DISC Bulletin Board: Questions/Answers
I encourage DISC Users to contact me via email with any questions they might have regarding the DISC administration or interpretation. Your questions and my responses will be placed on a "Bulletin Board" for all DISC Users to review.
Question dated May 29, 1999:
"I just finished screening a 13-year-old girl. In the Fine Motor column, the child's age equivalent is 13-14 months when I plot her score. So why is the "Interpretation", based on the child's age, "Possible Delay"? Is she on track for her age?"
I receive this question quite often. What you have to remember is that the "Approximate Age Equivalent Form" can only provide an "approximation" of the child's developmental "age in months". The DISC is only a screening tool, not a diagnostic tool, so, as the DISC manual states on p. 45, the "Age Equivalent Tables" should be used with caution.
Usually, a child who shows an "approximate age level" with a delay of more than 1/3 of his/her chronological age (i.e. 12-month-delay in a 36-month-old child), will have an interpretive category of "Probably Delay". As well, usually a child who shows an "approximate age level" that falls close to his/her chronological age, will have an interpretive category of "Average". However, this is not always the case. Age equivalents are far less accurate than the percentile values that are used to determine the "Interpretive category". It is best to use the Interpretive category as the most accurate method of interpreting DISC results.
