Self-efficacy: the power of believing in yourself

Do you know that feeling of facing a new task and sensing deep down: “I can do this”? Or, conversely, that quiet hesitation that whispers, “Maybe you’re not good enough after all”? This inner conviction has a name: self-efficacy. It plays a decisive role in how we approach challenges, whether we persevere or give up, and whether we grow or stagnate. The good news: Self-efficacy isn’t an innate trait, but a skill that can be developed. This article explains what research really knows about it—and how you can specifically strengthen it in your everyday life.

What Is Self-Efficacy? A Definition

Self-efficacy refers to a person’s belief that they can accomplish certain tasks or overcome challenges through their own efforts. It is not about general self-confidence or optimism, but rather a very specific expectation: I am capable of achieving this specific goal through my own actions.

The term was coined by Swiss psychologist Albert Bandura, who, in his groundbreaking 1977 essay on Self-Efficacy Theory, first systematically described how these beliefs guide our behavior. Bandura (1977) demonstrated that people with high self-efficacy expectations choose more difficult goals, persist longer in tasks, and view setbacks as surmountable obstacles rather than personal failures.

It is important to note the distinction: self-efficacy is not the same as self-confidence in the general sense. Self-confidence is a broad sense of trust in oneself. Self-efficacy, on the other hand, is domain-specific—someone can have high self-efficacy in cooking and low self-efficacy in public speaking at the same time. This nuance is what makes the concept so valuable for personal development.

Bandura’s Theory: The Origin of a Revolutionary Concept

Albert Bandura developed self-efficacy theory as part of his broader social-cognitive learning theory. His core argument was as simple as it was revolutionary: Human behavior is not driven solely by external stimuli, but is decisively shaped by the cognitive beliefs a person holds about themselves.

Bandura (1977) observed that two types of expectations shape our actions: first, outcome expectations—that is, the assumption that a certain behavior leads to a specific outcome—and second, competence expectations (also called self-efficacy expectations)—that is, the belief that one is capable of performing that behavior in the first place. According to Bandura, the latter is the more decisive of the two.

This insight had a lasting impact on psychology. Suddenly it became clear: it is not enough to know what is good for you. You also have to believe that you can actually do it. For example, someone who knows that regular exercise is healthy but does not believe they can be a disciplined athlete is unlikely to go running consistently.

The Four Sources of Self-Efficacy According to Bandura

In his later work, Bandura (1997) significantly expanded on the theory and described four central sources that fuel beliefs in self-efficacy. Understanding these sources is the first step toward purposefully working on one’s own expectations of competence.

1. Personal experiences of success (Mastery Experiences)

The strongest source of all. When you accomplish something you set out to do—whether big or small—your brain sends a clear signal: I can do this. The more often you have such experiences, the more stable your self-efficacy becomes. That’s why psychologists often recommend breaking large goals down into smaller, achievable steps. Every small victory is real proof of your ability.

2. Vicarious Experiences

When you see someone else master a challenge that you also find difficult, it strengthens your own conviction. If they can do it, maybe I can too. This effect is particularly powerful when you can identify with the person—similar age, similar background, similar starting point. Mentors, role models, or even community members fulfill exactly this function.

3. Verbal Persuasion

Encouragement from outside sources—whether from family, friends, or a therapist—can boost self-efficacy in the short term. However, this source is less stable than your own experiences. What matters is that the encouragement is credible: empty praise fizzles out, whereas concrete, honest recognition has an impact.

4. Physiological and Emotional States

How your body feels influences what you believe you are capable of. A racing heart before a presentation can be interpreted as a sign of weakness or as a sign of energy—depending on your level of self-efficacy. People with high self-efficacy tend to interpret physical tension as helpful activation, not as a threatening warning signal.

Core idea of self-efficacy research "People with a strong conviction in their own effectiveness see difficult tasks as challenges to be mastered rather than threats to be avoided." - Albert Bandura (1997)

Measuring Self-Efficacy: What the Research Says

How can self-efficacy be scientifically measured? In 1995, Ralf Schwarzer and Matthias Jerusalem developed the General Self-Efficacy Scale (GSE), a measurement tool that remains widely used internationally to this day.

Schwarzer and Jerusalem (1995) focused on general self-efficacy expectations—that is, the fundamental belief that one can handle new or difficult situations on one’s own. Their scale consists of ten statements that respondents agree with or disagree with on a four-point scale ranging from “disagree” to “strongly agree.” Typical items include: “When obstacles arise, I find ways to get my way” or “Whatever happens, I’ll manage just fine.”

