Univariate correlation of intention with significant ( ) determinants, all determinants.
(1) Background information: age, gender, partner (married, living together, no partner), kids (yes, no), and educational level (finished with a certificate).
(2) Determinants measured with one or two items: profession or faith, perceived importance of faith, perceived importance of family (ties), perceived importance of adapting to the Dutch culture, perceived importance of maintaining own culture, perceived importance of health, perceived responsibility for own health, perceived importance of doctor's advice, perceived importance of fate/destiny, and perceived importance of a higher power/God which influences health.
(3) Multiple item scales within scenario 1 (“Imagine you participated in HbP carrier screening and it shows you are a carrier for HbP”): knowledge about HbP and carrier (screening) (5 items), anticipated positive feelings (2 items, Cronbach's alpha = 0.49), anticipated negative feelings (3 items, alpha = 0.52), attitudinal beliefs about HbP carrier screening (10 items, alpha = 0.73), perceived social norm of HbP carrier screening (7 items, alpha = 0.88), self-efficacy (trust in own abilities to participate in HbP carrier screening; 2 items, alpha = 0.65), and risk perception of being a carrier or having a child with HbP (4 items, alpha = 0.81).
2Backwards multiple regression analysis (Pin = 0.05 en Pout = 0.055) with the significant determinants of the univariate analysis. Adjusted = 0.27; only the significant determinants in the model are displayed.
