T e revised NEP has fi fteen statements, called items.
(See table 1 on the next page.) Eight of the items, if
agreed to by a respondent, are meant to refl ect endorsement of the new paradigm, while agreement with the
other seven items represents endorsement of the DSP.
Using a Likert scale, a commonly used rating scale,
respondents are asked to indicate their strength of agreement with each statement (strongly agree, agree, unsure,
disagree, strongly disagree).
T e authors asserted that the revised NEP had several
strengths, making it a reliable and valid tool for measuring a population’s environmental world view. In particular, they said the new scale was internally consistent (people who responded to some items in one pattern
tended to respond to other items in a consistent manner)
and that it represented a measure of a single scale (that it
had unidimensionality).
