  1. Behavioral Change Models for Healthcare Workers Objective:  Explore theoretical models that may prove useful for changing hand hygiene behavior among healthcare workers

  2. Classification of Theoretical Models • Current models that help to explain human behavior can be classified according to their level of influence: 1) Intrapersonal level – based on cognitive variables such as knowledge, motivation, intention, perception of threat, outcome expectancy, perceived behavioral control and social pressure – which shape individual behavior • - Health Belief Model, Stages of Change Model, • Theory of Reasoned Action

  3. Classification of Theoretical Models Con’t 2) Interpersonal level – people learn and behave not only from their own experiences but also by observing other’s actions and through role modeling - Social Cognitive Theory, Theory of Planned Behavior 3) Community and Social levels – human behavior both influences and is influenced by the social environment - Diffusion of Innovation Theory, Kanter’s Structural Theory of Power Organization, Theory of Ecological Perspective

  4. Intrapersonal Models • Health Belief Model(Hochbaum et al., 1950s) •  Assumes that individuals make rational choices when presented with the pros and cons of change BehavioralChange is a product of an individual’s health beliefs which are based on the perceived susceptibility, perceived severity, perceived benefits, and perceived barriers • Change is undertaken when the pros or benefits of the new behavior outweigh the cons or barriers to the behavior

  5. Intrapersonal Models Con’t • Stages of Change Model(Prochaska et al., 1970s) •  Assumes that change occurs gradually, that is, individuals are often at different levels of motivation, and should be approached with behavior interventions that match their level of readiness to change (importance + confidence) • Individuals move back and forth through 6 stages before lasting change is finally achieved: Precontemplation  Contemplation  Preparation Action Maintenance  Termination

  6. Intrapersonal Models Con’t • Theory of Reasoned Action(Fishbein & Ajzen, 1975) •  Proposes that behavior change is a function of one’s intention to change • Behavioral intention is a function of attitudes toward the behavior and subjective norms - Attitudes, defined as favorable or unfavorable opinions, arise from a combination of beliefs about its consequences and evaluations of those consequences - Subjective Normsare based on normative beliefs, defined as perceptions of the views of other individuals; and on motivation to comply, defined as the strength of the individual’s desire to gain approval of these groups

  7. Interpersonal Models • Social Cognitive Theory (Bandura, 1970s) •  Assumes that an individual’s behavior both influences and is influenced by their cognitive processes and their social/physical environment • Proposes that behavior change is determined by three types of expectancies: • - Situation-Outcome Expectanciesare expectations • that relate to the behavior • - Outcome Expectanciesrefer to the value of the • behavior change • - Self-Efficacyrefers to the belief that one has the • ability to make the change

  8. Interpersonal Models Con’t • Theory of Planned Behavior (Ajzen, 1988) • Explains aspects of behavior not under individual control and assumes that immediate cause of a behavior is intention to perform the behavior • Intention is predicted by three variables: attitudes toward the behavior; subjective norms; and perceived behavioral control – defined as a person’s perception of the ease or difficulty in performing the target behavior  These three variables are in turn predicted by: behavioral beliefs(consequences of behavior); normative beliefs(expectations of others); and control beliefs(presence of obstacles and/or opportunities that may facilitate or impede performance of the behavior)

  9. Community & Social Models • Diffusion of Innovation Theory (Rogers, 1983) • Rogers defines diffusion as the process by which an innovation is communicated through certain channels over time among members of a social system • Proposes that certain characteristics of the innovation itself may facilitate its adoption • Other factors influencing its acceptance include promotion by influential role models, the degree of complexity of the change, compatibility with existing values and needs, and the ability to test and modify the new procedure before adopting it

  10. Community & Social Models Con’t • Kanter’s Structural Theory of Power Organization (Kanter, 1977) • States that power in organization is derived from structural conditions, not personal characteristics or socializing effects  Proposes that three organization structures that influence work effectiveness: power(derived from formal and informal sources); opportunity(chances to increase knowledge and skills); and proportions(social composition of people in approximately the same situation)

  11. Community & Social Models Con’t • Theory of Ecological Perspective • (Brofenbrenner et al., 1979) • Assumes that human behavior is affected by and affecting multiple ecological levels of influence: 1. Individual - personal characteristics such as age, gender, family, etc. are responsible for human behavior which are influenced by cognitive factors 2. Interpersonal - immediate social settings as family, peer groups, work manager influence – are important sources of social control 3. Community – work factors including institutional policies/regulations, and administrative environment 4. Societal - cultural and social norms, mass media, political influences

  12. Application of Theoretical Models to Hand Hygiene To be successful, we need to develop a hand hygiene program which effectively integrates all levels of influence in such a way as to effect and maintain the desired behavior change Intrapersonal level: increase HCWs awareness and knowledge of the importance of hand hygiene Interpersonal level: obtain visible commitment of senior administration, and increase perception of hand hygiene as a priority issue Community & Social levels: increase availability and accessibility of appropriate hand hygiene products, and increase awareness and access to hand hygiene programs
