The scale consists of 18 items across four dimensions and assesses nursing students' creativity, confidence, awareness, and neutrality when facing ethical decision-making dilemmas involving patients or their families. It is based on Rest's Four-Component Model of Ethical Decision-Making, comprising ethical judgment, ethical sensitivity, ethical motivation, and ethical action. Each item is rated on a 5-point Likert scale ranging from 0 (strongly disagree) to 4 (strongly agree). The total score ranges from 0 to 72, with higher scores indicating a higher level of ethical decision-making competence.

The scale consists of three dimensions: compassion satisfaction (CS), burnout (BO), and secondary traumatic stress (STS). CS represents a positive aspect, whereas BO and STS represent negative aspects. Items are rated on a 5-point Likert scale ranging from 1 ("never") to 5 ("always"). The cutoff scores for CS, BO, and STS are 27, and \>17, respectively. Compassion fatigue severity is classified as mild when one dimension exceeds its cutoff, moderate when two dimensions exceed their cutoffs, and severe when all three dimensions exceed their cutoffs.
