Social and Behavioural Science Theories: Social Cognitive Theory and Bioecological Theory

Introduction to Social and Behavioural Science Theories

The study of Social and Behavioural Science Theories is essential for understanding how individuals interact with their environments and how health-related behaviours are formed and maintained. Presented by Dr. Joyce Komesuor from the University of Health and Allied Sciences, these notes explore two primary frameworks: Social Cognitive Theory and Bioecological Theory. These theories provide a comprehensive understanding of the dynamic relationships between personal factors, environmental contexts, and human actions, and they serve as the foundation for developing effective public health interventions.

Overview of Social Cognitive Theory

Social Cognitive Theory (SCT) has its roots in Social Learning Theory (SLT), which was originally developed in the 1960s by Albert Bandura. In 1986, the theory evolved into Social Cognitive Theory to better account for the cognitive processes involved in learning. SCT posits that learning occurs within a social context through a dynamic and reciprocal interaction involving the person, the environment, and the behaviour. The theory is unique in that it considers the specific ways individuals acquire and maintain behaviours while simultaneously accounting for the social environment in which these behaviours are performed.

While many health promotion theories focus primarily on the initiation of a behaviour, SCT emphasizes the maintenance of behaviour. In the field of public health, the long-term maintenance of healthy habits is considered the true goal. Consequently, the objective of Social Cognitive Theory is to explain and predict how individuals regulate their behaviour via internal control and external reinforcement to achieve goal-directed actions that persist over time.

Key Constructs of Social Cognitive Theory

Social Cognitive Theory is built upon several core constructs that explain human behaviour. The central concept is Reciprocal Determinism, which describes the continuous, multidirectional interaction between the Person, the Environment, and the Behaviour. The Person represents the individual with their unique set of learned experiences and cognitive traits. The Environment refers to the external social and physical context, while Behaviour involves the specific responses to stimuli used to achieve goals.

Behavioural Capability is another vital construct, referring to an individual's actual ability to perform a specific behaviour. This necessitates both the essential knowledge of what to do and the practical skills of how to do it. SCT suggests that people learn from the consequences of their actions, and these consequences eventually influence the environment in which they live. Observational Learning focuses on the idea that people can witness a behaviour performed by others and subsequently reproduce those actions. This process is commonly known as "modeling." If individuals see a successful demonstration of a behaviour, they believe they can also complete that behaviour successfully.

Reinforcements are the internal or external responses to a person's actions that determine the likelihood of continuing or stopping a behaviour. These reinforcements can be self-initiated or derived from the external environment and can be either positive or negative. This construct is considered the bridge that most closely links the reciprocal relationship between behaviour and environment. Expectations refer to the anticipated consequences of a person's behaviour. These outcome expectations may be health-related or non-health-related. Individuals typically anticipate the results of their actions before they engage in them, and these expectations, which derive largely from previous experiences, influence the success of the behaviour. A related concept, Expectancies, refers to the subjective value an individual places on a particular outcome.

Self-efficacy is perhaps the most well-known construct of SCT, though it has since been adopted by other frameworks like the Theory of Planned Behaviour. It represents the degree of confidence a person has in their ability to perform a behaviour successfully. Self-efficacy is shaped by an individual's specific capabilities, personal factors, and environmental factors, including both barriers that hinder progress and facilitators that enable it.

Interactions Between Personal, Environmental, and Behavioural Factors

Human behaviour is determined by the intersection of three specific factors often categorized as Cognitive, Environmental, and Behavioural. Cognitive Factors, also known as "Personal Factors," include an individual's existing knowledge, their expectations about outcomes, and their attitudes toward a specific action. Environmental Factors encompass social norms, access to resources within the community, and an individual's influence on others, such as their ability to change their own environment.

Behavioural Factors involve the actual skills an individual possesses, the amount of practice they have had, and their level of self-efficacy. These three categories do not exist in isolation; they are constantly influencing one another to determine how a person behaves in any given situation. Interventions designed to change health behaviour must recognize this complexity by creating enabling structural and social environments. Effective interventions should promote role models who successfully practice desired behaviours and experience clear benefits. This can be achieved through entertainment education, such as radio and TV dramas, or community events where individuals performing healthy behaviours are publicly celebrated.

Foundations of Bioecological Theory

The Bioecological Theory, or ecological systems theory, was developed by Urie Bronfenbrenner in 1979. This theory views child development and human behaviour as a complex system of relationships influenced by multiple levels of the surrounding environment. These levels range from immediate settings, such as family and school, to broad societal factors like cultural values, laws, and customs. The primary tenet of the theory is that behaviours both shape and are shaped by the social environment. The principles of Bioecological Theory align closely with Social Cognitive Theory, as both suggest that creating an environment conducive to change is necessary for people to adopt healthy behaviours.

Levels of Influence and Ecological Systems

The Bioecological Theory identifies five distinct levels of influence that affect human development and behaviour: the individual level, the interpersonal level, the organizational level, the community level, and the public policy level. These levels are further organized into nested systems that interact with one another. At the core is the Individual, defined by their identities, traits, characteristics, age, gender, and socioeconomic status (SES). Surrounding the individual is the Microsystem, which includes immediate social relationships such as family, parents, peers, school teachers, and church groups.

Beyond the Microsystem is the Mesosystem, which refers to the interactions between different parts of the individual’s microsystem, such as the relationship between a person's parents and their school teachers. The Exosystem includes broader environments that do not involve the individual directly but still exert influence, such as the mass media, social services, the parent's workplace and its policies, and the safety and resources of the neighborhood. The Macrosystem is the outermost layer, consisting of the larger cultural and societal context, including cultural values, beliefs, politics, and national laws. These systems interact through the Chronosystem (implied by the complex interplay over time), involving everything from home environments and parent mental health to supportive school and religious settings.

Practical Application and Multi-level Interventions

Health behaviours are rarely the result of a single factor; they are shaped by a complex interplay of determinants across multiple levels. For example, the likelihood of an individual engaging in regular physical activity is influenced by their self-efficacy at the individual level, the amount of social support they receive from friends and family at the interpersonal level, and their perceptions of crime and safety within their neighborhood at the community level. Understanding these layers allows public health practitioners to provide the necessary information, tools, and skills to increase a person's perceived ability to engage in healthy behaviours.

Questions & Discussion

Using the Social Cognitive Theory, explain how a first-year university student may learn positive study habits by observing senior students on campus. In your answer, discuss any three key concepts of Social Cognitive Theory and provide relevant examples.

A student might apply Observational Learning (Modeling) by watching a senior student use a specific library technique or a digital organization tool; by seeing the senior's success, the freshman learns to reproduce the same habit. The student would also require Behavioural Capability, meaning they must not only see the habit but also gain the specific skills (like learning to use the software) to perform it. Finally, Reinforcement plays a role; if the freshman sees the senior receiving praise or high grades for their study habits (external reinforcement), or if the freshman feels a sense of accomplishment after trying the method (internal reinforcement), they are more likely to maintain the habit. Reciprocal Determinism is also at play, as the student's new study behaviour might prompt other students to join them, thereby changing the social environment of their dormitory or study group.
