Testing the Hypotheses
A Pearson correlation was performed to test the
first hypothesis (relationship between user participation
and information quality). Significant positive correlation
between user participation and information quality was
observed (r = 0.319; significance value = 0.027, p-value ≤
0.05), thus lending support for the first hypothesis.
Hypotheses 2 through 4 were tested by using
moderated regression analysis (following Aiken and West
[1]). All variables (except the dependent variable,
information quality) were centered to avoid problems
with multicollinearity [1]. Centering a variable is
accomplished by subtracting its mean off each value of
the variable. First, the predictor variables (user
participation and the moderating variables proposed in
Hypotheses 2 through 4) were entered in the regression
equation. Then, the interaction term between user
participation and a moderating variable was entered to the
regression equation. The hypotheses 2 through 4 will be
supported (i.e., the hypothesized variables significantly
moderate the relationship between user participation and
information quality), if the incremental R

is significant.
Each of the changes in R
2
provided by adding an
interaction term to the equation and its significance are
shown in Table 5.
