This study examines: (1) the impact of two methods of giving screening
results on health behaviour and beliefs, evaluated in a randomized co
ntrolled trial. (2) The association between uptake of screening and he
alth risk behaviours and beliefs. Two methods of feedback of screening
results were given: simple informational feedback, and more extensive
feedback, including target-setting and a written contract. At six mon
th follow-up, those who received simple informational feedback had los
t less weight and had increased their exercise less than those who rec
eived more extensive feedback. Attenders believed more strongly in the
relationship between lifestyle and health, perceived themselves as le
ss healthy than others and scored higher on the GHQ than staff who did
not attend for screening. These results suggest that belief in the ef
fectiveness of lifestyle change in promoting health, and anxiety about
health, can influence uptake of screening. Second, the method of pres
enting screening results can influence the impact of screening on subs
equent behaviour change.
