Predicting Effectiveness of Light Treatment for Winter Seasonal Affective Disorder

This study is exploring behavioral or lifestyle intervention for people with depression. Participants may complete study visits, assessments, or follow-up activities defined by the research team. Direct benefit is not guaranteed. The detailed objective is not always clearly listed in the public registry; the study team can confirm.

This appears to be a device / app / digital / technology study. The phase is not clearly listed in the public registry. Phase is mostly relevant for medication studies and some device studies. For this study, it may be more useful to look at what is required, the duration, visits, and eligibility criteria.

The public registry appears to mention tobacco, nicotine, alcohol, cannabis, or another addiction-related topic. Ask the study team whether you need to want to stop, reduce, already be abstinent, or simply meet use-related criteria. Eligibility must be confirmed by the study team.

You may need to use a device, app, or digital tool for a defined period.

If the study uses a device, app, or digital tool, check what data is collected, who can access it, how often you need to use it, and what happens if the tool detects a concerning signal. For any mental health study, also ask who to contact if you feel worse, whether participation may affect current treatment, whether you can stop, and who confirms eligibility.

The likely practical burden appears moderate. Things to check include long follow-up or multiple visits, digital/device data. Ask the study team about duration, visits, possible compensation, data access, and what happens if you want to stop.

This study is sponsored by University of Maryland, Baltimore, which appears to be a university. If available, it can be useful to check the sponsor website, collaborators, investigator affiliation, and the official registry before deciding. HopeStage does not judge the quality of a sponsor or researcher, but helps you identify what to verify.

The registry indicates that this study is completed. It may still be useful for understanding the research, but you are unlikely to be able to join.
