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‚ 3 and 4‚ and standard errors forthese estimates are calculated as follows:
Incidence Rate = Σ(i=1 to n) PiCi
Standard Error = √(ΣCi^2(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 (Ci^2) multiplied by the variance of each proportion (Var(Pi)).
Example: Incidence Rate of Physical Fighting Among White Females
i = 1‚2‚3‚4‚5‚6‚7 (1 time‚ 2.5 times‚ 4.5 times‚ 6.5 times‚ 8.5 times‚ 10.5 times‚ 12+ times)
j = 1‚2‚3 (White‚ Black‚ Hispanic)
k = 1‚2 (Female‚ Male)
For white females (j=1‚k=1) the incidence rate can be designated as IRjk or IR11 and calculated as follows:
IR11 = Σ(i=1 to 7)Pi11Ci
