Distinct psychopathic traits are linked to the quality of life behind bars

Recent research suggests that specific psychopathic traits affect how inmates experience their time in prison, with characteristics like emotional coldness and recklessness leading to a noticeably poorer quality of life behind bars. The findings indicate that rule-breaking behavior acts as a bridge between reckless personality traits and a negative prison experience, while manipulative traits do not seem to worsen a prisoner’s overall wellbeing. This research was recently published in the Journal of Individual Differences.

Psychopathy is a personality concept often used in forensic and criminal justice fields to describe a set of traits that have massive implications for a person’s behavior and social life. These characteristics are generally grouped into three main categories based on prominent psychological models. The first category includes affective traits, such as emotional coldness, a lack of guilt, and an inability to feel empathy.

The second category involves interpersonal traits, which include self-centeredness, deceitfulness, and a tendency to manipulate others. The final category encompasses behavioral traits, characterized by impulsivity, recklessness, and a strong inclination toward antisocial actions.

Nikola Drndarević, a research associate and doctoral candidate at the Institute of Criminological and Sociological Research in Belgrade, Serbia, noted that public perception of these traits often misses the mark.

“Psychopathy is often confused with criminality or violence,” Drndarević told PsyPost. “When people hear the word, they often think of serial killers or extreme brutality. In reality, most offenders are not psychopaths, and many people with psychopathic traits are never involved in crime at all.”

While psychopathy is often considered a clinical condition, it does not typically involve symptoms like hallucinations or delusions. People with high levels of psychopathic traits often experience a wide range of negative life outcomes in the community. Research links these traits to higher rates of substance abuse, frequent relationship problems, divorce, and risky sexual behavior.

These individuals also face difficulties maintaining steady employment and tend to report poorer overall physical health. In correctional facilities, they represent a highly challenging population. They tend to have higher rates of violent reoffending, frequently break institutional rules, and often fail to engage with standard rehabilitation programs.

“Another misconception is that fearlessness or emotional detachment are somehow advantageous traits,” Drndarević said. “Although they may sometimes appear adaptive, people high in psychopathic traits often experience poorer long-term outcomes, including unstable relationships, addiction problems, unemployment, and repeated contact with the justice system.”

Despite knowing that psychopathic traits are common in prisons, scientists know relatively little about how these individuals actually perceive their own quality of life while incarcerated. Because inmates have severely restricted autonomy, measuring their quality of life requires a specialized approach. Quality of prison life involves an inmate’s personal experiences, daily activities, interactions with guards, and feelings of safety.

A good quality of life in a prison environment reflects decent physical conditions and a fair administrative organization. Improving this sense of wellbeing might serve as a powerful motivator for inmates to participate in treatment. The authors of the new study aimed to explore this overlooked area.

“This study grew out of a larger project examining the quality of prison life in Serbian prisons and the conditions that make prisons safer, more humane, and more rehabilitative,” Drndarević told PsyPost.

He noted that people with elevated psychopathic traits are substantially overrepresented in correctional settings. “They can have a major impact on everyday prison life, for other prisoners, staff, and the institution as a whole,” Drndarević said. “Yet despite decades of research, we still know surprisingly little about how these individuals actually experience prison or how their personality characteristics shape that experience.”

The research team proposed a theoretical model to test whether psychopathic traits negatively affect an inmate’s perceived quality of prison life. They also wanted to see if institutional misconduct acts as a mediating factor. A mediating factor is a variable that helps explain the relationship between two other variables.

“We wanted to move beyond the simple question of whether psychopathic traits are ‘good’ or ‘bad’ for prison adjustment and ask a more practical question: through what mechanisms do these traits influence life inside prison walls?” Drndarević said.

To test these ideas, the researchers collected data from 282 adult inmates housed across five different correctional facilities in Serbia. The sample included both male and female offenders, with men making up about 76 percent of the group. The average age of the participants was roughly 40 years old.

Their educational backgrounds varied, though a majority had only completed high school or elementary school. Most of the inmates had committed violent crimes, and more than half had a history of previous incarcerations. On average, the participants were serving sentences of around ten years, suggesting a sample with a significant rate of repeat offenses.

The scientists used multiple distinct methods to gather their data. Instead of relying on the inmates to rate their own personalities, trained prison treatment staff evaluated each participant’s psychopathic traits. The staff used a specialized 26-item rating scale to measure three specific traits, which included deceitfulness, emotional coldness, and recklessness. Having trained staff complete these evaluations helps reduce the bias that often occurs when people report on their own negative or socially undesirable behaviors.

To measure the quality of prison life, the researchers asked the inmates to complete a comprehensive self-report survey. This survey asked participants to rate their experiences across several distinct areas. These areas included harmony, which covers respect and staff-prisoner relationships, and professionalism, which covers fairness and bureaucratic legitimacy.

The survey also measured their feelings of security, their satisfaction with physical conditions and family contact, and their opportunities for personal development and wellbeing. Finally, the authors gathered data on institutional misconduct by reviewing official prison records. They looked at four specific indicators of rule-breaking and disciplinary action.

