Why study theory?
Provides a framework Offers logic for observations and explanations How and why people act Important for nurses to combine theory, practice, and research Nurses assess responses to illness and treatments

Theory
Organized and logical set of statements about a subject, frameworks to clarify, to make sense of. Human Development Theory: Models intended to account for how and why people become who they are, tries to explain and predict human behavior.

Growth and Development
Growth: Quantitative changed, measured and compared to norms Height, weight compared to normal growth charts Development: Qualitative, progressive, continuous process of change leading to a functional capacity Child crawls, rolls over, walks

Four Areas of Developmental Theories
Biophysical-How do we grow, change, age Psychosocial-Personality & behavior Cognitive-Thinking, intellect

Moral-Knowing right from wrong, ethics

Biophysical Developmental Theories
Gesell’s Theory: Grow according to our own genetic blueprint and pace, growth is directed by gene activity, environmental factors can modify pattern of development Genetic Theory of Aging: DNA function of cell lifespan, programmed cell death, accounts for longevity in families

Biophysical Developmental Theories
Nongenetic Cellular Theories: Looks at cell rather than DNA, “wear and tear” theory, our bodies just wear out. Free Radical Theory Physiological Theories of Aging: 1) Breakdown of performance of a single organ 2.) Impairment of physiological control mechanisms

Erik Erikson
Student of Anna Freud Evolutionary process: Biological, psychological, and social events contribute to readiness for each task/stage Added 3 adult stages to Sigmund’s model

Erikson’s Stages of Psychosocial Development
Trust vs. Mistrust Autonomy vs. Shame Initiative vs. Guilt Industry vs. Inferiority Identity vs. Role Confusion Intimacy vs. Isolation Generativity vs. Stagnation Integrity vs. Despair

Jean Piaget Cognitive Development Theory
How we think, learn to reason, exercise judgment, have intellectual organization Observed children Defined 4 periods that children move through: Sensorimotor (Birth-2 yrs) Preoperational (2-7 yrs.) Concrete (7-11 yrs) Formal (11 yrs-adult)

Jean Piaget Moral Development
Stages of moral development influenced by environment Observed boys, ages 5-13 yrs.

Moral Development Theories
How we acquire moral values, are guided by morals, how we treat others based on morals Jean Piaget-Environmental influences Lawrence Kohlberg-Cognitive and moral linked, expanded Piaget’s work, defined 3 levels with 6 stages of moral development

Lawrence Kohlberg Moral Development Theory
Level 1- Preconventional Stage 1- Punish and Obey Stage 2- Instrumental Relativist Level 2- Conventional Stage 3- Good boy/Nice girl Stage 4- Society Maintenance Level 3- Post-Conventional Stage 5-Social Contract Stage 6- Universal Ethics

Analysis
Theories give nurses some answers on why and how people react, respond as they do Human behavior is complex No one theory answers all questions All theories are multi-dimensional, not linear, they are guidelines
