An A-B-C analysis is a descriptive assessment that is conducted as an initial part of a complete functional behavior assessment. The goal of this analysis is to. The Antecedent-Behavior-Consequence (ABC) Model is an approach that can be used to help people examine behaviors that want to change, the triggers of. The environment the person is in – social, relationships, Consequences either increase the likelihood of a behaviour Antecedents are typically any prompts.
C gets his jacket and lines up Consequence: C's teacher says "Good Job! His family members give him the toy, D stops screaming. D wants his favorite toy Behavior: D receives the toy and stops screaming In the future D screams for all of his toys. Positive social reinforcement tangible item Function for family members: Negative reinforcement 17 Other Factors To Consider 1.

Time of day 2. Activity 20 What are Functional Behavior Assessments? A FBA is a procedure that is used to help identify what is reinforcing or maintaining the behavior of concern. It involves generating a hypothesis as to why an individual does something. Knowing and understanding the relationship between the Antecedent-Behavior-Consequence contingency allows us to: Knowledge of the Antecedent-Behavior-Consequence relationship provides us with information that can be used to reduce or eliminate problem behaviors by intervening before or after they occur.
The alarm clock ringing is an antecedent for waking up. Hunger pangs in our stomach are typically an antecedent for searching for food. Raindrops falling on us are typically an antecedent for opening our umbrella, or quickly seeking out a drier location. A dry mouth is typically an antecedent for finding something cold to drink. Consequences are actions or events that directly follow the occurrence of a behavior.
Consequences either increase or decrease the probability that the behavior they follow will occur again in the future. A student completes an assignment and the teacher praises the student and gives her a sticker. The praise and sticker are a consequence for task completion, and increase the probability the student will complete additional assignments in the future.
A student fails to complete their daily assignments, and the teacher takes away the students free-time privileges. Taking away free-time privileges is the consequence for not completing assignments. The consequence is meant to increase the probability the student will complete classroom assignments in the future.
A child sees a candy bar in the store and asks his Mother if she might purchase one.
The child begins to cry and tantrum. Mother tries to ignore, but after 5 minutes gives in and buys the child a candy bar. Johnson daughter Shelly returned home two hours past her curfew. Taking away privileges is the consequence for breaking curfew, and increases the probability that Shelly will be home on time in the future. By understanding the ABC relationship, and honing our skills as keen observers of behavior, we can begin to use our knowledge and skills to address common classroom behavior problems before they become critical.
ABC’s of Behavior (Antecedent-Behavior-Consequence)
An ABC Analysis involves carefully observing each occurrence of a problem behavior, and documenting the antecedent condition that preceded the behavior, giving a detailed description of the behavior, and the consequence event that followed the behavior. Once a predictable pattern begins to emerge in our data, we can begin brainstorming ways to intervene.
Based upon the ABC model there are only two possible options with regard to intervening with problem behaviors: Intervene Before the behavior occurs, or intervene After the behavior occurs.
This is the simplest, most effective, and least time consuming method for addressing problem behavior. An ABC Analysis indicates that Jimmy typically shoves his work off onto the floor, curses, and overturns his desk during math seatwork time. Clearly, math seat-work is an antecedent for Jimmy to act out.
By altering the environment though curriculum modifications, extra assistance, slicing back on the quantity of and difficulty level of the task, we can significantly reduce the probability that Jimmy will continue to act out.
This is referred to as Consequence Interventions. Confidence in a hypothesis statement increases when evidence for the function maintaining a behavior shows up across a number of functional assessment tools. Direct observation is especially important since it is less subjective than interview strategies that rely on memory and a person's perceptions.

What are the advantages and disadvantages of the ABC Chart? The ABC Chart allows an observer to record descriptive information about a student in a systematic and organized way. This recording format is easier to use than other observation forms that collect both scatter plot and ABC data such as the Functional Assessment Observation Tool included in this module.
The data gathered provides a lot of descriptive information about the student's behavior and the environment. A major disadvantage for using the ABC Chart is that it can be more difficult to see patterns quickly, and the data may need to be summarized to look for patterns related to antecedents and consequences.
If a student engages in multiple problem behaviors, if there are several antecedents events, or if the student's behavior is being maintained by multiple functions, the ABC Chart may take more time to summarize compared to the Functional Assessment Observation Tool. ABC Chart data is only correlational which means the causal relation cannot be confirmed. Strategies that systematically manipulate environmental antecedents and consequences, referred to as a functional analysis, are often used in research.
However, in many cases, direct observations that include information about behavior, environmental events preceding and following the behavior, and time of occurrence are sufficient to provide confidence in the team's hypothesis statement. When should the ABC Chart be used? The ABC Chart is often completed after initial interviews and record reviews are conducted, but these activities may occur concurrently. Functional assessment interviews can provide information about when and where observation sessions will be conducted.
How do you know when you have collected enough observational data?
- Presentation on theme: "Understanding Behavior"— Presentation transcript:
Each functional assessment is different, just as each student is unique and engages in different types of behavior. Direct observational data should be collected until the team members are confident about the function or functions maintaining a student's behavior. In simple situations, this may occur within sessions. In more complicated cases, direct observation data may be needed across a number of settings and for longer periods.
If your team remains unsure that the hypothesis statement s are accurate, find a professional with a background in applied behavior analysis or positive behavior support who can assist with the functional assessment. This professional may recommend different data collection methods or could assist in conducting a functional analysis.
