Mediation analysis from social network measures to changes in theoretical mediators to weight change for INSHAPE CLE participants.^a

Predictors/mediators	Dietary knowledge change		Social support change		Self-efficacy change
	β (95% CI)	P value	β (95% CI)	P value	β (95% CI)	P value
Out-degree	–.01 (–.06 to .05)	.83	–.09 (–.32 to .14)	.43	–.29 (–.64 to .06)	.11
In-degree	–.03 (–.37 to .31)	.88	.04 (–.20 to .29)	.73	–.89b (–1.62 to –.16)	.02
Network constraint	1.22 (–1.52 to 3.95)	.38	–1.21 (–3.84 to 1.40)	.36	2.43 (–1.99 to 6.86)	.28

^aIn the analysis, out-degree and in-degree were log-transformed. All models controlled for the outcome before the intervention, the treatment group indicator, age, race, education status, and BMI.
