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

Study Overview
=================
Brief Summary
-----------------
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<br>Participants receive a 2-hour lesson (at school) promoting active transport for short distance travel to various destinations. | Other: Active transport lesson<br> <br> |
| Experimental: active transport lesson and Facebook group<br>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<br> <br> |
| No Intervention: control group<br>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) |
