Dummy variables were coded 0 for female and 1 for male (sex); 0 for diploma or associate degree and 1 for bachelor’s or master’s degree (educational level); 0 for staff nurse and 1 for charge or assistant head nurse (position); 0 for none and 1 for certified nurse (advanced practice certification); 0 for no and 1 for yes (participation in nursing informatics education); 0 for non-positive [not positive, not very positive, or neither positive nor negative] and 1 for positive [moderately positive or positive] (attitudes toward using digital devices at work); 0 for non-confident [not confident, not very confident, or neither confident nor unconfident] and 1 for confident [moderately confident or confident] (confidence in using digital devices at work).

R2 = 0.339; adjusted R2 = 0.281.

a: Digital health literacy was measured using the Japanese version of the Digital Health Literacy Instrument. The digital health literacy score ranges from 1 to 4, with higher scores indicating greater digital health literacy.

b: Nursing informatics competency was measured using the Japanese version of the Nursing Informatics Competency Scale. The total score for this scale ranges from 22 to 88, with higher scores indicating greater nursing informatics competency.

c: The number of years of experience as a clinical nurse was log-transformed before being included in the regression model.

β: standardized coefficient; B: unstandardized coefficient; CI: confidence interval; VIF: variance inflation factor.
