Note. Factor Analysis, Eigen values: Factor 1 = 4.54, Factor 2 = 2.15, Factor 3 = 1.65 with Oblimin Rotation; loadings ≥ 0.30 shown in table, total % variance accounted for by 3 factors = 60%. Mean scale scores range from 1 to 4. (R) = Item reverse scored.

^aItem(s) stem = “Most of your close friends think.”

^bItem(s) stem = “Most of your close friends.”

^cCondom items based on both stems and were examined with and without z-transformation which, as expected, had no effect on correlations

^dFirst two items stem = “How many of your close friends are.”; third item stem = “Most of your closest friends think.”
