Table 4.

One-way MANOVA—subscales measuring attitudes toward genetic testing by age of participants.

Age	Subscales
	Benefits		Awareness		Outcomes
	M	SD	M	SD	M	SD
21 years and younger	1.62a	0.54	1.60a,b	0.97	2.29	0.53
22 to 50	1.28a	0.40	1.16a	0.35	2.05	0.53
Over 50 years	1.45a	0.49	1.18b	0.45	2.25	0.57

MANOVA F ratio: F [6,316] = 3.90, P = 0.001, d = 0.07 (based on Wilk's lambda).

Between subjects: benefits: F [2,160] = 5.19, P = 0.007, d = 0.06.

Awareness F [2,160] = 6.49, P = 0.002, d = 0.08.

Outcomes F [2,160] = 3.01, P = 0.052, d = 0.04.

Note: Lower scores indicate more positive perceptions of attitudes toward genetic testing.

Means in a column sharing subscripts are significantly different.

Twenty granddaughters were less than 12 years of age and did not complete the attitudes toward genetic testing survey.
