A comprehensive new study led by researchers at the University of Toronto has provided a transformative look at the psychological experience of emptiness, challenging long-held clinical assumptions about how this profound "inner void" functions within the human psyche. Published in the journal Personality Disorders: Theory, Research, and Treatment, the investigation utilizes modern smartphone-based tracking to demonstrate that emptiness is not merely a static symptom of specific personality disorders, but a dynamic and fluctuating state that correlates deeply with identity formation, emotional regulation, and even interpersonal empathy.
For decades, the sensation of feeling "empty" has been one of the most elusive and distressing complaints brought to mental health professionals. Despite its prevalence in clinical settings, the psychiatric community has historically struggled to define it. The current Diagnostic and Statistical Manual of Mental Disorders (DSM-5) primarily recognizes chronic feelings of emptiness as a diagnostic criterion for Borderline Personality Disorder (BPD). Furthermore, the manual characterizes it as a "chronic" condition—a persistent, unchanging trait. This new research, however, suggests that emptiness behaves more like a "state" than a "trait," ebbing and flowing in response to daily life events and social interactions.
The Evolution of the "Inner Void" in Psychological Theory
To understand the significance of the Toronto study, it is necessary to examine the historical context of emptiness in psychological literature. Early psychoanalytic theorists, such as Melanie Klein and Otto Kernberg, often described emptiness as a defense mechanism or a result of "internal object loss"—a sense that the internal world is barren because the individual cannot maintain a stable mental representation of supportive others.
In the mid-20th century, emptiness became a hallmark of the "existential vacuum," a term coined by Viktor Frankl to describe a lack of meaning in life. However, modern clinical psychology began to narrow its focus, eventually tethering emptiness almost exclusively to BPD. This categorization has long been criticized by clinicians who observe emptiness in patients suffering from major depressive disorder, narcissistic personality disorder, and various trauma-related conditions.
The University of Toronto team, led by psychology researcher Amanda A. Uliaszek along with colleagues Amanda Magurno, Saleena Zedan, and Marc A. Fournier, sought to move beyond these categorical constraints. They framed their study within the context of the "dimensional model" of personality, which views mental health through the lens of functional impairments in the self and interpersonal relations, rather than strictly through checklists of symptoms.
Methodology: The Power of Experience Sampling
The research team employed a sophisticated methodology known as experience sampling (ESM), or ecological momentary assessment. This approach is designed to overcome the "recall bias" inherent in traditional psychological surveys, where participants are asked to remember how they felt over the previous weeks or months. By using smartphones to capture data in real-time, the researchers were able to create a high-resolution map of the participants’ internal lives.
The study recruited a community sample of 120 adults, eventually focusing on 113 individuals after accounting for technical data exclusions. The process began with a comprehensive baseline assessment. Participants completed standardized questionnaires measuring their general personality functioning, their ability to regulate emotions, and their underlying levels of identity disturbance.
Following the baseline, the two-week tracking phase commenced. For 14 consecutive days, participants received four random alerts daily on their smartphones. At each "ping," they were required to rate the intensity of four specific affective states—sadness, anger, fear, and emptiness—experienced within the previous hour. This resulted in thousands of data points, allowing the researchers to distinguish between "trait emptiness" (a person’s average level) and "state emptiness" (how much they deviated from their own average at any given moment).
Chronic Emptiness and the Crisis of Identity
The results of the study revealed a powerful correlation between high average levels of emptiness and disturbances in identity. In the modern framework of personality functioning, identity is defined by the ability to maintain a consistent sense of self, possess a range of emotional experiences, and maintain self-esteem.
The researchers found that individuals who reported a frequent and intense "inner void" often felt as though they were "not real" or lacked a fundamental "soul." This specific deficit in selfhood was the strongest predictor of chronic emptiness. Interestingly, the study distinguished between identity and "self-direction"—the ability to set and pursue meaningful goals. While one might assume that aimlessness leads to feeling empty, the data showed that a lack of self-direction did not necessarily predict emptiness. This suggests that the void is not about "what one does," but rather "who one is."
When a person lacks a consolidated identity, their internal world becomes fragile. Without a firm "anchor" of self, the individual may feel hollow, as if they are merely a shell reacting to the environment rather than a person acting upon it. This finding aligns with the "Alternative Model for Personality Disorders" (AMPD) in the DSM-5, which emphasizes that identity impairment is a core feature of personality dysfunction.
