Mean scores in the MBI subscales

MBI subscale	Mean ± sd	Low (95%CI)	Moderate (95%CI)	High (95%CI)
EE	16.55 ± 9.09	69.60 (62.38-76.74)	22.42 (15.85-28.86)	8.15 (3.82-12.32)
PA	5.20 ± 4.61	42.23 (34.52-49.94)	34.83 (27.34-42.21)	23,01 (16.41-29.54)
DP	39.50 ± 5.58	59.02 (51.32-66.68)	23.60 (16.97-30.23)	17.39 (11.47-23.30)

The 95%CI have been calculated using the binomial Wald assumption

EE: high (≥ 31), moderate (21-30), low (≤ 20)

PA: high (≤ 35), moderate (41-36), low (≥ 42)

DP: high (≥ 11), moderate (6-10), low (≤ 5)
