title: Normative data for the digit-letter substitution task in school children.
abstract: OBJECTIVE
  To establish the norms for the substitution task, a measure of psychomotor performance.
  
  
  METHODS
  Eight hundred and forty three school students were selected in the present study aged between 9-16 years (mean age = 12.14; SD = 1.77). Subjects were assessed one at a time for Digit-Letter Substitution Task (DLST).
  
  
  RESULTS
  Both age and sex influenced performance on the DLST; therefore, correction scores were obtained on the basis of these factors.
  
  
  CONCLUSIONS
  The availability of the Indian normative data for the DLST will allow wider application of this test in clinical practice.
