Network state dynamics underpin basal craving in a transdiagnostic population.
Mol Psychiatry
February 2025
Interdepartmental Neuroscience Program, Yale School of Medicine, New Haven, CT, USA.
Emerging fMRI methods quantifying brain dynamics present an opportunity to capture how fluctuations in brain responses give rise to individual variations in affective and motivation states. Although the experience and regulation of affective states affect psychopathology, their underlying time-varying brain responses remain unclear. Here, we present a novel framework to identify network states matched to an affective experience and examine how the dynamic engagement of these network states contributes to this experience.

Desire thinking, within the metacognitive model of addictive behaviors, is conceptualized as a transdiagnostic process linked to the escalation and maintenance of craving for various addictive disorders; however, its application to the understanding of gambling and the Chinese community remains at an early stage. The present study aimed to introduce desire thinking into gambling research in the Chinese context by: (1) testing the applicability of its two-factor conceptualization and assessment tool, the Desire Thinking Questionnaire (DTQ), and (2) exploring its association with dysregulated and regulated engagements in gambling (i.e.

Background: Delay discounting quantifies an individual's preference for smaller, short-term rewards over larger, long-term rewards and represents a transdiagnostic factor associated with numerous adverse health outcomes. Rather than a fixed trait, delay discounting may vary over time and place, influenced by individual and contextual factors. Continuous, real-time measurement could inform adaptive interventions for various health conditions.

Introduction: The transdiagnostic approach has been shown to offer promising prospects in psychopathology, based on the observation that common factors may be involved in different psychiatric disorders. The transdiagnostic skills scale (T2S) was developed recently to assess the skills that are disrupted in these disorders. However, studies have shown that the T2S has lower predictive power for externalizing than internalizing disorders.

Compared to their male counterparts, women with alcohol use disorders (AUD) alone and those with symptoms of co-occurring emotional disorders (posttraumatic stress disorder, PTSD, and depression) are particularly likely to have increased alcohol craving in response to negative affect and daily stressors. Emotion dysregulation is one transdiagnostic construct that may underlie heightened craving in response to stress within this population. In a secondary data analysis, the current study examined emotion dysregulation as a mediator of the associations of posttraumatic stress symptoms (PTSS) and depression symptoms with heightened stress-induced alcohol craving, as measured in the lab.
