B45: Behaviour Modification Chapter 13: Understanding Problem Behaviours through Functional Assessment Before taking action to eliminateincrease a behaviour one must identify the variables before treating the problem variable through functional assessment. Functional assessment- process of generating info on the events preceding and following the behaviour in an attempt to determine which antecedents and consequences are reliably associated with the occurrence of the behaviour. Includes indirect assessment through interviews, questionnaires, observation etc. DEFINING FUNCTIONAL ASSESSMENT One basic principle of behaviour analysis is that behaviour is lawful; its occurrence is controlled by environmental variables; that is, it is a function of environmental variables. It is the process of gathering info about the antecedents and consequences that are functionally related to the occurrence of a problem behaviour It may include the time and place of behaviour, people present when the behaviour occurs, any environmental events immediately preceding the behaviour and the frequency of the behaviour. o This info on the 3 term contingency will help to identify the antecedents that have stimulus control over the behaviour and the reinforcing consequences that maintain the behaviour. o Also provides other types of info such as: motivational variables, stimuli that may function as reinforces for the person, history of previous treatments and outcomes etc. Here is a list of categories of the information you can find from a functional assessment: Problem behaviour, antecedents, consequences, alternative behaviours(info on desired beh, motivational variables (things that may influence the effectiveness of reipotential reinforcersinfo on environments that may function as reinforc, and previous interventions FUNCIONS OF PROBLEM BEHAVIOUR Four broad classes of reinforcing consequences of problem behaviour: 1) Social Positive Reinforcement When a positively reinforcing consequence is delivered by another person after the target behaviour. May involve attention, access to activities or tangibles provided Ex. Anna received attention from her mother as a reinforcer for her problem behaviour.
