Associations Between Cumulative Risk, Childhood Sleep Duration, And Body Mass Index Across Childhood, Tiffany Phu, Jenalee R. Doom

Psychology: Faculty Scholarship

Background: Although associations between cumulative risk, sleep, and overweight/obesity have been demonstrated, few studies have examined relationships between these constructs longitudinally across childhood. This study investigated how cumulative risk and sleep duration are related to current and later child overweight/obesity in families across the United States sampled for high sociodemographic risk.

Methods: We conducted secondary analyses on 3690 families with recorded child height and weight within the Fragile Families and Child Well-Being Study. A cumulative risk composite (using nine variables indicating household/ environmental, family, and sociodemographic risk) was calculated for each participant from ages 3-9 years. Path analyses …

Integration And Segmentation Conflict During Ensemble Coding Of Aspect Ratio, Elric Matthew Elias

Electronic Theses and Dissertations

The visual system often integrates information that "goes together". Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall"). Segmentation allows the visual system to make quick categorical distinctions. Much of the time, integration …

Individual Adjustment As A Predictor Of Improvements In Romantic Relationship Quality From Adolescence To Adulthood, Jamie Novak Shoop

Electronic Theses and Dissertations

Previous work suggests that individuals who experience a poor quality romantic relationship during adolescence are at heightened risk of experiencing poor quality romantic relationships in adulthood. However, this literature has not yet identified factors that may predict which individuals will go on to experience improved romantic relationship quality in adulthood, despite having experienced a poor quality romantic relationship during adolescence. The goal of the current study was to examine whether adolescents' psychosocial adjustment (internalizing and externalizing symptoms, substance use, and self-esteem) predicted improvements in the quality of their subsequent romantic relationships. Data were drawn from a community sample of 200 …

Meta-Analyses Of The Relationship Between Depression And Nine Dimensions Of Perfectionism, Gabriel Lynn Hottinger

Electronic Theses and Dissertations

Perfectionism has been shown to be related to depression, but perfectionism is multidimensional. Some dimensions are related to positive psychological characteristics and outcomes and other dimensions are related to negative psychological characteristics and outcomes. This study reports results of nine meta-analyses performed to investigate the association between each of nine subscales of perfectionism and depression to determine which dimensions of perfectionism are most strongly associated with depression. The two subscales that were used from the Hewitt and Flett (1991b) Multidimensional Perfectionism scale were Self-Oriented Perfectionism (SOP) and Socially-Prescribed Perfectionism (SPP). The five subscales that were used from the Frost et …

Psychometric Investigation Of The Check-In, Check-Out Fidelity Of Implementation Measure, Erin Ann Sullivan

Electronic Theses and Dissertations

Suspension and expulsion are utilized frequently and disproportionality in schools in the United States. Many schools utilize Positive Behavioral Interventions and Supports (PBIS), a tiered framework to prevent problem behavior and reduce the use of discipline practices (Sugai et al., 2000). Check-In, Check-Out (CICO) is a targeted group behavioral intervention that is utilized within this framework in schools to prevent severe problem behavior in students that are beginning to exhibit externalizing and/or internalizing behavioral needs; thus, preventing the use of exclusionary discipline practices (Crone et al., 2010; Hawken & Horner, 2003). As the use of CICO in schools continues to …

Validation Of The Item-Attribute Matrix In Timss-Mathematics Using Multiple Regression And The Lsdm, Lin Ma

Electronic Theses and Dissertations

For many cognitive diagnostic models, the item-attribute matrix (or Q-matrix) is an essential component which displays the relationship between items and their latent attributes or skills in knowledge and cognitive processes. However, it is a challenge to develop an effective Q-matrix.The purposes of this study were (1) to validate of the item-attribute matrix using two levels of attributes (Level 1 attributes and Level 2 sub-attributes), and (2) through retrofitting the diagnostic models to the mathematics test of the Trends in International Mathematics and Science Study (TIMSS), to evaluate the construct validity of TIMSS mathematics assessment by comparing the results of …

Analysis Of The Scale Of Parenting And Life Functioning Using The Rasch Measurement Model, Laricia Longworth-Reed

Electronic Theses and Dissertations

The purpose of the current study was to examine dimensionality, reliability, invariance, targeting, scale use and functioning of items across subgroups for a sample of 278 on the Scale of Parenting and Life Functioning (SPLF). Analysis was conducted using a Rasch partial credit model. Overall, the SPLF showed good overall fit to the model. Unidimensionality of the scale was supported in the analysis, with over 60% of the raw variance explained by the measure. Item fit also provided evidence that the items fit the model. Scale categories displayed clear monotonicity. No differential item functioning was found for mother's age, race/ethnicity, …

Effects Of Societal Norm Manipulation And Presentation Order On Perceived Relationship Satisfaction, Tina Rene Negley

Electronic Theses and Dissertations

While many studies have examined the effects of persuasion on attitudes, few studies have focused on using norms to change perceived satisfaction. This study addressed the need for literature assessing the effects of societal norms on perceived relationship satisfaction. Participants in this study were randomly provided with one of two surveys: one with a set of normative statements regarding an "average couple" that were over-exaggerated, the other with understated norms. Analyses looked to identify whether individuals presented with the high norms were more likely to rate their relationship satisfaction lower, after controlling for demographic and personality characteristics. Hierarchical regression revealed …

Bully/Victim Power Inventory: Measuring The Power Imbalance In The Bully/Victim Relationship, Marybeth Plonkey-Lehto

Electronic Theses and Dissertations

The empirical study of the power imbalance in the bully/victim relationship has impeded research synthesis, and the need for a quantitative measure of this key component has been well established in the literature. Lack of differentiation between victimization with and without power imbalance has been cited as a possible cause for imprecise measurement. Increased precision in bully victimization measurement is needed to accurately inform research investigating psychosocial health, treatment and positive outcomes, in addition to prevention and intervention programs. Therefore, the purpose of this dissertation was the initial development and validation of the Bully/Victim Power Inventory aimed at differentiating perceived …
