EDC for psychiatry trials, where the rating is the data

Depression, anxiety, bipolar disorder and schizophrenia trials live or die on clinician ratings and self-reports. Capture keeps rater scales, participant questionnaires and suicidality assessment in one casebook, with every score attributed to the person who gave it.

  • Clinician scales as site forms
  • Self-reports on participant phones
  • Suicidality follow-up built in

What matters in psychiatry trials

  • Primary endpoints are usually clinician-rated scales such as the MADRS or HAM-D in depression, the PANSS in schizophrenia or the YMRS in mania, supported by CGI ratings and self-reports such as the PHQ-9.
  • Rater variability and placebo response are the two biggest threats to detecting a treatment effect. Rater training, continuity and attribution help with the first; careful design helps with the second.
  • Trials of drugs with central nervous system activity generally assess suicidal ideation and behaviour at every visit, commonly with the C-SSRS.
  • Participant-reported outcomes work well on participants' own phones, but clinician ratings belong on site forms completed during the visit.
  • Licensed scales can have their licence recorded on the form, with collection blocked if it lapses.

Endpoints

Rating scales are the endpoint, so treat them like one

In most therapeutic areas the primary endpoint is a lab value, an image or an event. In psychiatry it is usually a number assigned by a trained rater after a structured interview. That makes the rating process itself part of the measurement: who rated, how they were trained, whether the same rater followed the participant, and whether they knew anything that could bias the score.

An EDC for psychiatry therefore has to do more than store totals. It should capture each item so scores can be checked and verified, attribute every value to the person who entered it, and make it easy to see when a participant's rater changed. In Capture, each clinician scale is a site form with one field per item and a range check on each, and the field-level audit trail records who entered and changed every value.

Common scales by indication

Major depressive disorder trials commonly use the MADRS or the 17-item HAM-D as the primary endpoint, with CGI-S and CGI-I, and self-reports such as the PHQ-9. Generalised anxiety disorder trials use the HAM-A and often the GAD-7. Schizophrenia trials rely on the PANSS; bipolar mania trials on the YMRS. Most also include sleep and functioning measures, such as the Insomnia Severity Index.

Blinded and independent raters

Side effects can reveal treatment assignment to a rater who also manages safety. Many psychiatry trials therefore separate the efficacy rater from the clinician who reviews adverse events. That separation is set in your procedures and role assignments; in Capture, blinded roles never see treatment allocation, and the audit trail shows which user entered each form.

Safety

Suicidality assessment that cannot be missed

Positive answers on suicidality items should reach the investigator the same day. Custom-value edit checks on the relevant C-SSRS questions, PHQ-9 item 9 or a scale's suicidal thoughts item raise a high-priority auto-query in the site action list, and serious events flow into the adverse event workflow with routed safety alerts.

  • High-priority auto-queries on positive findings.
  • SAEs routed with acknowledgement and investigator sign-off.

Self-report

Questionnaires on the participant's own phone

Self-reported outcomes such as the PHQ-9, GAD-7 and sleep measures run in the phone browser from a secure link, with reminders and completion windows. Participants do not install anything, and sites see completion on the dashboard.

  • Secure link by email or SMS, no app.
  • Reminders when due, the next day and before the window closes.
  • At-risk participants highlighted before compliance drops.

Schedule

A typical 8-week depression trial schedule

Weekly or fortnightly ratings early on, when change is fastest, then less often. Built once, the schedule applies identically at every site, with visit windows flagging late assessments.

Design

Placebo response is a data problem as well as a design problem

High and variable placebo response has sunk many psychiatric drug trials. Much of the answer lies in design (population, endpoints, duration, number of sites), but data practices contribute too. Inflated baseline scores, where raters under enrolment pressure score participants just above the entry threshold, show up as large early "improvement" in both arms. Inconsistent rating between sites adds noise that masks real effects.

Three data practices help. First, record item-level baseline scores so blinded data review can look for clustering just above the inclusion threshold. Second, keep raters consistent and trained, and review rater attribution before interim analyses. Third, collect self-reported outcomes alongside clinician ratings, since a divergence between the two can signal rating problems. None of these needs special software; they need item-level, attributed data in one place.

FAQ

Questions teams ask before they switch

Something not covered here? Ask us directly.

What makes EDC for psychiatry trials different?

The primary endpoints are usually clinician rating scales, so rater attribution, item-level capture and consistent administration matter as much as the values. Suicidality assessment at each visit is also common.

Can Capture capture MADRS, HAM-D or PANSS?

Yes, as site forms with one field per item and range checks. Obtain each scale and any licence from its rights holder; licence details can be recorded on the form.

How are positive suicidality findings handled?

Custom-value edit checks raise high-priority auto-queries to the site, and serious events go through the adverse event workflow with routed alerts and sign-off.

Can efficacy raters be kept blind?

Blinded roles never see treatment allocation, and the audit trail records who entered each form. Keeping raters separate from adverse event review is defined in your procedures and role assignments.

Do participants need an app for self-reports?

No. Questionnaires open in the phone browser from a secure link.

Can I try it before committing?

Yes. The free sandbox has every feature, with no credit card and no time limit.
