Find the Right Path

Psychological Assessments, a well-regarded clinical psychology practice, has made a new and valuable guide available to the community. The latest blog post, “A Complete Guide to Understanding IDD – Part 4: The Four Levels of Support Needed,” explores the various support requirements for individuals with an Intellectual Developmental Disability. This detailed resource is designed to assist families, carers, and service providers in gaining a clearer understanding of the different levels of IDD and their impact on an individual’s daily life. It outlines each of the four levels: Mild, Moderate, Severe, and Profound, with explanations of the corresponding behaviours, communication, and support needed. These insights from the team at Psychological Assessments provide a beneficial starting point for anyone seeking to learn more about Intellectual Developmental Disability Brisbane.

Mild IDD (About 85% of people with IDD)

Understanding the severity of IDD helps determine what type and level of support someone needs. Remember, these aren’t fixed categories – someone’s needs can change over time or in different situations.

What You Might Notice:

Learning: Slower to grasp new academic concepts, may need extra time and support in school
Social: Interactions can seem immature for their age, and may be easily influenced by others
Daily Life: Can handle basic daily activities but needs support with complex tasks like managing finances or major life decisions

Support Needed:

Assistance during major life transitions (starting work, living independently)
Help with complex decision-making
Support to avoid being taken advantage of
Ongoing guidance rather than constant supervision

Real Life Example: Sarah, 25, works at a local café with some job coaching support. She lives in a share house with housemates who help with budgeting and planning. She travels independently on familiar routes but needs support for new places or complex tasks like dealing with government agencies.

Moderate IDD (About 10% of people with IDD)

What You Might Notice:

Learning: Marked delays in learning, academic skills develop slowly, and remain limited
Social: Communication is simpler and more concrete, and needs support in social situations
Daily Life: Requires supervision for many daily tasks, needs repetitive teaching to learn new skills

Support Needed:

Daily supervision and support
Structured learning with lots of repetition
Help with most practical tasks
Support for social interactions and relationships

Real Life Example: Michael, 30, attends a day program where he does simple work tasks. He lives in supported accommodation with 24-hour staff support. He can dress himself and help with basic cooking, but needs prompting and supervision for most activities.

Severe IDD (About 3-4% of people with IDD)

What You Might Notice:

Learning: Very limited understanding, education focuses on basic life skills rather than academics
Social: Limited spoken language, needs significant support for social communication
Daily Life: Needs constant supervision and help with self-care and household tasks

Support Needed:

Constant supervision and care
Supported accommodation
Assistance with all daily living tasks
Communication support (may use pictures, gestures, or assistive technology)

Real Life Example: Emma, 28, lives in a Supported Independent Living accommodation with 24-hour support. She communicates mainly through gestures and a few words. Staff help her with all personal care, meals, and activities. She enjoys music and simple activities but needs constant support and supervision.

Profound IDD (About 1-2% of people with IDD)

What You Might Notice:

Learning: Significant delays affecting all areas, including mobility and communication
Social: Very limited communication, mainly through non-verbal cues, relationships limited to family and familiar carers
Daily Life: Completely dependent on others for all personal care and life tasks

Support Needed:

Complete dependence on carers for all activities
Specialised medical and therapeutic support
Constant supervision and care
Assistive technology for communication and mobility

Real Life Example: James, 35, requires full-time care. He has limited mobility and communicates through facial expressions and body language. Staff provide all personal care, feeding, and medical support. He responds to familiar voices and enjoys sensory experiences like music and gentle touch.
