This investigation used a 7-point Likert scale to rate the
questionnaire responses from 1 (strongly disagree) to 7 (strongly
agree) using questions modified from previous consumer behavior
studies. First, variable dimensions of questionnaire forms were
obtained from the literature. These dimensions were then
modified to develop initial questionnaires based on industry
features (e.g., service quality, food quality and delivery speed).
Third, tests were repeatedly administered to four professional
restaurant managers. Fourth, pilot runs of the questionnaire were
administered to fifty-four and fifty customers in the Tayih Landis
restaurant in Tainan city and the Farglory hotel restaurant in
Hualien city, respectively. Questions were eliminated in response
to (1) respondent suggestions and (2) item factor loading.
Operational definitions for all variables and measurement tools
are presented below.
