Locating triarchic model constructs in the hierarchical structure of a comprehensive trait-based psychopathy measure: Implications for research and clinical assessment.

The triarchic model posits that distinct trait constructs of boldness, meanness, and disinhibition underlie psychopathy. The triarchic model traits are conceptualized as biobehavioral dimensions that can be assessed using different sets of indicators from alternative measurement modalities; as such, the triarchic model would hypothesize that these traits are not confined to any one item set. The present study tested whether the triarchic model dimensions would emerge from a hierarchical-structural analysis of the facet scales of the Elemental Psychopathy Assessment (EPA), an inventory designed to comprehensively index psychopathy according to the five-factor personality model. Study participants (Ns = 811, 170) completed the EPA and three different scale sets assessing the triarchic traits along with criterion measures of antisocial/externalizing behaviors. Bass-ackwards modeling of the EPA facet scales revealed a four-level structure, with factors at the third level appearing similar to the triarchic trait dimensions. An analysis in which scores for the Level-3 EPA factors were regressed onto corresponding latent-trait dimensions defined using the different triarchic scale sets revealed extremely high convergence (ßs = .84-.91). The Level-3 EPA factors also evidenced validity in relation to relevant criteria, approximating and sometimes exceeding that evident for the Level-4 EPA factors. Together, these results indicate that the triarchic trait constructs are embedded in a psychopathy inventory designed to align with a general personality model and effectively predict pertinent external criteria.

Boldness moderates cognitive performance under acute threat: Evidence from a task-switching paradigm involving cueing for shock.

Understanding factors that influence behavioral performance in high-pressure contexts is relevant to critical occupations such as first responders, military personnel, and frontline medical workers. A recent study by Yancey et al. (2019) demonstrated an association between boldness, a biobehavioral trait reflecting social dominance and fearlessness, and enhanced task-switching performance during threat of shock relative to a no-shock (safe) condition. This study used a sustained threat manipulation in which cues signaling possible shock were present throughout blocks of multiple task trials. Here, we extended this work by evaluating the relationship between boldness and task-switching performance under acute threat of shock conditions, in which cues signaling possible shock occurred during individual task trials, intermingled with safe trials. Participants (N = 79) completed a task-switching procedure involving acute threat of shock in which unwarned noise probes were presented to elicit blink-startle responses. Boldness was associated with better switching performance under threat versus safe conditions, with high-bold participants who exhibited low startle potentiation during threat showing the best performance. These findings provide additional evidence that dispositional boldness is a meaningful individual difference characteristic related to effective performance in high-pressure situations and have implications for personnel selection and assignment.
