The Developmental, Individual-differences, Relationship-based (DIR) model is a developmental model for assessing and understanding any child's strengths and weaknesses. It has become particularly effective at identifying the unique developmental profiles and developing programs for children experiencing developmental delays due to autism, autism spectrum disorders, or other developmental disorders. This Model was developed by Dr. Stanley Greenspan and first outlined in 1979 in his book Intelligence and Adaptation. Evidence for the efficacy of DIR/Floortime includes results from randomized controlled trials of DIR/Floortime and the DIR/Floortime-based P.L.A.Y. Project; because of various limitations in these studies, the existing evidence is deemed to "weakly support" the efficacy of Floortime.
The Developmental, Individual-difference, Relationship-based (DIR) model is the formal name for a new, comprehensive, individualized approach to assess, understand, and treat children who have developmental delays (including, but not limited to: Autism Spectrum Disorder). Focusing on the building blocks of healthy development, this approach is also referred to as the "Floortime" or "DIRFloortime" approach. However, Floortime is actually a strategy within the DIR model that emphasizes the creation of emotionally meaningful learning exchanges that encourage developmental abilities.
The goal of treatment within the DIR model is to build foundations for healthy development rather than to work only on the surface of symptoms and behaviors. Here, children learn to master critical abilities that may have been missed along their developmental track. For example, Autism Spectrum Disorder (ASD) has three core/primary problems: (1) establishing closeness, (2) using emerging words or symbols with emotional intent, and (3) exchanging emotional gestures in a continuous way. Secondary symptoms (perseveration, sensory-processing problems, etc.) may also exist. Thus, treatment options are based on particular underlying assumptions. The DIR model is based on the assumption that the core developmental foundations for thinking, relating, and communicating can be favorably influenced by work with children's emotions and their effects.
The DIR model was developed to tailor to each child and to involve families much more intensively than approaches have in the past. Through the DIR model, cognition, language, and social and emotional skills are learned through relationships that involve emotionally meaningful exchanges. Likewise, the model views children as being individuals who are very different and who vary in their underlying sensory processing and motor capacities. As such, all areas of child development are interconnected and work together beneficially.
Floortime Model Approach
Floortime is a developmental intervention involving meeting a child at his or her current developmental level, and challenging them to move up the hierarchy of milestones outlined in the DIR Model. Floortime is child-focused—the parent or therapist follows the child's lead, with playful positive attention while tuning into the child's interests. Once the child connects with the adult specific techniques are used to challenge and entice the child to move up the developmental ladder. Dr. Stanley Greenspan and his wife Nancy described this intervention for the first time their 1989 book, The Essential Partnership. Floortime has since made its way into homes, clinics, schools and hospitals as an effective intervention for various types of learning and developmental challenges.
The DIR model is based on the idea that due to individual processing differences children with developmental delays, like ASD, do not master the early developmental milestones that are the foundations of learning. DIR outlines six core developmental stages that children with ASD have often missed or not mastered:
- Stage One: Regulation and Interest in the World: Being calm and feeling well enough to attend to a caregiver and surroundings. Have shared attention.
- Stage Two: Engagement and Relating: Interest in another person and in the world, developing a special bond with preferred caregivers. Distinguishing inanimate objects from people.
- Stage Three: Two way intentional communication: Simple back and forth interactions between child and caregiver. Smiles, tickles, anticipatory play.
- Stage Four: Continuous Social Problem solving: Using gestures, interaction, babble to indicate needs, wants, pleasure, upset. Get a caregiver to help with a problem. Using pre-language skills to show intention and become a creative and dynamic problem solver.
- Stage Five: Symbolic Play: Using words, pictures, symbols to communicate an intention, idea. Communicate ideas and thoughts, not just wants and needs.
- Stage Six: Bridging Ideas: This stage is the foundation of logic, reasoning, emotional thinking and a sense of reality.
