Common and uncommon risky drinking patterns in young adulthood uncovered by person-specific computational modeling.

Objective: Alcohol use offers social benefits for young adults, but also carries risk of significant negative consequences. Better understanding of processes driving alcohol use for those who experience negative consequences can prevent these harms. These at-risk young adults likely have drinking patterns in common and patterns unique to each individual.

Optimal Instrument Selection using Bayesian Model Averaging for Model Implied Instrumental Variable Two Stage Least Squares Estimators.

Model-Implied Instrumental Variable Two-Stage Least Squares (MIIV-2SLS) is a limited information, equation-by-equation, non-iterative estimator for latent variable models. Associated with this estimator are equation specific tests of model misspecification. One issue with equation specific tests is that they lack specificity, in that they indicate that some instruments are problematic without revealing which specific ones.

Protektem pikinini blong yu trial: protocol for a single arm field trial to assess the effectiveness of treating-all pregnant women with hepatitis B infection with tenofovir prophylaxis to prevent mother-to-child transmission in Vanuatu, 2024-2025.

Background: Hepatitis B infection is a major public health concern in Vanuatu, with approximately 9% of the general population estimated to be living with chronic hepatitis B. Most new infections are due to mother-to-child transmission (MTCT). Hepatitis B vaccination is available in Vanuatu, but coverage rates for first dose within 24 h of birth and third dose are suboptimal.

Daily reciprocal relationships between affect, physical activity, and sleep in middle and later life.

Background: The daily dynamics among affect, physical activity, and sleep are often explored by taking a unidirectional approach. Yet, obtaining a comprehensive understanding of the reciprocal dynamics among affect and health behaviors is crucial for promoting daily well-being.

Purpose: This study examined the reciprocal associations among affect, physical activity, and sleep in daily life in a U.

Structured Estimation of Heterogeneous Time Series.

How best to model structurally heterogeneous processes is a foundational question in the social, health and behavioral sciences. Recently, Fisher et al. introduced the multi-VAR approach for simultaneously estimating multiple-subject multivariate time series characterized by common and individualizing features using penalized estimation.
