Health Promotion (PCL 503) Dr S. Showande Introduction: Health promotion is a fundamental aspect of public health and healthcare systems. It focuses on empowering individuals, communities, and populations to take control of their health and well-being, thereby improving overall health outcomes. Definition of Health Promotion Health promotion is defined as the process of enabling people to increase control over and improve their health. It involves a combination of educational, political, environmental, and organizational interventions that aim to improve the health and well-being of individuals, communities, and populations. The Core Principles of Health Promotion 1. Empowerment: Health promotion aims to empower individuals and communities to take control over the factors that influence their health. This principle emphasizes the importance of providing people with the knowledge, resources, and support they need to make informed decisions about their health and well- being. By empowering individuals, health promotion seeks to foster a sense of ownership and responsibility for one's health, leading to more sustainable and meaningful behavioural change. Levels of Empowerment A. Individual Empowerment Developing personal skills and knowledge Increasing self-efficacy and confidence Promoting active participation in healthcare decisions B. Community Empowerment Strengthening community networks and social support systems Facilitating community involvement in health-related decision-making Promoting collective action and advocacy for community health needs C. Organizational Empowerment Fostering organizational policies and structures that support empowerment Encouraging employee participation and decision-making Promoting organizational cultures that value empowerment Strategies for Empowerment in Health Promotion A. Education and Skill-Building Providing accessible and relevant health information Developing individual and community skills (e.g., problem-solving, communication, decision-making) Promoting health literacy B. Participatory Approaches  Involving individuals and communities in the design, implementation, and evaluation of health promotion programs Encouraging shared decision-making between healthcare providers and patients Supporting community-based initiatives and grassroots organizations C. Building Partnerships and Collaborations Fostering partnerships between healthcare providers, community organizations, and policymakers Facilitating multi-stakeholder engagement in health promotion efforts Lever 2. Equity: Another fundamental principle of health promotion is equity, which ensures that all individuals and groups have fair and equal access to health resources and opportunities. This principle recognizes the importance of addressing social determinants of health and striving to reduce health disparities and inequities. Health promotion interventions should be designed and implemented in a way that promotes fairness and social justice, taking into account the unique needs and circumstances of diverse populations. 3. Holistic Approach: Health promotion adopts a holistic approach that recognizes the interdependence of physical, mental, emotional, and social aspects of health. This principle emphasizes the interconnectedness of various dimensions of health and well-being and underscores the importance of addressing the whole person in health promotion efforts. By considering the holistic nature of health, interventions can be designed to promote comprehensive wellness and address the complex interactions between different aspects of health. 4. Multisectoral Collaboration: Health promotion involves collaboration across various sectors, such as education, environment, social services, and more. This principle acknowledges that promoting health requires coordinated efforts from multiple stakeholders and disciplines. By engaging diverse sectors, health promotion can leverage resources, expertise, and perspectives to create comprehensive and sustainable solutions to health challenges. 5. Evidence-based Practice: The principle of evidence-based practice underscores the importance of basing health promotion interventions on the best available scientific evidence. This principle emphasizes the use of rigorous research, evaluation, and data-driven decision-making to ensure that interventions are effective, safe, and tailored to the specific needs of the target populations. By prioritizing evidence-based approaches, health promotion seeks to maximize the impact of interventions and promote continuous learning and improvement in the field. Theoretical Frameworks in Health Promotion Theoretical frameworks in health promotion provide a foundation for understanding and implementing effective health promotion interventions. These frameworks help to guide the design, implementation, and evaluation of health promotion programs and initiatives. Health Belief Model I. Introduction to the Health Belief Model A. Definition and Overview The Health Belief Model (HBM) is a widely used theoretical framework in health promotion and disease prevention. It aims to explain and predict health-related behaviors by focusing on the attitudes and beliefs of individuals. B. Historical Background The HBM was developed in the 1950s by a group of social psychologists in the U.S. Public Health Service. It was initially created to understand the failure of people to participate in