Design outcomes

Primary

MeasureTime frame
1. Competence is measured using a Self-Assessment Questionnaire (M-SQ) following two working shifts (T1 - T2) 2. Hydration status is measured using self-assessed urinalysis reagent Labstick’s reporting urine specific gravity (Uspecific gravity) at T1 and T2

Secondary

MeasureTime frame
Current secondary outcome measures as of 01/03/2021: Measured at B0: 1. The Professional Quality of Life – Version 5 (ProQOL-5) to assess coping competence, burnout, secondary traumatic stress and compassion satisfaction (Stamm, 2009) 2. The Profile of Emotional Competence (PEC) as a self-reported measure of intra- and inter-personal emotional competence and global emotional intelligence (Brasseur, Grégoire, Bourdu, & Mikolajczak, 2013) 3. The Almost Perfect Scale-Revised Short Form (APS-R SF) to assess attitudes towards others, themselves and their performance, orthogonally measuring the maladaptive and adaptive aspects of perfectionism (Slaney et al., 2001) 4. The Diagnostic Thinking Inventory (DTI) which is a widely applied self-assessment tool used to determine clinical diagnostic reasoning in doctors at all stages of their career. The DTI assesses two clinical reasoning domains: knowledge structure in memory and flexibility in thinking (Bordage, Grant & Marsden, 1990)5. The Lifestyle Appraisal Questionnaire (LAQ) as a comprehensive assessment of lifestyle (Craig, Hancock & Craig, 1996) Measured at T1 and T2: 5. The Daily Stress Inventory (DSI) items measure a 24-hour period and three daily scores are derived on the number of events, the sum of the impact of the events, and the average impact rating of the events (Brantley, Waggoner, Jones & Rappaport, 1987) 6. N-back Letters Tasks (level 2 and 3), tasks will be used as a cognitive assessment to measure performance of a part of working memory and working memory capacity 7. Reagent Labstick’s: urinary pH (UpH) as a measure of physiologic and psychological stress 8. Urine colour (Ucolour) will be analysed using an NHS 8-level colour chart 9. Fluid record based on the volume and type of fluid consumed over the duration of their working shif
