Understanding The Antecedent Behaviour Consequence Model
The antecedent behaviour consequence (ABC) model is a tool that may help individuals examine a behaviour to better understand its key components, including the event or activity that precedes it and the consequences that follow.
By gaining this information, one may attempt to decrease the likelihood of engaging in unwanted behaviour. In addition, the model can act as a point of inspiration for formulating a new plan of action. To learn more about how behaviour works, it may be helpful to review the advantages and limitations of this model and how you might use it to make changes in your life.
What is the ABC model?
In the ABC model, each letter stands for a critical component of a particular behaviour, including the following principles:
• Antecedent
• Behaviour
• Consequence
Antecedent
The antecedent, which means “coming before,” can be any event or environmental factor that occurs before a behaviour, prompting that behaviour. Examples may include exposure to certain activities, people, times of day, topics of conversation, or locations. Gathering this information can help you understand what may be prompting the behaviour, which can be helpful if you want to make a change.
Behaviour
Behaviour is a word to describe one’s actions and repeated habits. In this model, it is an action one tries to understand and potentially change. Examples of such behaviours could be screaming, using unhealthy substances, ignoring one’s emotions, or buying items online to cope with stress.
Consequence
The “consequence” is an event or symptom that occurs after the behaviour in response to that behaviour. For example, if yelling is the behaviour, the consequence might be that their partner leaves the room. This consequence may reinforce a behaviour or modify it.
Examples of the ABC model
Changes to antecedents and consequences in a classroom may modify a child’s behaviour. For example, if a child struggles to participate in a class (behaviour), teachers and parents may modify the antecedents and consequences slightly to make a difference. If the teacher realises that a child participates more when they are reminded to raise their hand to answer a question (antecedent) and that the student responds well to praise (consequence), the teacher may more frequently encourage students to raise their hands (altered antecedent), while offering ample positive feedback after a student answers the question (altered consequence).
In adulthood and other settings, the same concepts can apply. For example, perhaps an individual wants to stop eating chips after dinner (behaviour). In examining their behaviour, they might notice that the easiest snack to reach in the cupboard every night is the chips (antecedent). They might try to remove the chips from the cupboard to alter their behaviour and replace them with a healthier option (altered antecedent). A person can also adjust consequences by adding certain rewards or coordinating with others to receive positive feedback.
Advantages and limitations of the ABC model
The ABC model is just one theory of behavioural psychology. Some people support this model, while others may prefer another option. Below are a few advantages and limitations to consider.
Advantages
Some people may find the ABC model a simple tool to offer insight into otherwise confusing behaviours. In addition, it can be used in various settings and situations. You can try using it to evaluate your behaviour and attempt a change or to understand someone else’s behaviour. Additionally, the ABC model can assist professionals when creating a hypothesis for why a problematic behaviour occurs and how to correct or change it.
Limitations
One disadvantage of the ABC model may be that it can take time, patience, and trial and error. Occasionally, patterns in antecedents and consequences can be unclear or could lead you to draw an incorrect conclusion. While the ABC model can offer insight into a wide range of behaviours, sometimes behaviour is too complicated to assess on your own. In this case, it can be beneficial to consult with a professional. An expert may also be able to analyse the ABC charts you’ve created and identify a pattern.
The ABC model may also not apply to every situation. Although behavioural modification can be helpful for some people, those with complex traumatic pasts may struggle to respond well to behavioural modification, as other factors can go into their behaviour, such as long-term beliefs caused by trauma or a lack of validation and support. Controlling the nervous system before applying behavioural methods may be most effective in these cases.
Other ways to make behavioural changes
Changing how you act can be difficult if you’ve been engaging in certain behaviours for a prolonged period. Below are other ways to make the behavioural change process straightforward.
Understand that change can take time
It can be natural to want change to happen immediately when struggling with a behavioural pattern.
Give yourself positive consequences
Using the ABC model as a guide, you might consider incorporating clear “consequences” that motivate you to change a particular behaviour. These could be positive consequences or rewards for completing a positive behaviour or healthy negative consequences for completing an unwanted behaviour.
For example, you could try a sticker chart to motivate yourself. Although these tools are often used for children, adults can also use them. After you get a certain number of stickers for practicing a desired behaviour, you can reward yourself with something that motivates you. If you practice an undesired behaviour, you can remove one of the stickers toward your goal. You could also make it so you only gain a reward if you practice the desired behaviour every day of the week or for a certain amount of time.
