Positive psychology: a revolution in the understanding of well-being
For most of the 20th century, psychology was almost exclusively a science of suffering: identifying pathologies, understanding dysfunctions, treating disorders. This was not a failure of intention — it was a logical consequence of context (two world wars, a traumatized generation).
In 1998, Martin Seligman, then president of the American Psychological Association, launched what would become positive psychology: the science of well-being, flourishing, and human strengths. The guiding idea: psychology has just as much right to study what goes well as what goes wrong.
VIA character strengths are one of the empirical pillars of this revolution.
The PERMA model
Seligman proposed a 5-dimension model of well-being, known by the acronym PERMA:
P — Positive Emotions
Joy, gratitude, serenity, interest, hope, amusement, pride, awe, love. These emotions are not superficial — they have measurable effects on physical health, creativity, resilience, and longevity.
VIA links: Gratitude, Hope, Humor, Appreciation of Beauty, Zest
E — Engagement
The flow experience — complete absorption in an activity. Csikszentmihalyi showed that engagement is one of the deepest sources of happiness. Signature strengths, used in well-matched activities, are the most direct path to flow.
VIA links: All signature strengths — flow happens when strengths are maximally engaged
R — Relationships
Positive connections with others are one of the most reliable predictors of lasting well-being. Not the quantity of relationships — their quality.
VIA links: Love, Kindness, Social Intelligence, Forgiveness, Gratitude
M — Meaning
Belonging to and serving something larger than oneself. Meaning does not come from happiness — often it is the reverse. People with a strong sense of meaning endure more suffering without collapsing.
VIA links: Spirituality, Perspective, Hope, Fairness, Leadership
A — Accomplishment
Pursuing and achieving goals for their own sake. Achievement matters in itself, not only as a means to other ends.
VIA links: Perseverance, Self-Regulation, Bravery, Creativity
Research on strengths and well-being
Here is an overview of the most significant studies:
Foundational study — Seligman et al., 2005
One of the most-cited studies in positive psychology. Two strength-related interventions:
- "Identify your top 3 strengths and use them in new ways for 1 week": measurable reduction in depressive symptoms after 1 week, with effects persisting at 6 months.
- "Write down 3 good things that happened today, for 1 week": same effects.
Both interventions outperformed the control group (placebo autobiographical writing exercise).
Signature strengths and work engagement
Studies by Gallup and Harter (2002–2015) on millions of employees show that daily use of signature strengths predicts work engagement more reliably than most organizational variables.
Strengths and depression
Forest et al. (2012) showed that using core strengths satisfies fundamental psychological needs (autonomy, competence, relatedness) as defined by Self-Determination Theory. Satisfaction of these needs is a negative predictor of depression.
Strengths and resilience
People who know and use their strengths recover faster from stressful events. Not because they face fewer difficulties — but because they have an inner bank of resources to mobilize.
Strengths-based interventions
1. "Use a signature strength in a new way" (Best Practice)
How: Choose one of your top 5 strengths. For one week, use it in a context where you have never used it before.
Why it works: Novelty amplifies the positive effect of strength use. Habit would attenuate the effect — changing context refreshes it.
2. Strengths journal
How: Each evening, note a situation from the day where you used one of your strengths. Describe the situation, the strength used, and how you felt.
Why it works: Conscious reflection reinforces self-awareness and the capacity to intentionally activate strengths.
3. Strengths-based planning
How: In the morning, read your signature strengths list. Ask yourself: how can I use at least one of these strengths today? Specifically, in which activity?
Why it works: Intentional planning increases the probability of use — what is made conscious is more easily mobilized.
4. Appreciation letter
How: Write a thank-you letter to someone who has had a positive impact on your life — and if possible, read it to them in person.
Why it works: Activates Gratitude, Love, and Kindness simultaneously. Seligman's 2005 study showed an immediate increase in happiness and a persistent effect one week later.
Strengths and depression prevention
Positive psychology research does not claim that character strengths "cure" clinical depression. But there are clear empirical links between strength use and prevention:
Mechanism 1: Satisfying fundamental needs Using strengths satisfies the needs of autonomy, competence, and relatedness (Self-Determination Theory). Chronic frustration of these needs is a depressive risk factor.
Mechanism 2: Increasing positive emotions Positive emotions have a "broaden and build" function (Fredrickson): they expand the repertoire of thoughts and actions, and build lasting resources. This is the opposite of the cognitive narrowing associated with depression.
Mechanism 3: Meaning and engagement Depressed people often report a sense of emptiness and lack of meaning. Intentional use of strengths in meaningful activities directly counteracts this experience.
Important: these benefits apply in a context of everyday well-being and prevention. In the case of clinical depression, professional support is essential.
Flourishing: beyond happiness
The word "happiness" is often misunderstood. Positive psychology does not aim at happiness as simple absence of pain or as a permanent state of positivity. It aims at flourishing — complete human thriving.
Flourishing includes:
- Frequent positive emotions (not permanent)
- Deep engagement in meaningful activities
- Quality relationships
- A sense of accomplishment
- A sense of purpose
Signature strengths are the primary driver of flourishing — not because they eliminate difficulties, but because they provide the resources to navigate them and emerge stronger.
Starting now
No need to wait until you have taken the VIA test, read everything, or found the perfect moment. One single question is enough to begin:
"What is the thing I do where I feel most like myself?"
Do more of it. Deliberately. That is the beginning of everything.
