Reasoned action model

The reasoned action model1 assumes that most forms of human behaviour are a matter of choice. Thus, the most immediate determinant of any given behaviour is an individual's intention about whether or not to perform that behaviour. This in turn is influenced by the degree to which the person has a positive attitude towards the behaviour, and the degree to which they expect that important others will think that they should perform the behaviour. For example, if someone is told not to do something by someone they respect, they are more likely to act on that warning, according to the reasoned action model.

This model is strongly biased towards changing subjective beliefs, but does not prescribe a particular methodology for doing so.

There are very few evaluations of interventions aiming to alter beliefs and intentions amongst people at risk of HIV infection, despite the strength of association demonstrated between intention and behaviour in such areas as smoking control, alcoholism treatment, contraceptive behaviour and weight loss.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
