Presentation about GRoLTS-Checklist

At the Meeting of the Working Group SEM (16 and 17 March 2017; Ghent, Belgium) I will present about the Guidelines for Reporting on Latent Trajectory Studies.

March 16 at 14:15-14:45

Abstract: Estimating models within the mixture model framework, like Latent Growth Mixture Modeling (LGMM) or Latent Class Growth Analysis (LCGA), involves making various decisions throughout the estimation process. This has led to a high variety of how results of latent trajectory analysis are reported. To overcome this issue, using a four-round Delphi study, we developed Guidelines for Reporting on Latent Trajectory Studies (GRoLTS). The purpose of GRoLTS is to present criteria that should be included when reporting the results of latent trajectory analysis across research fields. We have gone through a systematic process to identify key components that, according to a panel of experts, are necessary when reporting results for trajectory studies. We applied GRoLTS to 38 papers where LGMM/LCGA was used to study trajectories of post-traumatic stress after a traumatic event.
