Trial Outcomes & Findings for Evaluation of a Crowd-Powered Web Platform for Depression and Anxiety (NCT NCT04226742)

NCT ID: NCT04226742

Last Updated: 2023-06-29

Results Overview

The primary outcome of symptoms of depression will be measured with the self-report depression subscale of the Depression Anxiety Stress Scale (DASS). The subscale for depression ranges from 7 to 28 with lower values (lowest value = 7) indicating lower levels of depression and higher values (highest value = 28) indicating higher levels of depression.

Measure
Treatment
Participants randomly assigned to this condition will receive the ADAPT platform (treatment) for a treatment period of 8 weeks. ADAPT Platform (Treatment): The ADAPT platform consists of 2 modules based on evidence-based strategies from cognitive-behavioral therapy including cognitive restructuring and behavioral experiments. The platform includes didactic material, interactive tools, and crowd-features. Crowd-features are present to increase personal relevance of content and to promote engagement with the ADAPT platform through accountability. Crowd-features include requesting, responding, and exemplars.
Control
Participants randomly assigned to this condition will receive a similar self-guided platform (control) for a treatment period of 8 weeks. ADAPT Comparison (Control): The control platform is a self-guided version of the ADAPT platform that includes no crowd-features. As such it will include only didactic material on cognitive restructuring and behavioral experiments and interactive tools.

A secondary outcome is the Frequency of Actions and Thoughts (FATS), which assesses the use of cognitive and behavioral skills. Total scores indicate the average of each item rating and range from 0-4. Lower scores indicate less frequent use of cognitive and behavioral skills and higher scores indicate more frequent use of cognitive and behavioral skills.

Functioning will be assessed with the Patient-Reported Outcomes Measurement Information System (PROMIS) Ability to Participate in Social Roles and Activities Scale which produces T-scores that have a mean of 50 and a standard deviation of 10. Lower scores indicate lower participation in social roles and activities and higher scores indicate higher participation in social roles and activities.
