Stability and influence model estimates for wives’ and husbands’ drinks per occasion across waves

Parameter	Wives’ drinks per occasion		Husbands’ drinks per occasion
	b	SE	b	SE
Step 1
Intercept	0.57***	0.02	1.09***	0.03
Baseline marital duration	-0.003*	0.001	-0.01***	0.002
Step 2
Actor lagged drinks per occasion	0.12***	0.01	0.17***	0.01
Partner lagged drinks per occasion	0.02***	0.01	0.08***	0.02
Pseudo R2	0.05		0.06
Δ -2 log likelihood	1,094.39***

Notes: Coefficients are presented from the full model (Step 2). Pseudo R² is the proportion of explained variance in the random effect of the full model relative to the covariate-only model (Step 1). Change in -2 log likelihood for Step 2 (57,007.35) is based on comparison with Step 1 (58,101.74). N = 1,257 married couples.
