Eg, if someone always has low values for emotion and impulsivity, with a person-specific cutoff of 85%, they would still have 15% “intense” values even though they never reported truly intense emotion/impulsivity. It would also be cool to look at different thresholds for emotion and impulsivity.

Janan Mostajabi @jananmost.bsky.social · 16/05/2025
Thank you! In our exploratory analyses in the first sample (the other five were preregistered), we tried person-specific thresholds but the direction of correlations was reversed. Person-specific cutoffs remove individual differences and the core question here is an individual differences one.

These findings have implications for the measurement of momentary urgency, and potentially for the articulation of other intense and dynamic events in the moment, such as binge drinking, suicidality, and reactivity. 11/n

Our results (summarized in the table below) suggest that the cooccurrence of intense instances of emotion and impulsivity was more strongly associated with trait scores of urgency and impulsivity relative to the traditional emotion-impulsivity covariance approach. 10/n

Janan Mostajabi @jananmost.bsky.social · 14/05/2025
With ecological momentary assessment data from five preregistered samples and one exploratory sample, we proposed, and found support for, an alternative approach to more adequately capture urgency in the moment. 9/n

Would we really want to say that Person A was highly urgent and Person B was not? 8/n

Janan Mostajabi @jananmost.bsky.social · 14/05/2025
In contrast, take Person B, whose reports of emotion and impulsivity are highly variable. Although they often report intense emotion and impulsivity that frequently cooccur, due to the irregularity of scores, they would have a relatively weaker emotion-impulsivity correlation. 7/n

Janan Mostajabi @jananmost.bsky.social · 14/05/2025
Take Person A, whose reports of momentary impulsivity and emotion always hover in the low range near zero. To the extent that they fluctuate together, this person would have a strong covariance of emotion and impulsivity even though their reports never enter the intense range. 6/n

More recent work studying urgency in the moment as the covariation of emotion and impulsivity has largely found small, nonsignificant associations with trait scores of urgency. Why might that be? 4/n

Janan Mostajabi @jananmost.bsky.social · 14/05/2025
Urgency is a facet of impulsivity defined as the tendency to engage in rash action when experiencing strong emotions. Although urgency is defined as a dynamic, if-then process, the bulk of past work has used cross-sectional dispositional measures to study urgency. 3/n

Janan Mostajabi @jananmost.bsky.social · 14/05/2025
Data from 1,186 participants across six independent samples suggested that the cooccurrence of intense instances of momentary emotion and impulsivity may be a better articulation of momentary urgency than the commonly used emotion-impulsivity covariation approach. 2/n

The HiTOP-PRO domains correlated with individual differences in daily outcomes as expected, with overall positive correlations with negative affect and stress, and negative links with positive affect, energy, and sleep quality. Associations with social interaction outcomes were less robust. 10/

We also see the emergence of new factors, like Grandiosity/Dominance, capturing experiences of well-being, domineering, and exhibitionism, and Rarity/Psychosis, marked by psychosis-like and rare experiences. 9/

There are some key departures, mainly for historically understudied constructs like anankastia, eating problems, and grandiosity. We see individual factors for Eating and Sexual Problems, perhaps due to measurement density, raising questions about the utility of representing such narrow factors. 8/

Exploratory factor analysis indicated a nine-factor model, similar to the HiTOP’s current structure, best represented the measure. Check out the outcome of the bass-ackwards technique, visualizing the hierarchical structure of the measure with 1-9 factors. 6/

Janan Mostajabi @jananmost.bsky.social · 30/01/2025
To address this, the HiTOP recently developed a self-report measure, the HiTOP-PRO, for use in research and clinical practice. This is a critical step as it allows researchers to study the full spectrum of psychopathology as represented by the HiTOP with the same measure and in the same sample. 4/

But this literature is not free of limitations... One major issue with research on the dimensional structure of psychopathology is the reliance on disorder-specific questionnaires and clinical interviews based on traditional categorical frameworks, e.g. the DSM and the ICD. 3/

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional nosological system that aims to address these limitations of categorical organization systems. The HiTOP has generated a new wave of research on the quantitative empirical structure of psychopathology over recent years. 2/

Yet, most research on disinhibition has been cross-sectional and few studies have examined how individual differences in disinhibition manifest in interpersonal functioning in daily life. 3/n
