Multivariate tests indicated that the trajectories of husbands and wives did not differ significantly from each other on three out of four measures. On the KMS, however, the difference between husbands' and wives' slopes was marginally significant,
X2( 1, N — 54) = 3.41, p = .06, with wives' slopes being more negative than husbands' slopes. Both parameters of husbands' and wives' trajectories were significantly correlated with each other on all measures. For intercepts, between-spouse correlations ranged from .59 to .81 across measures (all significant at p < .001). For slopes, between-spouse correlations were nearly perfect, ranging from .97 to .98 across measures. Because husbands' and wives' trajectories were estimated within the same model, the HLM program controlled for the nonindependence of husbands and wives' trajectories in all subsequent analyses.
