What Is a Sense of Purpose? A Research-Based Definition

Finishing a goal ends it; a sense of purpose is what hands you the next one. Patrick McKnight and Todd Kashdan, in a 2009 theory that Kashdan’s team refined in 2024, define purpose as a central, self-organizing life aim: one that matters to you, shapes how you spend your time and has no set finish line. They expect most people to have several small purposes rather than one grand calling.¹

In a 2026 meta-analysis of cohort studies from high-income countries, adults who reported more purpose were less likely to die during follow-up, a link that shrank but held after accounting for health habits and depression.² That is a pattern, not proof of cause.

A purpose is an aim with no set finish line

A sense of purpose, in the definition Todd Kashdan and colleagues set out in American Psychologist in 2024, rests on three features. A purpose is central, part of how you see yourself; self-organizing, because it pulls your time, money and attention toward some goals and away from others; and a life aim, a long-term commitment you cannot complete in a short stretch.³

A goal has an endpoint; a purpose need not, so it keeps suggesting the next goal. Kashdan’s team calls purpose a goal manager and gives an example: caring for animals has no end, while becoming a veterinarian, one goal it might produce, finishes with a degree and a job.³

1. 1Purposelive a healthy life: no end point
2. 2Higher-order goalkeep a regular exercise routine
3. 3Subgoala set workout on set days

As an illustration, a team lead whose purpose is helping new people find their feet keeps producing goals nobody assigned her: a guide for new starters, a coffee with each new hire. Goals are where a purpose becomes visible, and the research on how to set goals you will actually reach covers that part.

A quick test follows from the definition. Imagine something you are working toward is done. If nothing follows, it was a goal. If “what next?” answers itself, there is probably a purpose behind it.

Purpose comes in degrees, and most people have several small ones

McKnight and Kashdan’s 2009 theory treats purpose as a matter of degree, not a yes-or-no state. It varies on three dimensions: strength, how much it steers what you do; scope, how many areas of life it reaches; and awareness, how clearly you can see it and put it into words.¹

1. Strength: how much the purpose steers what you do, what you decide and what you give up
2. Scope: how many areas of life it reaches, from one corner of your week to nearly everything
3. Awareness: how clearly you can see it and put it into words; a purpose can work without being named

The dimensions explain why purpose is easy to miss. A purpose can be strong but narrow, such as a community garden plot that fills every weekend, or broad but weak, such as a general wish to be useful that rarely changes a decision. Because awareness is its own dimension, you can act on a purpose you have never named, and the authors expect the average person to have several small purposes, each with a fairly weak pull.¹

Myth

Having a sense of purpose means finding your one true calling.

Fact

Researchers describe purpose in degrees of strength, scope and awareness, and the theorists behind the leading definition expect most people to have several small purposes.

What this means for you: swap “What is my purpose?” for a smaller question, “Where does my effort go when nobody is asking?” The answer often points to a purpose you already have, just a narrow or quiet one.

Does a purpose have to help other people? Researchers disagree

Researchers disagree on whether a purpose must reach beyond yourself. William Damon and colleagues, writing about adolescents in 2003, defined purpose partly to set it apart from personal meaning, which they saw as broader and more inward-looking.⁴

Kashdan and colleagues’ 2024 review quotes Damon’s description of purpose as something of consequence to the world beyond the self, then argues that self-oriented aims count too, since many purposes people describe are personal. The evidence cuts both ways: in one study, adolescents with other-oriented purposes put more effort into related goals and reported greater wellbeing, while in others, adults whose self-oriented purposes felt achievable reported greater wellbeing.³

Both findings fit the idea that a purpose works by organizing effort, whoever it serves. Training for a first half marathon and coaching a children’s sports team can each fill a week with goals. The lesson: do not dismiss an aim because it looks self-centered on paper. Judge it by whether it keeps producing goals, not by how noble it sounds, and if it is a personal aim, keep the next step one you believe you can manage.

Where purpose ends and meaning begins

Meaning in life is the broader idea, and purpose is one part of it. Kashdan’s 2024 review, drawing on work by the psychologists George and Park, describes a meaningful life as some mix of comprehension, a sense that your life makes sense; significance, a sense that it is worth living; and purpose. You can have reliable sources of meaning without a purpose.³

Happiness is different again. A 2013 survey led by Roy Baumeister found that happiness and meaningfulness overlap but have different predictors: getting what you need and want went with happiness, being a giver with meaning, and worry and stress with more meaning but less happiness.⁵ It was a single survey, so it shows patterns, not causes.

The distinction matters when you judge your own aims. A parent up at night with a feverish child is not having a happy night, but hardly a meaningless one; in the survey’s terms, a stretch of life can be high in meaning and low in happiness at once. So ask two questions about an aim: has it felt good lately, and does it still matter to me? Failing the first but passing the second is no sign you picked the wrong aim. If it fails both for weeks and your mood stays low, see the last section.

Is a sense of purpose good for your health?

