Gave money to a panhandler. , if items 5 and 6 had positive loadings, then item 4 would have a negative loading). This would complicate the creation of a component-based scale: with items 5 and 6, higher scores indicate greater giving whereas with item 4, lower scores indicate greater giving. You would not want to sum these three items as they are presently coded. First, it will be necessary to reverse item 4. Notice how this is done in the following program (assume that the data have already been input in a SAS dataset named D1): data D2; set D1; ❶ V4 = 8 - V4; GIVING HELPING = (V4 + V5 + V6); = (V1 + V2 + V3); proc corr DATA=D2; var GIVING HELPING; run; Line ❶ of the preceding program created a new, recoded version of variable V4.
