The study postulates that this may be due to the
difficulty in operationalizing the social norm and perceived
behaviour control constructs which in the SEA policy model
has been aggregated as a single construct and termed as
Barriers. Furthermore, this may also be compounded by the
study respondent group consisting of policy implementers
compared to the public respondents in the previous studies.
This may also explain the inconsistent findings of different
environmental behaviour studies on the above constructs
(Grob, 1995; Ramayah et al., 2012; Tonglet et al., 2004). The SEA
model has also included perception of external constraints as
a distinct construct termed Enablers which enables the model
to distinguish between internal constraints which are within the ability of the individual/organization to influence and
external constraints outside of the individual/organization
sphere of influence but is perceived necessary for the
successful integration of the environmental behaviour. In
the SEA policy model this external enabler includes public
participation and capacity building of policy actors for SEA
integration in policy planning.
