Implementing DTT at Home: Tips for Parents

Understanding Discrete Trial Training

Discrete Trial Training (DTT) is a widely used teaching method in Applied Behavior Analysis (ABA) therapy, particularly for children with autism. Developed in the 1970s by Dr. Ivar Lovaas, DTT aims to break down activities into fundamental components to teach important skills through repetition and reinforcement. By using this structured approach, DTT provides clear and systematic instruction to help learners acquire new skills and build a solid foundation for further learning.

What is DTT?

DTT is a teaching technique that takes a skill a child needs to learn and breaks it down into smaller components taught in a graduated manner. It involves presenting short, uncomplicated trials to match the child's attention span and providing clear instructions to promote understanding. Each trial consists of three main components: the antecedent (stimulus or instruction), the response from the child, and the consequence (reward or reinforcement) [2].

The goal of DTT is to help children acquire and generalize a wide range of skills, including communication, social, and academic skills. By systematically teaching these skills in a structured and repetitive manner, DTT promotes skill development and learning in children with autism.

Importance of DTT

DTT plays a crucial role in helping children with autism improve various aspects of their development. Here are some key reasons why DTT is considered important:

1. Attention and Motivation: DTT is designed to capture and maintain a child's attention by breaking down tasks into manageable and engaging components. The use of rewards and reinforcements during DTT sessions helps motivate the child to actively participate and learn [1].
2. Communication Skills: By using clear and unambiguous instructions, DTT helps children with autism develop and improve their communication skills. The structured nature of DTT provides a supportive environment for teaching language and promoting expressive and receptive communication abilities [3].
3. Generalization Abilities: DTT aims to enhance the generalization of skills by introducing variations in instructions and settings. This helps children transfer learned skills from one context to another, enabling them to apply their knowledge and abilities in different situations [1].

DTT provides a structured and effective approach to teaching children with autism, allowing them to acquire new skills and reach their full potential. By focusing on individualized learning goals and tailoring instruction to the specific needs of each child, DTT offers a valuable tool for parents and therapists in supporting the development of children with autism.

Components of Discrete Trial Training

Discrete Trial Training (DTT) involves breaking down skills into discrete steps and teaching each step systematically. The structured format of DTT consists of several key components that contribute to its effectiveness in teaching new skills and promoting learning. These components include the antecedent and prompt, response and consequence, and the inter-trial interval.

Antecedent and Prompt

In DTT, the antecedent is the specific instruction or question provided to the learner, signaling the beginning of a trial. The antecedent sets the stage for the desired response. It is important to provide clear and concise instructions or cues to ensure that the learner understands what is expected of them.

To support the learner's understanding and facilitate correct responding, prompts are often used in DTT. Prompts can take different forms, such as verbal prompts, physical prompts, or visual cues, depending on the learner's needs and abilities. The prompt is gradually faded over time as the learner becomes more independent in their response.

Response and Consequence

The learner's response is a crucial component of DTT. Once the learner receives the antecedent and prompt, they are expected to provide a specific response. The response can be a correct or incorrect one, and it is important to provide immediate feedback to the learner based on the accuracy of their response.

In DTT, the consequence for a correct response includes positive reinforcement, such as verbal praise, edibles, or tokens. This reinforcement helps to strengthen the association between the correct response and the desired outcome, motivating the learner to continue making progress. In contrast, an incorrect response is simply corrected without a reward or punishment.

Inter-Trial Interval

The inter-trial interval (ITI) is the period between the end of one trial and the beginning of the next. It is essential to maintain a consistent and appropriate ITI in DTT to ensure efficient and effective instruction. The ITI should be kept relatively short, typically no more than five seconds in most cases, to maintain the learner's engagement and momentum.

During the ITI, the instructor prepares for the next trial, sets up any necessary materials, and provides brief positive feedback or redirection if needed. The consistent timing of the ITI helps to create a structured and predictable learning environment, promoting the learner's focus and attention.

By understanding and implementing these key components of DTT, parents can effectively utilize this teaching technique at home. The structured nature of DTT, with its clear antecedents, prompts, responses, consequences, and inter-trial intervals, provides a solid framework for teaching a wide range of skills to children with autism spectrum disorder (ASD) and other developmental disabilities.