These records included the frequency of disciplinary corrections, such as losing the right to receive packages or spend money. They also tracked special security measures, like the confiscation of items or increased supervision. Additionally, the researchers counted the number of times inmates were placed in solitary confinement or subjected to physical restraint by security staff.

When analyzing the data, the researchers found that emotional coldness had a direct negative association with the quality of prison life. Inmates who scored high on this trait tended to perceive their environment much more negatively. They reported strained relationships with the prison staff, reduced feelings of security, and a lower overall sense of personal wellbeing. The statistical models showed that this trait worsened the prison experience regardless of whether the inmate actually broke the rules.

“One important takeaway is that psychopathy is not one thing,” Drndarević noted. “Modern research increasingly views it as a combination of different characteristics, such as emotional coldness, interpersonal manipulation, and recklessness or impulsivity.”

Recklessness also predicted a lower quality of prison life, but it operated in an entirely different way. The researchers found that recklessness was indirectly related to the quality of prison life through its impact on institutional misconduct. This means that impulsive and reckless inmates were much more likely to break prison rules and engage in conflicts with others.

“The most straightforward finding was that reckless and impulsive traits tended to reduce quality of prison life largely through misconduct: more conflicts, more rule violations, and more disciplinary sanctions,” Drndarević said.

These observable bad behaviors resulted in official disciplinary actions, which in turn led the inmates to report a poorer quality of life. Because recklessness involves outward behaviors like rule-breaking and aggression, it may be easier to address through targeted cognitive therapies. Interventions that focus on helping inmates manage their impulsivity and aggression could directly reduce the number of disciplinary infractions they commit.

“What was more interesting was that emotional coldness appeared to operate differently,” Drndarević explained. “Even when it was not accompanied by rule-breaking, it was still associated with poorer experiences of prison life, particularly in relationships with staff and other prisoners and in feelings of safety and wellbeing.”

This emotional detachment might make it difficult for these individuals to adapt to structured social environments. A lack of empathy can severely limit a person’s ability to understand the mental states of others. This inability to form positive relationships likely undermines the harmony and professionalism that usually make prison life more bearable.

“This suggests that some aspects of psychopathy influence prison life not only through behavior, but also through the way people perceive and navigate social environments,” Drndarević said. “The practical implication is that different traits may require different approaches.”

He added that behavioral problems may respond to structured interventions, whereas emotional and interpersonal difficulties are likely to be much harder to change. These affective deficits may require different management strategies altogether.

Interestingly, the interpersonal trait of deceitfulness did not significantly lower the overall quality of prison life. While highly deceitful inmates did report slightly worse relationships with staff, their manipulation did not seem to affect their feelings of safety, material conditions, or personal development.

The researchers suggest that manipulative tendencies might actually help some individuals navigate the prison environment strategically. By managing their surroundings in a calculated way, they might avoid formal punishments and maintain a stable status among their peers. Deceitful behavior does not necessarily involve overt violence or rule-breaking, allowing these individuals to protect their own wellbeing even if they strain institutional trust.

The authors note a few limitations to their research. The sample of inmates was drawn from specific facilities in Serbia, which might not perfectly represent the broader global prison population. A more diverse international sample would help confirm if these patterns hold true in different cultural and legal contexts.

Another limitation is the study’s cross-sectional design, meaning all the data was collected at a single point in time. This type of design makes it impossible to prove a strict cause-and-effect relationship.

“The effects we observed were meaningful, but they should not be interpreted as destiny,” Drndarević cautioned. “Personality traits explained only part of the differences in how people experienced prison life. Institutional culture, staff-prisoner relationships, prison management, and broader social factors remain extremely important.”

While it makes sense that personality traits lead to rule-breaking and a worse quality of life, it is also possible that a harsh prison environment worsens antisocial traits over time. Future research using longitudinal designs, which track the same individuals over several months or years, could help determine the exact direction of these psychological relationships.

“At the same time, in correctional settings even modest improvements can matter,” Drndarević added. “Small reductions in misconduct or small improvements in prison climate can affect the daily lives of hundreds or thousands of prisoners and staff members.”

Despite the limitations, the research provides evidence that psychopathic traits are not all the same when it comes to daily life in a prison environment. By breaking psychopathy down into specific categories, scientists can better understand how emotional coldness, recklessness, and deceitfulness each create unique challenges.

“Our broader research focuses on how individual characteristics interact with institutional environments to shape behavior, wellbeing, and rehabilitation outcomes,” Drndarević said. “We are currently expanding this work to include the perspective of correctional officers and treatment staff, as well as evaluating staff training programs and institutional interventions.”

He noted that his own research continues to examine the diversity hidden behind diagnoses like antisocial personality disorder and psychopathy.

“One of the recurring findings is that these individuals are often far more psychologically heterogeneous than popular stereotypes suggest,” Drndarević concluded. In other words, people diagnosed with these conditions often exhibit a wide variety of different underlying traits and behaviors.
