Model results of intervention effects on mean emotions

	DV: Negative emotion (6-month) w/ Moderator		DV: Positive Emotion (6-month) w/ Moderator
	Est.	95% CI	Est.	95% CI
Intercept	1.42***	(1.36, 1.49)	2.35***	(2.28, 2.42)
Intervention	−.02	(−0.17, 0.12)	.08	(−0.01,0.17)
Baseline of DV	72***	(0.56, 0.89)	.68***	(0.57, 0.78)

Intervention × PTSD	−.43***	(−0.59, −0.27)	−.42**	(−0.72, −0.12)
Residual variance	.04**	(0.02, 0.06)	.13***	(0.11,0.15)
Intercept variance	.00	(−0.04, 0.04)	.00	(−0.002, 0.003)
Model R2 (within cluster or organization)	.49***		.67***
Model R2 (between clusters or organizations)	.76		.95

Note. DV = Dependent variable. Models controlled for baseline levels of outcome variable. All estimates listed represent unstandardized values. For the intervention variable, 1 = intervention condition and 0 = control condition. Intercept variances represent variability in the outcome variables due to the clustering of employees in the randomized organizations. All continuous predictors and the PTSD predictor are grand-mean centred. For the centred PTSD screening variable, −.13 = negative and .87 = positive PTSD screen. Ns = 92.