The research group was able to demonstrate that high scores on this scale are associated with lower levels of depression and anxiety, better physical health, higher job satisfaction, and better coping with stress. In other words: Self-efficacy is not a psychological luxury—it is a key protective factor for mental health.

Self-efficacy in Everyday Life: Where It Really Matters

The beauty of this concept is that it applies to nearly every area of life. Let’s look at a few concrete examples:

• Work and Career: Those who believe they can successfully negotiate a salary prepare differently—and present themselves differently. Studies show that self-efficacy is one of the strongest predictors of professional success and perseverance in demanding jobs.
• Health Behavior: Bandura (1997) devoted an entire chapter of his seminal work to the role of self-efficacy in the health sector. Those who believe they can quit smoking have significantly better chances of success than someone who has already given up.
• Education and learning: Students with high self-efficacy show more perseverance when tackling difficult tasks, are more likely to seek help, and view mistakes as learning opportunities rather than as proof of their inability.
• Personal relationships: Here, too, expectations of competence play a role. Those who are convinced they can resolve conflicts constructively approach difficult conversations with greater openness.

In all these areas, the same principle applies: It is not about being naive or denying difficulties. High self-efficacy means realistic confidence—the belief that one can handle whatever comes their way.

The Difference Between Self-Efficacy and Self-Confidence

These two terms are often used interchangeably in everyday life—yet they describe different psychological constructs. Self-confidence is a broad, affective feeling: I like myself; I stand by myself. It is more general and often emotionally charged.

Self-efficacy, on the other hand, is more cognitive and task-specific. It isn’t about saying, “I’m good,” but rather, “I can accomplish this task.” You can like yourself very much and still believe you’re not a good public speaker—or conversely, you can have serious doubts about yourself as a person and still know that you’re an excellent programmer.

This distinction is therapeutically and practically significant. Because it is possible—and often more sensible—to work on self-efficacy in a specific area rather than generally trying to build “more self-confidence.” The latter often feels vague; the former provides clear starting points.

Recognizing Low Self-Efficacy: Typical Thought Patterns

Before you can change something, you have to recognize it. People with low self-efficacy often exhibit characteristic thought and behavior patterns:

• “This is too difficult for me anyway.” – Tasks are prematurely deemed unsolvable.
• “If this doesn’t work out, it proves I never could do it.” – Failures are overgeneralized.
• Avoidance behavior: Challenges are sidestepped before they’re even truly attempted.
• Giving up quickly after initial setbacks.
• Strong dependence on external validation due to a lack of inner conviction.

Important: Such patterns are not character flaws. They often arise from repeated negative experiences, critical messages in childhood, or simply a lack of opportunities to experience one’s own strengths. Research—and the good news—shows that these beliefs can be changed.

Building Self-Efficacy: Concrete, Scientifically Backed Methods

Practical strategies can be derived from the four sources described by Bandura (1997). None of them is a quick fix—but all are proven and effective.

Actively create small successes

Break down big goals into manageable subgoals. If you set out to run a marathon, start with a 10-minute jog—not a 20-kilometer run. Every subgoal you check off is real proof of your ability. Feel free to keep a small success journal: Write down one thing every day that you’ve completed or mastered. This trains you to focus on your own resources.

Choose role models consciously

Seek out people who started from similar circumstances and achieved what you envision. Biographies, podcasts, communities—all of these can provide vicarious experiences. The goal isn’t envy, but guidance: What they did, I could do too.

Change your inner dialogue

Verbal self-affirmation can also come from within. Replace automatic self-criticism with realistic, encouraging phrases. Not blind praise—but concrete recognition: “I handled a similar situation well last time. I have what it takes.”

Interpreting physical sensations correctly

If your heart starts racing before an important situation, practice interpreting it as activation energy. This technique—also known as cognitive reappraisal—has been proven effective in several studies for reducing performance anxiety and strengthening self-efficacy.

Creating psychological safety

Self-efficacy thrives in environments that view mistakes as part of the learning process. Surround yourself with people who make you feel safe to try new things—and be that kind of person for others.

Self-Efficacy in Therapy and Counseling

The concept is not only relevant to personal development—it has established itself as a key element in various therapeutic approaches. In cognitive behavioral therapy (CBT), strengthening self-efficacy is an explicit goal: patients learn to identify dysfunctional beliefs about their own incompetence and gradually replace them with experience-based counterevidence.

