Trial Outcomes & Findings for A Study to Test the Effectiveness of Different Interventions to Improve Physical Activity in Adults. (NCT NCT04902014)

NCT ID: NCT04902014

Last Updated: 2023-07-27

Results Overview

Changes in motivation for physical activity as described by the self-determination theory was assessed using the Behavioral Regulation in Exercise Questionnaire, v3 (BREQ-3) and the Basic Psychological Needs in Exercise Scale (BPNS). The BREQ-3 uses four survey items per motivational subtype (Amotivation, External, Introjected, Identified, and Integrated Regulation, and Intrinsic Motivation). The BPNS uses three of four items per psychological need (Autonomy, Competence, and Relatedness) The raw scores per subtype or need are averaged for one subtype and need score per participant. The scale ranges from 0 (does not apply to me) to 4 (applies to me very much). Therefore, subtype or need score closer to ) indicate low levels of that subtype whereas scores closer to 4 indicate higher levels of that subtype or need.

Participant Flow

Participants were recruited through a variety of means including flyers on the Colorado State University campus, social media, and mass emails. Participants were recruited and admitted into the study on a rolling basis from April 2020-June 2020.

Consented participants were stratified by sex (male/female) and age (20-29, 30-39, 40-49, 50-59, and 60-69 y/o.) before being randomized to one of four conditions.

Education
Education: These participants will receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting. These participants will not do any other study related activities. At the conclusion of the study, these participants will be offered the chance to participate in one MI session.
Motivational Interviewing
Motivational Interviewing: The individuals will be scheduled for and participate in six biweekly in person SDT based MI sessions. These sessions will take place in the HPCRL at CSU. The MI sessions will be conducted by a PhD student who has been trained by a MI practitioner. Participants will be provided a log book and will be asked to log their PA, with the goal of completing at least 150 minutes of PA per week. They will set biweekly PA goals, which will be discussed in the MI sessions. These participants will also receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting.
Wearable Fitness Tracker
Wearable Fitness Trackers: Individuals assigned to this experimental condition will be given a wrist-worn WFT and will be instructed to wear it for the duration of the study. They will also download the corresponding mobile application on their smartphones. They will be trained by a member of our team on how to utilize the WFT and mobile application. The intended WFT tracks daily steps, miles traveled, kcals expended, and daily activity time. This device provides these data to the wearer via a small screen. Participants will be instructed to aim to complete at least 150 minutes of PA per week. Researchers will have the capability to track participant daily PA via the WFT and associated API. These individuals will be asked to set biweekly PA goals. These participants will also receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting.

PRIMARY outcome

Timeframe: Baseline and at 12 weeks.

Changes in motivation for physical activity as described by the self-determination theory was assessed using the Behavioral Regulation in Exercise Questionnaire, v3 (BREQ-3) and the Basic Psychological Needs in Exercise Scale (BPNS). The BREQ-3 uses four survey items per motivational subtype (Amotivation, External, Introjected, Identified, and Integrated Regulation, and Intrinsic Motivation). The BPNS uses three of four items per psychological need (Autonomy, Competence, and Relatedness) The raw scores per subtype or need are averaged for one subtype and need score per participant. The scale ranges from 0 (does not apply to me) to 4 (applies to me very much). Therefore, subtype or need score closer to ) indicate low levels of that subtype whereas scores closer to 4 indicate higher levels of that subtype or need.

Education
n=10 Participants
Education: These participants will receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting. These participants will not do any other study related activities. At the conclusion of the study, these participants will be offered the chance to participate in one MI session.
Motivational Interviewing
n=10 Participants
Motivational Interviewing: The individuals will be scheduled for and participate in six biweekly in person SDT based MI sessions. These sessions will take place in the HPCRL at CSU. The MI sessions will be conducted by a PhD student who has been trained by a MI practitioner. Participants will be provided a log book and will be asked to log their PA, with the goal of completing at least 150 minutes of PA per week. They will set biweekly PA goals, which will be discussed in the MI sessions. These participants will also receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting.
Wearable Fitness Tracker
n=10 Participants
Wearable Fitness Trackers: Individuals assigned to this experimental condition will be given a wrist-worn WFT and will be instructed to wear it for the duration of the study. They will also download the corresponding mobile application on their smartphones. They will be trained by a member of our team on how to utilize the WFT and mobile application. The intended WFT tracks daily steps, miles traveled, kcals expended, and daily activity time. This device provides these data to the wearer via a small screen. Participants will be instructed to aim to complete at least 150 minutes of PA per week. Researchers will have the capability to track participant daily PA via the WFT and associated API. These individuals will be asked to set biweekly PA goals. These participants will also receive general physical activity guidelines education and information on strategies to reach the recommended amount of activity per week during the initial baseline assessment meeting.
Wearable Fitness Tracker+
n=10 Participants
Wearable Fitness Tracker+: These individuals will be given the wrist-worn WFT, be instructed to wear it for the duration of the study AND be scheduled for six SDT based MI sessions. These participants will also be trained by a member of our team on how to utilize the WFT and associated application. They will be instructed to aim to complete 150 minutes of PA per week. These participants will be asked to set biweekly PA goals which will be discussed in MI sessions. Researchers will have the capability to track participant daily PA via the WFT and associated API.
