title: [Screening for intellectual disability among adults].
abstract: BACKGROUND
  Instigation of proper measures in case of intellectual disability is often conditioned by a diagnosis. Our aim was to assess whether the Hayes Ability Screening Index (HASI) is a suitable screening instrument for intellectual disability among adults.
  
  
  METHODS
  The article is based on three former studies aimed at validating HASI for use among patients referred for neuropsychological examination, prison inmates and psychiatric inpatients in community mental health centres.
  
  
  RESULTS
  The sample consisted of 264 persons. The HASI correlated with the more comprehensive scales of assessing intellectual functioning (Wechsler tests) (r = 0.73, p < 0.001). With a cut-off value of 85, HASI had a sensitivity of 0.97 and a specificity of 0.61 in relation to an IQ < 70.
  
  
  CONCLUSIONS
  HASI is associated with few false negatives, but a large number of false positives. This implies that an intellectual disability is concluded in too many cases; a positive screening should be followed up with a more thorough assessment.
