Rethinking Group Differences in Psychopathology Networks: A Slow-Fast Perspective on Context and Symptom Activation
Kyuri Park, Denny Borsboom, Mike Lees +6
Groups differing in social and economic circumstances often differ markedly in depressive symptom levels, yet their estimated symptom networks show few clear differences. Such null…
Slow Context, Fast Symptoms: Multiscale Temporal Dynamics and Context-Induced Coupling in Psychological Systems
Kyuri Park, Denny Borsboom, Mike H. Lees +3
Psychological dynamics unfold across multiple timescales: symptoms and other psychological states can change rapidly, whereas social, environmental, biological, and developmental c…
Causal Behavioral Evaluation of AI Agents at Scale via Automated Behavioral Science
Soo Yong Lee, Jongha Lee, Jaewan Chun +8
As AI agents are increasingly deployed in complex and new environments, knowing the conditions that influence their behavior becomes an indispensable step for their reliable and sa…
Emergence of psychopathological computations in large language models
Soo Yong Lee, Hyunjin Hwang, Taekwan Kim +5
Can large language models (LLMs) instantiate computations of psychopathology? In this work, we establish a computational-theoretical framework to provide an account of psychopathol…
Quantifying agent impacts on contact sequences in social interactions
Mark M. Dekker, Tessa F. Blanken, Fabian Dablander +3
Human social behavior plays a crucial role in how pathogens like SARS-CoV-2 or fake news spread in a population. Social interactions determine the contact network among individuals…
Measurement error and reliability from a different perspective: Reliability of decision functions and the sum score
Lourens Waldorp, Maarten Marsman, Denny Borsboom
We propose an alternative framework for measurement error that allows us to determine reliability at the level of the decision, such as the decision to pass or fail. This framework…
Moderated Network Models
Jonas Haslbeck, Denny Borsboom, Lourens Waldorp
Pairwise network models such as the Gaussian Graphical Model (GGM) are a powerful and intuitive way to analyze dependencies in multivariate data. A key assumption of the GGM is tha…
A Network Perspective on Attitude Strength: Testing the Connectivity Hypothesis
Jonas Dalege, Denny Borsboom, Frenk van Harreveld +1
Attitude strength is a key characteristic of attitudes. Strong attitudes are durable and impactful, while weak attitudes are fluctuating and inconsequential. Recently, the Causal A…
Network Structure Explains the Impact of Attitudes on Voting Decisions
Jonas Dalege, Denny Borsboom, Frenk van Harreveld +2
Attitudes can have a profound impact on socially relevant behaviours, such as voting. However, this effect is not uniform across situations or individuals, and it is at present dif…
The Gaussian Graphical Model in Cross-sectional and Time-series Data
Sacha Epskamp, Lourens J. Waldorp, René Mõttus +1
We discuss the Gaussian graphical model (GGM; an undirected network of partial correlation coefficients) and detail its utility as an exploratory data analysis tool. The GGM shows…
Network Psychometrics
Sacha Epskamp, Gunter K. J. Maris, Lourens J. Waldorp +1
This chapter provides a general introduction of network modeling in psychometrics. The chapter starts with an introduction to the statistical model formulation of pairwise Markov r…
Major depression as a complex dynamic system
Angélique O. J. Cramer, Claudia D. van Borkulo, Erik J. Giltay +4
In this paper, we characterize major depression (MD) as a complex dynamical system in which symptoms (e.g., insomnia and fatigue) are directly connected to one another in a network…
Generalized Network Psychometrics: Combining Network and Latent Variable Models
Sacha Epskamp, Mijke Rhemtulla, Denny Borsboom
We introduce the network model as a formal psychometric model, conceptualizing the covariance between psychometric indicators as resulting from pairwise interactions between observ…
Estimating Psychological Networks and their Accuracy: A Tutorial Paper
Sacha Epskamp, Denny Borsboom, Eiko I. Fried
The usage of psychological networks that conceptualize psychological behavior as a complex interplay of psychological and other components has gained increasing popularity in vario…
