| Study characteristics | |||
| Patient Sampling | Participants were recruited as part of a study investigating the reliability and validity of the Canberra Interview for the Elderly (CIE); recruited as a consecutive series. An additional non‐consecutive group were recruited elsewhere (principally psychogeriatricians) | ||
| Patient characteristics and setting | Patients were a series of those assessed by geriatricians as inpatients, day‐hospital attenders or outpatient clinic attenders (n = 64). As the authors were interested in assessing the score in depression, they also recruited a subgroup of patients, principally via psychogeriatricians (n = 12). Study conducted in Canberra Australia | ||
| Index tests | IQCODE 26 item, English language | ||
| Target condition and reference standard(s) | Clinical dementia diagnosis using DSM‐III‐R and ICD‐10 | ||
| Flow and timing | Of 72 potential participants from the geriatric settings 64 agreed to participate. 12 patients were recruited from other sources. Of the 76 potential participants, 7 were excluded due to missing data (index test or MMSE) so total sample was 69. Reference standard determined by the treating clinician. Index test administered by lay interviewers at an interval afterwards. Unclear if this was blinded to clinical diagnosis. Further index test assessment performed to assess test‐retest reliability |

| Item | Authors' judgement | Risk of bias | Applicability concerns |
| DOMAIN 1: Patient Selection | |||
| Was a consecutive or random sample of patients enrolled? | No | ||
| Was a case‐control design avoided? | Yes | ||
| Did the study avoid inappropriate exclusions? | Yes | ||
| Could the selection of patients have introduced bias? | High risk | ||
| Are there concerns that the included patients and setting do not match the review question? | High | ||
| DOMAIN 3: Reference Standard | |||
| Is the reference standards likely to correctly classify the target condition? | Yes | ||
| Could the reference standard, its conduct, or its interpretation have introduced bias? | Low risk | ||
| Are there concerns that the target condition as defined by the reference standard does not match the question? | Low concern | ||
| DOMAIN 4: Flow and Timing | |||
| Was there an appropriate interval between index test and reference standard? | Unclear | ||
| Were all patients included in the analysis? | Unclear | ||
| Could the patient flow have introduced bias? | High risk | ||
