Increasing Physical Activity Through a Motivational Online Intervention Using Pedometers in Sedentary Students

The aim of this study is to analyze the effect of a motivational online intervention (MOI) using pedometers to increase physical activity in a sample of sedentary students. It will be compared three conditions: MOI+PEDOMETER condition (access to a MOI and the use of a pedometer of new generation); MOI condition (access to a MOI and the use of a blinded pedometer); and CONTROL condition (the use of a blinded pedometer).

Study Overview

• Status: Completed
• Conditions: Sedentary
• Intervention / Treatment: Behavioral: Motivational Online Intervention; Behavioral: Pedometer

Detailed Description

Regular practice of physical activity (PA) has shown benefits in physical and mental health. However, the levels of PA are low in the general population. Pedometers and motivational online interventions (MOI) have been used to increase PA levels in sedentary population.

In spite of finding positive outcomes on PA levels when theoretical constructs derived from theories of behavior change and Internet have been used to guide pedometer-based interventions, few interventions have incorporated all these variables together and have analyzed the short-term or mid-term results.

The main objective of this study is to analyze the effect of a short self-administered Motivational Online Intervention (MOI) using pedometers to increase PA levels (primary outcome) and to change different theoretical constructs related to the PA behavior (positive decisional balance, self-efficacy, processes of change, stage of change, and enjoyment) (secondary outcomes) in a sample of sedentary students after 3-weeks intervention (post) and after 3-months (follow-up). It will be compared three conditions: MOI+PEDOMETER condition (access to a MOI and the use of a pedometer of new generation); MOI condition (access to a MOI and the use of blinded pedometer); and CONTROL condition (the use of a blinded pedometer). Hence, two conditions will include components of the "Transtheoretical Model of Change" in the intervention, such as the facilitation of the decisional balance, the increase of the self-efficacy, and the use of experiential and behavioral processes of change (e.g., consciousness raising, counterconditioning, reinforcement management, stimulus control), but only one of these condition will receive the feedback of the pedometer that will allow self-monitoring the behavior.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: MOI and PEDOMETER; Accessing to a motivational online intervention and wearing an unblinded pedometer (in order to receive feedback of the steps taken).	Behavioral: Motivational Online Intervention; The self-administered Motivational Online Intervention developed by the authors was based on the "Transtheoretical Model of Change". It attempts to facilitate the decisional balance, the increase of the self-efficacy, and the use of experiential and behavioral processes of change (e.g., consciousness raising, counterconditioning, reinforcement management, stimulus control). The main objective is to deliver information to increase the motivation to practice physical activity and to set individualized goals. It has a total length of 45 minutes, and it is delivered in a web platform at the beginning of the intervention.; Behavioral: Pedometer; Wearing a pedometer of new generation that provides motivational messages from time to time to motivate the user to increase the physical activity, as well as information in the screen regarding all-day activity: steps taken, calories burned, distance travelled, floors climbed and active minutes.
Experimental: MOI (without PEDOMETER); Accessing to a motivational online intervention and wearing a blinded pedometer (in order to not receive feedback of the steps taken).	Behavioral: Motivational Online Intervention; The self-administered Motivational Online Intervention developed by the authors was based on the "Transtheoretical Model of Change". It attempts to facilitate the decisional balance, the increase of the self-efficacy, and the use of experiential and behavioral processes of change (e.g., consciousness raising, counterconditioning, reinforcement management, stimulus control). The main objective is to deliver information to increase the motivation to practice physical activity and to set individualized goals. It has a total length of 45 minutes, and it is delivered in a web platform at the beginning of the intervention.
No Intervention: CONTROL; Wearing a blinded pedometer (in order to not receive feedback of the steps taken).
