Brief summary
Aim: The aim of this study is to assess the short and long-term efficacy of a behavioural change activity program and motivational interviewing to increase physical activity in older adults. Hypothesis 1: Participants who receive a tailored behavioural change program will have higher physical activity levels compared to those who receive a ‘usual care’ education program. Hypothesis 2: Participants who undergo telephone counselling using motivational interviewing (MI) techniques will have higher physical activity levels compared to those who receive the same number of standard telephone contacts. Hypothesis 3: Participants who receive a tailored behavioural change program and telephone counselling with MI will have higher physical activity levels compared to those who received the other programs. Hypothesis 4: Increased levels of physical activity will be associated with greater health benefits such as increased fitness, reduced blood pressure, body weight, depression, stress, anxiety and improved psychological well-being. Hypothesis 5: Self efficacy will mediate the change in physical activity behaviour. METHODS Healthy, non smoking, sedentary, 50-80 year old men and women will be recruited from the community. Participants will be assessed on physical activity, fitness, body weight, blood pressure and psycho-social aspects of mental health such as stress, depression anxiety and well being at baseline, 6 and 12 months. They will be randomly assigned to a ‘usual care’ education program or a ‘behavioural change’ education program. Within each of these programs they will be further allocated to have standard telephone contacts or motivational interviewing (MI) telephone contacts. All participants will be asked to do 150 minutes/week of moderate physical activity for an initial 6 month intervention and a further 6 months of non contact.
Interventions
The study will evaluate the effects of two educational approaches, usual care and behavioural intervention and two motivational techniques, standard instruction and motivational interviewing. The intervention will be for an initial 6 months with a follow-up after a further 6 months during which participants will be asked to continue with their exercise but will not receive any further intervention. All participants will be asked to complete 150 minutes of moderate physical activity per week (3 X
The study will evaluate the effects of two educational approaches, usual care and behavioural intervention and two motivational techniques, standard instruction and motivational interviewing. The intervention will be for an initial 6 months with a follow-up after a further 6 months during which participants will be asked to continue with their exercise but will not receive any further intervention. All participants will be asked to complete 150 minutes of moderate physical activity per week (3 X 50 minutes). All participants will attend a 2-hour workshop. One hour will outline the program, the safety aspects of exercise and participants will take part in a demonstration session. The other hour will be used to cover the specific intervention for each group. The behavioural intervention is based on the Stages of Change Model and consists of information and worksheets including topics such as goal setting, time management and overcoming barriers to exercise. The behavioural intervention will be included in a participant manual and will be briefly outlined (10-15 minutes) in part of the main workshop. The motivational interviewing will be delivered in a 45-minute workshop and will include worksheets included in the manual. It will be followed up with 4 phone calls one every 6 weeks over the initial 6 months, they will be of 10-15 minute duration and start at week 3.
