Introduction: The aim of this systematic review was to synthe-
size the literature on the correlates and risk factors of anxiety
among adults with ID.
Methods: Following the PRISMA guidelines, a systematic search
of peer-reviewed literature was conducted across six major
electronic databases. From an initial screening of 844 records,
13 studies were included for full-text review. Factors associated
with anxiety were categorized utilizing the biopsychosocial
model. Methodological quality was evaluated.
Results: Correlates of anxiety were identified at all levels of the
biopsychosocial model, including psychological or psychiatric
diagnoses, level of ID, gender, chronic health conditions, stress-
ful life events, and social interactions. Modifiable correlates were
discussed as potential targets for designing anxiety interven-
tions for adults with ID.
Conclusion: Despite the increased recognition of the mental
health needs of individuals with ID in recent years, this review
highlighted a dearth of research investigating the risk factors of
anxiety among this population.
