Frontiers in Psychiatry, 2023 BackgroundWe investigated whether aspects of subjective cognitive aging, including awareness of age-related gains and losses in cognition (AARC-gains, AARC-losses) and subjective cognitive decline (SCD), predict change in objective cognitive function as ...

Latent class growth modelling for the evaluation of intervention outcomes: example from a physical activity intervention [PDF]
Journal of Behavioral Medicine, 2021 AbstractIntervention studies often assume that changes in an outcome are homogenous across the population, however this assumption might not always hold. This article describes how latent class growth modelling (LCGM) can be performed in intervention studies, using an empirical example, and discusses the challenges and potential implications of this ...

Latent trajectory studies: the basics, how to interpret the results, and what to report [PDF]
European Journal of Psychotraumatology, 2015 Background: 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)

Model Fit and Comparison in Finite Mixture Models: A Review and a Novel Approach
Frontiers in Education, 2021 One of the greatest challenges in the application of finite mixture models is model comparison. A variety of statistical fit indices exist, including information criteria, approximate likelihood ratio tests, and resampling techniques; however, none of ...

Evaluation of Analysis Approaches for Latent Class Analysis with Auxiliary Linear Growth Model [PDF]
Frontiers in Psychology, 2018 This study investigated the performance of three selected approaches to estimating a two-phase mixture model, where the first phase was a two-class latent class analysis model and the second phase was a linear growth model with four time points. The three evaluated methods were (a) one-step approach, (b) three-step approach, and (c) case-weight ...

Latent Class Trajectory and Growth Mixture Models in the Study of Physical Resilience [PDF]
Innovation in Aging, 2020 Abstract After a stressor, individuals may experience different trajectories of function and recovery. One potential explanation for this variation is differing trajectories may be indicators of differing classes or levels of resilience to the stressor.

Marginal structural models with Latent Class Growth Modeling of Treatment Trajectories
, 2021 In a real-life setting, little is known regarding the effectiveness of statins for primary prevention among older adults, and analysis of observational data can add crucial information on the benefits of actual patterns of use. Latent class growth models (LCGM) are increasingly proposed as a solution to summarize the observed longitudinal treatment in ...

Evidence of associations between cytokine genes and subjective reports of sleep disturbance in oncology patients and their family caregivers. [PDF]
PLoS ONE, 2012 The purposes of this study were to identify distinct latent classes of individuals based on subjective reports of sleep disturbance; to examine differences in demographic, clinical, and symptom characteristics between the latent classes; and to evaluate ...

Latent classes of nonresponders, rapid responders, and gradual responders in depressed outpatients receiving antidepressant medication and psychotherapy [PDF]
, 2015 BackgroundWe used growth mixture modeling (GMM) to identify subsets of patients with qualitatively distinct symptom trajectories resulting from treatment. Existing studies have focused on 12-week antidepressant trials.

Trajectories of university adjustment in the United Kingdom: Emotion management and emotional self-efficacy protect against initial poor adjustment [PDF]
, 2013 Little is known about individual differences in the pattern of university adjustment. This study explored longitudinal associations between emotional self-efficacy, emotion management, university adjustment, and academic achievement in a sample of first ...
