Comparision of participant positive predictive value estimates between experience grouping variables.

Variable	Measure	Status		Mann-Whitney U Test
		Yes	No	U	z-value	p-value^*

Previous Mammogram Status	Median score–before (IQR)	50.0 (25)	35.0 (30)	455	–.854	.393
	Median change score (IQR)	–20.0 (40)	–18.5 (39)	476	–.532	.594
Knowing a friend or family member with breast cancer	Median score–before (IQR)	40.0 (30)	50.0 (26)	525.5	–.391	.696
	Median change score (IQR)	–18.0 (38)	–24.0 (33)	490	–.862	.389

The criteria for significance was set at p < .05, with Bonferroni correction. No tests reached significance.
