Pilot and feasibility studies in mental health: what are they testing?

A small study may be testing whether research can be carried out as planned. That is a different question from proving a treatment works. Check the protocol’s purpose rather than deciding what “pilot” means from the number of people involved. Catalogue examples below concern bipolarity; they do not confirm the activity, role, age criteria or local availability described in this guide.

Short answer

Pilot and feasibility studies in mental health: what are they testing?

Ask which procedures or arrangements the study is testing and what it is not designed to establish. A pilot may examine recruitment, delivery, participation or measurements. It is not automatically less demanding or low risk, and its findings should not be treated as definitive evidence of benefit for you.

What does pilot mean in this protocol?

NCCIH describes pilot work as testing methods and procedures for a larger study. Feasibility concerns whether an approach can be carried out. Read the actual aims and ask which question is primary. Not every small investigation is a feasibility pilot, and a title alone cannot establish the design or what its results could support.

Which parts of research might be tested?

Examples include whether people can be recruited, appointments delivered, assessments completed or the proposed approach accepted. Ask which of these matters here and whether your feedback is itself research data. These examples are possibilities, not a list of procedures that every pilot includes. The team should explain the measures it actually uses.

What would participation involve?

Request the visit calendar, home activities, assessments and follow-up. Clarify whether staff will ask how practical or acceptable the activities felt. Do not assume a smaller study means fewer visits or less monitoring. Ask about usual care, known risks and uncertainty before deciding, using the same care you would take with a larger study.

What can the findings establish?

A feasibility finding can help researchers decide how to organise later research. It does not by itself establish that an intervention improves health. NCCIH cautions against treating small pilot findings as reliable tests of efficacy or proof of safety. Ask what the study can reasonably conclude and what would require a different, adequately designed investigation.

Will there definitely be a larger study?

A later study is not guaranteed. Methods, assessments, eligibility or the intervention may change, and further funding or review may be needed. Ask whether there is any actual plan and how you could hear about the findings. Joining this pilot does not reserve a place in later research or promise continued treatment.

Which questions help you decide?

Ask: “What is this pilot testing, what would I do, and what would its results still leave unknown?” Add questions about time, support, risks and coordination with current care. Keep your own priorities separate from the scientific aim. You can consider whether the practical commitment is acceptable without predicting your eligibility or the intervention’s benefit.

FAQ

Common questions

Does a small study mean low risk?

No. Ask about the actual procedures and risks; sample size is not an individual safety assessment.

Do promising pilot findings prove effectiveness?

No. Feasibility and definitive treatment-effect questions require different evidence.