People with a stronger sense of purpose tend to live longer, according to a 2026 meta-analysis led by Angelina Sutin at Florida State University. The link is consistent but observational, and health habits and depression account for much of it, so it does not show that purpose itself extends life.²

The study

Moderate evidence

Sutin and colleagues' 2026 meta-analysis of purpose and mortality

The researchers pooled published studies with their own new analyses of eight large cohorts. Higher purpose went with a lower risk of dying during follow-up, about a quarter lower in the pooled estimate; the authors’ headline of roughly 30 percent expresses the same result as higher risk for people with less purpose. The review reports relative risks only and does not translate them into numbers of deaths. Allowing for health habits and conditions such as exercise, smoking, high blood pressure, diabetes and obesity shrank the link by more than a third; in the team’s own cohorts, allowing for depression shrank it by about 60 percent. It held in both cases.²

Two things could produce such a link without purpose doing anything: people already becoming ill may report less purpose, and a third factor, such as good health, may raise both purpose and survival. Picture two neighbors of the same age, one who walks daily and one housebound after a stroke: the first may report more purpose and outlive the other without purpose being the reason. In the team’s own cohorts, the link held when deaths in the first year were left out, which weakens the first explanation, but no cohort study can rule out the second. The authors also report a substantial overlap with depression: people with less purpose tend to report more depressive symptoms.²

The finding updates a 2016 meta-analysis of 10 studies that linked purpose to lower risks of death and of cardiovascular events.⁶ In a 2014 analysis of a US national survey that followed adults for 14 years, the link showed no clear difference by age, or between retirees and people still working.⁷

These studies rest on people rating themselves on questionnaires, and the tools are rough. Kashdan’s 2024 review reports that in large population studies, items from Carol Ryff’s 1989 purpose-in-life scale, the most widely used measure, hang together poorly and overlap heavily with other parts of wellbeing, such as self-acceptance.³ The Meaning in Life Questionnaire, published by Michael Steger and colleagues in 2006, measures meaning in life, not purpose on its own.⁸

What this means for you: value purpose for the life it organizes; any health benefit is a possibility the evidence cannot yet promise. A low score on a purpose questionnaire is not a health verdict, and if a lack of purpose comes with low mood, the mood is what to get checked.

Can you build a sense of purpose?

Probably, though the evidence is thinner than the advice about finding your purpose suggests. A 2021 meta-analysis of 33 randomized trials by Nicholas Manco and Sherry Hamby found that several kinds of program raised people’s sense of meaning in life, including some brief ones that did not need a licensed professional. The gains were large against passive comparison groups, much smaller against active ones, and varied widely. In plain terms, a program clearly beats no program and beats another reasonable activity only modestly, and the trials measured meaning rather than purpose alone.⁹

In a large 2022 study of US adults over 50, Julia Nakamura and colleagues found that those who volunteered more, spent more time helping friends, neighbors or relatives, exercised at least weekly and had more social support tended to report more purpose four years later. The links were modest and could partly reflect things the study did not measure, the authors note.¹⁰

Our reading, which these studies suggest but did not test, is that purpose tends to grow out of doing rather than introspection alone. As an illustration, someone starts helping at a children’s sports club because their child joined; three seasons later they run the fixtures and train new coaches. The commitment kept producing goals until it became a purpose.

Caregivers, shift workers and people with illness or tight budgets may have little spare time, and a narrow purpose still counts. If the gap feels biggest at work, weighing whether to change careers is a separate decision with its own evidence.

When a missing sense of purpose needs a professional

Feeling adrift for a while is not in itself a diagnosis. But the UK’s NHS lists feeling hopeless, having no motivation or interest in things and getting no enjoyment out of life among the psychological symptoms of depression, so a lasting loss of purpose deserves a closer look.¹¹ The three levels of urgency below are our arrangement; what each level says comes from the US National Institute of Mental Health (NIMH) or the NHS, except the pointers for other countries, which are our general signposting.

• Now, if you are thinking about suicide or harming yourself, or feel you cannot stay safe: in the US, NIMH lists the 988 Suicide and Crisis Lifeline, where you can call or text 988 or chat online for confidential support around the clock, and says to call 911 or go to the nearest emergency room in a life-threatening situation.¹² In the UK, the NHS says to call 999 or go to A&E if you do not feel you can keep yourself or someone else safe or a life is at risk, and Samaritans take calls free on 116 123.¹³ In England, for urgent mental health help that is not an emergency, the NHS points to NHS 111, online or by phone with its mental health option, or an urgent GP appointment; Scotland, Wales and Northern Ireland have their own services.¹³¹⁴ Anywhere else, call your local emergency number.
• Soon, within days or weeks: the NHS advises seeing a GP if you have symptoms of depression for most of the day, every day, for more than 2 weeks.¹¹ Outside the UK, start with a family doctor or primary care provider.
• Routine: if you feel adrift but not low, NIMH suggests raising mental health concerns at your next primary care appointment; a primary care provider can do an initial screening and refer you to a psychologist, psychiatrist or social worker.¹² If the emptiness comes with exhaustion from your job, reading how the WHO defines burnout can help you put it into words at that appointment.

The bottom line

Look for purpose in whatever keeps handing you the next goal, not in a job title or a single calling; most people’s purposes are several and small. Its link with longer life is consistent across large studies but observational, and where depression was checked, it accounts for much of the link. The practical step is to notice where your effort already goes, and to keep regular commitments that tie you to other people until one starts producing goals of its own.
