| Study characteristics | ||
| Methods | Randomised trial, USA | |
| Participants | 1374 adult patients 87,5% white, 4,5% black, 4% Hispanic, 4% multiracial | |
| Interventions | Patients complete 11 items from the SCL‐90 at starting point and 6 weeks later. In the intervention group a report detailing survey results were given after the initial and 6‐week administration to the clinician. Intervention features Multiple simple feedback (one PROM at multiple times) PROM(s) used as intervention: S‐QoL (Schizophrenia Quality of Life) questionnaire Constructs measured: Symptoms Instrument categories/domains: Generic, Domain/Disease specific (Mental health) Administration features Where PROMs administered: Non‐clinical setting How administered: Self‐administered Format of PROMs questionnaire(s): Paper, or via telephone system Feedback features Format of PROMs feedback: Paper How often information fed back: At intake and at 6 weeks Who information fed back to: Clinicians Information fed back: Scores, Previous scores, Interpretation guidance |

| Outcomes | Main outcomes: depression (SCL‐11), anxiety (SCL‐11) Other outcomes: clinician satisfaction | |
| Notes | National Institute of Mental Health grant (1 R43MH57614‐O1 A1). The study period was not reported. No conflicts of interest were reported. | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Randomisation method not stated. |
| Allocation concealment (selection bias) | Unclear risk | Not clear as randomisation method was not discussed |
| Blinding of participants and personnel (performance bias) All outcomes | High risk | Not possible due to study design (crossed design; study looking at feedback). |
| Blinding of outcome assessment (detection bias) All outcomes | High risk | Due to nature of the intervention blinding of outcomes not possible: PROM used for feedback also used to assess outcome, patients were aware they received the intervention. |
| Baseline outcome measurements similar | Low risk | None apparent |
| Baseline characteristics similar | Low risk | None apparent |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | None apparent |
| Was study protected against contamination | Unclear risk | Unclear as the patients were contacted via telephone or post |
| Selective reporting (reporting bias) | Unclear risk | Outcome measurements collected were reported |