programs to prevent and detect disease. II. Key Constructs of the Health Belief Model A. Perceived Susceptibility An individual's subjective perception of the risk of contracting a health condition or disease. Influences the likelihood of engaging in health-promoting behaviours. B. Perceived Severity An individual’s belief about the seriousness of a health condition or disease and its potential consequences. Includes both medical and social consequences. C. Perceived Benefits An individual’s belief in the effectiveness of a recommended action to reduce the threat of a health condition or disease. Influences the likelihood of engaging in the recommended behaviour. D. Perceived Barriers An individual’s belief about the tangible and psychological costs of engaging in a recommended health behaviour. Includes factors that may discourage or prevent the individual from taking action. E. Cues to Action Factors that trigger or motivate an individual to engage in a health-promoting behavior. Can be internal (e.g., symptoms) or external (e.g., media campaigns, reminders from healthcare providers). F. Self-Efficacy An individual’s belief in their ability to successfully perform a recommended health behaviour. Influences the initiation and maintenance of health-promoting behaviours. III. Application of the Health Belief Model A. Predicting Health Behaviors  The HBM is used to predict the likelihood of an individual engaging in a health-promoting behavior. The model suggests that the more an individual perceives a threat and the greater the perceived benefits of the recommended action, the more likely the individual is to engage in the behaviour. B. Designing Health Promotion Interventions The HBM can guide the development of health promotion programs and interventions. Interventions can target the model's key constructs to influence individual beliefs and increase the likelihood of behaviour change. C. Evaluating Health Promotion Programs The HBM can be used to evaluate the effectiveness of health promotion programs by assessing changes in the key constructs. Evaluating the impact of interventions on the HBM constructs can provide insights into the mechanisms of behaviour change. IV. Limitations and Criticisms of the Health Belief Model A. Oversimplification of Behavior The HBM may oversimplify the complex nature of health behaviours, which are influenced by various social, cultural, and environmental factors. B. Lack of Consideration for Habitual Behaviors The model may not adequately explain the maintenance of health behaviours, particularly those that have become habitual. C. Individualistic Approach The HBM primarily focuses on individual-level beliefs and may not address the broader social and contextual factors that influence health behaviors. D. Inconsistent Empirical Support The empirical evidence supporting the predictive power of the HBM has been mixed, with some studies finding stronger support than others. V. Conclusion The Health Belief Model provides a valuable framework for understanding and predicting health-related behaviors. It can be effectively used in the design, implementation, and evaluation of health promotion Transtheoretical Model (TTM) Developed by Prochaska and DiClemente in the 1980s. Describes the process of behavioural change as a series of stages: pre-contemplation, contemplation, preparation, action, maintenance, and termination. Emphasizes the importance of tailoring interventions to an individual's stage of change. I. Introduction to the Transtheoretical Model A. Definition and Overview The Transtheoretical Model (TTM), also known as the Stages of Change Model, is a comprehensive theory of behavioural change. It describes the process of how people intentionally modify their behavior, cognitions, and emotions to achieve a desired outcome. B. Historical Background  The TTM was developed in the late 1970s and early 1980s by James Prochaska and Carlo DiClemente. It was initially used to understand the process of smoking cessation, but has since been applied to a wide range of health-related behaviors. II. Key Constructs of the Transtheoretical Model A. Stages of Change Precontemplation: Individuals are not considering changing their behaviour in the foreseeable future. Contemplation: Individuals are considering changing their behaviour but have not yet taken action. Preparation: Individuals are ready to take action and have a plan to change their behaviour. Action: Individuals have made overt changes to their behaviour and are actively working to maintain the change. Maintenance: Individuals have been able to sustain the behavioural change for a significant period and are working to prevent relapse. Termination: individuals considers disengaging from the behavioural change B. Processes of Change Cognitive and Affective Processes: Involve changes in thoughts, feelings, and beliefs that facilitate behaviour change. Behavioral Processes: Involve changes in actions and behaviours that support the desired behaviour change. C. Decisional Balance The weighing of the perceived pros and cons of changing a behaviour. The balance between the perceived benefits and barriers of change influences an individual’s readiness to change. D. Self-Efficacy An individual’s confidence in their ability to perform a specific behavior in the face of challenges or temptations. Influences an individual’s ability to initiate and maintain behavior