Plain English Summary
Background and study aims
Informing people of their risk of heart disease, along with counselling on what lifestyle choices should be adopted, is the first step towards preventing someone from developing the disease. Most Canadian physicians perform risk assessments on their patients as they are well aware of the importance of promoting regular physical activity. Despite this, 85% of adults in Canada do not meet Canadas physical activity guidelines (which state that adults aged 18-64 should do at least 150 minutes of moderate to vigorous physical activity every week in bouts of 10 minutes or more). This highlights a need to prioritise counselling on physical activity, but time constraints may stop physicians from being able to do this for all their patients adequately. eHealth technology is an innovative way for helping patients to self-manage their heart disease health factors. It follows the same principles of face-to-face counselling by asking people about their health behaviour, their motivation and factors determining motivation and behaviour. The feedback given to a person is based on the answers given and highly tailored to meet each persons individual needs. The aim of this study is to test the feasibility and efficacy of a web-based programme (the intervention) targeting physical activity in patients not reaching Canadas physical activity guidelines.
Who can participate?
Participants aged between 35 and 70 years of age that took part in the Quebec City Prospective Urban Rural Epidemiology (PURE) study (a study looking at health among the local population)
What does the study involve?
Each participant is randomly allocated into one of two groups. The experimental group take part in a web-based physical activity program. Each session takes about 10-15 minutes each and participants are asked to do 8 sessions over the course of 16 minutes. The control group receive their usual standard of care. Both groups complete questionnaires before and after the experimental group have completed the physical activity programme. The programme will be offered to the control group once the study is complete.
What are the possible benefits and risks of participating?
The potential benefits for participants with this research project are:
1. Personalized advice regarding their own physical activity.
2. Knowledge that they have contributed to the advancement of knowledge in the field of promotion of physical activity on the Internet.
This research project has no known physical or psychological risks.
Where is the study run from?
1. Université du Québec à Trois-Rivières (Canada)
2. lInstitut universitaire de cardiologie et de pneumologie de Québec (Canada)
When is study starting and how long is it expected to run for?
April 2014 to September 2014

Feasibility and efficacy of a computer-tailoring (CT) physical activity intervention to promote self management of cardiovascular disease (CVD) risk factors: a pilot randomized controlled trial
To examine the feasibility of adapted Web-based CT intervention. The specific research question is:
Research Question 1. Do intervention initiation and intervention completion regarding PA differ in relation to socioeconomic status and gender?
To determine the efficacy of adapted Web-based CT intervention after three months. The specific research questions are:
RQ 2.1 - What is the efficacy of CT intervention on PA?
RQ-2.2 - Is the intervention equally effective for subgroups differing in socioeconomic status and gender?

Participants will be divided to 2 groups:
1. An experimental group (CT intervention): The intervention group will be invited to participate in eight 10-15 minute Web sessions distributed over a 16-week period
2. A control group (usual care): Will complete a pretest and a post-test. The intervention will be offered to the control group afterwards.
Primary outcome measures
Leisure-time physical activity. The Godin Leisure-Time Physical Activity Questionnaire will be used : a validated French version will assess in both groups the average frequency of light, moderate, and vigorous exercise during free time in a typical week at baseline and 3-month follow-up. Also, forty participants in both groups will receive a blinded pedometer that has been validated. These participants will be instructed about how to wear pedometer correctly and physical activity behaviour will be measured during 7 consecutive days from morning to bedtime at 3-month follow-up.
Secondary outcome measures
Overall trial start date
Overall trial end date
Participant inclusion criteria
