With the recent development of easy-to-use tools for Bayesian analysis, psychologists have started to embrace Bayesian hierarchical modeling. Bayesian hierarchical models provide an intuitive account of inter- and intraindividual variability and are particularly suited for the evaluation of repeated-measures designs. Here, we provide guidance for model specification and interpretation in Bayesian hierarchical modeling and describe common pitfalls that can arise in the process of model fitting and evaluation. Our introduction gives particular emphasis to prior specification and prior sensitivity, as well as to the calculation of Bayes factors for model comparisons. We illustrate the use of state-of-the-art software programs Stan and brms. The result is an overview of best practices in Bayesian hierarchical modeling that we hope will aid psychologists in making the best use of Bayesian hierarchical modeling.

To develop a method leveraging hospital-based surveillance to estimate influenza-related hospitalizations by state, age, and month as a means of enhancing current US influenza burden estimation efforts. Using data from the Influenza Hospitalization Surveillance Network (FluSurv-NET), we extrapolated monthly FluSurv-NET hospitalization rates after adjusting for testing practices and diagnostic test sensitivities to non-FluSurv-NET states. We used a Poisson zero-inflated model with an overdispersion parameter within the Bayesian hierarchical framework and accounted for uncertainty and variability between states and across time.

January 2025
Scripps Institution of Oceanography, San Diego, California, USA.
Background: The increasing frequency and severity of extreme heat events due to climate change present unique risks to children and adolescents. There is a lack of evidence regarding how heat's impacts on pediatric patients vary spatially and how structural and sociodemographic factors drive this heterogeneity.
Objectives: We examined the association between extreme heat events and pediatric acute care utilization in California for 19 distinct health conditions.
Noisy-channel language comprehension in aphasia: A Bayesian mixture modeling approach.
Psychon Bull Rev
January 2025
Boston University, Boston, USA.
Individuals with "agrammatic" receptive aphasia have long been known to rely on semantic plausibility rather than syntactic cues when interpreting sentences. In contrast to early interpretations of this pattern as indicative of a deficit in syntactic knowledge, a recent proposal views agrammatic comprehension as a case of "noisy-channel" language processing with an increased expectation of noise in the input relative to healthy adults. Here, we investigate the nature of the noise model in aphasia and whether it is adapted to the statistics of the environment.

Division of Rheumatology, Allergy and Immunology, Department of Medicine, University of Cincinnati College of Medicine, Cincinnati, OH, USA.
Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.
Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.
Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.
Care Recipients' Cognitive Trajectories and Caregivers' Depressive Symptoms: The Mediating Role of Caregiving Burden.
Gerontologist
January 2025
Department of Sociology, Yale University, 493 College Street, New Haven, CT, 06511, USA.
Background And Objectives: The heterogeneity of population-based trajectories of care recipients' (CRs) cognitive functioning and how they are associated with their caregivers' mental health is less studied in the United States. Informed by the stress process model, this study examines the relationship between care recipients' cognitive trajectories and caregivers' depressive symptoms, and the mediating role of caregiving burden.
Research Design And Methods: Data were from the National Health and Aging Trends Study (2011-2020) for 1,086 care recipients and their 1,675 caregivers from the 2021 National Study of Caregiving.
