Mobile Sensing and Support for Depression

Not Applicable

Completed

• Conditions: Depression
• Interventions: Device: Mobile sensing

• Registration Number: NCT02776839
• Lead Sponsor: University of Zurich

Brief Summary

The objective of this study is two fold, first to explore the potential of context sensitive intervention delivery to provide in-situ support for people with depressive symptoms, second to explore the detection of daily-life behavior based on smart phone sensor information to identify subjects with a clinically meaningful depression level.

Detailed Description

To conduct a very first pilot trial, a monocentric, single-arm clinical study is conducted. The study is approved by the local ethics committee of the Canton of Zurich in Switzerland and the Swiss Agency for Therapeutic Products. It is conducted in full accordance with the Declaration of Helsinki, with all subjects providing their electronic informed consent prior to participation. As the main interest lies in a proof of concept of the proposed MOSS app, emphasis is put on real life conditions. A range of different recruitment channels is used to attract subjects from the general public; they include physical flyers, online posts on relevant online bulletin boards and the Google Play Store.

Arm && Interventions

Group	Intervention	Description
Mobile Sensing	Mobile sensing	This phase of the study is designed to develop the app. due to algorithms the app should lern to detect depressive symptoms

Primary Outcome Measures

Name	Time	Method
Patient Health Questionnaire - for depression (PHQ-9)	baseline	subjective depressive symptoms to compare the detected symptoms measured by the app This outcome is needed for the sensing part of the study

Secondary Outcome Measures

Name	Time	Method
Client Satisfaction Questionnaire (ZUF-8)- measures client satisfaction with the app	at post (at least 6 weeks after baseline) however some participants will use the app longer than 6 weeks, maximum 6 months	Client satisfaction with the app is assessed
