Attitudes toward Genetic Testing for Hypertension among African American Women and Girls

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.
