Multilevel modeling of item position Effects
… hierarchical generalized linear model, a type of multilevel model, for estimating item position effects. Previous approaches to estimating and modeling position effects are described within a multilevel framework, and an extension of these approaches is demonstrated, one which incorporates item …

Built Environment and Risk of Obesity in the United States: A Multilevel Modeling Approach
… fallacy, the second study used a multi-level modeling (MLM) approach by accounting for individual attributes such as demographic, socioeconomic and behavior variables. Furthermore, models for areas of different urbanicity levels were tested. The national study found that obesity risk initially …

The Expanding Definition of Crime and Its Effect on the Individual: A Multilevel Modeling Analysis
… in incarceration rates.</p> <p>Hierarchical modeling was used to test hypotheses about the influence of the PSI, the PPI, and other state-level contextual variables on sentence length. At the individual level, the model suggests the race of the inmate has some, though nonsignificant, …

Analysis of affective instability on ecological momentary assessments data: successive difference, variance decomposition, and mean comparison via multilevel modeling
… these measures be analyzed within generalized multilevel models. An illustrative example using EMA data on negative mood for borderline personality disorder (BPD) and major depressive disorder (MDD) groups is presented which shows that MSSD and PAC capture affective instability better than …

Multilevel Modeling as an Analytic Tool for Evaluation of Excellence and Equity of Student Outcomes in Standards-Based Reform
… to guide deliberation and decision making, and multilevel modeling appears to be an analytic tool for evaluators that is well-matched to these needs of standards-based reform in education.

Characteristics of Perceived Social Networks of Middle-Aged and Older Kenyan Women with and without HIV: A Multilevel Modeling Study
… collected ego and alter characteristics. Two multilevel models for clustered data were fitted for each outcome: unadjusted models included only the ego's HIV status as the main predictor, while adjusted models included HIV status and potential confounding variables. An exploratory analysis …

Implications of Interactions Among Society, Education and Technology: A Comparison of Multiple Linear Regression and Multilevel Modeling in Mathematics Achievement Analyses
… teacher certification. In the second approach---multilevel modeling with students as the level-1 unit of analysis and teachers as the level-2 unit of analysis---student characteristics are significant predictors of math achievement, and teacher characteristics are insignificant predictors. The …

A Longitudinal Examination of the Influences of Family Processes and Demographic Variables on Adolescent Weight
… the data are non-independent. Longitudinal multilevel modeling was used to adjust for this non-independence. The final model indicated that frequency of family meals, sex, race, father's parenting style, control, and mother's BMI were important predictors of adolescent BMI percentile over …

Effect of Air Carrier Restructuring Strategies on Post-bankruptcy Performance
… and practical contributions.</p> <p>A multilevel exploratory factor analysis was conducted to explore whether the same restructuring areas were found in air carrier specific metrics. All four restructuring areas were found in the factor analysis. Next, multilevel modeling was conducted …

An evaluation of parameter estimation when using multilevel structural equation modeling for mediation analysis
… or nested data structures requires the use of multilevel modeling techniques. One such multilevel modeling technique is multilevel structural equation modeling (MLSEM). While estimation of indirect effect parameters and standard errors based on the conventional multilevel model (MMM) has been …

Income Inequality and Prejudice in the US
… impact intergroup relations in the US? I used a multilevel modeling approach to test the effects of income inequality on attitudes toward US minority groups from the American Election Studies, from 1970-2008. Rising income inequality as measured by Gini predicted prejudice towards African …

The robustness of multilevel multiple imputation for handling missing data in hierarchical linear models
… about the proper way to handle missing data in multilevel data structures. This study used a Monte Carlo simulation to compare the performance of three missing data methods on multilevel data (multilevel multiple imputation, multiple imputation ignoring the multilevel structure, and listwise …

Multi-level Model of Parent-Child Attachment, Depression & Self-Concept in Pediatric Chronic Illness
… Drawing data from 50 MEND participants, we used multilevel modeling techniques to test changes in self-concept over time as predicted by number of weeks in MEND, depression, family cohesion and flexibility, and baseline levels of maternal and paternal attachment. Results: At Level 1, depression …
