“I really don't think I can do this one.” When that thought arrives before you even begin, it is hard to get started. But if you have managed something similar before, the same task feels a little less daunting. The word for this difference is **self-efficacy**. Here is what it means, what Bandura's theory says, how it differs from self-esteem and confidence, and how to build it in everyday life.

What is self-efficacy? Bandura's definition #

Self-efficacy is a concept that American psychologist Albert Bandura set out in a 1977 paper in the journal Psychological Review. Put simply, it is how strongly you believe “I can do this.” Bandura proposed that this belief shapes whether you start something, how much effort you put in and how long you keep going in the face of obstacles and unpleasant experiences.

Researchers sometimes separate two kinds. Task-specific self-efficacy is your belief about one particular activity, such as giving a presentation, exercising or studying. General self-efficacy is a broader belief that you can cope with a wide range of stressful or challenging demands.

How is self-efficacy different from self-esteem and confidence? #

The three sound alike and are often used interchangeably, but each asks a different question.

Confidence is a broad everyday word, while self-efficacy is a research concept that pins down your belief about carrying out a specific task. Self-efficacy and self-esteem can also move separately. You might get things done with ease yet still feel you are not much of a person, or you might value yourself and still feel “I can't do this” in front of something new. If your overall sense of worth is what feels shaky, see how to raise your self-esteem.

Bandura's theory: the four sources of self-efficacy #

Bandura described four main sources of information that shape self-efficacy.

1. Mastery experiences (your own accomplishments): things you have actually managed to do. Bandura listed this source first.
2. Vicarious experience: seeing someone like you succeed makes “maybe I can too” feel more possible.
3. Verbal persuasion: someone you trust telling you “you can do this.”
4. Physical and emotional states: when your heart races and your hands shake, your belief depends on whether you read that as “I can't” or as “my body is getting ready.”

Bandura proposed that the more a source rests on direct experience, the more it changes self-efficacy. He also described how sticking with activities that feel threatening but are in fact relatively safe builds self-efficacy through the experience of managing them, while avoidance behavior decreases. That is why a small thing you actually did tends to stay with you longer than encouragement alone.

Signs of high and low self-efficacy #

Bandura (1982) wrote that self-efficacy influences thought patterns, actions and emotional arousal together. The table below is not a way to sort people into types; the same person can move between these depending on the situation.

A meta-analysis of 114 studies with 21,616 participants (Stajkovic & Luthans, 1998) found an average correlation of about .38 between self-efficacy and work performance. A correlation means the two tend to move together; it does not mean that raising self-efficacy alone will raise performance.

How to build self-efficacy: five ways to stack up small successes #

Here is how the four sources translate into everyday practice. The key is not a big resolution but the experience of finishing something sized so you can actually do it.

1. Break tasks down to a doable size: instead of “write the report,” choose a first step that takes 5 to 10 minutes, such as “write the title and three headings.” This is the same principle as breaking activities into small steps in behavioral activation, explained in our behavioral activation guide.
2. Keep a record of what you did: at the end of the day, note what you got done and rate your sense of accomplishment from 0 to 10. Seeing what you did gives you evidence to draw on next time.
3. Look for stories from people like you: someone who started where you are and got there bit by bit is often more encouraging than someone who was good from the start.
4. Give and receive specific feedback: words that name what was done, such as “you did ten minutes more than yesterday,” stay with you longer than “good job.” Try saying it to yourself, too.
5. Read your body's signals differently: when your heart starts racing, breathe out slowly a few times and name it: “My body is getting ready.”

If comparing yourself with others keeps feeding the thought “I can't do this,” it can help to compare yourself with your past self instead. Our guide to working with inferiority feelings walks through that practice.

Self-efficacy scales: the General Self-Efficacy Scale (GSE) #

The best-known measure is the General Self-Efficacy Scale (GSE), a 10-item scale first developed in German by Matthias Jerusalem and Ralf Schwarzer in 1981 and since translated into many languages, including Korean. A study of 1,933 participants in Germany, Poland and South Korea (941 of them in Korea; Luszczynska et al., 2005) found that general self-efficacy measured with this scale related consistently to other psychological variables across countries, suggesting it works as a concept across cultures.

CareOps does not offer a public self-efficacy scale. A related check is the sense of control check (Pearlin Mastery). It is not the same as a self-efficacy scale; its seven items look at how much you feel you can influence what happens in your life. You can take it right away, with no login.

If you want help stacking up small successes #

Self-efficacy grows less from one big moment than from small successes that add up. CareOps Maeumi is an AI counseling app that runs sessions with approaches such as cognitive behavioral therapy (CBT) and behavioral activation, helps you choose a first step sized so you can do it, and picks up what you tried in the next session.
