Notes. WHP1 = Women’s Health Project-1 (Carey et al., 1997); WHP2 = Women’s Health Project-2 (Carey et al., 2000); HIP = Health Improvement Project (Carey et al., 2002); r18–45 = Correlation between the long and short versions of the HIV-KQ; rTT = test-retest correlations; T1 = baseline; T2 = post-intervention; T3 = follow-up; Numbers in parentheses indicate limit criterion values for alpha and rTT (observed values should equal or exceed limit criterion values if the brief version of a test is to be acceptable according to Spearman-Brown formula).