change. III. Application of the Transtheoretical Model A. Assessing Readiness for Change The TTM can be used to assess an individual’s current stage of change and their readiness to engage in a specific behaviour change. This information can guide the development of tailored interventions and support strategies. B. Designing Behavior Change Interventions The TTM can inform the design of interventions that target the specific needs and challenges of individuals at different stages of change. Interventions can focus on enhancing the processes of change, decisional balance, and self- efficacy. C. Evaluating Behavior Change Outcomes The TTM can be used to evaluate the effectiveness of behaviour change interventions by assessing changes in an individual’s stage of change over time. This can provide insights into the mechanisms of behavior change and the factors that facilitate or hinder the process. IV. Strengths and Limitations of the Transtheoretical Model A. Strengths Provides a comprehensive framework for understanding the process of behaviour change. Emphasizes the importance of individual readiness and tailoring interventions to specific stages of change. Integrates cognitive, affective, and behavioural aspects of change. B. Limitations Oversimplification of the behaviour change process, which may be more complex and nonlinear. Difficulty in accurately assessing an individual’s stage of change and the transitions between stages. Lack of consistent empirical support for the model’s predictive ability across all behaviours and populations. V. Conclusion The Transtheoretical Model offers a valuable framework for understanding and facilitating behavior change. Its application in health promotion and disease prevention interventions has been widespread and has contributed to the understanding of behavior change processes. Continued research and integration with other theoretical models may further enhance the models explanatory power and practical applications. Social Cognitive Theory (SCT) Developed by Albert Bandura. Emphasizes the role of observational learning, social influence, and self-efficacy in behaviour change. Highlights the interaction between personal factors, environmental factors, and behaviour. I. Introduction to Social Cognitive Theory A. Definition and Overview Social Cognitive Theory (SCT) is a widely-used theory that explains human behaviour in terms of the dynamic and reciprocal interaction between personal, behavioural, and environmental factors. It was developed by Albert Bandura, a renowned psychologist, and has been extensively applied in various domains, including health behaviour, education, and organizational studies. B. Historical Background SCT evolved from the earlier Social Learning Theory, which emphasized the importance of observational learning and modelling. Bandura’s work in the 1970s and 1980s expanded the theory to include a more comprehensive understanding of human agency and the role of cognitive processes in behaviour. II. Key Constructs of Social Cognitive Theory A. Reciprocal Determinism The idea that personal, behavioural, and environmental factors interact and influence each other in a bidirectional manner.  This reciprocal interaction shapes an individual’s behavior and their ability to self-regulate. B. Observational Learning The process by which individuals learn new behaviours by observing the actions and consequences of others. Observational learning is facilitated by attention, retention, motor reproduction, and motivational processes. C. Self-Efficacy An individual’s belief in their own ability to successfully perform a specific behaviour or task. Self-efficacy influences an individual’s choice of activities, effort, and persistence in the face of challenges. D. Outcome Expectations An individual’s anticipation of the likely consequences of their actions. Outcome expectations can be physical, social, or self-evaluative, and they influence an individual’s motivation and behaviour. E. Goals and Incentives Goals provide direction and motivation for behaviour change. Incentives, both intrinsic and extrinsic, can shape an individual's goals and influence their behaviour. F. Self-Regulation The ability to control and manage ones own thoughts, emotions, and behaviours to achieve desired goals. Self-regulation involves self-monitoring, self-evaluation, and self-reinforcement. III. Applications of Social Cognitive Theory A. Health Behavior Promotion SCT has been extensively applied in the development and implementation of health behaviour change interventions, such as those addressing physical activity, nutrition, and disease management. The theory’s emphasis on self-efficacy, outcome expectations, and self-regulation has informed the design of effective behaviour change strategies. B. Educational and Learning Contexts SCT has been used to understand and enhance learning processes in educational settings, such as the role of observational learning, self-efficacy, and goal-setting. The theory has informed the design of instructional methods and the development of educational technologies. C. Organizational and Workplace Behavior SCT has been applied to understand and improve employee motivation, job performance, and organizational effectiveness. The theory’s focus on social learning, self-efficacy, and self-regulation has informed the design of training and development programs. D. Community-Based Interventions