Using Irtrees To Account For Response Style Effects Between Item Formats, Stephanie Leroy

Masters Theses, 2020-current

Response styles are consistent person-traits that are defined as the tendency to systematically select responses unrelated to the construct being measured (Paulhus, 1991). Response styles introduce construct-irrelevant variance that distorts observed scores on a measure and biases interpretation of the data. The current study looks at midpoint response style (MRS) and extreme response style (ERS). MRS is the tendency to select the midpoint of a rating scale, while ERS is the tendency to select the endpoints of a rating scale. Previous research sought to either account for response style effects or prevemt them – the current study does both. To …

Double Dosing: Investigating The Utility Of Multiple Priming Questions On Test-Taking Motivation, Mara Mcfadden

Masters Theses, 2020-current

Priming examinees with questions about intended effort prior to testing has been shown to significantly increase examinee expended effort via self-reported effort and response-time effort. However, this question-behavior effect seems to wear off later in a testing session, specifically when a test is given second in the session. I examined whether administering a second “dose” of the question-behavior effect could combat the decrease in examinee effort later in a testing session. To evaluate whether “double dosing” could increase examinee effort later in a testing session, I randomly assigned examinees to one of three question conditions prior to completing two low-stakes …

Attitudes Towards Mental Health, Spiritual Seeking, And Well-Being, David Mitchell

Electronic Theses and Dissertations

Religion plays a crucial role in many peoples’ lives, shaping the way they interact with the world and react to stressors. The Relational Spirituality Model (Sandage & Shults, 2007) posits that individuals’ relationship with God resembles humans’ relationships with one another. That is, relationships consist of intimacy and closeness as well as independence and time away from each other, otherwise known as dwelling and seeking. Previous literature has analyzed the relationship between spiritual coping and well-being, yet none have analyzed the relationship between spiritual seeking and overall well-being using attitudes towards mental health as a moderator. Participants were 84 undergraduate …

College-Related Stress And Substance Use: Experiences Of Honors And Non-Honors Students, Melanie Fischer

Undergraduate Honors Theses

Although there is a wealth of research knowledge related to risk behavior engagement of the general student population, there is less specifically reported about honors students. To address this gap in research, non-honors and honors students were surveyed to determine possible differences in risk behavior engagement. Students were recruited through the East Tennessee State University psychology subject pool and via direct email messages to an honors student-specific listserv. We hypothesized that honors students would have differences in terms of GPA and number of credit hours, endorse more substance use and have more perceived stress compared to non-honors students. The survey …

On The Importance Of Perceived Interpersonal Safety: Antecedents And Consequences Of Living A Subjectively Safe Life, Stylianos Syropoulos

Doctoral Dissertations

The need to be and feel safe is a fundamental human need. Despite extensive theoretical arguments on the subject, and research on relevant concepts, empirical work on what it means to feel interpersonally safe (i.e., in the presence of others or in social environments in general) is scarce. This dissertation presents four investigations that seek to address this gap. It also seeks to highlight the consequences of feeling interpersonally safe for our mental and physical health, and to what degree healthy and high-quality close relationships influence how safe we feel. Chapter 1 is a literature review summarizing theories underlying these …

Many-Facet Rasch Designs: How Should Raters Be Assigned To Examinees?, Christine E. Demars, Yelisey A. Shapovalov, John D. Hathcoat

Department of Graduate Psychology - Faculty Scholarship

In Facets models, raters should be connected, and there are multiple ways to connect raters. Keeping the number of ratings constant and two raters scoring each examinee, the standard error of both rater severity and examinee ability was higher when raters scored one examinee in common with many different raters than when they scored many examinees in common with two raters. However, the differences were small, especially for the standard error of examinee ability. Alternatively, when only a subset of examinees were scored by two or more raters, the smallest standard errors were achieved when all raters scored a common …

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 …

Masterchef Contestant To Social Media Influencer: Do Men And Women Differ In Pursuing Prestige?, Jada Thomas, Robert Deaner

Student Summer Scholars Manuscripts

The male show-off hypothesis claims that men are more likely than women to show off their abilities and publicly compete. However, the male show-off hypothesis has yet to be tested in a domain where both men and women are consistently involved, such as cooking. To examine showing off and cooking, we assessed the social media behavior of MasterChef reality program contestants both in the U.S. and Australia. We focused on 98 contestants from MasterChef U.S. (m = 52 & f = 46) and 107 contestants from MasterChef Australia (m = 45 & f = 62). For each contestant, we examined …

PTSD and suicidality, whereas somatic depression did not. The direct effect …

Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance

Dissertations

Infertility remains one of the most difficult relational contexts for couples. However, some research suggests that some couples actually increase their overall satisfaction in their relationship through infertility due to a deeply shared emotional experience. To the knowledge of the author of this dissertation, no studies exist which explain how couples arrive at their relational outcomes through the experience of infertility. These studies within this dissertation add to the present literature by explaining how couples may arrive at their relational outcome through the lens of Gottman Method Couple Therapy (GMCT). For both studies presented here, 902 participants were recruited through …

