Graduate And Undergraduate Quantitative Education In Psychology In The United States: A Mixed Methods Approach, Abby L. Braitman, James M. Henson
Graduate And Undergraduate Quantitative Education In Psychology In The United States: A Mixed Methods Approach, Abby L. Braitman, James M. Henson
Psychology Faculty Publications
Quantitative methodology is part of the core curriculum for training in psychology and is required of graduate students across all subdisciplines; as such, the depth and breadth of course content is a universal issue among psychology training programs. Required and supplemental quantitative content is constantly evolving with the development of new techniques or applications. Therefore, the purpose of this inquiry was fourfold; we aimed to (1) describe the current state of undergraduate quantitative education and establish a common set of current undergraduate curricular topics; (2) characterize graduate quantitative education in terms of required coursework, optional coursework, and omitted topics; (3) …
Exploring Healthcare Chatbot Information Presentation: Applying Hierarchical Bayesian Regression And Inductive Thematic Analysis In A Mixed Methods Study, Samuel Nelson Koscelny
Exploring Healthcare Chatbot Information Presentation: Applying Hierarchical Bayesian Regression And Inductive Thematic Analysis In A Mixed Methods Study, Samuel Nelson Koscelny
All Theses
High blood pressure, also known as hypertension, significantly increases the risk of heart disease and stroke, which are leading causes of death in the United States. While contributing to over 691,000 deaths in 2021 alone in the United States (U.S.), it also imposes immense economic burden on the healthcare system, costing approximately $131 billion annually. One way to address this issue is for increased self-care behaviors and medication adherence, both of which require sufficient health literacy. Despite the importance of health literacy, 90% of U.S. adults struggle with health-related subjects. Overcoming the issues associated with health literacy requires addressing the …
Recentering Psych Stats, Lynette Bikos
Recentering Psych Stats, Lynette Bikos
Faculty Open Access Books
To center a variable in regression means to set its value at zero and interpret all other values in relation to this reference point. Regarding race and gender, researchers often center male and White at zero. Further, it is typical that research vignettes in statistics textbooks are similarly seated in a White, Western (frequently U.S.), heteronormative, framework. ReCentering Psych Stats seeks to provide statistics training for psychology students (undergraduate, graduate, and post-doctoral) in a socially and culturally responsive way. All lessons use the open-source statistics program, R (and its associated packages). Each chapter includes a screencast lesson, features a workflow …
Towards Scalable Mental Health: Leveraging Digital Tools In Combination With Computational Modeling To Aid In Treatment And Assessment Of Major Depressive Disorder, Matthew D. Nemesure
Towards Scalable Mental Health: Leveraging Digital Tools In Combination With Computational Modeling To Aid In Treatment And Assessment Of Major Depressive Disorder, Matthew D. Nemesure
Dartmouth College Ph.D Dissertations
Major depressive disorder (MDD) is a debilitating disorder that impacts the lives of nearly 280 million individuals worldwide, representing 5% of the overall adult population. Unfortunately, these statistics have been both trending upward and are also likely an underestimate. This can be primarily attributed to lack of screening paired with a lack of providers. Worldwide, there are roughly 450 individuals living with MDD per mental health care provider. Adding to this burden, approximately half of affected individuals that do receive care of any kind will fail to remain in remission. The goal of this thesis work is to leverage statistical …
A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot
Graduate Theses, Dissertations, and Problem Reports (ETD)
Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …
Marginal Mediation Analysis: A New Framework For Interpretable Mediated Effects, Tyson S. Barrett
Marginal Mediation Analysis: A New Framework For Interpretable Mediated Effects, Tyson S. Barrett
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Mediation analysis is built to answer not only if one variable affects another, but how the effect takes place. However, it lacks interpretable effect size estimates in situations where the mediator (an intermediate variable) and/or the outcome is categorical or otherwise non-normally distributed. By integrating a powerful approach known as average marginal effects within mediation analysis—termed Marginal Mediation Analysis (MMA)—the issues regarding categorical mediators and/or outcomes are, in large part, resolved. This new approach allows the estimation of the indirect effects (those effects of the predictor that affect the outcome through the mediator) that are interpreted in the same way …
The Reliability Of Crowdsourcing: Latent Trait Modeling With Mechanical Turk, Matt Baucum, Steven Rouse Dr., Cindy Miller-Perrin, Elizabeth Mancuso Dr.
The Reliability Of Crowdsourcing: Latent Trait Modeling With Mechanical Turk, Matt Baucum, Steven Rouse Dr., Cindy Miller-Perrin, Elizabeth Mancuso Dr.
Seaver College Research And Scholarly Achievement Symposium
Mechanical Turk, an online crowdsourcing platform, has recently received increased attention in the social sciences as studies continue to suggest its viability as a source for reliable experimental data. Given the ease with which large samples can be quickly and inexpensively gathered, it is worth examining whether Mechanical Turk can provide accurate experimental data for methodologies requiring such large samples. One such methodology is Item Response Theory, a psychometric paradigm that defines test items by a mathematical relationship between a respondent’s ability and the probability of item endorsement. To test whether Mechanical Turk can serve as a reliable source of …
Statistical Analyses Of The Resilience Function, Joseph W. Houpt, Daniel R. Little
Statistical Analyses Of The Resilience Function, Joseph W. Houpt, Daniel R. Little
Psychology Faculty Publications
The extent to which distracting information influences decisions can be informative about the nature of the underlying cognitive and perceptual processes. In a recent paper, a response time-based measure for quantifying the degree of interference (or facilitation) from distracting information termed resilience was introduced. Despite using a statistical measure, the analysis was limited to qualitative comparisons between different model predictions. In this paper, we demonstrate how statistical procedures from workload capacity analysis can be applied to the new resilience functions. In particular, we present an approach to null-hypothesis testing of resilience functions and a method based on functional principal components …

A Preliminary Investigation Of The Validity Of Time-Based Measures Of Sustained Attention For Children, Michael R. Kulfan
A Preliminary Investigation Of The Validity Of Time-Based Measures Of Sustained Attention For Children, Michael R. Kulfan
Antioch University Dissertations & Theses
This study is a preliminary investigation of the validity of using time-based measures to quantify sustained attention in children ages 6-12. Problems with sustained attention negatively affect childhood learning and development. The prevalence of disorders known to impact sustained attention performance continue to rise in the United States. Currently, commercially available, objective measures of sustained attention use normative comparisons that provide limited information about the effect such problems have on child performance in natural settings. We reviewed test data from 290 charts of children ages 6-12 referred for neuropsychological evaluation. The Test of Everyday Attention for Children (TEA-Ch) is an …
