A theory is a way of explaining something that we can observe, such as how people behave and change throughout their lives. A theory helps us understand why people do what they do, and how they are affected by the world around them.
Some theories are very broad and can explain many different aspects of life, such as how we think, feel, learn, grow, and relate to others. These are called comprehensive theories, and they are useful because they can help us understand people at any stage of life.
Other theories are more narrow and focus on a specific area of human behavior or development, such as how we solve problems, make decisions, express our sexuality, break the law, or cope with aging. These are called limited-scope theories, and they are useful because they can help us understand people in certain situations or contexts.
A notable theorist is Ivan Pavlov.

Operant learning theory, created by B.F. Skinner and influenced by E.L. Thorndike, explains how we learn from the consequences of our actions. According to this theory, we are more likely to repeat a behavior if it leads to a good outcome (reward) and less likely to repeat it if it leads to a bad outcome (punishment). This type of learning, known as operant conditioning, can be used in various situations such as teaching, counseling, training animals, and changing behavior.
In operant conditioning, the consequences of a behavior change the likelihood of that behavior occurring in the future. There are two main types of consequences: reinforcement and punishment. Reinforcement increases the likelihood of a behavior occurring, while punishment decreases it.
There are four types of reinforcement: positive reinforcement, negative reinforcement, positive punishment, and negative punishment.
For more information on this theory read Stephen E. Wong's chapter on Operant Learning Theory.
Cognitive behavioral theory explains how an individual’s thoughts affect their feelings and actions. Negative or unrealistic thoughts can lead to negative feelings and behaviors, such as depression, anxiety, anger, or guilt. Cognitive behavioral therapy (CBT) is a type of psychotherapy that helps individuals change their thoughts to improve their mood and behavior. CBT teaches skills such as facing fears, challenging negative thoughts, solving problems, and relaxing the body and mind.
CBT is based on the principle that an individual’s thoughts, feelings, and behaviors are interconnected. By identifying and challenging negative thoughts, individuals can develop more helpful and realistic thoughts. CBT also helps individuals develop new skills and behaviors to cope with difficult situations.
The core principles of CBT include collaboration between the therapist and client, Socratic questioning to identify and challenge negative thoughts, homework assignments to practice skills learned in therapy, a focus on the present, and an emphasis on coping skills. CBT has been shown to be effective in treating a wide range of psychological problems, including anxiety, depression, and eating disorders. It is a short-term, focused therapy that can help individuals change their thoughts, feelings, and behaviors.

Attachment theory, developed by John Bowlby, explains how individuals form close and lasting relationships with others. According to this theory, infants have a biological need to form attachments with their caregivers in order to survive and thrive. These early attachments shape an individual’s patterns of relating to others, known as attachment styles. There are four main attachment styles: secure, anxious-avoidant, anxious-ambivalent, and disorganized. Secure attachment is associated with positive emotional development, while insecure attachment is associated with negative emotional development.
Attachment disorders are a group of mental health conditions characterized by problems with attachment. These disorders can be caused by a variety of factors, including neglect, abuse, and trauma. Treatment for attachment disorders typically involves psychotherapy, such as attachment-based therapy.
Attachment-based therapy is specifically designed to help individuals with attachment disorders. The therapy focuses on helping the client develop a secure attachment with the therapist and learn how to form secure attachments with others. The therapy typically involves providing a safe and supportive environment for the client to explore their thoughts, feelings, and experiences; exploring the client’s attachment history; providing the client with the care and support they missed out on in early childhood; and teaching the client skills for managing their emotions and forming healthy relationships.
John Bowlby was a key theorist in the development of Attachment theory and Mary Ainsworth research provided empirical support to Bowlby’s theoretical work.

Psychosocial theory is a biopsychosocial approach to human development that emphasizes the interaction between biological, psychological, and social factors. Erik Erikson developed this theory, which proposes that individuals progress through eight stages of psychosocial development throughout their lives.
Each stage is characterized by a psychosocial crisis that must be resolved in order to move on to the next stage. The eight stages are:
The successful resolution of each stage leads to the development of a healthy personality. The unsuccessful resolution of a stage can lead to the development of problems in later life.
Psychosocial theory has been used to understand a wide range of human behaviors and problems, including personality disorders, addiction, and mental illness. It has also been used to develop interventions for these problems.
Erikson believed that each stage of psychosocial development is characterized by a conflict between two opposing forces. The successful resolution of each conflict leads to the development of a positive personality trait, while the unsuccessful resolution leads to the development of a negative personality trait.
For example, in the trust vs. mistrust stage, the infant is faced with the conflict between trusting their caregiver and mistrusting them. If the infant is able to trust their caregiver, they will develop a sense of trust, which is a positive personality trait. However, if the infant is unable to trust their caregiver, they will develop a sense of mistrust, which is a negative personality trait.
Psychosocial theory has been criticized for being too deterministic. Some critics argue that the theory does not allow for individual differences or free will. However, Erikson argued that the theory is not deterministic, and that individuals have the ability to shape their own development.
The book Ego Identity: A Handbook for Psychosocial Research by James E. Marcia is based on the work of Erik Erikson. Marcia's theory of ego identity builds on Erikson's theory by proposing that ego identity is a multidimensional construct that includes exploration and commitment. Exploration is the process of trying out different roles and identities, while commitment is the process of making a decision about who you are and what you believe in.
Marcia's theory has been influential in the field of psychology, and it has been used to understand a variety of topics, such as adolescent development, career choice, and mental health.

