Preliminary Why this matters to you Expert discussion

Early or partial results. Treat as a signal, not a conclusion.

AI Summary

This is a registered pilot study of a mobile phone app delivering depression treatment (OHDC-DC) to African Americans with depression. The study is actively recruiting and has not yet reported results; it is designed to assess feasibility and preliminary efficacy using validated depression and anxiety symptom scales measured at baseline and approximately 12 weeks post-intervention.

What was studied

Interventional, Single Group, Open label, Treatment purpose. Depression, Depressive Disorder, Depressive Symptoms; age from 18 Years. Intervention: Oh Happy Day Class-Digital Connections (OHDC-DC). n = 8. 1 site: United States.

Key findings

Safety

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.

Who this may help

Clinicians and researchers should note that this is a small, early-phase study with no comparator arm and no reported outcomes. Results, when available, will provide preliminary feasibility and safety data only and should not guide clinical practice without larger, controlled follow-up trials.

Plain-language summary

This is an uncontrolled pilot study with very small planned enrollment (n=8) and no comparator arm, designed to test feasibility and gather preliminary data on a behavioral mobile app intervention for depression in African Americans.

Study design

As stated by the source record.

MethodsPrimary outcome measures: Change in Personal Health Questionnaire Depression Scale score (assessed at Baseline to one month post-intervention (approximately 12 weeks)); Change in Generalized Anxiety Disorder 7-item (GAD-7) score (assessed at Baseline to one month post-intervention (approximately 12 weeks)); Change in Quick Inventory of Depressive Symptomatology (QIDS) (assessed at Baseline to one month post-intervention (approximately 12 weeks)); Satisfaction with intervention (assessed at 12 weeks)

Clinical bottom line

Caveats

This is a registry record; no results have been reported or published.
Very small planned sample size (n=8) with no control group limits generalizability and statistical power.
No sample size calculation, power analysis, or justification for sample size is stated.
Detailed inclusion/exclusion criteria, enrollment location(s), intervention protocol details, and analysis plan are not described in this registry excerpt.

Evidence assessment

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

Study design

limited

Single-arm pilot with no control group or comparator arm.

Directness

strong

Measures depression and anxiety directly using validated scales (PHQ-9, GAD-7, QIDS).

Consistency

insufficient

No results reported; consistency cannot be assessed from registry record alone.

Risk of bias

limited

No blinding mentioned; single-arm design precludes allocation concealment and comparator masking.

Sample adequacy

insufficient

Planned enrollment of only 8 participants is very small; no power calculation stated.

What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.

Source abstract

Registry record from ClinicalTrials.gov (NCT06206226). This is a study registration, not published results. Lead sponsor: University of Wisconsin, Madison. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 8 participants (ESTIMATED). Conditions: Depression, Depressive Disorder, Depressive Symptoms. Interventions: BEHAVIORAL: OHDC-DC. Primary outcome measures: Change in Personal Health Questionnaire Depression Scale score , Baseline to one month post-intervention (approximately 12 weeks); Change in Generalized Anxiety Disorder 7-item (GAD-7) score , Baseline to one month post-intervention (approximately 12 weeks); Change in Quick Inventory of Depressive Symptomatology (QIDS) , Baseline to one month post-intervention (approximately 12 weeks); Satisfaction with intervention , 12 weeks. Brief summary: The goal of this clinical trial is to see if a mobile phone app can deliver depression treatment to African Americans who are depressed. The main question it aims to answer is if this treatment is effective in reducing symptoms of depression. Participants will attend six 90-minute weekly classes via an app on their phone, and will be asked to complete surveys every week. Participants can expect to be in the study for four months.
