16. BEHAVIOURAL CONSIDERATIONS<br />
16.1 SOCIAL SCIENCES AND HEALTH BEHAVIOUR<br />
<strong>Hand</strong> <strong>hygiene</strong> behaviour varies significantly among HCWs within the same institution or<br />
unit 485 , thus suggesting that individual features could play a role in determining behaviour.<br />
Social psychology attempts to understand these features, and individual factors such as social<br />
cognitive determinants may provide additional insight on hand <strong>hygiene</strong> behaviour 541,551,552 .<br />
16.1.1 SOCIAL COGNITIVE VARIABLES<br />
Over the last quarter of the 20th century, it was stated that social behaviour could be best<br />
understood as a function of people’s perceptions rather than as a function of real life (objective<br />
facts, etc.) 553 . This assumption gave birth to several models which were based on social<br />
cognitive variables and tried to better understand human behaviour. The determinants that<br />
shape behaviour are acquired through the socialization process and, more importantly, are<br />
susceptible to change – for which reason they are the focus of behavioural models. In other<br />
areas of health-care promotion, the application of social cognitive models in intervention<br />
strategies has regularly resulted in a change towards positive behaviour 553 . Some of the socalled<br />
“social cognitive models” applied to evaluate predictors of health behaviour include:<br />
Health Belief Model (HBM); Health Locus of Control (HLC); Protection Motivation Theory<br />
(PMT); Theory of Planned Behaviour (TPB); and Self-efficacy Model (SEM). The cognitive<br />
variables used in these models are:<br />
• knowledge;<br />
• motivation;<br />
• intention: a person’s readiness to behave in a given way, which is considered to<br />
be the immediate antecedent of behaviour;<br />
• outcome expectancy: an individual’s expectation that a given behaviour can<br />
counteract or increase a threat and how one perceives the threat;<br />
• perception of threat is based on the perceived risk/susceptibility and the perceived<br />
severity of the consequences;<br />
• perceived behavioural control (self-efficacy): the perception that performance of<br />
a given behaviour is within one’s control;<br />
• subjective norm: beliefs about the expectations of an important referent towards<br />
a given behaviour 553,554 ;<br />
• behavioural norm: an individual’s perception of the behaviour of others 555 .<br />
Subjective and behavioural norms represent the perceived social pressure towards<br />
a certain behaviour.<br />
16.1.2 MODELLING HUMAN BEHAVIOUR<br />
Current models and theories that help to explain human behaviour, particularly as they<br />
relate to health education, can be classified on the basis of being directed at the individual<br />
(intrapersonal), interpersonal, or community levels. The social cognitive models mentioned<br />
above deal with intrapersonal and interpersonal determinants of behaviour. Among the community-level<br />
models, the theory of Ecological Perspective (also referred to as the Ecological<br />
Model of Behavioural Change) can successfully result in behavioural change. This theory<br />
is based on two key ideas: (i) behaviour is viewed as being affected by and affecting mul-
