Regression results for predicting Time 2 PEFR from intimate and non-intimate Time 1 social roles in full HRS sample (N = 4028)

	Variables Evaluated Individually in Separate Models ^a				Variables Evaluated Simultaneously in Single Model
	β	b	p-value	CI₉₅ for b	β	b	p-value	CI₉₅ for b
Intimate Social Roles ^b	0.025	5.304	< .001	[1.412, 9.196]	0.020	4.225	.034	[0.313, 8.138]
Non-Intimate Social Roles ^c	0.046	5.868	< .001	[3.433, 8.302]	0.044	5.545	< .001	[3.093, 7.996]
					Addition of SI variables: ΔR² = 0.002, p < .001

Note: HRS = Health and Retirement Study; PEFR = peak expiratory flow rate

All models adjusted for Time 1 PEFR, age, gender, ethnicity, education, height, and weight

Intimate social roles included family, friends, parent, and spouse

Non-intimate social roles included club, employee, religious service attendee, and volunteer
