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).
