Item factor loading based on principal component analysis with varimax rotation of RDQ-13 scale.
| Factors | CR | AVE | |||
|---|---|---|---|---|---|
| 1 | 2 | 3 | |||
| Attitude score | 0.666 | 0.764 | 0.520 | ||
| Perception score | 0.732 | ||||
| Domain1: Related to renal dose adjustment | 0.763 | ||||
| Domain 2: Factors to be considered when determining the appropriate dose for a patient with renal impairment | 0.751 | 0.517 | 0.762 | ||
| Domain 3: Medications commonly require renal dose adjustment | 0.708 | ||||
| Domain 6: Resources to determine the appropriate dose for a patient with renal impairment | 0.697 | ||||
| Domain 4: Calculating the appropriate dose for a patient with renal impairment | 0.796 | 0.641 | 0.479 | ||
| Domain 5: Consequences of not adjusting the dose of medications for patients with renal impairment | 0.569 | ||||
Extraction method: principal component analysis. Rotated method: varimax. Domain 1 to 6 are related to knowledge score. The sequence of domains is not in flow because it is based on the loading factors, its CR and AVE.
Abbreviations: AVE = average variance extracted, CR = composite reliability.
