Collinear Latent Variables in Multilevel Confirmatory Factor Analysis: A Comparison of Maximum Likelihood and Bayesian Estimation
Because variables may be correlated in the social and behavioral sciences, multicollinearity might be problematic. This study investigates the effect of collinearity manipulated in within and between levels of a two-level confirmatory factor analysis by Monte Carlo simulation.
Effectiveness, Mediators, and Effect Predictors of Internet Interventions for Chronic Cancer-Related Fatigue
This paper describes the design and analysis plan that will be used to study 2 Internet interventions aimed at reducing severe fatigue in cancer survivors: a mobile ambulant activity feedback therapy supported through a weekly email by a physiotherapist and a weekly Web- and mindfulness-based cognitive therapy supported online by a psychologist.
Individual and class room predictors of same-cultural friendship preferences in multicultural schools
This study was an investigation of individual and contextual predictors for same-cultural friendship preferences among non-immigrant (n = 125), Turkish (n = 196) and former Yugoslavian (n = 256) immigrant youths (Mage= 14.39 years) in 36 multicultural classes.
Analyzing small data sets using Bayesian estimation: the case of posttraumatic stress symptoms following mechanical ventilation in burn survivors
The analysis of small data sets in longitudinal studies can lead to power issues and often suffers from biased parameter values. These issues can be solved by using Bayesian estimation in conjunction with informative prior distributions.
Latent trajectory studies: the basics, how to interpret the results, and what to report
In statistics, tools have been developed to estimate individual change over time. Also, the existence of latent trajectories, where individuals are captured by trajectories that are unobserved (latent), can be evaluated (Muthén & Muthén, 2000).
Latent Growth Mixture Models to estimate PTSD trajectories
Statistical models to estimate individual change over time and to investigate the existence of latent trajectories, where individuals belong to trajectories that are unobserved (latent), are becoming ever more popular.
Social Influence Interpretation of Interpersonal Processes and Team Performance Over Time Using Bayesian Model Selection
The team behavior literature is ambiguous about the relations between members’ interpersonal processes—task debate and task conflict—and team performance. From a social influence perspective, we show why members’ interpersonal processes determine team performance over time in small groups.
Personality and the Prediction of High-Risk Trajectories of Alcohol Use During Adolescence
Early onset of alcohol use and persistent use of alcohol during adolescence have been associated with later problem behavior, such as heavy drinking and the use of other substances.
Constrained statistical inference: sample-size tables for ANOVA and regression
Researchers in the social and behavioral sciences often have clear expectations about the order/direction of the parameters in their statistical model. For example, a researcher might expect that regression coefficient β1 is larger than β2 and β3.
Experience of traumatic events disrupts measurement invariance of a posttraumatic stress scale
Studies that include multiple assessments of a particular instrument within the same population are based on the presumption that this instrument measures the same construct over time. But what if the meaning of the construct changes over time due to one’s experiences?
Reducing bias due to systematic attrition in longitudinal studies: The benefits of multiple imputation
Most longitudinal studies are plagued by drop-out related to variables at earlier assessments (systematic attrition). Although systematic attrition is often analysed in longitudinal studies, surprisingly few researchers attempt to reduce biases due to systematic attrition, even though this is possible and nowadays technically easy.
The relationship between behavioural problems in preschool children and parental distress after a paediatric burn event
This study examines mother- and father-rated emotional and behaviour problems in and worries about 0- to 5-year-old children at 3 and 12 months after a burn event and the relation with parental distress.
