On completion of this tutorial, you will be able to:
- Discuss the differences between aggressive, non-assertive and assertive behaviour
- List the highlights of assertive behaviour
Assertive/Responsive Model

Assertion refers to behaviour that involves:
- Standing up for your own rights in such a way that you do not violate another person's rights
- Expressing your needs, wants, opinions, feelings and beliefs in direct, honest and appropriate ways
So, assertiveness is based on beliefs that in any situation:
- You have needs to be met
- The other people have needs to be met
- You have rights, so do others
- You have something to contribute, so do others
The aim of assertion is to satisfy the needs and wants of both parties in the situation (known as 'Win/Win').
Non-assertion refers to behaviour which involves the following:
- Failing to stand up for your rights or doing so in such a way that others can easily disregard them
- Expressing your needs, wants, opinions, feelings and beliefs in apologetic, diffident or self-effacing ways
- Failing to express honestly your needs, wants, opinions, feelings and beliefs
Non-assertion is based upon the beliefs that in any situation:
- The other person's needs and wants are more important than your own
- The other person has rights but you do not
- You have little or nothing to contribute; the other person has a great deal to contribute
The aim of non-assertion is to avoid conflict and to please others.
Aggression refers to behaviour that consists of the following:
- Standing up for your own rights, but doing so in such a way that you violate the rights of other people
- Ignoring or dismissing the needs, wants, opinions, feelings or beliefs of others
- Expressing your own needs, wants and opinions (which may be honest or dishonest) in inappropriate ways
Aggressive behaviour is based on the belief that:
- Your own needs, wants and opinions are more important than other people's
- You have rights but other people do not
- You have something to contribute; others have little or nothing to contribute
The aim of aggression is to win, if necessary, at the expense of others.
Example of the three different behaviours
Situation:
Taking an unsatisfactory letter back to the person who produced it
Assertion:
'John, I'd like you to re-do this letter as there are several mistakes in it.'
Non-assertion:
You find an excuse not to take the letter back, or you say: 'I know it's um .... any chance at all you could find a spare minute to um just change one or two small things on this letter for me.'
Aggression:
'I don't know how you've got the nerve to give me this sort of stuff for signing. It's full of mistakes.’
