Distinct trajectories of perinatal depression in Chinese women: application of latent growth mixture modelling [PDF]

BMC Pregnancy and Childbirth, 2022
AbstractBackgroundCurrent research on perinatal depression rarely pays attention to the continuity and volatility of depression symptoms over time, which is very important for the early prediction and prognostic evaluation of perinatal depression. This study investigated the trajectories of perinatal depression symptoms and aimed to explore the factors

Bayesian Inference for Growth Mixture Models with Latent Class Dependent Missing Data [PDF]

Multivariate Behavioral Research, 2011
Growth mixture models (GMMs) with nonignorable missing data have drawn increasing attention in research communities but have not been fully studied. The goal of this article is to propose and to evaluate a Bayesian method to estimate the GMMs with latent class dependent missing data.

A Bayesian Latent Variable Mixture Model for Longitudinal Fetal Growth

Biometrics, 2009
SummaryFetal growth restriction is a leading cause of perinatal morbidity and mortality that could be reduced if high‐risk infants are identified early in pregnancy. We propose a Bayesian model for aggregating 18 longitudinal ultrasound measurements of fetal size and blood flow into three underlying, continuous latent factors.

Smartphone Addiction, Social Support, and Cybercrime Victimization: A Discrete Survival and Growth Mixture Model

Psychosocial Intervention, 2021
In recent decades, criminological theories have identified a set of vulnerabilities in potential victims that seek to explain their victimization. When it comes to explaining cybercrime victimization, however, the important role that addiction to the ...

Predicting development of adolescent drinking behaviour from whole brain structure at 14 years of age [PDF]

, 2019
Adolescence is a common time for initiation of alcohol use and development of alcohol use disorders. The present study investigates neuroanatomical predictors for trajectories of future alcohol use based on a novel voxel-wise whole-brain structural ...

Recovery from open osteocapsular débridement for primary elbow osteoarthritis is rapid and does not depend on preoperative motion

JSES International, 2022
Background and Hypothesis: Osteocapsular débridement is a surgical treatment for functionally limiting primary elbow osteoarthritis (PEOA). We hypothesized that postoperative improvement in range of motion (ROM) following elbow osteocapsular débridement ...

A Multiple-Indicator Latent Growth Mixture Model to Track Courses with Low-Quality Teaching [PDF]

Social Indicators Research, 2019
This paper describes a multi-indicator latent growth mixture model built on the data collected by a large Italian university to track students’ satisfaction over time. The analysis of the data involves two steps: first, a pre-processing of data selects the items to be part of the synthetic indicator that measures students’ satisfaction; the second step

Trajectories of unrealistic optimism in grade expectation: A latent growth mixture model

Social Psychology of Education, 2023
AbstractThis study examined the heterogeneity in temporal shifts of unrealistic optimism (UO) by analyzing students’ grade expectation throughout a semester. UO was defined as the gap between students’ estimated and current course grades, with a larger gap indicating higher UO. Final course grades were viewed as the outcome of UO.
