Defining Mental Health: Six Models Explained

Mental health is one of those terms that gets used loosely but rarely defined with precision. Is it the absence of a diagnosis? The ability to handle stress? The capacity to feel happy? Psychologists and public health experts have grappled with this question for decades, and the result is a rich landscape of definitions. Understanding the major models of mental health matters because each one shapes how we measure well-being, design interventions, and even how we judge ourselves. Here are six influential frameworks that have defined the conversation.

The concept of mental health 🔗

The World Health Organization offers the most widely cited starting point. According to the WHO, health is “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity,” which means mental health is far more than just being free of psychiatric illness. The WHO further describes mental health as a state of well-being that enables people to cope with the stresses of life, realise their abilities, learn well, work well, and contribute to their community.

This definition does heavy lifting. It positions mental health as a positive state with its own characteristics, not simply the leftover space after illness is ruled out. It also recognises that biological, social, and economic factors all shape psychological well-being. A college student in Kolkata juggling exam pressure, family expectations, and an uncertain job market is dealing with mental health, whether or not they ever see a clinician.

Because the WHO framing is broad, scholars have proposed more specific models to pin down what positive mental health actually looks like. The six models below are among the most influential.

Model A: Mental health as above normal 🔗

This perspective treats mental health as a level of functioning that goes beyond what is merely average or symptom-free. The most cited foundation for this view comes from Marie Jahoda, an Austrian-British social psychologist whose 1958 book Current Concepts of Positive Mental Health reframed the entire field. Jahoda argued that the absence of mental illness was simply not a sufficient indicator of mental health, and she proposed concrete criteria for what genuine psychological flourishing looks like.

Jahoda’s six criteria 🔗

Drawing on the work of thinkers like Abraham Maslow, Carl Rogers, and Erik Erikson, Jahoda identified six basic components of positive mental health: attitudes toward the self, growth and self-actualisation, integration, autonomy, accurate perception of reality, and environmental mastery.

Positive attitude toward the self refers to self-acceptance and self-esteem rooted in honest self-knowledge, not blind self-regard. Self-actualisation is the ongoing process of growth and using one’s abilities. Integration captures the balance of psychological forces and resilience to stress. Autonomy means independence from undue social pressure and the capacity for self-regulation. Perception of reality refers to seeing the world without major distortions and with empathy for others. Environmental mastery is the ability to adapt to life situations, succeed in love and work, and solve problems effectively.

Strengths and criticisms 🔗

Jahoda’s framework gave psychology a positive baseline rather than just a checklist of pathologies. The criteria offer clear, observable markers that a clinician or researcher can use to set therapeutic goals. However, the model has faced sustained criticism on two fronts. First, achieving all six criteria simultaneously may be practically impossible for most people, making the ideal feel unreachable. Second, criteria like autonomy reflect the assumptions of individualist Western cultures and may not translate to collectivist societies where interdependence, family duty, and community ties are central to a healthy life. For South Asian contexts, this cultural mismatch is particularly important to keep in mind.

Model B: Mental health as maturity 🔗

The second major model treats mental health as a developmental achievement that unfolds across the lifespan. The clearest articulation comes from Erik Erikson, whose theory of psychosocial development frames healthy personality as the result of successfully navigating a series of life challenges.

Erikson’s eight stages 🔗

Erikson proposed eight stages that a healthy developing individual passes through from infancy to late adulthood, with each stage producing results that influence the stages that follow. Each stage centres on a psychosocial crisis, and resolving it produces a basic virtue that contributes to lifelong well-being.

The stages are trust vs. mistrust in infancy, which yields hope; autonomy vs. shame and doubt in toddlerhood, which yields will; initiative vs. guilt in early childhood, which yields purpose; industry vs. inferiority in middle childhood, which yields competence; identity vs. role confusion in adolescence, which yields fidelity; intimacy vs. isolation in young adulthood, which yields love; generativity vs. stagnation in middle adulthood, which yields care; and integrity vs. despair in late adulthood, which yields wisdom.

How maturity links to mental health 🔗

Mental health professionals frequently use Erikson’s theory to understand clients’ emotional challenges and life transitions, because each stage carries forward unresolved issues into the next. A young adult struggling with intimacy, for example, may be carrying unresolved identity questions from adolescence. Maturity, in this model, is not about age but about the cumulative resolution of these challenges.

