Although some studies have shown evidence of short-term
effects regarding a behavioural outcome, few were able to
demonstrate this in the long-term[31].Messaging which provides
advice on specific healthy behaviours to the exclusion of
other considerations can lack effectiveness or even act against
positive behavioural change. Johnson et al. [52] suggest that
“providing information about a particular issue. . .can have
unintended consequences such as reducing attention about
important issues. . .or increasing focus on only a single corrective
action” (page 499).
