Evaluation of a Crowd-Powered Web Platform for Depression and Anxiety

Not Applicable

Completed

Conditions: Depression, Anxiety

Interventions: Behavioral: ADAPT Platform (Treatment)
Behavioral: ADAPT Comparison (Control)

Registration Number: NCT04226742

Lead Sponsor: University of California, Irvine

Brief Summary: 100 participants will be enrolled in a two-armed randomized controlled trial of the Accumulated Depression and Anxiety Plans and Treatments (ADAPT) platform which integrates internet Cognitive Behavioral Therapy (iCBT) to determine impact on symptoms of depression and anxiety. This trial will pilot the effectiveness of the ADAPT platform, and evaluate the extent to which the ADAPT platform engages putative targets of personal relevance, skills use, and skills mastery.

Detailed Description: The investigators will enroll 100 participants in a two-armed randomized controlled trial of the ADAPT platform (iCBT). Participants will be randomly assigned to receive either the ADAPT platform (treatment) or a similar self-guided platform (control) that contains the didactic material (learning) but lacks the ADAPT platforms "crowd" features. Participants will use their assigned platform for a treatment period of 8 weeks. Participants will receive trial assessments at baseline, week 4, and week 8 (post-treatment). Follow-up evaluations will occur at 16 weeks to evaluate maintenance of gains. This pilot effectiveness trial aims to determine the impact on symptoms of depression and anxiety and whether the platform engages the putative targets of personal relevance, relationship, resulting in increased skills mastery and skills use.

Arm && Interventions

Group	Intervention	Description
Treatment	ADAPT Platform (Treatment)	Participants randomly assigned to this condition will receive the ADAPT platform (treatment) for a treatment period of 8 weeks.
Control	ADAPT Comparison (Control)	Participants randomly assigned to this condition will receive a similar self-guided platform (control) for a treatment period of 8 weeks.

Primary Outcome Measures

Name	Time	Method
Anxiety Scores at 16 Weeks	Absolute scores at Week 16	The primary outcome of symptoms of anxiety will be measured with the self-report anxiety subscale of the Depression Anxiety Stress Scale (DASS). The subscale for anxiety ranges from 7 to 28 with lower values (lowest value = 7) indicating lower levels of anxiety and higher values (highest value = 28) indicating higher levels of anxiety.
Depression Scores at Week 16	Absolute scores at Week 16	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.

Secondary Outcome Measures

Name	Time	Method
Cognitive and Behavioral Skills Scores at 16 Weeks	Absolute scores at Week 16	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.
Accountability Scores at 16 Weeks	Absolute scores at Week 16	A secondary outcome is the Supportive Accountability Questionnaire (SAQ), which produces a single score than ranges from 7-91. Data reported are the SAQ total scores with lower levels indicating less supportive accountability and higher values indicating greater supportive accountability.
Self-efficacy Scores at 16 Weeks	Absolute scores at Week 16	A secondary outcome is the Coping Self-Efficacy (CSE), which produces a single score that ranges from 0-260 with lower scores representing lower coping self-efficacy and higher scores indicating higher coping self-efficacy.
Social Functioning Scores at 16 Weeks	Absolute scores at Week 16	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.
