Stress And Stressors Affecting Latino Migrant Dairy Farmworkers In Vermont: An Exploratory Analysis, Virginia Kades

Graduate College Dissertations and Theses

Vermont is a largely rural and homogenous New England state not often thought of as a destination for Latino migrant farm laborers, but in recent years dairy farms have begun hiring Latino workers; there are now an estimated 1200 in the state, although the exact number is unknown (Baker, 2013). As the dairy industry is the largest contributor to sales from agriculture for the state, these farmworkers play an essential role in Vermont’s economy (U.S. Department of Agriculture, 2014b). These migrant dairy farmworkers hail primarily from Mexico, with a small fraction from Central America, and lack sufficient documentation to work …

Comparing Family Planning Knowledge Among Females And Males Receiving Opioid Agonist Treatment Or Seeking Primary Care Services, Heidi S. Melbostad

Graduate College Dissertations and Theses

Background: Approximately 70% of US adults currently receiving opioid agonist treatment (OAT) for opioid use disorder are of reproductive age. Among women receiving OAT at risk of having an unintended pregnancy, typically less than half report any current contraceptive use compared to 90% in the general population. In addition, the rate of unintended pregnancy among women receiving OAT is disproportionately higher than the general population (~80% vs. 45%, respectively). Lack of knowledge about family planning may be contributing to decreased rates of contraceptive use and increased rates of unintended pregnancy among women receiving OAT.

Method: Participants were a convenience sample …

Examining The Malleability Of Cigarette Product Preference, Danielle Rose Davis

Graduate College Dissertations and Theses

Introduction: Cigarette preference increases as a function of nicotine content, but preference can be shifted by manipulating cigarette cost. The aim of the present study is to model whether the behavioral-economic metric of unit price (cigarette cost/nicotine content) accounts for cigarette preference shifts and whether preference changes to very low nicotine content cigarettes (VLNCs) are associated with corresponding changes in smoking rate.

Methods: 169 daily smokers from populations vulnerable to smoking completed sessions in which choices between smoking normal nicotine content (NNC) (15.8mg/g) and VLNC (0.4mg/g) cigarettes were concurrently available. In Condition 1, choices for both products were available ad-lib …

The Structure Of Parent-Child Coping Interactions As A Predictor Of Adjustment In Middle Childhood: A Dynamic Systems Perspective, Sarah Budney Stanger

Graduate College Dissertations and Theses

This study applied a contemporary dynamic systems methodology (state space grids) to examine how the structure of parent-child coping interactions, above and beyond the content of such interactions, influences adjustment (i.e., internalizing problems, externalizing problems, and coping efficacy) over time in middle childhood. A community sample of children (N = 65) completed a stressful laboratory task with a parent present, during which parent and child behavior were observed. Parent behavior during the task was coded using a socialization of coping framework. Parents' verbal suggestions to their child about how to cope with the stressful task were coded as primary control …

Referral Patterns And Service Provision In Child Protective Services: Child, Caregiver, And Case Predictors, Hannah Mead Holbrook

Graduate College Dissertations and Theses

Child maltreatment, and recurrent maltreatment in particular, occurs at an alarmingly high rate. Frequency of reports to Child Protective Services (CPS) is associated with negative psychological outcomes, and children whose reports are unsubstantiated experience similar risk of behavioral, emotional, and substance use disorders as those whose reports are substantiated. Prior research has demonstrated that children with no CPS reports and children with one CPS report showed no significant differences in rates of maltreatment perpetration or substance use in adulthood, suggesting that prevention efforts after one report may have strong merit in reducing negative outcomes in adulthood. However, patterns and risk …

A Randomized Trial To Compare Switching To Very Low Nicotine Content Cigarettes Versus Reducing Cigarettes Per Day, Elias Mushabac Klemperer

Graduate College Dissertations and Theses

Smoking cigarettes is the most preventable cause of death in the US. Smokers are often unsuccessful at quitting because they are dependent. Reducing nicotine could be one way to reduce dependence. Currently, reducing cigarettes per day (CPD) is the most common strategy to reduce nicotine intake. However, some have proposed switching to very low nicotine content (VLNC) cigarettes to reduce nicotine and dependence. Both reducing CPD and switching to VLNC cigarettes aim to reduce nicotine but do so in different ways. I conducted a randomized trial to compare the degree to which switching to VLNC cigarettes vs reducing CPD 1) …

Biobehavioral Predictors Of Cannabis Use In Adolescence, Philip Aaron Spechler

Graduate College Dissertations and Theses

Cannabis use initiated during adolescence may precipitate lasting consequences on the brain and behavioral health of the individual. However, research on the risk factors for cannabis use during adolescence has been largely cross-sectional in design. Despite the few prospective studies, even less is known about the neurobiological predictors. This dissertation improves on the extant literature by leveraging a large longitudinal study to uncover the predictors of cannabis use in adolescent samples collected prior to exposure. All data were drawn from the IMAGEN study and contained a large sample of adolescents studied at age 14 (N=2,224), and followed up at age …

Risk Profiles For Adolescent Internalizing Problems, Kelsey Elizabeth Hudson

Graduate College Dissertations and Theses

Objective: Internalizing problems are commonly diagnosed during adolescence, and are associated with distress, impairment, and negative mental health outcomes in adulthood. Thus, there is a critical need to characterize adolescents who are at the highest risk for escalating to clinical levels of internalizing problems while extending current literature and incorporating both biological and environmental predictors. This study aimed to characterized risk profiles for fourteen-year-old adolescents who developed clinical levels of internalizing (High Internalizing [HI]) problems by age nineteen, using brain, genetic, personality, cognitive, life history, psychopathology, and demographic measures. The study also examined whether there were functional and structural brain …