The framework is particularly useful for understanding college-age struggles. The identity crisis of late adolescence is not a malfunction; it is the central developmental work of that life stage. If a conflict is not resolved, a person still moves to the next stage but may continue to wrestle with the unresolved issue throughout life. That insight reframes many adult mental health struggles as continued engagement with earlier developmental tasks rather than as failures.

Other influential models of mental health 🔗

Beyond the above-normal and maturity frameworks, four additional models have shaped how researchers and practitioners think about psychological well-being.

Socio-emotional intelligence 🔗

This model defines mental health partly through the capacity to recognise, understand, and manage emotions, both one’s own and others’. Emotional intelligence directly influences mental health by promoting emotional resilience, better stress management, and healthier social relationships, and people with high emotional intelligence are generally more adept at coping with adversity, which makes them less vulnerable to mental health issues like depression, anxiety, and burnout.

The model is especially useful in educational and workplace settings. School-based programmes that teach emotion recognition, empathy, and conflict resolution have shown promise in improving overall psychological functioning. The shift here is important: mental health is not just an internal personality trait but a set of social-emotional skills that can be deliberately cultivated.

Subjective well-being 🔗

The subjective well-being framework, developed most prominently by Ed Diener, defines mental health through a person’s own evaluation of their life. It has three components: life satisfaction (a cognitive judgement that one’s life is going well), the presence of positive emotions, and the relative absence of negative emotions. People’s well-being includes both cognitive aspects like life satisfaction and affective aspects like happiness.

This model places authority squarely with the individual. No outside expert can tell you whether you are mentally healthy in this sense; you are the one who decides if your life feels worthwhile. The approach has been criticised for being too closely tied to happiness and overlooking deeper forms of meaning, but it remains influential, especially in global well-being surveys and policy research.

Positive emotions 🔗

Closely related to subjective well-being, this model focuses on the role of emotions like joy, gratitude, hope, and contentment in mental health. Barbara Fredrickson’s “broaden-and-build” theory suggests that positive emotions widen our thinking and help us build lasting psychological, social, and physical resources. Frequent positive emotional experiences are not just pleasant; they are linked to better cognitive flexibility, stronger relationships, and improved resilience over time. This perspective has shaped much of the positive psychology movement and informs interventions like gratitude journalling and savouring exercises.

Resilience 🔗

The resilience model defines mental health through the capacity to recover from, adapt to, and grow from adversity. Rather than focusing on the steady state of well-being, it asks how people bounce back from setbacks, trauma, and chronic stress. Research shows that emotional intelligence is positively correlated with life satisfaction and psychological resilience, suggesting that resilience sits at the intersection of multiple mental health frameworks.

For populations facing significant adversity, whether students dealing with academic pressure, families navigating economic stress, or communities recovering from disasters, the resilience lens is especially valuable. It treats mental health as dynamic, something built through coping skills, social support, and meaning-making, not as a static personal quality you either have or lack.

Why multiple models matter 🔗

Each of these six models captures a real and important dimension of mental health, but none is complete on its own. Jahoda’s framework gives us a positive ideal but risks being culturally narrow. Erikson’s stages explain lifespan development but say less about day-to-day flourishing. Emotional intelligence is teachable but does not guarantee well-being. Subjective well-being respects individual judgement but can downplay structural inequality. Positive emotions are valuable but cannot mask serious distress indefinitely. Resilience is essential but should not become an excuse for ignoring the conditions that create adversity in the first place.

A useful working understanding of mental health draws on all six. It recognises that well-being involves positive functioning, developmental growth, emotional skill, subjective satisfaction, positive affect, and the capacity to adapt. It also acknowledges that mental health exists on a continuum, is shaped by context, and shifts across the lifespan rather than remaining fixed. For students of public health, this multi-model view is more than academic; it shapes how communities design schools, workplaces, and clinical services that actually support flourishing.

What do you think? Which of these six models most closely matches how you personally judge whether someone, including yourself, is mentally healthy? And do you think frameworks developed largely in Western contexts need significant adaptation to fit South Asian cultural realities around family, autonomy, and community?
