Human intervention study investigating the PRECIOUS Food intake tool.

Study timescale: From 01 May, 2016 to 30 July, 2016

This intervention study is being conducted as part of the wider project ‘PREventive Care Infrastructure based on Ubiquitous Sensing’ (PRECIOUS), which has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 611366. Overall, PRECIOUS aims to provide a preventive care system to promote healthy lifestyles, and as part of this PRECIOUS aims to develop a new monitoring tool and will investigate the use of motivational techniques to improve usage and motivational levels.

The aim of this intervention study is to investigate whether the motivational aspects of the PRECIOUS food intake tool have an impact on user usage and perceived motivation. The study will also asses the usability of the PRECIOUS food intake tool.

The objectives of this intervention study are to;

  1. Assess whether there is a change in perceived motivation of a user when the motivational aspect of the PRECIOUS food intake tool are switched on.
  2. Assess whether there is a change in logging of food intake behaviour when the motivational aspect of the PRECIOUS food intake tool are switched on.
  3. Assess the usability of the PRECIOUS food intake tool

This study will asses two different elements of the overall food intake application (a food diary element and a challenge element), with each aspect being assessed by sixty participants.

Once recruited and given consent, the participants will be divided into four groups.

For all four groups a minimum of 30 participants will be firstly asked to complete an online attitudinal questionnaire on day 0. On completion of this questionnaire they will then be asked to download and use either the diary aspect (group 1 &2) or fruit and vegetable challenge aspect (group 3&4) of the PRECIOUS food intake app for 14 days. After 7 days, the participants will be prompted to complete another online questionnaire. After completion of this questionnaire, they will be asked to continue using the app for a further 7 days. After 14 days, the participants will be prompted to complete a final online questionnaire.

For groups 1&3, on completion of the questionnaire after 7 days, motivational elements of the PRECIOUS food intake app will be switched on remotely. The participants will not be made aware of this.

Data will also be collected remotely from the PRECIOUS server regarding the participants use of the tool during the 14 day user trial.

Source of funding: European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 611366.

Results of the study will be reported on the PRECIOUS website; http://www.thepreciousproject.eu/
