Variable | Construct | Scale/measure | Measurement | Scoring | Reliability | Validity |
---|---|---|---|---|---|---|
Independent | 1. Resonant leadership | Resonant leadership scale (Estabrooks et al., 2009) | 10 items measuring components of resonant leadership | Likert scale (1–5) for each item. Means of those who answered (1)– (5) used as resonant leadership score | High internal consistency for total scale α = 0.95 |
Face/content validity Correlations between variables above 0.5, most above 0.6. |
Independent | 2. Leader–member exchange | Leader–member Exchange (LMX‐7) Graen and Uhl‐Bien (1995) | 7 items measuring the satisfaction of employees with their relationship with their supervisor | Likert scale (1–5) for each item | Internal consistency from the member's perspective (α = 0.89) | Reported to have predictive validity |
Independent | 3. Perceived Organisation Support | Perception of Organisational Support (POS) (Eisenberger et al., 1997) | 8 items measuring perception of organizational support | Likert scale (7–1) for each item | High internal reliability α = 0.90 and goodness of fit α = 0.94 | Reported to have discriminant validity |
Independent | 4. Work Engagement | Utrecht Work Engagement Scale (UWES) (Schaufeli et al., 2006) | 9 items measuring three factors of work engagement; vigour, dedication, and absorption | Likert scale (0–6) for each item | High internal reliability α = 0.89–0.97 | Factorial validity variances between countries for and internal consistency (α = 0.60 to 0.88, respectively, median = 0.77). |
Dependant | 5. Perception of unit care quality | Perceptions of unit care quality Aiken et al. (2001) and Aiken et al. (2002) | 4 items measuring perceptions of care on their unit | Likert scale (1–4) for 3 items and 1–3 for 1 item | Not reported | |
Marker | 6. Willingness to try new food products DSI | Willingness to try new food products; DSI scale Goldsmith and Hofacker (1991) adapted by Barcellos et al. (2009) | 6 items | Likert scale (1–5) for each item | Good reliability in Brazil (α = 0.80) and in the UK (α = 0.78). | Reported to have predictive validity |
Dependant | 7. Patient safety | Falls (Purdy et al., 2010) | Number of falls recorded by the institution | Number per 1,000 bed days | ||
Dependant | 8. Patient satisfaction | Friends and Family Test (Department of Health, 2013). | 1 item measuring likelihood to recommend for similar care or treatment | Percentage of promoters (score 5) over detractors (scores 1 & 2) across a 5‐point scale. |
