An Intervention to Promote Active Transport for Short Distance Travel in Older Adolescents

The purpose of this study is to determine whether a theory- and evidence-based intervention aiming to promote active transport for short distance travel among older adolescents is effective in increasing attitude, subjective norm, self-efficacy, awareness and habit towards active transport, and intention to use active transport after obtaining a driving license.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: active transport lesson; Participants receive a 2-hour lesson (at school) promoting active transport for short distance travel to various destinations.	Other: Active transport lesson
Experimental: active transport lesson and Facebook group; Participants receive a 2-hour lesson (at school) promoting active transport for short distance travel to various destinations. Furthermore, they are asked to join a Facebook group on active transport in which 3 messages per week are posted during an eight-week period. The Facebook posts aim to promote the use of active transport for short distance travel.	Other: Active transport lesson and Facebook group
No Intervention: control group; Participants in the control group do not receive the active transport lesson or the Facebook group.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in perceived benefits towards active transport	Perceived benefits towards active transport (e.g. health, cost, parking lot, independence,...) will be assessed via seventeen items with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in perceived barriers towards active transport	Perceived barriers towards active transport (e.g. time, accidents, weather, sweating,...) will be assessed via twenty-one items with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in subjective norm towards active transport	Subjective norm towards active transport will be assessed via three items (family, friends, partner) with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in self-efficacy towards active transport	Self-efficacy towards active transport (e.g. bad weather, darkness, when tired,...) will be assessed via eleven items with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in awareness towards active transport	Awareness towards active transport (e.g. ecology, health benefits, private car ownership,...) will be assessed via eight items with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in habit towards active transport	Habit towards active transport (e.g. walking or cycling for transport is something I automatically do) will be assessed via four items with a five-point answer format.	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
Change in intention to use active transport after obtaining a driving license	Intention to use active transport after obtaining a driving license will be assessed via three items with a five-point answer format (e.g. how much do you want to keep using active transport for short distances after obtaining a driving licence).	The outcome will be measured at baseline (before start intervention), posttest (1 week after the intervention) and follow-up (8 weeks after the intervention)
