Background This study investigated the completion rates, scores and factors associated with non-completion and low scores on physical capability tests in a health survey administered to adults with intellectual disabilities. Method Assessment comprised body mass index (BMI), the Short Physical Performance Battery (SPPB), the timed up-and-go (TUG) test, the one-legged stance (OLS) test; and gross motor, communication and behavioural functioning tests. Results The completion rates among 93 participants (aged 17–78) were 46% for the SPPB, 42% for the TUG, and 31% for the OLS. More severe intellectual disability (OR = 3.12, p < .001) and lower BMI (OR = 0.859, p = .001) were related to test non-completion. The SPPB scores were below the reference values from the general population. Lower scores were associated with older age, motor disabilities and intellectual disability severity. Conclusions Including physical capability tests in health surveys among adults with intellectual disabilities is important to monitor functional status and guide prevention strategies.
