Five Different Personality Traits And Their Influence On Mental Health

Updated October 13, 2024by Regain Editorial Team

In popular culture as well as everyday conversations, personality is a common topic of discussion, study, and reflection.

How would you describe your own personality? Most likely, your answer is shaped by your experiences, feedback from loved ones, and even online personality tests. While some traits remain fairly constant throughout our lives, our personalities can also evolve and grow over time.

If you’re curious about the different personality traits and how psychologists study and define personality, read on. We’ll review the definitions of personality, five major personality traits, and how therapy can help you understand the link between your personality, mental health, and relationships.

What is personality? 

According to the American Psychological Association (APA), personality refers to the enduring characteristics and behaviors that comprise a person’s unique approach to life. Under this definition, personality includes your major traits, interests, drives, values, self-concept, abilities, and emotional tendencies. 

Personality traits are generally defined by three criteria: consistency, stability, and individual differences. Therefore, a person’s personality traits – like orderliness, creativity, or loyalty, for example – are usually consistent and stable over time, with room for growth and flexibility depending on the situation. 

Across individuals, people vary widely in their behaviors related to a specific trait. This is one of the many reasons why researchers are continually fascinated by personality, and the ways we connect with people whose traits differ dramatically from our own. 

Can personality traits change?

While many personality traits are relatively stable throughout your lifetime, people still have the capacity to change and grow. Importantly, personality traits reflect continuous distributions, meaning that each individual can be “low”, medium, or high on any given trait.

Different environmental, sociocultural, and biological factors can all lead to personality change, and some research suggests that people aged 70 and older can still experience significant changes in personality. Other studies note a relationship between seeing a therapist and lower levels of neuroticism over time. 

The key takeaway? While many of our personality traits are consistent throughout our lives, some aspects of personality can change gradually over time, and often for the better. These shifts may stem from major life events like divorce, a career change, or the death of a loved one, as well as committing to personal change through therapy and goal setting.

What are the five different personality traits? 

In the field of personality psychology, many researchers use the “Big Five” personality model as a guiding framework. The Big Five personality traits are:

  1. Openness to experience
  2. Conscientiousness
  3. Extraversion
  4. Agreeableness
  5. Neuroticism

Although these are not the only personality traits in the human population, they provide a helpful way to frame some of our most common characteristics. We’ll examine the key traits in each of the Big Five dimensions, as well as the influence of personality on your friendships, family bonds, and love life.

1. Openness to experience

Openness describes a person’s tendency to be open to new experiences and generally appreciate novelty. When reflecting on how “open” you are to newness, think about your past responses to new art, ideas, values, feelings, experiences, or behaviors. 

Within all Big Five traits, there are certain “facets” or more specific, lower-level units of personality. Under the category of openness, these facets include:

  • Being prone to fantasy
  • Displaying openness to feelings and diverse behaviors
  • Considering various values, beliefs, and ideas

Considering these facets, someone who is highly open tends to enjoy the arts and creativity, and actively seeks out unfamiliar places and people.

2. Conscientiousness

A conscientious person tends to be careful, timely, hardworking, and adhere to the rules. Facets of conscientiousness include:

  • Orderliness
  • Competence
  • An orientation toward achievement
  • Self-discipline 
  • Deliberate, dutiful behavior

On the Big Five test, people who score highly in conscientiousness tend to study hard, complete their work thoroughly and on-time, and maintain routines and healthy behaviors related to diet, exercise, and public health measures like wearing a bicycle helmet.

3. Extraversion

You’re likely familiar with the common distinction between extraverts – typically, more outgoing and sociable people – compared to quieter, more reserved introverts. The dimension of extraversion captures this spectrum of sociability, with the caveat that a person’s “sociability” can shift depending on their environment, mood, and other circumstances.

People who score higher in extraversion typically exhibit the following facets of personality: 

  • A sociable, active presence
  • A warm, generally positive emotional state
  • A desire for excitement 
  • Assertiveness

Like other personality traits, extraversion encompasses a spectrum of behaviors and may be influenced by situational factors, like the comforting presence of an old friend or family; or, conversely, an intimidating audience or disagreeable coworker.

4. Agreeableness

As you might expect, a more agreeable person tends to agree and go along with others’ demands and actions, rather than assert their own opinions and choices. Core facets of this personality trait include:

  • Sense of trust
  • Modesty
  • Altruism
  • A straightforward mindset
  • Tenderness

In certain situations, agreeableness can cultivate forgiveness and a helpful, communal environment. But if you’re too agreeable, you may limit opportunities for respectful debate or notice that others take advantage of your kindness. Like many personality traits, finding the right balance of assertiveness and a kind, good-natured spirit is key.

5. Neuroticism

Neuroticism describes a person’s interpersonal sensitivity and their tendency to experience “negative” emotions such as anger, worry, and sadness. These emotions are universal and not necessarily negative, but they can be intense and upsetting to experience. Ideally, taking time to process these emotions can improve a person’s understanding of themselves, other people, and the world at large. 

A more neurotic person may struggle to process these emotions in a healthy way. Additionally, they may worry frequently about little things, avoid risks, and generally feel insecure and inadequate. Other facets of neuroticism include:

  • Anxiety, anger, and depression
  • Self-consciousness
  • Impulsivity
  • Vulnerability

Again, most people experience these emotions and behaviors from time to time; but among those who score higher in neuroticism on the Big Five test, these facets are more consistent and may prevent them from pursuing new adventures or challenges.

Building on the big five: Other personality traits

While the Big Five personality framework is widely used and accepted in the psychological community, researchers have identified other personality traits that may improve our understanding of personality across cultures

Most notably, some researchers point toward a sixth dimension of “Honesty-Humility”. People with high levels of honesty and humility are typically sincere, fair, and modest, while lower levels of these traits correspond with manipulative, narcissistic, and self-centered behaviors. 

Other studies suggest the existence of personality traits unique to China, Denmark, Bolivia, the Philippines, and other cultures, which are not captured by the Big Five. If anything, this research illuminates the complexity of personality and the value of psychological research to enhance our self-understanding.

Learn more about personality in online therapy

Learning about personality is fun but complicated – which is why more people are seeking therapy to understand their traits and connect more authentically with friends and loved ones. 

While some people prefer in-person therapy, a growing number of individuals and couples use online therapy to support their personal growth. Using a digital platform like Regain, you can connect with a licensed therapist shortly after completing a brief questionnaire. Each Regain therapist has at least three years of professional experience, plus expertise in relationship therapy and extensive knowledge of human personality and behavior.

Several studies show the value of online therapy to improve self-understanding and mental health, including a 2016 review of the effectiveness of online mindfulness-based interventions (MBIs). Based on results taken during 15 randomized controlled trials, the researchers found that online MBIs have significant small to moderate effects on mental health. The studies noted significant reductions in anxiety, stress, and depression, as well as improvements in well-being and mindfulness. More studies are needed to assess the value of online therapy for concerns related to personality, but current research shows that online therapy can effectively address a range of psychological concerns.

Takeaway

Wherever you fall on the spectrum of personality, your unique traits and behaviors form the basis of your identity, relationships, and the way you learn and interact with the world.

We’re always learning and evolving, both individually and in our relationships. This is an exciting process, but the journey can also be overwhelming and tough to navigate on your own. If you’re looking for guidance as well as expertise, a licensed therapist is ready to support you and help you uncover the most honest and confident version of yourself.
