Recently, attention has been focused on dizziness and vertigo in children. The purpose of the present investigation was to develop a metric to measure dizziness disability/handicap outcome for use with patients who are between 4 and 16 years of age. 40 items comprising the alpha version of the DHI-P  (e.g. Does your child’s problem make it difficult for him/her to play) were administered to 86 caregivers.  Their responses to each item were limited to “yes” (scored as 4 points), “sometimes” (scored as 2 points) or “no” (scored as zero points).   Cronbach’s alpha showed that item-total coefficients of this initial data set enabled us to eliminate 15 noncontributing items reducing the scale to 25 items (i.e. beta version). 

We administered the beta version of the DHI-P to 56 primary caregivers of dizzy children (mean patient age 10 years, SD 3 years).  The analysis showed a single factor (eigenvalue of 8.30) explained 33 % of the total item variance.  Item-total correlations showed that 4 items demonstrated item-total correlations less than .40 and they were deleted.  The final version of the DHI-P has 21 items and a maximum score of 84
