​What is the DIR® (Developmental, Individual-differences, Relationship-based) model, and why is it an important approach?

Overview

 

The Developmental, Individual-differences, Relationship-based (DIR®) model offers a developmental framework for assessing and supporting individuals with autism and other developmental or mental health challenges. It is a comprehensive approach that uses emotionally meaningful interactions and personalized experiences to foster growth and learning.

​

Created by Drs. Stanley Greenspan and Serena Wieder, the DIR® model was the first to outline the “functional emotional developmental capacities” that form the basis for lifelong learning and relating. It connects these key developmental milestones to the unique biological and neurological differences in how each person processes sensory information. Central to the model is the understanding that relationships are the driving force in nurturing and maximizing development.

​

Many children with special needs face neurobiological differences that make it harder to fully engage in or enjoy early emotional exchanges with their caregivers. Positive, enjoyable, and meaningful parent–child interactions provide the essential foundation for all areas of growth. The DIR® model empowers parents in their natural role as partners in development, supporting progress in areas such as regulation, joint attention, communication and language, motor abilities, cognition, imagination, problem-solving, and social understanding.

​

This approach is truly interdisciplinary, drawing from expertise in pediatric medicine, developmental psychology, education, speech and language, and occupational and physical therapies—making it one of the first fully integrated models for children with autism and other developmental differences.

​

How does DIR® work?

 

 

DIR® starts with helping parents and children connect through enjoyable, developmentally appropriate interactions. The focus is on strengthening the caregiver–child relationship, since this relationship is the foundation for all areas of growth.

​

Professionals trained in the DIR® Model—often from fields such as medicine, psychology, speech and language therapy, occupational and physical therapy, special education, or early intervention—guide this process. Parents are encouraged to practice these strategies with their child throughout the day, both in structured sessions and in everyday routines.

​

The model emphasizes key functional emotional developmental milestones that bring together emotional and intellectual growth. Individualized goals are created for each child, and progress is closely monitored through observation, data collection, and video review. As the child advances, goals and strategies are adapted to match their unique developmental profile. Relationships serve as the primary pathway for learning, engaging, and finding meaning in experiences, making this a flexible and comprehensive approach that evolves as the child matures.

​

Development is not a straight line

​

In a relationship-based approach, every child is understood as having an inner life filled with feelings, desires, and experiences. Just as important, the emotions and perspectives of parents are also taken into account. To truly support a child’s growth, caregivers and professionals need to reflect not only on the complexity of the child’s development and functioning, but also on their own responses and experiences.

​

Because each child and family brings unique differences, best practices must be guided by both developmental theory and extensive clinical experience. Two core principles shape this work:

​

1. Every therapeutic approach must be tailored to the individual characteristics of the child, their family, and the broader systems around them.​

​

    2. Human development is lifelong, and with the right support, individuals can continue to build new 

         skills and progress at any stage.
