Positive psychology is a branch of psychology that focuses on understanding and promoting factors that contribute to well-being, resilience, and psychological health. Unlike traditional approaches that emphasize diagnosing and treating mental illness, positive psychology seeks to explore the strengths and resources that enable individuals and communities to thrive. This field was pioneered by psychologist Martin Seligman, who emphasized the importance of studying what makes life meaningful and fulfilling.

Positive psychology identifies and examines the factors that lead to positive emotions, such as happiness, gratitude, and hope as well as traits like optimism and kindness. It also investigates practices and mindsets that promote psychological health, such as mindfulness, goal-setting, and self-compassion. For example, practicing gratitude has been shown to improve mood and foster stronger social connections, while cultivating optimism can enhance resilience in the face of adversity.

One key focus of positive psychology is resilience, which refers to an individual’s ability to recover from setbacks and adapt to challenging circumstances. Researchers in this field study how supportive relationships, emotional regulation, and a growth mindset contribute to resilience and overall well-being.

Positive psychology also aims to enhance well-being by promoting activities and interventions that increase life satisfaction. Strategies such as identifying personal strengths, engaging in meaningful activities, and fostering social connections are central to this approach. The study of flourishing – living a life rich in purpose and engagement – is a core aspect of this field.

Positive Subjective Experiences

Positive subjective experiences refer to feelings and emotional states that enhance an individual’s sense of well-being and satisfaction with life. These experiences, such as joy, gratitude, and contentment, play a significant role in shaping behavior and mental processes by increasing one’s resilience, improving social relationships, and enhancing overall mental health.

Gratitude

Gratitude, a key positive subjective experience, involves recognizing and appreciating the positive aspects of life, whether it be specific events, relationships, or general circumstances. Expressing gratitude significantly enhances subjective well-being, which refers to an individual’s overall evaluation of their happiness and life satisfaction. Research shows that regularly practicing gratitude – such as keeping a gratitude journal, expressing thanks to others, or reflecting on things one appreciates – can improve mood, reduce stress, and strengthen social relationships. Gratitude not only boosts positive emotions, like joy and contentment, but also decreases negative emotions, such as envy and resentment, creating a healthier emotional balance. Over time, these effects contribute to greater resilience, enhanced social connections, and increased overall life satisfaction.

Signature Strengths and Virtues

Exercising signature strengths – an individual’s unique qualities or traits – has been linked to higher levels of positive objective experiences, such as happiness, and greater subjective well-being, or satisfaction with life. When people identify and apply their strengths in meaningful ways, such as creativity, kindness, or perseverance, they tend to experience more fulfillment, resilience, and purpose.

Positive psychology researchers, including Martin Seligman and Christopher Peterson, developed a classification of character strengths organized into six broad categories of virtues. These virtues represent core aspects of human excellence that promote thriving and well-being:

Wisdom: This virtue includes strengths like curiosity, creativity, and love of learning, which involve acquiring and applying knowledge in meaningful ways. 
Courage: This involves emotional strengths such as bravery, perseverance, and honesty, which allow individuals to achieve goals despite challenges.
Humanity: Focused on interpersonal strengths, this virtue includes kindness, love, and social intelligence, which enhance connections with others.
Justice: This virtue pertains to strengths like fairness, leadership, and teamwork, which contribute to creating harmonious and equitable communities. 
Temperance: Strengths such as forgiveness, humility, prudence, and self-regulation help individuals manage impulses and maintain balance in life.
Transcendence: These qualities, such as gratitude, hope, and spirituality, provide a sense of meaning, purpose, and connection to something larger than oneself.

Recognizing and exercising signature strengths requires self-awareness. Tools like the VIA (Values in Action) Character Strengths Survey help individuals identify their top strengths. This awareness helps people align their behaviors with their core values, promoting authenticity and satisfaction.

The six virtues were derived from analyzing philosophical and religious traditions across cultures, suggesting they are universally-valued aspects of character. However, how these virtues are prioritized and expressed may vary across cultures.

Post-traumatic Growth

Post-traumatic growth (PTG) refers to the positive psychological changes that can occur following an experience of trauma or significant stress. Unlike post-traumatic stress disorder (PTSD), a term for the lasting, negative effects of trauma, PTG highlights the ways individuals can emerge from adversity with enhanced personal strength, greater appreciation for life, improved relationships, and a stronger sense of purpose or spirituality. This phenomenon highlights the human capacity for resilience and transformation. It demonstrates how adversity can sometimes lead to profound personal growth and a deeper sense of meaning.

Traumatic experiences, such as serious illness, loss, or natural disasters, often challenge deeply-held beliefs and force individuals to confront their vulnerabilities. This process can lead to introspection and personal transformation. For example, someone who survives a life-threatening illness may develop a renewed appreciation for everyday moments or prioritize relationships more deeply than before. Others may discover new opportunities, shift career goals, or adopt healthier coping strategies.

PTG is not about minimizing the pain of trauma but about recognizing that growth and resilience can coexist with distress. Research has identified five key areas where growth is often experienced after a traumatic or stressful ordeal:

  • Personal strengths: Realizing a greater capacity to handle challenges.
  • Relating to others: Developing deeper and more meaningful relationships.
  • New possibilities: Discovering new paths or opportunities in life.
  • Appreciation for life: Gaining a heightened gratitude for everyday experiences.
  • Spiritual or existential change: Strengthening spiritual beliefs or finding new meaning in life.


Factors that contribute to PTG:

  • Social support: Having supportive relationships facilitates reflection and coping, which can lead to growth.
  • Coping strategies: Habits like journaling, meditation, and exercise all foster PTG.
  • Cognitive processing: Reassessing and making sense of trauma is critical for growth. The ability to reframe traumatic events in a meaningful way contributes to PTG.
  • Personality traits: Traits such as optimism, openness to experience, and curiosity can make individuals more likely to experience PTG.


It is important to note that PTG and resilience are not the same thing. Resilience refers to the ability to bounce back to a pre-trauma state of functioning. It is considered a personal attribute. Post-traumatic growth, on the other hand, implies an improvement or personal growth beyond previous functioning. PTG involves profound changes in perspective and values and occurs in individuals who are not necessarily inherently resilient. It requires a lot of time, energy, and work.

Not all individuals experience positive outcomes after trauma. Some may struggle with long-term distress instead. Some researchers argue that PTG might be an adaptive coping mechanism rather than genuine growth, as individuals may imagine personal growth in order to make their trauma feel more manageable.
