Positive psychology is the scientific study of what makes life most worth living. Rather than focusing solely on fixing problems or treating mental illness, it emphasises strengths, virtues and positive experiences. Originating with Martin Seligman in the late 1990s, the field investigates happiness, resilience, wellbeing and human flourishing. It looks at positive experiences (like joy and inspiration), positive traits (such as gratitude and compassion) and positive institutions (applying positive principles within organisations). In coaching, positive psychology provides evidence-based tools that help clients identify and use their strengths, cultivate positive emotions and build meaning. Techniques such as gratitude exercises, strengths assessments and the PERMA model (Positive emotions, Engagement, Relationships, Meaning and Accomplishment) foster wellbeing and motivate action. By focusing on what is already working, clients gain confidence and resilience, allowing them to tackle challenges more effectively. Positive psychology does not deny problems; instead, it broadens the perspective to include growth and potential, making it a powerful complement to traditional coaching methods.
