This study investigated value congruence effects on organizational commitme
nt and job satisfaction. We used the competing values framework to measure
values, and response-surface methodology employing polynomial regression eq
uations to investigate congruence effects. Our sample, 1,358 hospital emplo
yees, made judgments about their personal preferences for the four competin
g value sets-internal process, open systems, rational goal, and human relat
ions. They also:rated how much the same values were operating in the organi
zation. We predicted that organizational commitment and job satisfaction wo
uld be maximized when a 'match' or 'congruence' occurred between the two co
mponent value measures. We evaluated congruence effects using the following
criteria: (1) the proportion of variance explained by the overall equation
was significant; (2) the quadratic and interaction terms were significant
individually and as a set, and their signs were in the right direction; (3)
the implied constraints were valid; and (4) no higher-order terms beyond t
hose indicated by the model were significant. The results indicated that al
though quadratic and interaction components were present in all eight model
s, they were weak in their support for congruence. The study's findings sug
gested that congruence effects were relatively unimportant compared to main
effects in explaining variance in organizational commitment and job satisf
action, at least in the large organization we investigated in this study. C
