2. objects (30): vignettes of 30 psychiatric inpatients each of which consisted of the patient’s sex and age, a short description by the patient of his/her problem, and observational data from a nurse of the patient’s ward
3. variables (36):
3.1 technical variables (2): 1. number of clinician 2. number of vignette
3.2 internal variables (23): supposed presence of psychiatric symptoms
3.2.1 The first 19 internal variables were taken from the Psychiatric Evaluation Form (Endicott & Spitzer, 1972): 3. speech disorganization 4. agitation - excitement 5. hallucinations 6. inappropriate 7. disorientation - memory 8. depression 9. anxiety 10. suicide - self-mutilation 11. somatic concerns 12. narcotics - drugs 13. antisocial 14. retardation - lack of emotion 15. social isolation 16. daily routine - leisure time 17. alcohol abuse 18. belligerence - negativism 19. denial of illness 20. grandiosity 21. suspicion - persecution
3.2.2 The final 4 internal variables pertained to the supposed presence of several forms of impairment: 22. intellectual impairment 23. impulse control 24. social blunting 25. role impairment
3.3 external variables (11): All of these pertained to diagnostic judgements with regard to four overarching DSM-III Axis 1 categories.
3.3.1 overall measures (3): 26. certainty about diagnosis (diagnoses) 27. extent to which your set of DSM-III diagnoses correctly reflect the supposed problem of the patient 28. extent to which vignette includes sufficient information to make a diagnosis
3.3.2 specific measures (8): 29. supposed applicability of substance use disorder 30. certainty about preceding applicability judgement 31. supposed applicability of schizophrenic disorder 32. certainty about preceding applicability judgement 33. supposed applicability of depressive affective disorder 34. certainty about preceding applicability judgement 35. supposed applicability of anxiety disorder 36. certainty about preceding applicability judgement
2. internal variables: symptoms 3-25: 0 (absent) - 1 (present, in part or in whole, to a small or a to large extent)
3. external variables: 26: whole number between 0 (very uncertain) and 9 (very certain); 27: whole number between 0 (very bad reflection) and 9 (very good reflection); 28: whole number between 0 (big lack of information) and 9 (fully sufficient information); 29,31,33,35: 0 (not applicable) - 1 (applicable); 30,32,34,36: whole number between 0 (very uncertain) and 9 (very certain)
