Relationship Development Intervention (RDI) is an intervention approach designed to address the social and communication challenges often experienced by individuals with autism spectrum disorders (ASD). It focuses on improving the ability to form and maintain meaningful relationships by targeting core deficits in social understanding and interaction.


  • Guided Participation: RDI emphasizes the importance of guided participation, where a trained guide (often a parent or therapist) helps the individual with ASD navigate social situations and interactions.

  • Dynamic Intelligence: It aims to develop what RDI terms “dynamic intelligence,” which refers to the ability to think flexibly, adaptively, and in real-time during social interactions.

  • Gradual Progression: The intervention is structured to progress gradually, starting with foundational skills such as joint attention and emotional regulation, and advancing to more complex social skills like perspective-taking and empathy.

  • Parent Involvement: Parents are actively involved in RDI, receiving training to become effective guides in their child’s social development. This approach encourages ongoing support and practice in natural settings.

  • Individualized Approach: RDI recognizes that each individual with ASD has unique strengths and challenges, so interventions are tailored to meet specific needs and abilities.

  • Long-Term Goals: The ultimate goal of Relationship Development Intervention is to enable individuals with ASD to build meaningful relationships, navigate social situations more effectively, and ultimately lead fulfilling lives within their communities.

Relationship Development Intervention (RDI) is primarily designed for individuals who are diagnosed with autism spectrum disorders (ASD). It is intended for:

  1. Children and Adolescents with ASD: RDI is commonly used with children and adolescents who have been diagnosed with autism spectrum disorders. It addresses their specific social and communication challenges in order to improve their ability to form and maintain relationships.

  2. Individuals with Social Communication Difficulties: RDI may also be beneficial for individuals who struggle with social communication difficulties, even if they do not have a formal diagnosis of ASD. This could include those with other developmental or communication disorders where social skills development is a priority.

  3. Families and Caregivers: RDI involves active participation from parents and caregivers who are trained to support the individual’s social development. Therefore, it is also for families who are committed to actively participating in their child’s therapeutic process.

  4. Individuals Needing Support with Dynamic Intelligence: RDI focuses on enhancing “dynamic intelligence,” which refers to the ability to adaptively navigate social interactions and understand social nuances. Thus, it is suitable for individuals who need support in developing these skills.

Relationship Development Intervention (RDI) was developed by Dr. Steven Gutstein, a clinical psychologist specializing in autism spectrum disorders (ASD), and his colleagues. The development of RDI began in the late 1990s as Dr. Gutstein sought to address the core deficits in social understanding and interaction commonly observed in individuals with ASD.

  • Clinical Practice: Dr. Gutstein’s clinical observations and interactions with individuals with ASD led him to recognize the need for an intervention that specifically targeted social and relationship challenges.

  • Research and Theory: RDI is grounded in developmental psychology, cognitive science, and theories of dynamic intelligence. It draws on principles of neurodevelopment to guide its approach to improving social skills and adaptive behavior.

  • Parent Involvement: The role of parents as active participants in the therapeutic process is a fundamental aspect of RDI. Dr. Gutstein emphasized the importance of parents being trained to act as “guides” in their child’s social development, providing ongoing support and opportunities for practice in natural settings.

  • Evolution and Practice: Over time, RDI has evolved based on clinical experience, feedback from families, and advances in understanding autism and related conditions. It continues to be refined and adapted to meet the needs of diverse individuals with ASD and other social communication difficulties.

The core idea behind Relationship Development Intervention (RDI) is to empower individuals with autism spectrum disorders (ASD) to develop meaningful and reciprocal relationships by addressing their specific challenges in social communication and interaction.

Relationship Development Intervention (RDI) involves a structured and systematic approach to improving social and relational skills in individuals with autism spectrum disorders (ASD). Here are the key components and activities typically involved in RDI:

  1. Assessment and Goal Setting: The intervention begins with an assessment to identify the specific social and communication challenges of the individual with ASD. Goals are then set based on this assessment, focusing on areas such as joint attention, emotional regulation, perspective-taking, and social problem-solving.

  2. Guided Participation: Central to RDI is the concept of guided participation, where a trained guide (often a parent or therapist) works closely with the individual with ASD. The guide supports the individual in learning and practicing social skills in real-life situations. This may involve structured activities, role-playing, and modeling appropriate social behaviors.