SCT has been used to develop and evaluate community-based programs aimed at promoting positive social change and addressing complex societal issues. The theory’s emphasis on the reciprocal interaction between individuals and their environment has informed the design of multilevel interventions. IV. Strengths and Limitations of Social Cognitive Theory A. Strengths Provides a comprehensive framework for understanding and predicting human behavior. Emphasizes the importance of cognitive processes and the role of social and environmental factors in shaping behaviour. Offers practical strategies for behaviour change and intervention design. B. Limitations Complexity of the theory, which can make it challenging to operationalize and test empirically. Difficulty in accounting for the influence of contextual and cultural factors on behaviour. Potential oversimplification of the dynamic and multifaceted nature of human behaviour. V. Conclusion Social Cognitive Theory offers a rich and influential perspective on human behaviour, highlighting the interplay of personal, behavioural, and environmental factors. The theory’s applications in various domains, including health, education, and organizational studies, have demonstrated its versatility and practical value. Ongoing research and integration with other theoretical frameworks can further enhance the explanatory power and applicability of Social Cognitive Theory. Social Ecological Model (SEM) Focuses on the complex interplay between individual, interpersonal, organizational, community, and societal factors that influence health behaviors. Emphasizes the importance of creating supportive environments for behaviour change. I. Introduction to the Social Ecological Model A. Definition and Overview The Social Ecological Model (SEM) is a framework for understanding the multiple levels of influence that shape human behavior and health outcomes. It was developed by Urie Bronfenbrenner and has been widely used in public health, psychology, and other social science disciplines. B. Key Principles Recognizes the interdependence between individuals and their social and physical environments. Emphasizes the importance of considering multiple levels of influence on behavior and health. Acknowledges the dynamic and reciprocal interactions between these different levels. II. Levels of the Social Ecological Model A. Individual Level Factors related to the individual, such as knowledge, attitudes, beliefs, and skills. Includes personal characteristics, behaviors, and developmental history. B. Interpersonal Level Factors related to the individual’s immediate social network, such as family, friends, and peers. Includes social support, social norms, and interpersonal relationships. C. Organizational Level Factors related to the organizations or institutions the individual is affiliated with, such as schools, workplaces, and healthcare systems. Includes policies, practices, and the organizational climate or culture. D. Community Level Factors related to the broader community and social environment, such as neighborhood characteristics, community resources, and social cohesion. Includes the physical and social environment in which individuals and organizations are embedded. E. Policy Level Factors related to local, state, and national laws, regulations, and policies. Includes the political, economic, and social policies that can influence individual and community health. III. Applications of the Social Ecological Model A. Health Promotion and Disease Prevention Designing multi-level interventions that target individual, interpersonal, organizational, community, and policy factors. Addressing the complex and interrelated determinants of health behaviours and outcomes. B. Violence and Injury Prevention Understanding the multilevel factors that contribute to violence and injury, such as individual, family, community, and societal influences. Developing comprehensive prevention strategies that address the various levels of the SEM. C. Environmental and Sustainability Issues Examining the interactions between individuals, their social and physical environments, and broader policy and systemic factors. Informing the design of sustainable development and environmental conservation initiatives. D. Educational and Organizational Settings Applying the SEM to understand and address challenges in educational and workplace environments. Developing comprehensive strategies to promote positive outcomes, such as academic achievement or employee well-being. IV. Strengths and Limitations of the Social Ecological Model A. Strengths Provides a comprehensive framework for understanding the multiple levels of influence on behaviour and health. Encourages the development of multilevel interventions that address the complex and interrelated determinants of health and social issues. Emphasizes the importance of considering the broader social, environmental, and policy context in which individuals and communities are embedded. B. Limitations Complexity of the model, which can make it challenging to fully operationalize and measure all the relevant factors. Difficulty in establishing clear causal pathways and attributing outcomes to specific levels of the model. Potential for oversimplification or neglect of the dynamic and context-specific nature of the interactions between levels. V. Conclusion  The Social Ecological Model offers a valuable and