A 12-week Intervention With Motivational Interviewing and Physical Activity Monitoring, to Enhance the Daily Amount of Physical Activity in Community Dwelling Older Adults - a Randomized Controlled Trial

University of Copenhagen65 enrolled

Overview

To investigate if motivational-interviewing will enhance the expected effect from physical activity monitors, on physical activity in older adults, we will conduct a two-arm randomized controlled trial in 2019. Both groups in the trial will receive a physical activity monitor for everyday use in the 12-week intervention period and a folder with information about the benefits of physical activity in older age. Participants in the intervention group will in addition to the use of the physical activity monitors receive a motivational feedback session by phone of about 20 minutes constructed from the theoretical framework of Motivational interviewing by Rollnick, Miller \& Butler and Social Cognitive Theory by Bandura. The content of the session focuses on investigating the most relevant possibilities and barriers for the participant to increase his or her levels of PA. The primary outcome will be between group difference in average steps per day throughout the intervention period, measured objectively by the physical activity monitor (Garmin Vivofit 3). Secondary outcomes include participant reported outcome measures such as 'International Physical Activity Questionnaire', 'Nordic Physical Activity Questionnaire', 'EQ5D Quality of life questionnaire', 'UCLA Loneliness Scale', 'Self Efficacy for Exercise', and 'Outcome expectancy for Exercise'. To ensure 80% power with an alpha-level on 0.05, we will include 128 participants. The study will enroll in March 2019.

Interventions

Motivational interviewsBEHAVIORAL

During the 12-week intervention, the participants will receive seven telephone calls from a physical therapist. The interviews will be held in week 1, 2,3,5,7,9, and 12. The telephone call will consist of a motivational interview focused on enhancing the daily level of physical activity in the participants. MI is a form of counselling aiming at prompting increases in self-efficacy, which may leave people more open to and invested in changing their behaviours and shows potential for significant effects for exercise behaviour change. In addition to the telephone based motivational interviews, the experimental group will also receive the "base intervention" which is described in detail under the "control intervention paragraph".

Base interventionBEHAVIORAL

The "base intervention" consists of a physical activity monitor (PAM) for everyday use in the intervention period and a pamphlet with information about Danish recommendations on physical activity in aging populations. The PAM will be the Garmin Vivofit 3 monitor linked to a pre-specified Garmin Connect account. The participants will be asked to install the Garmin Connect application on their smartphone and use the given ID/password in the app. The participants will be asked to wear the monitor 24-hours a day for the 12-week intervention period. The participants can use the PAM as they like but they will be asked to try to use the PAM and the application to enhance their daily level of physical activity.

Outcomes

Primary Outcomes

Individual intervention period average of PAM measured steps per day

Daily step counts will be objectively measured by the PAM.

Time frame: A daily average of the 12 weeks of intervention

Secondary Outcomes

International Physical Activity Questionnaire

Questionnaire: The seven-item IPAQ-SF measure assesses the types of intensity of physical activity and sitting time that people has done the past seven days as part of their daily lives are considered to estimate total physical activity in MET-min/week and time spent sitting.
