A latent growth curve model from the perspective of a structural equation model
Latent growth curve modeling (LGCM) is a multivariate technique suited for explaining change over time. In this dissertation, the theoretical background needed to address the specification and estimation of a latent growth curve model from the perspective of a structural equation model (SEM), is …

Handling Missing Data in the Multivariate Growth Curve Model: Comparative Evaluations Using Extensive Simulations
The multivariate growth curve models (GCMs) are generalized multivariate analysis of variance (GMANOVA) models useful in analyzing of longitudinal data, growth curves or other datasets involving response curves. Unlike the MANOVA model and traditional linear models (eg. generalized linear mixed …

Functional Interplay Between Neurocognitive Decline and Risk Factors in Older Adults: A Multivariate Latent Growth Curve Model of Risk
… intervention. The present study employed Latent Growth Curve modeling to longitudinally examine relevant risk factors relationship with neurocognitive functioning via neuropsychological assessment of executive attention, processing speed, episodic memory, language and working memory in 576 …

A Latent Growth Curve Model (LGCM) Analysis of the Relationship Between Five School Climate Dimensions and Retention of Core Subject Secondary Teachers in Georgia
… (2015 – 2020), and a univariate quadratic latent growth curve model was used to estimate school-level teacher retention trajectories and assess the predictive value of school climate over 4 years (2016 – 2019). Grounded in Wang and Degol’s (2016) conceptual framework, five school-level dimensions …

Supporting Self-Beliefs and Intentions in STEM: A Longitudinal Investigation for Math and Science Ability Self-Concepts and STEM Major Intention among High School Students
… on self-concept theories, using a two-level growth curve model to examine the influences of individual, school, and family factors on math and science ability self-concepts and their longitudinal changes. Study 2 was grounded on social cognitive career theory (SCCT) and employed a two-level …

Community Characteristics and Trajectories of Adolescent Internalizing and Externalizing Behaviors: The Cumulative Advantage/Disadvantage and Subjective Appraisals of Social Support as Mechanisms
… primary caregivers. I estimated a two-level growth curve model using three waves of data from the Project on Human Development in Chicago Neighborhoods (PHDCN). Results indicated subjective appraisals of social support by both adolescents and caregivers played a protective role to buffer the …

Assessing psychological changes of gifted students in a residential high school
… the course of an academic year. Using Latent Growth Curve Model (LGM) analysis, the initial level of distress did not impact how students’ stress levels changed over time. The results indicated a strong negative correlation (r =-.884) between the slope and quadratic change; meaning, the more a …

Are There Sex Differences in Behavioral Predictors of Successful Weight Loss Maintenance?
… WL ≥5% WL) at 12 months was determined. A growth curve model assessed interactions of sex and WTLM predictors, and a crisp set qualitative comparative analysis (QCA) characterized individuals' weight changes and behaviors. No sex difference was found in clinically significant WL or in the …

A Three-Factor Model of Personality Predicts Changes in Depression and Subjective Well-Being Following Positive Psychology Interventions
These studies investigated a new model of personality and its relationship to positive psychology interventions. Previous theoretical models and research into the structure of personality has seen disagreement concerning the true number of factors at the basis of personality. Furthermore, the link …

Mirando Hacia el Futuro: Using Multilevel Growth Models to Examine the Achievement Gap Between White and Hispanic Students
… differences in math achievement. A multilevel growth curve model was used to examine the initial levels of, and changes in, achievement for White and Hispanic students within schools and how this varies across schools. In addition, a series of growth models examined trajectories of math …

Can nurture alter nature? The effects of a parenting intervention program on reducing antisocial behaviors
… of the intervention, a parallel process latent growth curve model was utilized to determine whether the rate of change in parenting practices impacted the rate of change in oppositional and problematic behaviors. The hypotheses were partially supported. Only one of the parenting variables, harsh …

A longitudinal behavior genetic model for ordered categorical variables
A model for the analysis of longitudinal twin data consisting of ordered categorical variables was proposed. Proportional changes in response categories across time were modeled within growth curve by means of mean and variance changes in underlying continuous variables. Variances of the growth …

Using Disability Rating Scale Recovery Curves to Predict PASAT Performance After Closed Head Injury
Objective: Existing predictive models of cognitive outcome following closed head injury have been largely based on a single time-point. Using archival data, the current study sought to improve upon existing models by predicting cognitive outcome at six months post-injury from a model of the rate of …