Using Bayesian Generalized Structural Equation Modeling To Analyze Latent Agreement, Sydne T. Mccluskey

Dissertations, Theses, and Capstone Projects

Rater comparison analysis is commonly necessary in the social sciences. Conventional approaches to the problem generally focus on calculation of agreement statistics, which provide useful but incomplete information about rater agreement. Importantly, one-number agreement statistics give no indication regarding the nature of disagreements, nor do they distinguish between agreement on presence versus absence of a state or trait. Latent variable models can address both problems, as well as overcoming other well-documented limitations of agreement statistics (e.g., sample dependence, inappropriate population assumptions). Whether raters exactly agree is usually not the question of interest – researchers almost never care whether the difference …

Factor Analysis Of The Financial Strain Index From The Welfare, Children And Families: A Three-City Study, Wave 3, Sally A. Hageman, Ji Hyang Cheon

Journal of Financial Therapy

This paper uses the Welfare, Children, and Families: A Three-City Study data. The three cities included are Boston, Chicago, and San Antonio. The total sample size was n = 1,773, and almost all respondents were female caregivers (99%). An Exploratory Factor Analysis (EFA) on the financial strain index was conducted because previous research reporting an EFA is limited. The financial strain construct was examined using a Principal Component Analysis (PCA) in two Structural Equation Models (SEMs) and a recursive path analysis estimated by ordinary least squares regression. These previous articles provide the theoretical basis for the EFA reported in this …

Confidence Intervals For The Coefficient Alpha Difference From Two Independent Samples (Groups), Miguel Padilla

Psychology Faculty Publications

Four different bootstrap methods for estimating confidence intervals (CIs) for a coefficient alpha difference from two independent samples (groups) were examined. These four CIs were compared to the most promising non-bootstrap CI alternatives in the literature. All CIs were assessed with a Monte Carlo simulation with conditions similar to previous research. The results indicate that there is a clear order in coverage performance of the CIs. The bootstrapped highest density interval had the best coverage performance across all simulation conditions. Yet, it was impacted by unequal sample sizes when one of the groups had the smallest sample size investigated of …

Investigating The Quality Of Life For Children With Autism Spectrum Disorder Scale Using Rasch Methodology, Laura C. Chezan, Jin Liu, Ruiqin Gao, Erik Drasgow

Communication Disorders & Special Education Faculty Publications

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL). The items showed excellent fit to the model and good discriminating ability between low and high QOL. Most items showed a moderate difficulty level. No differential item …

Does Cleft Repair Surgery Restore Normal Visual And Neural Responses To Infant Faces?, Rachael Leanne Kee

Cal Poly Humboldt theses and projects

Infant faces readily capture our attention and elicit enhanced neural processing, likely due to their evolutionary importance in facilitating bonds with caregivers. Infant facial malformations are associated with a lower degree of parental investment and have been shown to negatively impact early infant-caregiver interactions. Cleft lip or cleft palate is a common facial malformation, estimated to affect 1 in 700 live births worldwide, that is associated with altered visual and neural processing as compared to normal infant faces. Importantly, it is not yet known how craniofacial repair surgery impacts responses to these faces. The current study uses eye tracking and …

Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel

Theses and Dissertations (Comprehensive)

There are myriad methods offered in the “self-help industry” and on social media promising to improve happiness. Some messages are evidence-based, often drawn from positive psychology research, and suggest actions requiring time and effort, while other messages may offer feel-good platitudes that are devoid of meaningful guidance; we label this latter type of content “inspirational bullshit.” Across two manuscripts, we investigate the predictors of liking different kinds of positive self-help content, from meaningless randomly-generated phrases to vacuous positivity to evidence-based advice. In the first manuscript, across three studies, bullshit receptivity (a tendency to judge pseudo-profound statements as profound) and people’s …

Efficiently Exploring The Causal Role Of Contextual Moderators In Behavioral Science, Cameron A. Hecht, Carol S. Dweck, Mary Murphy, Kathryn M. Kroeper, David S. Yeager

Psychology Faculty Publications

Behavioral science interventions have the potential to address longstanding policy problems, but their effects are typically heterogeneous across contexts (e.g., teachers, schools, and geographic regions). This contextual heterogeneity is poorly understood, however, which reduces the field's impact and its understanding of mechanisms. Here, we present an efficient way to interrogate heterogeneity and address these gaps in knowledge. This method a) presents scenarios that vividly represent different moderating contexts, b) measures a short-term behavioral outcome (e.g., an academic choice) that is known to relate to typical intervention outcomes (e.g., academic achievement), and c) assesses the causal effect of the moderating context …
