The diagnoses obtained through different models of diagnostic interviews (history taking) in psychiatry will be evaluated and compared. Such interviews will be evaluated as diagnostic tools and compared against LEAD (Longitudinal, Expert, All Data) obtained by an experienced psychiatrist. The following interviews will be studied: Free style interview (non-structured), semi-structured interview (“Standard for Clinicians' Interview in Psychiatry" - SCIP, with McGill MINI - Narrative experiences of

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We expect to show that the diagnoses proposed by the examiner change according to the interview model used in the same patient. For this purpose, the kappa agreement values will be measured for the diagnoses obtained for the following comparisons: Free vs structured interview; Free vs Semi structured interview; Structured interview vs semi structured interview. The sample was calculated taking into account the possibility of the occurrence of 17 diagnoses, predicting an average effect size (w = 0.3), which we hope to detect or reach enough power to discard. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome will be the assessment of the sensitivity and specificity of the Free, Structured and Semi-structured Interview compared to the gold standard. The calculation will be carried out through double entry contingency tables, using the formulas of sensitivity (true positive / true positive + false negative) and specificity (true negative / true negative + false positive). We hope to find increased sensitivity with the use of systematic interviews (structured and semi-structured) and greater specificity with the clinical freedom to investigate the patient (semi-structured and free). The results will be used to construct the ROC curve in order to evaluate the interviews as diagnostic methods. We believe that the free interview will present the worst overall performance, followed by structured interviews, with semi-structured interviews showing the best results. | — |
