title: Odor identification testing in children and young adults using the smell wheel.
abstract: OBJECTIVE
  Olfaction is important for nutrition, safety, and quality of life. Detecting smell loss in young children can be difficult, since many children with olfactory deficits do not recognize their problem and may even pretend to smell. The short attention span of some young children precludes testing with longer standardized olfactory tests. Currently there is a dearth of pediatric smell tests. In this study we evaluated the performance of 152 children and young adults on a game-like rotating "Smell Wheel" odor identification test. This forced-choice test, which can be self-administered, was designed to capture the child's imagination and to provide a standardized test measure with odors known to young children using a minimum number of trials.
  
  
  METHODS
  Thirty 4-5-year olds (10 female), 62 6-7-year olds (17 female), 30 10-11-year olds (18 female) and 30 18-19-year olds (15 female) were tested. Analysis of variance was used to assess the influences of sex and age on the test scores.
  
  
  RESULTS
  All participants completed the simple and rapid test protocol. Test performance and age-related changes analogous to those obtained using longer tests were observed. Test scores of participants who self-administered the test were equivalent to those for whom the test was administered by the experimenter.
  
  
  CONCLUSIONS
  Good compliance and olfactory test findings congruent with literature results were obtained using the Smell Wheel, suggesting that this test may be useful in assessing olfactory function in pediatric settings where attentional demands are compromised and test time is limited.