Person-centered therapy is a humanistic approach to psychology that emphasizes self-actualization and the individual's capacity for growth and change. Developed by Carl Rogers, the theory states that all people have an innate drive to become fully functioning individuals. The best way to help people achieve this goal is to provide them with a supportive and non-judgmental environment.
The core conditions of person-centered therapy are
When these conditions are present, clients can explore their thoughts and feelings without fear of judgment or rejection. This can lead to increased self-awareness, self-acceptance, and personal growth.
Person-centered therapy has been used to treat a variety of mental health problems, including anxiety, depression, and personality disorders. It has also been used in other settings, such as education and business, to improve communication and relationships.

Genetic Theory is a biological approach that explores the role of genes in human behavior. According to this theory, genes can influence behavior including the transmission of traits from parents to children, mutations that can lead to changes in gene function, and interactions between genes and the environment.
Human service and helping professionals should be aware of the role of genes in human behavior but should also be careful not to overemphasize their role. Social workers need to be aware of the role of genetics in human development and how it can affect their clients. For example, social workers may need to provide genetic counseling to clients who are at risk for certain diseases or who are considering having children. Social workers may also need to advocate for policies that promote genetic health and prevent discrimination against people with genetic conditions.

General systems theory, developed by Von Bertalanffy, is a multidisciplinary framework that seeks to understand the common principles underlying all systems, whether biological, physical, or social. This theory proposes that all systems are characterized by properties such as wholeness, interdependence, homeostasis, equifinality, and morphogenesis. By understanding these common principles, one can gain a better understanding of the world. General systems theory is a more general theory that can be applied to all types of systems. This theory influenced ecosystems theory which focused on the different parts of ecological systems.
Ecosystems theory, developed by Urie Bronfenbrenner, is a biopsychosocial framework that views individuals as being embedded in a complex system of interrelated parts, including their family, community, and larger society. This theory emphasizes the importance of interactions between individuals and their environment and how these interactions can affect a person’s development and well-being.
According to ecosystems theory, individuals are nested within a series of concentric circles or ecological systems. The innermost circle is the microsystem, which includes the individual’s immediate environment such as their family, friends, and school. The mesosystem consists of the connections between the microsystems, such as the relationships between a child’s family and their school. The exosystem is the next circle out and includes social institutions that indirectly affect the individual, such as their parents’ workplace or the neighborhood they live in. The macrosystem is the outermost circle and includes larger cultural and societal influences on the individual, such as their country’s economic system or political climate.
Ecosystems theory is used in social work to understand the factors that contribute to a person’s problems and to develop interventions that address these factors. For example, a social worker might use ecosystems theory to understand how a child’s behavior problems are related to their family dynamics, school environment, and neighborhood. The social worker could then develop interventions that address these factors, such as family therapy, school-based interventions, or community organizing.

Small group theory encompasses a multidisciplinary collection of theoretical frameworks that explain the complex dynamics within small groups. These groups, often used for therapeutic, educational, or task-oriented purposes, are the focus of study. By drawing from sociology, psychology, and social work, small group theory provides a comprehensive understanding of the social interactions, individual psychology, and emotional experiences that shape group dynamics. While various theoretical perspectives exist, they all acknowledge the intricate interplay of these factors within small group settings.
Small group work offers numerous benefits, including increased efficiency, social support, and interpersonal learning. Groups allow practitioners to work with multiple individuals simultaneously, reducing costs and increasing access to services. They also provide a sense of belonging and support for individuals facing similar challenges, fostering validation and hope. Additionally, groups offer a safe space for individuals to examine their interpersonal patterns, receive feedback, and practice new skills. While these benefits are significant, it's important to acknowledge potential risks such as breaches of confidentiality, dependency, scapegoating, groupthink, and domination.
Kurt Lewin was a pioneering social psychologist whose field theory emphasized the interconnectedness of individuals and their social environments. He coined the term "group dynamics" and stressed the importance of understanding the forces that shape behavior within groups.
Wilfred R. Bion was a psychoanalyst who studied group dynamics, he focused on the unconscious processes at play within groups, identifying "basic assumptions" that can hinder or facilitate group functioning. His work highlighted the importance of addressing both overt and covert group dynamics to achieve therapeutic goals.
Yvonne M. Agazarian has developed Systems-Centered Therapy (SCT) for groups. Building on systems theory and emphasizing the importance of understanding groups as complex, interconnected systems her work provides specific techniques for facilitating group process and promoting individual and group transformation.
Irving D. Yalom pioneered the interpersonal learning theory which highlighted the role of interpersonal dynamics in psychological distress and growth. He emphasized the importance of creating a here-and-now focus, facilitating emotional experiences, and promoting interpersonal learning within the group setting.
