Applied Behaviour Analysis

 

  • ABA is the design, implementation, and evaluation of environmental changes to produce socially significant improvement in human behaviour.
  • ABA includes the use of direct observation, measurement, and functional analysis of the relations between environment and behaviour.
  • ABA uses changes in environmental events, including antecedent stimuli and consequences, to produce practical and significant changes in behaviour.
  • These relevant environmental events are usually identified through a variety of specialized assessment methods.
  • ABA is based on the fact that an individual’s behaviour is determined by past and current environmental events in conjunction with organic variables such as their genetic endowment and ongoing physiological variables.
  • ABA focuses on treating behavioural difficulties by changing the individual’s environment rather than focusing on variables that are, at least presently, beyond our direct access.
  • The successful remediation of core deficits of ASD, and the development or restoration of abilities, documented in hundreds of peer-reviewed studies published over the past 50 years has made ABA the standard of care for the treatment of ASD.

The duties of a BCBA

 

  • Describe specific levels of behaviour at baseline when establishing treatment goals.
  • Focus on establishing small practical units of behaviour which build towards larger, more significant changes in functioning related to improved health and levels of independence.
  • Collect, quantify, and analyse, direct observational data on behavioural targets during treatment and follow-up to maximise and maintain progress towards treatment goals.
  • Place an emphasis on understanding the current function and future value (or importance) of behaviour(s) targeted for treatment.
  • Design, establish, and manage the treatment environment(s) in order to minimise problem behaviour(s) and maximise rate of improvement.
  • Use carefully constructed, individualised and detailed behaviour analytic treatment plans which utilizes reinforcement and other behaviour analytic principles as opposed to the use of methods or techniques which lack consensus about their effectiveness based on evidence in peer-reviewed publications.
  • Place an emphasis on ongoing and frequent direct assessment, analysis, and adjustments to the treatment plan (by the Behaviour Analyst) based on client progress as determined by observations and objective data analysis.
  • Use of treatment protocols that are implemented repeatedly, frequently, and consistently across environments until the client can function independently in multiple situations.
  • Provide direct support and training of family members and other involved professionals to promote optimal functioning and promote generalisation and maintenance of behavioural improvements.
