can be defined as a repetitive use of a substance or drug that occurs despite any negative outcomes associated with its use. Substance use addiction affects many different areas of an individual’s life, and is often associated with stigma which can result in shame, secrecy, or rejection. There are many theoretical models behind the etiology and maintenance of substance use addiction that include biological, sociological, physiological, and other factors. This investigation examines college-aged individuals’ beliefs about which theoretical model best explains substance use addiction, and if those beliefs can be manipulated when presented with new or opposing information. …

Get Legitimate: Achievements Promote Recovery From Addiction Via Non-Addict Identity, Daniel Crutchfield

UNF Graduate Theses and Dissertations

Abstract

Despite decades of research, over 400 million people around the globe suffer from substance abuse and only 10% to 43% maintain abstinence after treatment. Social support, spirituality, self-regulation, and locus of control have all been examined for their efficacy and relationship with successful abstinence outcomes. Conceptually, educational/vocational achievement is believed to contribute to reforming an identity divorced from the previous lifestyle of active addiction. Educational and Vocational achievements as proxies for non-addict identity have only been investigated sporadically. The present study seeks to establish a quantitative link between successful long-term recovery and these types of goal-oriented achievements. A survey …

Veterans' Stories Of Substance Use, Recovery, And Moral Injury : An Exploratory Study, Chelsea Faria

Theses, Dissertations, and Projects

This explorative/descriptive study investigates veterans’ stories of substance use/misuse, recovery, and moral injury. 12 male veterans participated in semi-structured interviews and answered questions about how their motivations for substance use/misuse and recovery changed prior to, during, and after their military service. Participants were also asked if they experienced moral injury while in the military, and if this precipitated or motivated substance use/misuse. The purpose of this study was to determine how the military impacts a veteran’s substance use/misuse and recovery. Qualitative research on moral injury is minimal, and this study aimed to address that gap in the literature. The study …

Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey

Graduate Dissertations and Theses

Research in animal models and human subjects points towards reward sensitivity and impulsivity as being characteristics that predict greater positive subjective responses to stimulant drugs. The Collaborative Cross (CC) recombinant inbred mouse strains and their inbred founders are a powerful genetic reference panel that has potential as a tool for revealing genetic correlations. The CC/DO founder strains were used to examine the heritability of reward sensitivity and impulsivity traits. Founder strains were tested for activity in an open field, reward sensitivity, and reversal learning (impulsive action) or delay discounting (impulsive choice). Significant heritability for anticipatory responding within the reversal task, …

Intra-Cellular Mechanisms By Which Pac1 Receptor Activation Mediates Stress-Induced Reinstatement To Drug-Seeking, Olivia Miles

Graduate College Dissertations and Theses

The abuse of and addiction to drugs of abuse, such as tobacco, alcohol, opioids, and illicit drugs, are growing global problems that affect the welfare of individuals and societies worldwide. The National Institute of Drug Abuse estimates the annual cost of substance abuse to be over $740 billion in costs related to drug intoxication, withdrawal and relapse. A primary challenge in the treatment of substance abuse is the tendency of users to relapse following acute or extended periods of abstinence; on average over 60% of substance abusers will return to drug use within a year of receiving treatment, many relapsing …

Reliability And Validity Of The Humboldt Food Addiction Questionnaire, Sarah R. Taylor

Cal Poly Humboldt theses and projects

Current research shows that foods high in sugar, salt, and fat can illicit addictive responses (Pursey, Stanwell, Gearhardt, Collins, & Burrows, 2014). Although measures of overeating pathology exist, only a few are dedicated to food addiction. Two of these measures are the Yale Food Addiction Scale (YFAS; Gearhardt, Corbin, & Brownell, 2009b) and the Eating Behaviors Questionnaire (EBQ; Merlo, Klingman, Malasanos, & Silverstein, 2009). Given the shortage of food addiction measures, the Humboldt Food Addiction Questionnaire (HFAQ) was developed to supplement the need for additional tools. Recruited from both a university and online, 626 participants completed this study. Reliability of …

Examining The Roles Of Sex, Methamphetamine, And Degree Of Training In Habit Formation In Rats, Hannah Schoenberg

Graduate College Dissertations and Theses

Addiction is characterized by a progressive loss of executive control over drug-seeking and consumption, and may be associated with a behavioral shift from instrumental goal-directed actions to stimulus-response habits. Sex differences in drug addiction have been linked to changing hormone levels across the estrous cycle, and females exhibit a particular vulnerability to psychostimulants such as cocaine and amphetamines. Psychostimulants and estrogen both influence dopaminergic activity in the dorsal striatum, a region of the brain in which dopamine activity is thought to mediate the shift from action to habit. In the present set of experiments, we examined the roles of sex, …

Characterizing The Role Of Glucocorticoids In The Sign Tracking Behavior Of Male Japanese Quail (Coturnix Japonica), Beth A. Rice

Theses and Dissertations--Psychology

A devastating feature of drug-dependence is the susceptibility of relapse (40-60%) after stretches of abstinence. One theory that may account for relapse suggests that drug cues (e.g., paraphernalia) may increase stress hormones, and this may prompt relapse. Repeatedly pairing a neutral cue with a reward is commonly utilized to measure what subjects learn about a cue that is predictive of reward. Research has shown that animals that attend to a cue more than to the reward (sign trackers) may be more vulnerable to drug addiction. Additionally, research has shown that sign tracking is associated with an increase in corticosterone (CORT), …

The Effect Of Gender And Narcotic Or Stimulant Abuse On Drug-Related Locus Of Control, Yolanda Rene Travis

Walden Dissertations and Doctoral Studies

Substance use disorders cause significant neurological damage, cognitive impairment, and maladaptive behaviors that negatively affect a person's quality of life. The purpose of this study was to explore the effect gender and primary drugs have on locus of control. Generalized expectancy theory helped to explain the behavior of patients diagnosed with substance use disorders and their inability to control ongoing drug use. The research question focused on to what extent drug-related locus of control scores differ by primary drug (narcotic vs. stimulant), gender (male vs. female), and their interaction. Data measuring locus of control from 553 participants provided a subset …
