It's one of the five big traits psychology uses to describe personality, and yet it remains the least known outside academic circles. Someone who scores high on this trait doesn't necessarily have a disorder: they simply have a lower threshold for experiencing negative emotions, and a nervous system that activates more easily and more intensely in the face of what it perceives as a threat — real or imagined.
What Neuroticism Is in the Big Five Model
Neuroticism (in Italian, nevroticità) is one of the five traits of the “Big Five” model — along with openness, conscientiousness, extraversion, and agreeableness — formalized by Costa and McCrae with the NEO-PI-R questionnaire (1992), and today the most robust and widely replicated framework for describing individual differences in personality. It measures the general tendency to experience negative emotions — anxiety, sadness, irritability, guilt, vulnerability — and how easily emotional balance is disrupted by stress.
It is not a category (you either have it or you don’t), but a continuous dimension along which each person falls at a different point: someone with a low score tends to remain stable and calm even under pressure, while someone with a high score experiences the same situations with far greater emotional intensity.
How a High Score Shows Up
People with a high level of neuroticism tend to recognize themselves in certain recurring patterns: worry that comes more often and is harder to switch off, a mood that shifts more easily, a stress reaction disproportionate to the objective situation, fairly harsh inner self-criticism, and a tendency to interpret neutral events as threatening. These are often the same people who describe themselves as “too sensitive” or as someone who “makes too big a deal out of things” — a judgment that, it should be said, adds yet another layer of self-criticism to a trait that already brings more emotional suffering on its own.
Neuroticism Is Not a Disorder
It’s important to distinguish the personality trait from the pathology. Having a high score in neuroticism does not mean having an anxiety or mood disorder: it means having one more vulnerability factor. Research has confirmed this for decades — one of the most widely cited meta-analyses on the subject (Ormel et al., 2013) shows that neuroticism is one of the most robust cross-cutting predictors for the development of anxiety and depressive disorders, but the relationship is probabilistic, not deterministic: many people with a high score never develop a clinical disorder, while lifestyle, social support, and coping resources make an enormous difference along the way.
What it depends on
As with other personality traits, neuroticism arises from the interplay between a substantial genetic component (twin studies estimate heritability at around 40-60%) and environmental factors: attachment style in childhood, repeated experiences of emotional invalidation, an unpredictable or overly critical family environment. It is therefore neither a destiny written in the genes nor simply “the character someone builds for themselves” — it is the result of both.
The Consequences When It's Very High
A very high level of neuroticism is often associated with a greater risk of experiencing persistent anxiety — it's worth reading how to understand if you suffer from anxiety to distinguish the personality trait from the disorder itself — and it can also show up physically, through the same mechanisms described in the article on physical symptoms of anxiety. On the relational side, greater emotional reactivity can translate into lower perceived relationship satisfaction and a tendency to interpret conflicts in a more catastrophic way than the situation calls for.
Can It Be Lowered? When It's Worth Seeing a Psychotherapist
The trait itself remains relatively stable over the course of life, but it is not immutable: longitudinal research shows small but real reductions in neuroticism with age and, above all, with targeted therapeutic work — not so much aimed at “changing your personality” as at changing the way you relate to your own emotional reactions. It makes sense to seek professional input when emotional reactivity systematically interferes with relationships, work, or everyday decisions; when self-criticism becomes a constant, wearing inner dialogue; or when you notice yourself avoiding more and more situations out of fear of how you might react emotionally.
How It's Addressed in Psychotherapy
In my work I use an integrated approach with a Gestalt, which helps recognize and move through the emotion as it arises rather than being overwhelmed by it or repressing it, together with cognitive-behavioral tools, useful for identifying the automatic thoughts that amplify emotional reactivity and for building more stable regulation strategies over time.
Frequently Asked Questions
Is Neuroticism the Same Thing as Anxiety?
No. Anxiety is a state (or a disorder, if persistent and impairing); neuroticism is a stable personality trait that makes it more likely to experience anxiety, along with other negative emotions such as sadness and irritability.
Is Having a High Neuroticism Score a Problem?
Not in itself. It is a vulnerability factor that translates into a greater risk of emotional suffering, but it is neither a diagnosis nor a life sentence: many people with a high score lead a balanced life, especially if they have good emotional regulation strategies.
Can Neuroticism Change Over Time?
Yes, although slowly. It tends to decrease slightly with age and can be influenced by targeted psychotherapy work, although it remains one of the most stable personality traits over time.
How Is Neuroticism Measured?
Through validated personality questionnaires such as the NEO-PI-R or shorter Big Five versions; it is not something you can reliably self-diagnose, but a professional can help place it within a broader process of self-knowledge.
I Also Work on This, in Florence
I am Dr. Martina Fino, a psychologist and psychotherapist in Florence registered with the Register of Psychologists of Tuscany. Working on a personality trait like neuroticism isn’t about “becoming a different person,” but about building a more mindful and less exhausting relationship with your own emotional reactions. I see clients at my practice in Florence, in the Campo di Marte-Coverciano area, and I also offer online sessions for those who live outside the city or elsewhere in Tuscany.

In summary
- Neuroticism is one of the five traits of the Big Five model (Costa & McCrae, 1992) and measures the tendency to experience negative emotions more often and more intensely.
- It is not a disorder but a vulnerability factor: it increases the risk of anxiety and depression without automatically causing it.
- It depends both on genetics (estimated heritability of 40-60%) and on environmental factors such as attachment style.
- It remains relatively stable over time, but it can lessen slightly with age and with targeted psychotherapeutic work.
