How the Big Five Personality Traits Shape Who Seeks Therapy and Who Benefits Most

If you have ever wondered whether your personality plays a role in how likely you are to pick up the phone and book a therapy appointment, the answer is yes. It does. And more importantly, your personality also shapes how much you get out of therapy once you are there.

For decades, researchers have been digging into the connection between personality type and therapy. I chose to explore this through the lens of the Big Five, one of the most trusted frameworks in personality science. The Big Five measures five core dimensions of who you are: Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism. Each one has a spectrum, meaning you can score high, average or low on each trait, and where you fall on the spectrum can say a lot about how you relate to therapy.

So which types are most likely to walk through a therapist's door? And once they do, who tends to benefit the most? Let’s look at the evidence.

The People Most Likely to Seek Help

If you had to guess which trait would top the list of the people most likely to seek a therapist’s help, you would probably pick Neuroticism. People on the higher end of the Neuroticism spectrum operate on “high alert.” They worry and overthink, especially in stressful conditions, and they experience negative emotions more deeply. Anxiety, sadness, irritability. They tend to sit with those feelings longer and ruminate more.

This is precisely why you would expect them to be the first to seek therapy. 

However, research challenges this assumption. One 2025 study surveyed 294 Filipino adults using the Big Five personality assessment and found that higher Neuroticism was actually associated with greater hesitancy toward seeking professional support. The reason, the researchers said, is something called “stigma sensitivity.” According to their findings, people carrying the heaviest emotional weight were also the most afraid of what seeking help might say about them.

On the other hand, people higher in Conscientiousness and Extraversion were more likely to be willing to seek professional support. Conscientious individuals turn to therapy because they are proactive about their well-being. They set goals, follow through on plans, and treat therapy like any other form of self-improvement. Extraverts, meanwhile, are often more comfortable opening up in social settings, and often talk out loud to process their thoughts and feelings. The vulnerability of a therapy session feels less daunting to them as a result.

Openness also plays a role in therapy-seeking. People high in Openness are imaginative, curious, reflective, and drawn to exploring new ideas and inner experiences. They tend to be more receptive to the concept of therapy itself. 

Çekici (2019) found that Openness, along with Extraversion and Conscientiousness, had positive indirect effects on help-seeking attitudes, with cognitive flexibility serving as a key mediator. Essentially what this means is that trait Openness doesn’t make people more pro‑therapy directly; instead, it’s linked to greater willingness to seek help because it’s associated with being more mentally flexible. Or even more simply, people who think more flexibly about their problems are more willing to seek professional guidance for them.

Once You Are in the Therapy Room, Who Benefits Most?

Getting to therapy is one thing. Getting something meaningful out of it is another. And this is where personality research gets intriguing.

A 2019 meta-analysis of 99 studies with a combined sample of more than 107,000 participants showed that personality traits are systematically related to therapy outcomes. Generally, lower levels of Neuroticism and higher levels of the four other traits were associated with greater benefits from therapy.

Let's break that down trait by trait.

Agreeableness 

Agreeableness stood out for its positive association with the “therapeutic alliance,” which measures the quality of the relationship between a client and their therapist. This makes sense when you consider that Agreeable people tend to be trusting, accepting, cooperative and empathetic. They are often willing to collaborate with their therapist rather than resist the process. A strong therapeutic alliance is one of the most reliable predictors of good outcomes in therapy, regardless of the specific approach being used.

Conscientiousness

Conscientiousness leads to better therapy outcomes because people who score higher in this trait are much more likely to follow-through and, notably, abstain from substances. Conscientiousness is the trait of hard work, persistence and reliability; those who score highly bring discipline and structure to their therapeutic work. They are more likely to complete homework assignments, show up consistently, and apply what they learn between sessions.

Extraversion

According to the research, Extraversion was associated with symptom reduction, especially in outpatient settings. For example, Extraverts were more willing to participate and communicate openly during therapy sessions, and especially group sessions.

Interestingly, the relationship flipped in inpatient settings, where lower Extraversion (Introversion) was actually linked to better outcomes. This suggests that the social demands of group-based programs may not suit everyone equally, and finding a therapeutic approach that suits your natural social rhythm can make a meaningful difference to how much you actually benefit from treatment.

Openness to Experience

Trait Openness was found to be connected to greater responsiveness to therapeutic interventions. People high in Openness tend to be more willing to explore uncomfortable emotions, consider alternative perspectives, and engage with the creative or introspective elements of therapy. As a result, they may find it easier to lean into the process and translate insight into meaningful change.

The Neuroticism Paradox

Then there is Neuroticism, which presents something of a paradox. High Neuroticism is the trait most strongly associated with the distress that drives people to seek therapy in the first place. But it also tends to predict less favorable treatment outcomes, at least in the short term.

Hengartner and colleagues (2020) tracked 47 patients through six months of outpatient psychotherapy in a prospective observational study. Researchers found that higher baseline Neuroticism predicted less symptom reduction over the course of treatment. However, their Neuroticism scores decreased significantly during therapy, alongside increases in Extraversion and Openness. This aligns with a broader body of research suggesting that therapy can shift personality traits over time, even if those shifts are modest.

In another study, Nguyen and colleagues (2020) tracked clients over time at a community mental health clinic and found the same thing. As clients became less Neurotic during therapy, their symptoms improved in step. Put simply, therapy was not working despite their Neuroticism; it was working on their Neuroticism, and that was what made them feel better.

What This Means for You If You Are Seeking Therapy

If you score high in Neuroticism and feel you might benefit from therapy, you could be right. Therapy could be one of the most impactful things you can do for yourself. 

Certain approaches seem to work especially well for people who score high in this trait. That includes Cognitive Behavioral Therapy which helps you catch and reframe the negative thought spirals that keep you stuck, and Acceptance and Commitment Therapy which might help you build a different relationship with difficult emotions. Everyone experiences high Neuroticism a little differently, however, so it can be worth experimenting with different therapeutic approaches and practitioners until you find the one that fits how you process and cope best.

If you are naturally Conscientious, you probably already treat therapy like a project you are committed to. Lean into that strength. Your follow-through is one of your biggest assets in the therapeutic process.

If you are high in Openness, you may thrive in insight-oriented or experiential therapies that give you space to explore your inner world. Your willingness to sit with complexity and ambiguity is a gift in the therapy room.

If you are Introverted or lower in Agreeableness, the fit between you and your therapist becomes especially important. The right match in communication style and approach can be the thing that turns therapy from something you endure into something that is actually meaningful.

The Bigger Picture

One final thing to understand is that the relationship between your personality traits and therapy is not a static one, and therapy could subtly change your personality expression over time. 

When Roberts and colleagues (2017) reviewed 207 studies, they found that people who went through therapy became measurably more Extraverted and emotionally stable over time. Emotional stability is related to lower levels of Neuroticism, and is also one of the five facets of emotional intelligence. It’s the trait that helps you stay calm under pressure and respond to situations in an appropriate way.  These findings suggest that therapy does not just help you manage what you are feeling right now, but could also gradually influence the patterns of thinking and reacting that shape how you experience the world.

Also, bear in mind that while your personality influences how you enter therapy and what the process feels like, it does not cap how far you can go. What matters most is your willingness to engage in therapy, no matter what your starting point looks like.

If you are contemplating therapy, taking a Big Five personality assessment can give you a clearer starting point for thinking about what you might want or need from the process. And if you are not, it is still a useful lens for understanding how you move through the world.
