There were no significant differences between groups on pre-intervention or post-intervention measures. However, significant within-group improvement was seen on all measures.

b

10 true–false knowledge items included: having family history of CRC increases risk; people with colon polyps are at higher risk; all colon polyps are cancerous; screening decreases death from CRC: office rectal exam is good CRC screening test; only people with CRC symptoms need screening; CRC always causes symptoms; CRC is most curable when caught early through screening; for most people, CRC screening should start at age 50; and people with family history of CRC or polyps should start screening at a younger age than others. Possible range of scores was 0 to 10; alpha = 0.63.

c

Ten attitudinal statements included: I am interested in screening because someone close to me had cancer; I am interested in CRC screening; I am afraid that screening is painful; screening will reduce my mana; screening is embarrassing; CRC is not a problem for Hawaiians; I do not want to know if I have cancer; if I have cancer it will kill me, so there is no point in getting screened; I am not comfortable talking about CRC; and I am not comfortable touching my stool. Items were rated on a 4-point scale from 1 = strongly disagree to 4 = strongly agree. Possible range of scores was 4 to 40; alpha = 0.91.

d

Three items about intention to talk to doctor about screening, participate in screening, and talk to family about screening were rated on a 4-point scale from 1 = strongly disagree to 4 = strongly agree. Possible range of scores was 3 to 12; alpha = 0.91.

e

Three items about confidence in ability to complete FOBT, explain importance of CRC screening to family, and explain FOBT to family were rated on a 4-point scale from 1 = strongly disagree to 4 = strongly agree. Possible range of scores was 3 to 12; alpha = 0.94.