Most typically developing children have mastered these stages by age 4 years. However, children with ASD struggle with or have missed some of these vital developmental stages. When these foundational abilities are strengthened through the child's lead and through meaningful play with a caregiver, children begin to climb up the developmental ladder.
Structure of the DIR Model and the Floortime Approach
The DIR Model and the Floortime Approach work in two general parts: Assessment and Intervention. Within each of these two categories, there are further steps and strategies.
The initial step for assessment is [Screening]. The creator of the DIR Model, Dr. Stanly Greenspan, developed a measuring tool, the Greenspan Social-Emotional Growth Chart (GSEGC), to aid parents, caregivers and clinicians in this beginning step of assessment. This tool is a basic 35-item questionnaire that evaluates a child according to the social-emotional milestones he or she has met. This preliminary step is a quick method to screen children for risk or diagnosis of Autism Spectrum Disorder (ASD) or Pervasive Developmental Disorder (PDD).
Following the initial screening process is conducting a [Comprehensive Functional Developmental Evaluation]. A child that has been screened with the GSEGC and displays significant developmental delay will then proceed to this step. In this process, a single clinician or clinicians of multiple disciplines (i.e. pediatrics, speech therapy, occupational therapy, psychology, etc.) must spend a significant amount of time observing a child. Specifically, the clinician(s) must be able to characterize how the degree to which a child is able to interact with others as it relates to developmental level.
In the final step of Assessment an [Individual Developmental Profile] is created based on the Comprehensive Functional Developmental Evaluation performed on the child. This profile is made to characterize a child's socio-emotional capacities. Through this profile, the DIR Model is able to tailor its intervention strategies uniquely to each child.
Once the Assessment phase is completed the Intervention period is initiated. There are four different areas that the Floortime Approach aims its interventions: 1) Home 2) Educational Programs 3) Therapies 4) Play Dates.
First, the strategies and exercises laid out in the Home Intervention are of great importance for a child. It involves three core interactions: floortime; semi-structured, problem-solving interactions; and motor, sensory, perpetual-motor, and visual-spatial physical activities.[unreliable medical source?]
|Floortime||Play with child by following his or her lead|
|Semi-structured Problem Solving||Create tasks that build of the child's interests to encourage and nurture his or her problem solving skills|
|Motor, Sensory, and Perceptual-Motor Activities and Visual-Spatial Activities||Engage child in activities that are tailored to his or her unique needs as it relates to motor, sensory, and perceptual-motor and visual-spatial activities|
Second, interventions can also be applied through Educational Programs. Just as in the Home Interventions, the three core interactions are utilized in schools. Instead of primary caregivers carrying out these interactions it will be the responsibility of the teachers, teacher assistants, or peers. As an added efficiency measure, Individualized Educational Plans (IEP) can be collaboratively created and tailored for a child by his or her primary caregivers, teachers, or clinician. The IEP is developed with the purpose of outlining the goals of improvement for a child's specific developmental needs.
Another component of the DIRFloortime Model Intervention is a multi-disciplinary approach through different therapies. According to a child's Individual Developmental Profile, primary caregivers or clinicians can determine what types of therapy will benefit a child based on his or her developmental need. Such therapies can include working with a speech therapist, occupational therapist, clinical psychologist, etc.[unreliable medical source?]
The final intervention component of the DIRFloortime Model is Play Dates. While it is extremely important for a child to develop strong and healthy relationships with his or her primary caregiver(s), it is also essential to encourage play dates with other children. However, this step must be taken when the child is able to securely interact with others and is beginning to build his or her capacity for imitation and problem-solving skills.[unreliable medical source?]
The effectiveness of Floortime was examined in four randomized controlled trials in which the control group receive the usual therapies (e.g., speech therapy, occupational therapy). Because of various methodological limitations, these studies were deemed to provide "weak support" to Floortime as a therapy for autism. Language function in the Floortime groups did not improve beyond what was observed in the controls. No adverse effects of Floortime have been reported.