Self-efficacy also plays a central role in positive psychology. Researchers such as Martin Seligman and Mihaly Csikszentmihalyi built their concepts of resilience and flow on similar basic assumptions: Human beings are not passive objects of circumstances, but active shapers of their own experiences—provided they are aware of and utilize this power to shape their lives.

In their research on general self-efficacy, Schwarzer and Jerusalem (1995) also demonstrated that these beliefs are closely linked to stress resilience. People with high self-efficacy are more likely to view stressful events as challenges rather than threats—a distinction that has enormous long-term implications for coping with chronic pressure.

Self-efficacy as a lifelong process

Perhaps the most important lesson from research is this: self-efficacy is not a state that you achieve once and then possess forever. It is a dynamic, constantly evolving system of beliefs—influenced by new experiences, changing life circumstances, and deliberate practice.

This also means: It is normal for self-efficacy to decline during new phases of life—such as when changing jobs, going through a breakup, or starting college. In such moments, it is particularly helpful to look back on one’s own life story: When have I overcome a difficult situation before? These memories are not a nostalgic exercise, but genuine emotional and cognitive evidence of one’s own capacity to act.

In this context, Bandura (1997) emphasized that it is not a person’s objective abilities but their belief in their abilities that guides behavior in decisive moments. Two people with identical skills can behave completely differently—depending on what they believe about themselves. This is both a sobering and an empowering realization: Your belief in yourself is something you can shape.

Action prompt for today: Take five minutes now and write down three situations in which you overcame a challenge—no matter how big or small. Bring the memory vividly to life: What did you do? What did it require of you? What does it say about you? This brief exercise isn’t sentimental—it’s an evidence-based method for activating the first and strongest source of your self-efficacy: your own experiences of success.

What exactly is self-efficacy and where does the term come from?

Self-efficacy refers to a person's belief that they are able to cope with certain tasks or challenges on their own. The term was coined by psychologist Albert Bandura, who published his influential Self-Efficacy Theory in 1977. In German, it is often also referred to as Kompetenzerwartung or Selbstwirksamkeitserwartung. It is not about general self-confidence, but about the specific conviction: I can achieve this specific goal through my actions.

Is it really possible to actively strengthen self-efficacy?

Yes, and very specifically. Bandura (1997) described four sources of self-efficacy from which direct methods can be derived: gaining your own sense of achievement (e.g. by breaking down goals into small steps), learning from role models, developing encouraging self-talk and interpreting physical tension as energy rather than weakness. The most effective method is your own experiences of success - they provide the brain with irresistible evidence of your own ability to act.

What is the difference between self-efficacy and self-confidence?

Self-confidence is a broad, more emotional feeling of general trust in oneself. Self-efficacy, on the other hand, is more specific and cognitive: it always relates to a specific area or a specific task. So you can have high self-confidence and still have low self-efficacy in a specific area - for example, in public speaking. For personal development, it is often more helpful to work on self-efficacy in a specific area than to work on more self-confidence in general.

What does research say about the effects of high self-efficacy?

The findings are clearly positive. Schwarzer and Jerusalem (1995) showed that high general self-efficacy is associated with lower levels of depression and anxiety, better health, higher job satisfaction and more effective stress management. Bandura (1997) also documented correlations with greater perseverance in difficult tasks, more courageous goal setting and a more constructive interpretation of setbacks. Self-efficacy is now regarded as one of the key protective factors for mental health and resilience.

Can self-efficacy be too high?

Theoretically, yes. Excessive self-efficacy - i.e. a clear overestimation of one's own abilities - can lead to a willingness to take risks that is not covered by real skills. In practice, however, this is less of a problem than low self-efficacy. Bandura therefore deliberately spoke of realistic confidence: the goal is not blind optimism, but a fair assessment of one's own possibilities based on real experience. According to research, a certain positive bias - i.e. a slight overestimation - can even have a motivational effect.

How is self-efficacy related to resilience?

Self-efficacy is a central component of resilience - the ability to survive difficult situations and grow from them. People who believe they can cope with what comes their way are more willing to take action in times of crisis, actively look for solutions and are less likely to give up prematurely. Schwarzer and Jerusalem (1995) were able to show that people with high self-efficacy assess stressful events more often as challenges rather than threats - a cognitive attitude that contributes significantly to mental resilience in the long term.
