Prior research supports a positive relationship between job and family
satisfaction. Although this relationship has been taken as support fo
r the spillover hypothesis, it is also consistent with an alternate hy
pothesis that has received little attention. The congruence hypothesis
states that job and family satisfaction are positively related becaus
e they share a common cause or causes. Thus, the distinction between t
he spillover and congruence hypotheses reflects the broader distinctio
n between causal and noncausal (i.e., spurious) covariation. The goal
of this study was to determine which hypothesis best reflects the rela
tionship between job and family satisfaction. Data were obtained throu
gh household interviews with a random sample of 631 individuals. Struc
tural equation modeling techniques were used to estimate simultaneousl
y a reciprocal relationship between job and family satisfaction and a
noncausal correlation between their disturbance terms. Results support
ed the congruence hypothesis, indicating that the relationship between
job and family satisfaction is characterized best as noncausal.
