Functional behavioural analysis (FBA) might be a helpful way to look beyond the problem behaviour or substance use and understand human behaviour on a different level. FBA is a widely accepted method in child psychology in which difficult situations are analysed and categorised into antecedents (A), behaviour (B), and consequences (C). In other words, what happened beforehand, what did the person do, and what were the effects of that behaviour. This way, you can identify potentially triggering situations, reflect upon your own behaviour, and guide the child towards more helpful ways of regulating.
Now you might argue that ABC analyses already have a place in Relapse Prevention, and you would be absolutely right. Trigger recognition plays a large role in this type of therapy. What is interesting, however, is that this model goes one step further by linking it to a function. According to behavioural psychologists, human behaviour serves one (or more) of the following functions: Escape, Attention, Tangibles, and Sensory. Below you will find an overview of what these functions entail, linked to examples of how this might look like for someone with substance use disorder. The behaviours used in this example might not always be directly linked to alcohol or drug use but might be correlated.
Escape: Behaviours to try to avoid, delay or end something unpleasant (e.g. taking a drink before giving a presentation to calm the nerves, not picking up the phone when someone calls).
Attention: Behaviours that desire a response from someone. In substance use disorders, this can take the form of manipulation (e.g. lying about events to create an excuse for drinking that is being validated by others, drinking to fit in and being liked by others).
Tangibles: Behaviours to try to gain something physical (e.g. begging for money (to buy alcohol or drugs), engaging in casual encounters at the bar to get free drinks, engaging in (high-risk) sexual behaviours).
Sensory: Behaviours that make us feel good (about ourselves) or replace discomfort (e.g. drinking to numb or cope with the (mental or physical) pain, getting high).
