Depression
Why
  1. The registry often attaches Anxiety Disorders to studies about something else, and this study's title and listed conditions do not name it.
  2. The study's listed conditions name Depression.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The study is designed to examine the efficacy of a mobile application implementation of existing best practices in mental health treatment for managing stress, anxiety, and depression.

Read the detailed description

Over 61 million adults in the U.S. experience mental illness in a given year, and only 1 in 3 will receive professional care due to difficulties with access to care, stigma, cost, or time involved in seeking treatment. Pacifica Labs, Inc., produces a Mobile Application ("app") which integrates existing best practices in treatment for stress, anxiety, and depression. One major goal of the app is to empower individuals to effectively self-manage their anxiety and depression. Pacifica has been used in a pilot research study, amongst a group of nonclinical college student volunteers. It was found to have a preventative effect on stress levels (as measured by the DASS-21). The current study is designed to consider a broader population of potential users.

Study Product Pacifica is a mobile app designed to teach users strategies to manage their stress, anxiety, and depression. Users can choose which tools they want to use. The strategies are digital implementations of existing practices in psychology such as thought records, mindfulness meditation \& relaxation exercises, and behavioral activation. Pacifica includes optional "guided paths" of daily psychoeducation and and activities, which users can follow if they like. The app also includes features like mood and health tracking to help individuals notice patterns in their moods and make adjustments to their activities to manage their emotions more effectively. Additionally, there is a "hope board" which serves as a place for users to put inspirational quotes, reassuring photos, or save their completed activities to be reminded of their successes in using the app. Finally, the app offers a peer support community, which is a discussion board for users to connect with others going through similar experiences or who share interests.

The interventions based on Cognitive-Behavioral Therapy (CBT) include the "Thoughts" tool, which educates users about the effect of thinking errors or "cognitive distortions" on emotions and then prompts users to complete a text-based thought record, identify any cognitive distortions, and then challenge those thoughts (via positive reframe). The "Goals" tool is also based on CBT and allows users to create a list of goals to face their fears (in the case of anxiety) or re-engage with life (for those struggling with depression). The tool helps users to track their tasks and progress.

The interventions based on Mindfulness include "Meditations" which provides a suite of activities for users to learn mindfulness, practice deep breathing or body scans, guided relaxation activities, or simply listen to soothing sounds.

Pacifica also offers health-behavior tracking which allows users to monitor activities of their choice such as caffeine consumption, exercise, time spent with loved ones, etc. Users can also track their mood state "How are you feeling?" (scale of 1 = awful to 7 = great). Additionally, users can create and track custom health activities and associate words with their mood from pre-set options such as "stressed" or "happy" or can specify their own words using a hashtag such as "#engaged".

Users are able to see a visual display of their within-app self-monitoring data through the "Progress" function of the app.

The commercially available Pacifica app also allows users to connect to their health care providers through the "My Therapist" tab. This feature will be disabled for the present research study.

Participants in the study will be allowed to use whichever tools they want, in the same way that regular app users can. There is no minimum or maximum "dose" specified.

    Wait List

    Participants will be placed on a wait list and will receive access to the app after 1 month.

Interventions

  • BehavioralPacifica App

    The app contains several activities which are digital implementations of standard psychotherapy practices. Users may select which app elements they would like to use, and when. These app elements include relaxation and meditation activities, tools to examine your thoughts or self-talk, goal setting lists, and mood and health ratings. The app also has a peer support community where users can communicate with others who are having similar experiences. There is no minimum requirement for amount of time spent on any given activity, or in the app in total. The commercially available app has a feature to connect users to their existing healthcare providers, but this feature will not be available to study participants. Study participants may continue to see their existing providers.

What researchers measure

Primary outcomes

  1. Change in Depression

    Change in Patient Health Questionnaire-8 (PHQ-8) score. Range is 0-24. Lower scores indicate less depression.

    Time frame: 2 weeks, 1 month, 3 months

  2. Change in Anxiety

    Change in Generalized Anxiety Disorder-7 (GAD-7) score. Range is 0-19. Lower scores indicate less anxiety.

    Time frame: 2 weeks, 1 month, 3 months

  3. Change in Depression, Anxiety, Stress

    Change in Depression Anxiety Stress Scale-21 (DASS-21) score. We will look at subscales. Ranges for depression, anxiety, and stress are 0-28, 0-20, and 0-33, respectively. Lower scores indicate less severity.

    Time frame: 2 weeks, 1 month, 3 months

Secondary outcomes

  1. Change in Self-Efficacy

    Change in Score on General Self Efficacy Scale. Range is 10-40. Higher scores correspond to higher self-efficacy beliefs.

    Time frame: 2 weeks, 1 month, 3 months

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in May 2018, 6 months.

Of 98 industry-sponsored interventional studies with no phase under Depression, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 18. This study's 6 months is below that.

Counting every sponsor, half of 3,569 studies reached it within 21 months; a quarter within 9 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