Risk Factors For Suicidal Behavior Among Bhutanese Refugees Resettled In The United States, Jonah Meyerhoff

Graduate College Dissertations and Theses

Suicidal behavior and death by suicide are significant and pressing problems in the Bhutanese refugee community. Currently, Bhutanese refugees are dying by suicide at a rate nearly 2 times higher than the general United States population. Proper identification of risk factors for suicide saves lives and prevents suicides (Mann et al., 2005); however, if suicide risk is underestimated due to culturally inflexible risk assessments, preventable deaths may continue to needlessly grow. In a community sample of Bhutanese refugees resettled in Vermont (N=60), the current study aims to (1) test elements of a comprehensive conceptual model of incremental risk factors for …

Happily Arguing: The Role Of Parental Positive Emotions During Interparental Conflict On Child Functioning, Hannah Childs Woolfolk

Graduate College Dissertations and Theses

Research is lacking regarding the role of positive emotions expressed by parents during interparental conflict (IPC) on child functioning. This study examined the relationship between parents’ expressions of positive emotions (PE) during IPC and child functioning. Child functioning measures included children’s feelings of happiness during an IPC laboratory task between their parents, cognitions regarding IPC in the home, feelings of emotional security in the marital system, and psychological adjustment (i.e., internalizing and externalizing behaviors, and depression). In addition, this study tested whether PE predicted these measures of child functioning above and beyond conflict resolution, and whether child temperamental surgency moderated …

Can Perspective Taking Lead To Prejudice And Discrimination?, James Joseph Hodge

Graduate College Dissertations and Theses

Research on perspective taking generally points to positive outcomes, but a small and growing body of literature highlights conditions where perspective taking can instead lead to undesirable outcomes. The goal of this dissertation study is to test a model of how taking the perspective of someone who struggles to control food consumption may negatively influence prejudice and discrimination toward heavy people. My model predicts that taking the perspective of someone who is effortfully trying not to eat, which requires the use of self-regulatory processes, vicariously depletes the perspective-taker’s own self-regulatory capacity. Whether that depletion leads to greater expressions of prejudice …

Contextual Control Of Instrumental Actions And Habits Following Retroactive Interference, Michael Steinfeld

Graduate College Dissertations and Theses

It is commonly accepted that instrumental responses that have been extinguished can return. For example, in a phenomenon known as the renewal effect, extinguished behaviors return upon removal from the extinction context. Another well-accepted notion is that instrumental behaviors can be thought of as goal-directed actions, which form over the course of moderate amounts of practice or training, and habits, which form after extended practice. Despite years of research on both topics, what happens to actions and habits following extinction is poorly understood. The present experiments examined the renewal of actions and habits following retroactive interference paradigms such as extinction …

The Role Of The Prelimbic, Infralimbic, And Cerebellar Cortices In Operant Behavior, Megan Laura Shipman

Graduate College Dissertations and Theses

Operant (instrumental) conditioning is a laboratory method for investigating voluntary behavior and involves training a particular response, such as pressing a lever, to earn a reinforcer. Operant behavior is generally divided into two categories: actions and habits. Actions are goal-directed and controlled by response-outcome (R-O) associations. Habits are stimulus-driven and controlled by stimulus-response associations (S-R). Behavior is determined to be goal-directed or habitual by whether or not it is sensitive (action) or insensitive (habit) to reinforcer/outcome devaluation. Many brain regions have been linked to the learning and/or expression of actions and/or habits. This dissertation investigates a few different brain regions …

Parsing Heterogenity In Non-Episodic, Pediatric Irritability: A Transdiagnostic, Research Domain Criteria Informed Approach, Merelise Rose Ametti

Graduate College Dissertations and Theses

Background: Approximately 7% of clinically referred youth exhibit profound impairment in the ability to regulate their affect, behavior, and cognition. This phenotype – often referred to as dysregulation – has been associated with a multitude of negative outcomes. Symptom overlap between dysregulation and other psychological disorders has generated debate regarding whether DP constitutes a distinct syndrome characterized by intense, persistent irritability or is merely the combination of symptoms from disruptive or mood disorders. In order to elucidate this question, the current study examined the transdiagnostic continuities and discontinuities in three RDoC constructs (frustrative non-reward, acute threat, and cognitive control) proposed …

Validation Of The Triarchic Model Of Psychopathy In Youth, Andrew Douglas Gill

Graduate College Dissertations and Theses

Psychopathic personality traits are prominent risk factors for persistent and severe expressions of antisocial behavior in youth. Historically, psychopathy in youth has been assessed via the psychopathy checklist (PCL) model, which indexes specific antisocial indicators such as past cruelty to others and reckless irresponsibility. Although it is known that these behaviors can identify a subgroup of delinquent males who are at high risk to engage in antisocial behavior, there is concern that content overlap between the behavioral indicators of the psychopathy construct and its behavioral outcomes accounts for too much variance in prediction. This overlap limits the validity of the …

Predictors Of Psychotherapy Attrition Among Refugees, Emily Robin Pichler

Graduate College Dissertations and Theses

It is estimated that approximately one in five patients will terminate therapy early, before participating in full treatment and obtaining maximum therapeutic benefits. Millions of people are forcibly displaced as refugees each year, and therefore at increased risk for poverty, discrimination, and complex mental health needs, yet no research has yet examined rates or predictors of psychotherapy attrition among refugees. The current study draws upon a sample of refugee clients seeking treatment at a community clinic (N = 196), and a comparison group of 165 non-refugee clients at the same clinic. Logistic regression was employed to (1) compare rates of …
