To answer the above research questions, this study examined four demographic
variables: gender, age, education, and income. The study chose four
psychological variables that were considered to be relevant to the use of
community ICTs. Three psychological variables were adopted from Icek
Ajzen’s [30, 33–34] theory of planned behavior, which is a theoretical
model that has been widely applied to various social behaviors, including
media use and information technology use. The theory predicts behaviors
with three psychological constructs: attitude (i.e., attitude toward using the
service), subjective norms (i.e., perceived social pressure to use the service),
and perceived behavioral control (i.e., perceived capability to use the
service).
