Background and study aims
Physical inactivity is a worldwide growing problem with one out of five adults not doing enough exercise. It is a risk factor for chronic diseases such as diabetes and cardiovascular diseases, being overweight and several cancers. Regular physical activity (PA) has a number of fitness and health related benefits and is associated with an estimated 30% reduction in risk for all-cause mortality (death) among adults. Regular, moderately intense exercise is important for a person’s physical and mental well-being, and the prevention and management of many chronic diseases. When people start doing PA, they often stop and become inactive again, even when they take part in PA programmes (or interventions). Many people become inactive again when intervention support is no longer provided. However, only sustained PA has an beneficial effect on health and the prevention of illness. It has been suggested that future PA interventions should include behavior maintenance strategies. These strategies should focus on what is most likely to keep people exercising. The barrier-belief approach concentrates on these proven behavior change strategies - change means reach goals, set (different) goals, restructure beliefs, induce acceptance. These are all applied to target the core of problems with starting and maintaining PA. Using well-known theories and strategies, the barrier-beliefs approach composes a way of counseling around the central construct of barrier-beliefs. The aim of this study is to assess how well a tailored BB counseling intervention performs compared with a group education program in general practice. A new perspective of changing behavior will be examined in primary care, called the BB Counseling Approach. The goal of the developing lifestyle intervention is to decrease medical complaints and care intake, to increase PA-behavior in subjects.

Who can participate?
Adults who consult their general practitioner, who are physically inactive.

What does the study involve?
Participants are randomly allocated into one of three groups. Those in group 1 receive BB counseling intervention for a maximum of six months. Each participant decides himself how often they need an appointment with the counselor (with a maximum of 15 appointments during half a year). Those in group 2 receive a group education intervention. It encourages people to change their behavior by helping them to improve their knowledge about healthy behavior and achieve firm goals. All participants attend 5 group meetings and 2 one-to-one meetings. Those in group 3 are in the control group and do not receive an intervention.

What are the possible benefits and risks of participating?
The risk of injury or complications with this study is minimal. However, it is possible in any experiment that harmful effects may unexpectedly occur. Every precaution will be taken to prevent or minimize the occurrence of adverse events. These precautions include proper subject counselling, allowing only qualified counselors to support the process and administer all measurements. If injury does occur during counselling, the principal researcher will administer appropriate care and refer subjects for proper medical treatment.

Scientific titleEffect of the barrier-belief counseling on physical activity in inactive adults.
Study acronymBB Counseling Approach (BBCA)
Study objectivesThe barrier-belief counseling approach (BBCA) in the counseling of a physical activity (PA) in inactive adults is more effective than the usual care in primary health care setting.
Ethics approval(s)The Review Committee of the University Medical Centre in Groningen, The Netherlands 01/08/2010, ref: NL30895.042.10
Health condition(s) or problem(s) studiedThe PA-behavior of inactive adults in primary care will be studied.
Intervention1. The intervention group
In PA counseling, barrier-beliefs (BBs) are addressed using four different BB behavior change strategies. The BB counseling aims to develop an individual pattern of PA for the long term that is adapted to the (often limited) motivation of the client, thereby preventing the occurrence of BBs. The client will learn to cope with factors that may inhibit PA in the future. This perspective of counseling barriers focuses mainly on exploring and resolving individual barriers experienced by subjects in the process of changing behavior and releasing guidelines to PA.
1.1. Channel: individual counseling sessions
1.2. Length: maximum 6 months and maximum 15 appointments.
Participants will be tested at 4 moments; T1: a pre-test before starting the intervention; T2: a post-test immediately after completing the intervention; T3: 6 months after T2; T4 6 months after T3.
2. Group education intervention (control group A)
The core of the group education intervention, or the “standard group intervention”, is a directive educational style for eliciting behavioral change by helping subjects to improve their knowledge about healthy behavior and achieve predetermined goals in which norms and guidelines will be leading.
2.1. Channel: group sessions;
2.2. Frequency: 7 moments of contact (5 group meetings and 2 individual meetings). Participants will be tested at 4 moments; T1: a pre-test before starting the intervention; T2: a post-test immediately after completing the intervention; T3: 6 months after T2; T4 6 months after T3.
3. Control group B
This group will receive no intervention, only a pre-test (T1) and 6 months later a post-test (T2).
