Methodology
The methodology will be discussed in terms of preliminary testing of the
questionnaire, sampling and data collection and, lastly, data analysis and
its evaluation.
Preliminary testing of questionnaire
Prior to data collection, the survey instrument was pre-tested for content
validity through two stages. In the first stage, we asked eight experienced
researchers to review and comment on the questionnaire to determine
the clarity, ambiguity and appropriateness of the items used to operation-
alize each construct. We have prepared a list with all constructs’ descrip-
tions, including the definition and main aim of measurement for each
one. Then, based on the feedback received from these eight researchers,
we modified the instrument in order to enhance the clarity and appropri-
ateness of the measures. In the second stage, we asked five environmental
managers from five different industry sectors and different company sizes
to agree to a one-hour meeting in which they would review and comment
on the questionnaire. We asked them in face-to-face interviews to review
and comment on the questionnaire regarding its clarity, ambiguity, com-
pleteness, readability and structure. Finally, feedback on the question-
naire was also received from person who was dealing with ISO 14001 cer-
tification. We used their feedback to further improve the questionnaire.
In this study, we have measured 15 latent variables: the com-
mand-and-control instrument, the economic incentive instrument, cus-
tomer demand, managerial environmental concern, expected benefits,
