Objective:
To study characteristics of importance for participation in a diet and physical exercise prevention programme.
Setting:
Primary Health Care, Sollentuna, and the Karolinska Hospital, Stockholm, Sweden.
Subjects:
A sample of 187 men, aged 35-60, with increased risk factors for CHD, were invited to a 6-month prevention programme. Participants (n = 158) were randomized into a diet group, a physical exercise group, a diet and physical exercise group, and a control group. Twenty-seven men, who declined participation, formed the group of nonparticipants.
Design:
Participants and nonparticipants were compared with respect to health beliefs, health knowledge, CHD risk factors, demographic and personality factors.
Main Outcome Measures:
Characteristics of men participating and not participating in the intervention trial.
Results:
Nonparticipants, compared with participants, believed less in the benefits of dietary change and perceived the health threat of stroke and myocardial infarction as less serious. Nonparticipants had a better knowledge of a number of risk factors for cardiovascular disease.
Conclusion:
Belief in treatment efficacy and perceived health threat, rather than health knowledge, predicted initial participation in a non-pharmacological intervention trial.

Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
