Overview of ABA and Discrete Trial Instruction

• Laura is growing more confident as an RBT, curious about how job demands vary by learner, service location, and intervention type.

• Expanding Potentials ABA Inc. is a key provider of ABA services, offering diverse options for therapy.

• New staff typically start with discrete trial instruction (DTI) in a clinic before transitioning to other methods and locations.

Importance of Discrete Trial Training

• Discrete Trial Training (DTT): Revolutionized autism treatment, demonstrating significant gains in post-treatment studies.

• Lovas Study: Showed children with autism could join kindergarten with peers after intensive DTT; these gains persisted.

• Established DTT as the standard with a recommended minimum of 25 hours per week.

• By 2014, recognized as a reimbursed treatment for autism under US Center for Medicare and Medicaid Services.

• From Feb 2010 to Feb 2017, there was a drastic increase in the demand for BCBAs and BCaBAs, signaling a similar rise for RBTs since their credential was introduced later.

Role of RBTs

• RBTs provide crucial support in delivering DTT and other ABA interventions, impacting intervention success.

• Must adhere to specific standards for fidelity in ABA strategies due to rising demand and their significant role in therapy.

Session Preparation for Discrete Trials

• Preparation begins prior to the first cue in a discrete trial session.

• Components of a Discrete Trial:

  • Discriminative Stimulus (SD): For example, "Show me your mouth."

  • Learner's Response: E.g., learner touches mouth, does not give spoon.

  • Consequence: Reinforcement and feedback, e.g., "You got it. Great."

• Multiple trials are conducted in set time frames, with intensity being key to success. Oversaturation can lead to diminishing returns, necessitating breaks.

Preparing the Environment

• Minimizing Distractions: Containerizing materials helps cut distractions.

• Knowing the Plan: RBTs should review goals and ask clarifying questions in advance.

• Equipping the Area: All materials should be organized and accessible to facilitate quick trial delivery.

Pairing Yourself as a Reinforcer

• Pairing is essential to foster compliance; it involves associating the technician with enjoyable experiences and reinforcement items.

• Effective pairing includes:

  • Reinforcer assessment to identify what the learner enjoys.

  • Engaging in fun activities and play.

  • Avoiding taking items from learners but encouraging them to ask for them to reinforce positive behavior.

• Successful pairing leads learners to look forward to sessions rather than avoid them.

Conducting Discrete Trials

• Ideal DTI session starts with positive interaction; should be clear and quick between SD delivery and learner response (within 3 seconds).

• Maintain session momentum to maximize reinforcement opportunities.

• Monitor and manage learner engagement, ensuring breaks as needed, depending on age and developmental stage.

• Transitioning back to work after breaks should be smooth; reinforce positive return to task.

Concluding a Session

• End the session with reinforcement and provide feedback to caregivers or supervisors.

• Reflect on the session's effectiveness and identify areas for improvement.

Variations in Service Delivery

Home-based Services

• Advantages: Incorporates family routines and frequent reinforcement.

• Requires clear communication with families regarding expectations.

Center-based Services

• Becoming more common due to increased availability of ABA services.

• Advantages: Better control of environment, materials, and supervision, leading to lower distraction levels and higher consistency.

School and Daycare Services

• Challenges exist in maintaining intensity due to environmental distractions.

• Effective collaboration among staff is crucial to implement discrete trials within educational routines.
