Effectiveness of and Engagement in a Mobile Exergame With Tailored Feedback

Not Applicable

Completed

• Conditions: Physical Activity; Health Behavior
• Interventions: Behavioral: No game; Behavioral: 'SmartLife' without tailored feedback; Behavioral: 'SmartLife' with tailored feedback

• Registration Number: NCT03659604
• Lead Sponsor: University Ghent

Brief Summary

The aim of this study is to investigate the effectiveness of the 'SmartLife' intervention on reducing sedentary behavior and increasing physical activity among adolescents and to investigate the engagement in the exergame. This will be compared in three groups: an intervention group that will receive a tailored exergame; an active control condition that will receive a non-tailored exergame; and a passive control condition that receives no intervention.

Detailed Description

The aim of this study is to investigate the effectiveness of the 'SmartLife' intervention with tailored feedback on sedentary behavior and physical activity among adolescents and to investigate the engagement in the exergame. One intervention group will receive a version of the exergame that tailors feedback. This means tailored feedback will be based on data from a sensor which is integrated in a T-shirt and paired to the game. The active control group will receive a different version of the game, that does not provide tailored feedback.

Both groups will be compared to investigate their level of engagement in the game. A passive control group will be included that will be asked to continue their daily routines as usual. All three groups will be compared to determine the effectiveness of the 'SmartLife' intervention on physical activity and sedentary behavior.

Arm && Interventions

Group	Intervention	Description
Passive control	No game	School classes will not receive any intervention, thus no game.
Active control without tailored feedback	'SmartLife' without tailored feedback	'SmartLife' without tailored feedback: School classes will receive the developed 'SmartLife' intervention without tailored feedback.
Experimental with tailored feedback	'SmartLife' with tailored feedback	'SmartLife' with tailored feedback: School classes will receive the developed 'SmartLife' intervention with tailored feedback, that is based on data from a sensors that is integrated in a T-shirt.

Primary Outcome Measures

Name	Time	Method
Change in objectively measured physical activity (PA)	Baseline, 4 weeks, 8 weeks	Change in amount of total physical activity and moderate-to-vigorous physical activity, measured via accelerometers

Secondary Outcome Measures

Name	Time	Method
Change in determinants of PA	Baseline, 4 weeks, 8 weeks	Change in attitude, parental support, friends' co-participation, perceived social norm, self-efficacy, perceived benefits, perceived barriers, measured by validated items (questionnaire)
Change in determinants of SB	Baseline, 4 weeks, 8 weeks	Change in attitude, self-efficacy, personal norm, social norm, social support of sedentary behavior (measured for the context of 1. TV viewing, game-play, and computer use), measured by validated items (questionnaire: correlates of context specific SB, Busschaert, 2015). Items are measured on a 5-point Likert scale (strongly disagree=1 - strongly agree=5). The average for each correlate will be calculated (meaning that sub scales for one correlate (e.g. attitude) will be combined).
Change in behavior of PA	Baseline, 4 weeks, 8 weeks	Change in active transportation mode to school, measured by validated items (questionnaire: Flemish physical activity questionnaire, Verstaete et al., 2003), that measures the minutes engaged in different types of transportation to school. An average score for each component (walking, cycling, active transportation, passive transportation) will be calculated. Values will be indicated by minutes per day, whereby higher values will represent a better outcome, after reversing passive transportation.
Differences in basic need satisfaction	4 weeks	Differences in basis need satisfaction between intervention group and active cotrol group, measured via 14 validated items (questionnaire)
Change in subjectively measured Body Mass Index (BMI)	Baseline	Change in BMI, measured via self-reported weight and height
Change in objectively measured sedentary behavior (SB)	Baseline, 4 weeks, 8 weeks	Change in amount of total sitting time, measured via accelerometers
Differences in engagement	4 weeks	Differences in engagement between intervention group and active control group, measured by validated items (questionnaire: Kids Game Experience Questionnaire), that measures immersion, narrative, pos/neg. affect, flow, absorption/involvement, transportation/immersion, challenge, tension/frustration. A scale ranges from 0 to 4, whereby higher values represent a better outcome. The average scores of the subscales represent each component, and a final averaged score for the GEQ questionnaire will be calcualted.
