Formatted Abstract/Summary
Aim: Individuals with ID who exhibit challenging behaviour are often diagnosed with a mental illness (MI). Prevalence rates of MI vary from study to study. There has been discussion regarding this variability and its sources. Diagnosis of MI can be conceptualized as a perceptual task where the clinician reports whether the stimulus (MI) is present or absent. The theory of signal detection suggests that the variability in diagnosis results from difficulties in identifying the signal (the MI) from the noise (typical fluctuations in human behaviour). Using this model, there are four potential outcomes: MI is present and is diagnosed (accurate diagnosis); is present but is not identified (missed diagnosis); is not present but is diagnosed (false positive); and is not present and is not diagnosed. The theory further posits that decision-making is affected by the consequences of the decision.

Conclusion: The prevalence of MI among individuals with ID is still not known at this time.
