The hypothesized serial multiple mediation model with three mediators (M1 = desire for improvement, M2 = reflective capacity, M3 = confidence) representing eight distinct effects of practicum experiences (X) on positive mirror effect (Y), one direct and seven indirect. Direct effect H1: X → Y = C’; three indirect effects of X on Y through one mediator (H2: X → M1 → Y = a1b1; H3: X → M2 → Y = a2b2; H4: X → M3 → Y = a3b3); three indirect effects of X on Y through two mediators in serial (H5: X → M1 → M2 → Y = a1d21b2; H6: X → M1 → M3 → Y = a1d31b3; H7: X → M2 → M3 → Y = a2d32b3), and one through all three mediators in serial (H8: X → M1 → M2 → M3 → Y = a1 d21d32b3).
