Some limitations may include questions being misinterpreted or misunderstood, unawareness or over-reporting of symptoms, and the same symptoms being rated different levels of "obtrusiveness" in daily functioning. Questions of the validity of the test have come up, but studies of over a decade prove it to be promising in the<unk>  process.
