The goal of this study was to situate subjective emptiness within a diverse and relatively comprehensive array of personality variables to provide context for how this transdiagnostic symptom relates to individual differences in personality and psychopathology. There were five main findings. First, as predicted, subjective emptiness is most strongly related to traits associated with the internalizing spectrum of psychopathology. Second, greater discriminant validity was observed for normal-range as opposed to maladaptive traits. Third, subjective emptiness had different patterns of correlation with normal range aspects, highlighting the value of examining personality constructs that are narrower than broad domains. Fourth, as predicted, subjective emptiness is associated with significant interpersonal distress. Finally, people who report emptiness tend to be cold and submissive both in terms of their interpersonal problems and values. These results add considerable specificity to previous research on the correlates of subjective emptiness.
This study also offers a new perspective on how to think about the experience of emptiness. Most previous research has subjective emptiness as a symptom of a single disorder. However, many people who do not meet citeria for borderline personality disorder are likely to experience clinically significant emptiness. In general, such people will tend to be those who also experience other internalizing symptoms, such as negative affects and social withdrawal. They are likely to be lethargic, lacking drive, enthusiasm, and intellectual curiosity. Results from this study suggest that they may also tend to be somewhat surly and perhaps at times volatile, although correlations with disagreeable traits were somewhat stronger here than in previous studies.
Nuance was also achieved by examining different levels of personality, both in the sense that we examined both broad and narrow features but also in that we examined normal and maladaptive traits, problems, and values. We found greater discriminant validity in normal-range traits than maladaptive traits. This is likely because maladaptive traits are, themselves, more correlated with one another than normal range traits, likely because they share variance related to non-specific distress and dysfunction. We also observed that complexity is masked at the level of broad domains, as subjective emptiness was more strongly related to one aspect of personality than the other for all but one of the big five traits domains. Finally, whereas subjective emptiness was strongly related to the elevation parameter of the interpersonal problems circumplex, indicating that people who feel empty experience relatively more interpersonal distress, the values elevation was relatively modest, indicating that there is not a strong tendency for people who tend to feel empty to have strong feelings about how social interactions should go.
This study may have some implications for the diagnosis of subjective emptiness. It is well known that lower-order features of psychopathology, such as subjective emptiness, have an uncertain location within multidimensional models of psychopathology (Girard et al., 2017; Kim & Eaton, 2015). This work, in conjunction with previous findings, suggests that subjective emptiness could be considered a symptom or feature within the internalizing domain, and in particular, the region of that domain that focusses on distress (Watson et al., 2022). Pending future research, these findings also have some implications for clinical assessment, as patients with the personality profile depicted in this study may be at risk for subjective states, which are known to be associated with serious clinical outcomes such as suicidality. This work also adds to the growing literature supporting the SES as a standalone measure of emptiness.
However, this study was limited by the use of a cross-sectional survey in a convenience sample in the US. Future work that samples individuals from diverse regions of the world, with varying levels of clinical problems, who vary in demographic features such as age, education, and ethnicity is needed to test the generalizability of these results. Multimethod research would be helpful for better understanding the specificity of these findings and the processes by which people who feel empty produce test scores. Likewise, longitudinal or experimental methods should be used to examine causal connections between personality traits and states and the experience of subjective emptiness. Thus far, there is relatively little empirical work on the effective treatment of emptiness as a standalone clinical experience. Given the severe distress and risks associated with emptiness, this is an important area for future research. The development of the SES for the assessment of subjective emptiness and initial validation studies, including this one, provide a strong foundation for future studies on the correlates, causes, prevention, and treatment of subjective emptiness.
