What is functional analysis?
Functional analysis refers to the process of understanding how thoughts, feelings, and behaviours interact in a person’s life; it aims to identify the triggers or antecedents that precede a particular behaviour and the outcomes or consequences of that behaviour that reinforce it. The fundamental idea is that behaviours cannot be understood in isolation. To understand how a behaviour works or the impact it has (it’s function) you need to understand the context within which the behaviour occurs. Functional analysis emphasises the context and what it accomplishes for the individual, rather than merely their content.
The ABC model of functional analysis
The ABC model of functional analysis is a framework used to understand behaviour by examining its components: Antecedents, Behaviour, and Consequences.
Here’s a breakdown of each element:
1. Antecedents (A)
Definition: These are the events or conditions that occur before a specific behaviour.
Purpose: Identifying antecedents helps to understand what triggers the behaviour. This can include environmental cues, social interactions, or internal states (like feelings or thoughts).
2. Behaviour (B)
Definition: The specific action or response that is being analysed.
Purpose: This is the target behaviour that needs to be understood and potentially modified. It could be anything from aggression to avoidance. It can also include internal behaviours, such as worry or rumination.
3. Consequences (C)
Definition: These are the outcomes or responses that follow the behaviour.
Purpose: Consequences can increase or decrease the likelihood of a behaviour. Positive consequences might include attention or rewards (positive reinforcement), or removing something unpleasant (negative reinforcement) while negative consequences could involve punishment or loss of privileges.

Key components of functional analysis
Functional analysis is a systematic method used to understand the causes and consequences of specific behaviours. The main components of this process are:
- Behaviour identification: Selecting a specific behaviour that needs to be analysed.
- Assessment: Collecting data on the behaviour, including when it occurs, the context, and its triggers and consequences.
- Hypothesis formation: Developing hypotheses about why the behaviour occurs based on the collected data.
- Experimental testing: Conducting experiments to test the hypotheses by modifying antecedents or consequences to see how the behaviour changes.
The ultimate goal of functional analysis is to understand the function of a problematic behaviour to inform interventions that can modify or replace maladaptive behaviours with more adaptive ones.
The applications of functional analysis are wide reaching and can be used across a variety of settings and conditions. Examining behaviours to understand their triggers and consequences can in turn help therapists and other support workers develop effective interventions and support strategies.
How functional analysis can be used with ACT
ACT’s main objective is to increase psychological flexibility and promote meaningful behaviour change through the use of acceptance and mindfulness. By understanding the function of existing unhelpful behaviours, and the consequences that arise, individuals can move towards acceptance and commitment to their values.
- Psychological flexibility: ACT promotes psychological flexibility, encouraging individuals to adapt their responses to situations based on their values rather than being dictated by their internal experiences.
- Acceptance and mindfulness: By recognising the functions of thoughts and feelings, individuals can learn to accept them without judgment, nurturing mindfulness and reduce the struggle against the unwanted experiences or behaviours.
- Self as context: Functional analysis can identify patterns of maladaptive behaviour and highlight how avoidance or control strategies instead lead to psychological distress. ACT helps to develop a broader sense of self that can observe and accept these findings without being overwhelmed by them. Recognising that our thoughts, emotions, and experiences are transient, and that we should make room for them without avoidance or suppression is a key component of moving forward within ACT.
- Values clarification: ACT helps individuals clarify their values, guiding them to take committed actions that align with what truly matters to them, despite the presence of difficult thoughts and emotions. Reminding individuals of the consequences in relation to these values, helps to focus and prioritise behaviours.