Benefits of Discrete Trial Training

Discrete Trial Training (DTT) offers numerous benefits for individuals, particularly children with autism spectrum disorder (ASD) and other developmental disabilities. By breaking down activities into short, uncomplicated trials, DTT caters to the attention span of learners and provides them with an effective learning environment. Let's explore some of the key benefits of DTT:

Attention and Motivation

One of the primary advantages of DTT is its ability to improve attention and motivation in learners. By breaking down skills into smaller components and providing consistent prompts and reinforcement, DTT captures the attention of individuals and maintains their engagement throughout the learning process. This focused attention promotes effective learning and skill acquisition.

Communication Skills

DTT plays a crucial role in enhancing communication skills in individuals with ASD. Through its basic and unambiguous instructions, DTT provides learners with clear and structured language models, facilitating the acquisition of language and communication skills. By systematically teaching language components, such as vocabulary, sentence structure, and conversation skills, DTT supports the development of effective communication abilities.

Generalization Abilities

Generalization, or the ability to apply learned skills to different settings and situations, is an important aspect of learning. DTT incorporates variations in instructions over time, teaching learners to apply acquired skills in a generalized manner. This promotes the transfer of skills from the training environment to real-life situations, allowing individuals to apply what they have learned in different contexts.

It's important to note that DTT is particularly effective for individuals with ASD and other developmental disabilities, as it provides a highly structured and predictable learning environment. This structured approach helps learners with autism acquire new skills and build a solid foundation for further learning.

By focusing on attention and motivation, improving communication skills, and promoting generalization abilities, DTT offers significant benefits for individuals undergoing this form of training. The systematic and structured nature of DTT contributes to its effectiveness in promoting skill acquisition and supporting individuals in reaching their full potential.

Effectiveness of Parent-Implemented DTT

When it comes to implementing Discrete Trial Training (DTT) at home, parents play a vital role in providing structured and effective intervention for their children with autism. With the advent of telehealth training, parents now have access to resources and support to successfully implement DTT in the comfort of their own homes.

Telehealth Training

A study conducted with three parent participants of children diagnosed with autism spectrum disorder (ASD) demonstrated that telehealth training allowed parents to effectively implement DTT in home settings. The study showed that telehealth delivery of training was successful in increasing performance levels across all three parents, resulting in high efficacy in the acquisition of DTT skills [4].

Through telehealth training, parents receive remote guidance and support from professionals who specialize in DTT. This allows parents to learn and practice the key components of DTT, such as antecedent and prompt, response and consequence, and inter-trial interval. By mastering these components, parents can effectively implement DTT strategies and techniques at home, promoting skill acquisition and development in their children.

Results and Efficacy

The results of the study indicated that telehealth training had a significant impact on both parent and child performance. As parents' implementation of DTT became more accurate, there was a corresponding increase in child skill acquisition targets. The mean percentage of correct steps in DTT increased from 49% at baseline to 99% during the maintenance phase. This demonstrates the effectiveness of telehealth training in improving parent implementation of DTT and subsequently enhancing child skill acquisition [4].

Moreover, the study showed that telehealth delivery of training was successful in increasing performance levels across all three parents. Child skill acquisition targets also increased above baseline levels following parent telehealth training in DTT. The mean percentage of correct responding for child participants increased from 26% at baseline to 80% during the maintenance phase. These findings highlight the positive impact of parent-implemented DTT facilitated through telehealth training.

The effective implementation of DTT by parents at home, with the support of telehealth training, allows for greater dissemination of behavior analytic instructional methods and service provision. This is particularly beneficial for typically underserved populations, as it provides access to evidence-based interventions that can support the development and progress of children with autism.

By embracing telehealth training and actively participating in their child's DTT program, parents can play a crucial role in promoting skill acquisition, communication, and generalization abilities in their children with autism. The effectiveness and success of parent-implemented DTT highlight the importance of parental involvement and the positive outcomes that can be achieved through this collaborative approach.
