Logistic regression predicting blood donor status

Donor status Donor status Donor status
Step 1 R2 = 0·16, Step χ2 = 48·36 (P < 0·001) R2 = 0·16, Step χ2 = 48·38 (P < 0·001)
 Intentions 0·06** 0·06**
 Attitudes 0·10** 0·10**
 Subjective norm 0·03 0·03
 PBC 0·01 0·01
Step 2 R2 = 0·08, Step χ2 = 23·67 (P < 0·001) R2 = 0·20, Step χ2 = 9·93 (P = 0·07)
Impure altruism 0·10*** 0·06*
Self-regarding −0·01 −0·002
Kinship −0·04 −0·03
Reluctant altruism 0·08** 0·07*
Egalitarian warm glow −0·02 −0·05

*P < 0·05, **P = < 0·01, ***P =< 0·001.

N = 410. Coefficients are unstandardized coefficients values.

Blood donor status (0 = non-donor; 1 = donor).