The Volatility of Emptiness and Interpersonal Challenges
While chronic emptiness was linked to identity, the variability of emptiness—how much it spiked and dipped—revealed a different set of challenges. The study found that individuals with highly unstable feelings of emptiness often struggled with intimacy and interpersonal relationships.
This instability appears to be rooted in a reliance on external validation. When an individual lacks an internal sense of self, they often "mirror" the people around them to feel grounded. Consequently, when they are alone or in a fluctuating social environment, their sense of internal stability collapses, leading to a sudden surge in the feeling of emptiness. This "socially contingent" emptiness suggests that for many, the void is a symptom of a disconnected social life or an inability to maintain close, stable bonds.
Furthermore, the research linked fluctuating emptiness to poor emotion regulation. Participants who could not accurately identify their emotions or who lacked strategies to soothe themselves were more likely to experience volatile swings in emptiness. The study suggests that for these individuals, the "void" may serve as a psychological "shutdown" or a form of emotional numbness that occurs when they are overwhelmed by negative feelings they cannot process.
The Sadness-Void Connection and the Empathy Paradox
One of the most significant data points emerged from the comparison of emptiness with other negative emotions. The researchers found that sadness, more than anger or fear, was the primary "companion" to emptiness.
On days when participants felt more sad than usual, they almost invariably felt more empty. Moreover, a person’s baseline level of sadness was the only emotional metric that could predict their baseline level of emptiness. This explains why emptiness is so frequently reported in cases of clinical depression. However, the researchers noted that while sadness and emptiness are linked, they are not identical. Sadness is often a reaction to a loss, whereas emptiness is the sensation of "nothingness" where a self should be.
Perhaps the most surprising finding of the study was the relationship between emptiness and empathy. Contrary to the stereotype that personality dysfunction leads to self-centeredness, the data showed that individuals with higher average levels of emptiness often scored higher on measures of empathy.
The authors hypothesize that people who experience a profound inner void may be more attuned to the suffering of others because they are intimately familiar with emotional pain. This "empathy paradox" suggests that the feeling of being empty does not necessarily mean a lack of feeling for others; rather, it may involve a hyper-sensitivity to the external world as a way to compensate for the internal silence.
Implications for Clinical Practice and Future Research
The findings of the Uliaszek team have significant implications for the future of psychiatric diagnosis and treatment. By demonstrating that emptiness is a transdiagnostic experience that exists on a spectrum, the study advocates for a more nuanced approach to mental health.
- Beyond BPD: Clinicians should be wary of assuming that a complaint of emptiness automatically points to Borderline Personality Disorder. Because emptiness is tied to identity and sadness, it should be evaluated as a broader indicator of personality health and mood stability.
- Targeting Identity in Therapy: Since identity disturbance was the primary driver of chronic emptiness, therapeutic interventions like Dialectical Behavior Therapy (DBT) and Schema Therapy should place a heavy emphasis on "self-building." Helping patients develop a coherent narrative of who they are may be more effective in filling the void than simply treating the symptoms of depression.
- The Importance of Real-Time Monitoring: The success of the experience sampling method suggests that smartphone-based tracking could become a valuable tool in clinical settings. Allowing patients to track their "void" in real-time can help therapists identify the specific social or emotional triggers that cause the feeling to fluctuate.
Despite its strengths, the study acknowledged certain limitations. The use of a community sample means that the participants generally had lower levels of distress than a clinical population. Additionally, the researchers used a single-item question to measure emptiness. Future studies may benefit from more complex scales that can differentiate between "emotional emptiness," "existential emptiness," and "social emptiness."
Conclusion: Reframing the Experience of Nothingness
The research titled "Emptiness, Personality Dysfunction, and Emotion Dysregulation: An Experience Sampling Study" represents a pivotal step in demystifying one of humanity’s most uncomfortable sensations. By shifting the focus from a static symptom to a dynamic psychological state, Uliaszek and her colleagues have provided a clearer roadmap for understanding how the inner void interacts with our sense of self and our connections to others.
The study ultimately suggests that emptiness is not an absence of psychology, but a complex psychological event in its own right. It is a signal—a "red flag" from the psyche—indicating that the individual’s sense of identity is undernourished or that their emotional regulatory systems are overtaxed. As the field of psychology continues to move toward dimensional and personalized models of care, this research provides the empirical foundation needed to treat the person, not just the diagnosis, and to help those feeling "nothing" find a way back to "something."
