Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

Cumulative effect of multiple health and social factors on adolescent mental well‐being: a cross‐sectional study in Catalonia

open access: yesChild and Adolescent Mental Health, EarlyView.
Background While numerous studies have explored factors contributing to poor mental health, few have examined the combined influence of multiple health and social factors and their cumulative effect. This study specifically aimed to analyze the cumulative effect of multiple health and social factors associated with poor mental well‐being in school‐aged

Mutational Signature‐Based Biomarker for Phase II Trial of Olaparib Maintenance in Advanced High‐Grade Ovarian Cancer

open access: yesCancer Science, EarlyView.
A whole‐exome sequencing–based mutational signature biomarker (MSBM) identified an HRD‐enriched population in advanced ovarian cancer. In a phase II trial, olaparib maintenance suggested clinically meaningful PFS benefit without bevacizumab, supporting MSBM as a complementary HRD assessment approach.

Exploring the Consequences of Parents' Trust and Distrust of Social Workers in Child Welfare Services: Social Workers' Perspectives in Finland

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT In this article, we explore the consequences of parents' trust and distrust of social workers in child welfare services. We collected data via qualitative surveys administered in 2022, to which 29 Finnish social workers responded. We used thematic analysis to identify the key themes of the consequences of trust in our data.
