Individual items can be scored by assigning point values to correspond to response categories. For items with a range‚ a midpoint value can also be assigned. Incidence rates for items 1‚ 2‚ 5‚ 6‚ 7 and 8‚ and standard errors for these estimates are calculated as follows:
Incidence Rate = Σ(i=1 to n) PiCi
Standard Error = √ΣCi2(Var(Pi)
P = the proportion of subjects
i = (1‚2‚3….n) levels of the variable of interest
C = frequency of behavior
Incidence Rate = the proportion of subjects with the behavior of interest (Pi) multiplied by the frequency of that behavior (Ci)‚ or use a midpoint if there is a range.
Standard Error = the square root of the sum of the frequency of the behavior squared (Ci2) multiplied by the variance of each proportion (Var(Pi)).
Example: Incidence Rate of Weapon Carrying Among Hispanic Females
i = 1‚2‚3‚4 (1 day‚ 2.5 days‚ 4.5 days‚ 6+ days)
j = 1‚2‚3 (White‚ Black‚ Hispanic)
k = 1‚2 (Female‚ Male)
For Hispanic females (j=3‚k=1) the incidence rate can be designated as IRjk or IR31 and calculated as follows:
IR31 = Σ(i=1 to 4) Pi31Ci.
