Table 6. One-way ANOVA for the five factors of HS-EBP questionnaire and the four levels of training in EBP.

	Level of training in EBP
	No training in EBP Mean (SD)	Basic^a Mean (SD)	Intermediate^b Mean (SD)	Advanced^c Mean (SD)
Beliefs–Attitudes (D1)	97.39 (15.77)^AB	101.20 (14.63)	101.80 (11.34)^A	103.74 (12.20)^B
Results from scientific research (D2)	91.48 (24.80)^AB	91.32 (24.08)^C	97.09 (20.93)^AD	111.00 (18.09)^BCD
Professional practice development (D3)	77.09 (11.78)^A	76.72 (12.98)	78.03 (10.04)	80.10 (11.36)^A
Assessment of results (D4)	83.79 (20.21)^A	85.40 (22.14)	85.66 (19.60)	90.16 (19.58)^A
Barriers/ Facilitators (D5)	63.72 (22.90)^A	66.35 (22.98)	64.19 (19.90)^B	71.80 (23.27)^AB

Note: Within the same dimension, the levels of training in EBP with the same superscript (i.e. “A”, “B”, “C” and/or “D”) are significantly different from a statistical point of view. In all cases the difference is significant with p<0.05.

^a Basic training: understood as having done an/some introductory course/s to EBP, bibliographic search in electronic databases or similar.

^b Intermediate training: understood as, in addition to the above, also having done a/some introductory course/s to research methodology: asking a research quesiton, critical reading of scientific articles, interpretation of statistical results, or similar.

^c Advanced training: understood as, in addition to the above, also having done a/some training course/s on research: statistics and handling computer programmes e.g.: SPSS, R, Stata; writing scientific articles, or similar.
