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.
Costs and Benefits of Bullying in the Context of the Peer Group: A Three Wave Longitudinal Analysis
Whereas previous research has shown that bullying in youth is predictive of a range of negative outcomes later in life, the more proximal consequences of bullying in the context of the peer group at school are not as clear. The present three-wave longitudinal study followed children (N = 394; 53 % girls; Mage = 10.3 at Time 1) from late childhood into early adolescence.

The construct of coherence as an indicator of attachment security in middle childhood: The Friends and Family Interview, New York, NY: Guilford Press), a semi-structured interview assessing attachment representations, is used in the context of an international research project.
Testing informative hypotheses in SEM increases power: An illustration contrasting classical hypothesis testing with a parametric bootstrap approach
In the present paper, the application of a parametric bootstrap procedure, as described by van de Schoot, Hoijtink, and Deković (2010), will be applied to demonstrate that a direct test of an informative hypothesis offers more informative results compared to testing traditional null hypotheses against catch-all rivals.
