Page 2: Early Theories of Behavior

  • Behavior explained from a psychological basis with three common characteristics:

    • Regulated psychically by the subconscious.

    • Deviant behavior viewed as a symptom of disease or disorder.

    • Changes in behavior occur through self-insight and analysis with a therapist.

Page 3: New Approach in the 1960s

  • A shift in understanding behavior emphasized:

    • Behavior results from interplay between personal, behavioral, and environmental factors.

    • Deviant behavior is not merely a symptom of disease or disorder.

Page 4: Self-Efficacy Theory

  • Self-efficacy: Introduced by Bandura (1977)

    • Refers to individuals’ perceptions about their abilities to engage in specific behaviors.

    • A form of self-confidence that is situation-specific.

Page 5: Defining Self-Efficacy

  • Self-efficacy is defined as an individual’s belief in their capabilities to successfully carry out actions to meet specific task demands - Albert Bandura.

Page 6: Self-Efficacy Characteristics

  • Self-efficacy is related to confidence in ability to take action and persist despite challenges.

Page 7: Essence of Self-Efficacy Theory

  • Key idea: People will only attempt tasks they believe they can accomplish.

    • E.g. “I think I can, I think I can...”

Page 8: Characteristics of High Self-Efficacy

  • Individuals with strong self-efficacy:

    • See difficult tasks as challenges to master.

    • Set goals and maintain commitment.

    • Approach challenges with confidence.

    • Exhibit lower levels of depression and stress.

Page 9: Characteristics of Low Self-Efficacy

  • Individuals with low self-efficacy:

    • View difficult tasks as threats and may avoid them.

    • Tend to give up when faced with failure.

    • Quickly lose confidence in their abilities.

    • Experience higher rates of depression and stress.

Page 10: Sources of Self-Efficacy

  • Four primary sources:

    • Performance Outcomes:

      • Success or failure influences perceptions of competence.

      • Past performance history is key to self-efficacy levels.

    • Verbal Persuasion:

      • Encouragement from others can bolster self-efficacy.

    • Vicarious Experiences:

      • Observing others performing tasks can enhance or diminish self-efficacy.

    • Physiological Feedback:

      • Physical and emotional reactions influence self-efficacy beliefs.

Page 11: Mastery Experience

  • Previous successful experiences boost self-efficacy.

    • Similarity between past and present tasks affects strength of self-efficacy.

  • Building self-efficacy requires:

    • Trying new and challenging tasks.

    • Overcoming obstacles.

    • Persisting through difficult situations.

Page 12: Vicarious Experience

  • Learning through observing others (“modeling”).

    • Success of similar others enhances self-efficacy.

    • Failure of models can threaten self-efficacy.

Page 13: Social Persuasion

  • Use of verbal/nonverbal communication to boost self-efficacy.

    • Effectiveness increases when encouragement comes from knowledgeable sources.

    • Discouragement can harm self-efficacy.

Page 14: Physiological and Emotional Feedback

  • Physical and emotional states impacting self-efficacy:

    • Negative feelings (fear, anxiety) can decrease self-efficacy.

    • Positive feelings (joy, excitement) can enhance self-efficacy.

Page 15: Summary of Self-Efficacy Components

  • Key Components:

    • Somatic/Emotional state

    • Vicarious experiences

    • Verbal persuasion

    • Mastery experience

Page 16: General Self-Efficacy Scale

  • Purpose: Assess perceived self-efficacy related to daily hassles and adaptations to stress.

    • Designed for adults and adolescents. Not suitable for children under 12.

Page 17: General Self-Efficacy Scale Questions

  • Common statements include:

    • "I can manage to solve difficult problems..."

    • Rated on a scale from 1 = Not at all true to 4 = Exactly true.

Page 18: Barriers to Self-Efficacy Scale

  • The BARSE assesses perceived capabilities to exercise in the face of barriers over two months.

    • Uses a 100-point percentage scale for confidence ratings.

    • Scores calculated based on the total ratings.

Page 19: Specific Barrier Statements

  • Example barrier statements include:

    • Weather conditions, boredom, lack of interest, pain, social factors, conflicts, self-consciousness.

Page 20: Application Exercise

  • Create a behavior you want to measure and develop 10 questions/statements based on the model.

    • Consider potential barriers and include a measurement scale (e.g., Likert).
