Note. PU = perceived usefulness; PEOU = perceived ease of use; ATT = attitude toward using PHR; INT = intention to use PHR; HTSE = health-care technology self-efficacy.

Diagonal in Bold: square root of the average variance extracted (AVE) from observed items; Off-diagonal: correlations between constructs. *p < 0.05; **p < 0.01