  3. Skill Building and Practice: RDI aims to build foundational social skills gradually. Activities are designed to encourage the individual to engage in reciprocal interactions, understand non-verbal cues, take turns in conversation, and develop empathy. Skills are practiced in various settings to promote generalization and application in different contexts.

  4. Feedback and Reflection: Throughout the intervention process, feedback is provided to the individual to help them understand their strengths and areas for improvement in social interactions. Reflection on social experiences and discussions about feelings and perspectives are also key components to enhance self-awareness and social learning.

  5. Family Involvement: RDI places a strong emphasis on involving family members, particularly parents, in the intervention process. Parents are trained to become effective guides for their child’s social development. They learn strategies to support their child’s progress, reinforce skills at home, and facilitate social interactions in everyday settings.

  6. Support for Dynamic Intelligence: RDI focuses on developing “dynamic intelligence,” which involves the ability to adaptively respond to social challenges and navigate complex social situations. Activities are designed to promote flexible thinking, problem-solving, and learning from social experiences.

  7. Longitudinal and Individualized Approach: The intervention is typically long-term and individualized, recognizing that progress in social skills varies among individuals with ASD. The pace and focus of intervention are adjusted based on the individual’s strengths, needs, and developmental stage.

Parent education, training, support, and involvement are integral components of Relationship Development Intervention (RDI). Here’s how each aspect contributes to the effectiveness of RDI:

  1. Education: Parents undergo thorough education about autism spectrum disorders (ASD), the specific challenges their child faces in social communication and interaction, and the principles of RDI. This education helps parents understand the rationale behind the intervention strategies and prepares them to play an active role in their child’s development.

  2. Training: Parents receive training on how to implement RDI techniques and strategies in everyday situations. This training typically includes practical skills such as how to engage their child in meaningful social interactions, how to provide constructive feedback, and how to create opportunities for their child to practice and generalize social skills learned during RDI sessions.

  3. Support: Continuous support is provided to parents throughout the RDI process. This support can come from RDI practitioners, other parents going through similar experiences, or support groups specifically for families of individuals with ASD. Having a supportive network helps parents navigate challenges, celebrate successes, and stay motivated throughout the intervention.

  4. Involvement: Parents are actively involved in all stages of RDI. They collaborate with RDI practitioners to set goals for their child, participate in RDI sessions alongside their child, and reinforce skills learned during sessions in daily routines. This involvement ensures that RDI strategies are consistently applied across different environments, promoting generalization of skills.

  5. Empowerment: RDI aims to empower parents as primary agents of change in their child’s social development. By equipping parents with knowledge, skills, and support, RDI enables them to effectively support their child’s growth, foster positive relationships, and advocate for their child’s needs within the community and educational settings.

Cost considerations for Relationship Development Intervention (RDI) can vary based on several factors:

  • Professional Fees: The cost of RDI sessions typically includes fees for trained RDI practitioners or therapists who work directly with the individual with ASD and their family. These fees can vary depending on the practitioner’s expertise, location, and the duration of each session.

  • Assessment and Planning: Initial assessments to identify the specific needs and goals of the individual with ASD may incur additional costs. This assessment helps tailor the RDI program to the individual’s strengths and challenges.

  • Training for Parents: Some RDI programs include training sessions for parents to learn and implement RDI techniques at home. These training sessions may be included in the overall cost or charged separately.

  • Supplementary Materials: Depending on the program, there may be costs associated with supplementary materials such as books, manuals, or online resources that support the implementation of RDI strategies.

  • Duration and Frequency: The total cost of RDI can also depend on the recommended duration and frequency of sessions. Longer-term interventions or more frequent sessions may incur higher costs.

  • Insurance Coverage: Check whether RDI services are covered by health insurance policies. Coverage for autism-related therapies can vary widely depending on insurance providers and regional regulations. Some insurance plans may cover a portion or all of RDI costs if it is deemed medically necessary.

  • Financial Assistance Programs: Some families may qualify for financial assistance programs or grants that can help offset the costs of RDI. Nonprofit organizations or foundations dedicated to autism support may also offer funding or scholarships for therapeutic interventions.
