Co-Occurring Mental Illness and Behavioral Support Needs in Adults with Intellectual and Developmental Disabilities

Area of Science:

• Public Health
• Disability Studies
• Mental Health Research

Background:

• Individuals with intellectual and developmental disabilities (IDD) experience higher rates of mental health conditions and behavioral support needs.
• Community providers often do not adequately address the mental health care requirements for individuals with IDD.
• There is a critical gap in understanding the prevalence and influencing factors of co-occurring conditions within this population.

Purpose of the Study:

• To examine the rates of co-occurring mental health and behavioral conditions in adults with IDD utilizing state-funded services in Virginia.
• To identify individual- and system-level factors associated with these co-occurring conditions.
• To inform improved support systems for community-dwelling adults with IDD and co-occurring mental health needs.

Main Methods:

• Analysis of data from two datasets representing a sample of adults with IDD who use state-funded services.
• Categorization of mental health and behavioral conditions into four distinct groups.
• Statistical examination of differences in individual and system-level factors between those with and without co-occurring conditions.

Main Results:

• A high prevalence of co-occurring mental health and behavioral conditions was observed in the studied sample.
• Significant associations were found between specific disability factors and system-level characteristics with the presence of diagnosed mental health conditions or behavioral support needs.
• Patterns of diagnosis and treatment varied, indicating potential disparities in care.

Conclusions:

• The high rates of co-occurring conditions underscore the need for integrated care models for individuals with IDD.
• Addressing both individual and system-level factors is crucial for effective mental health support.
• Further research and policy development are necessary to enhance community-based care for adults with IDD and co-occurring mental health conditions.
