The interaction was evaluated between gender, survey format, and item sensitivity level.
Both leverage and salience may vary with the method of data collection and interact with other attributes of the survey (for example, item sensitivity).
To validate our methodology a pilot study with 17 participants was conducted, which demonstrated the methods to be feasible and acceptable with no issues regarding item sensitivity and cultural inappropriateness [ 32].
An extra appraisal item, 'Sensitivity of outcome tool' was added to the published tool since the use of an insensitive outcome tool may have meant that differences in posture between conditions were not measured, significantly impacting on study outcomes [ 28].
The scale comprises 8 sub-scales on: Handling Disagreement & Conflict (9 items); Internal Work Motivation (8 items); Control over Practice (5 items); Leadership and Autonomy in Clinical Practice (5 items); Staff Relationships with physicians (2 items); Teamwork (4 items); Cultural Sensitivity (3 items); Communication about patients (3 items).
The nine subscales that can be derived from the SCL-90-R are: somatization (SOM, 12 items), obsessive-compulsive (OBS, 10 items), interpersonal sensitivity (SENS, 9 items), depression (DEP, 13 items), anxiety (ANX, 10 items), anger-hostility (HOS, 6 items), phobic anxiety (PHOB, 7 items), paranoid ideation (PAR, 6 items) and psychoticism (PSYC, 10 items).
When using the general health item, the sensitivity and specificity in model D (sensitivity 0.52 and specificity 0.81) were similar to those in model A (0.45 and 0.80).
We also examined alternative binary definitions of this item in sensitivity analysis.
Feedback and comments provided by participants related to clarity of instructions, repetition of some items, irrelevancy of items, length of questions, similarity of items and sensitivity of questions such as income.
We also found that the level of alertness and fluctuation items drove specificity to delirium, while the AMT4 (orientation) and Months Backwards (attention) items drove sensitivity to delirium.
Care (12 items) assesses sensitivity, warmth, emotional responsiveness, trust, physical gentleness and kindness.