comprehensive framework for understanding and addressing complex social and health-related issues. Its emphasis on the multilevel and reciprocal nature of human behavior and health has informed the design of effective interventions and policies in various domains. Continued research and practical applications of the SEM can further enhance our understanding of the complex and interconnected factors that shape individual and community well-being. Theory of Planned Behavior (TPB) An extension of the Theory of Reasoned Action, developed by Icek Ajzen. Considers the influence of perceived behavioral control in addition to attitudes and subjective norms on behavioral intentions and actual behavior. I. Introduction to the Theory of Planned Behavior A. Definition and Overview The Theory of Planned Behavior (TPB) is a social-cognitive model developed by Icek Ajzen to explain and predict human behaviour. It is an extension of the Theory of Reasoned Action, which focuses on the role of attitudes and subjective norms in shaping behavioural intentions. B. Key Principles Behaviour is primarily determined by an individual’s intention to perform that behaviour. Intention is influenced by three main factors: attitude, subjective norm, and perceived behavioural control. Perceived behavioural control can also directly influence behaviour, in addition to its indirect effect through intention. II. Components of the Theory of Planned Behavior A. Attitude An individual’s overall evaluation or appraisal of the behaviour, whether it is favourable or unfavourable. Influenced by the individual’s beliefs about the outcomes or consequences of performing the behaviour. B. Subjective Norm The perceived social pressure to perform or not perform the behaviour, based on the individual’s beliefs about what important others think they should do. Reflects the influence of the individual’s social network and cultural norms. C. Perceived Behavioral Control The individual’s perception of their ability to perform the behaviour, based on their beliefs about the presence of factors that may facilitate or hinder the behaviour. Includes both internal factors (e.g., skills, knowledge) and external factors (e.g., availability of resources, barriers). D. Behavioral Intention The individual’s motivation or willingness to exert effort to perform the behaviour. Serves as the immediate antecedent of behaviour, mediating the effects of attitude, subjective norm, and perceived behavioural control. E. Behavior  The observable action or response that the individual performs. Directly influenced by the individual’s intention, as well as their perceived behavioural control. III. Applications of the Theory of Planned Behavior A. Health Behaviors Understanding and predicting a wide range of health-related behaviours, such as physical activity, healthy eating, and preventive healthcare utilization. Informing the design of behaviour change interventions targeting individual, social, and environmental factors. B. Environmental Behaviors Explaining and promoting environmentally responsible behaviours, such as recycling, energy conservation, and sustainable transportation. Identifying the cognitive and social factors that influence environmental decision-making and actions. C. Consumer Behaviors Predicting and explaining consumer behaviours, such as purchasing decisions, brand loyalty, and product adoption. Informing marketing and advertising strategies that target the determinants of consumer intentions and behaviours. D. Organizational and Workplace Behaviors Understanding and improving employee behaviours, such as job performance, organizational citizenship, and safety compliance. Developing HR policies and training programs that address the attitudinal, normative, and control-related factors influencing workplace behaviours. IV. Strengths and Limitations of the Theory of Planned Behavior A. Strengths Provides a well-validated and widely-used framework for understanding and predicting human behaviour. Emphasizes the importance of cognitive and social factors in shaping behavioural intentions and actions. Allows for the identification of specific determinants that can be targeted in behaviour change interventions. B. Limitations Focuses primarily on individual-level factors and may neglect the influence of broader environmental and contextual factors. Assumes that behaviour is primarily driven by rational decision-making, which may not always be the case. Difficulty in accurately measuring and predicting certain types of behaviours, particularly those that are habitual or impulsive. V. Conclusion The Theory of Planned Behavior offers a comprehensive and influential framework for understanding and predicting human behaviour. Its emphasis on the cognitive and social determinants of behaviour has led to numerous applications in various domains, including health, environment, and consumer research.  Continued research and practical applications of the TPB can contribute to the development of more effective behaviour change interventions and policies. Application of Theoretical Frameworks Theoretical frameworks in health promotion can be applied to a wide range of health issues, such as smoking cessation, physical activity promotion, and healthy eating initiatives. These frameworks help in developing targeted interventions based on a deep understanding of the factors influencing health behaviors. I. Introduction A.
