Objective:

Validate scale to measure pedagogical knowledge of the nursing mentor in conducting practices.

Methods:

Methodological, quantitative study, period 2019-2020. From the theoretical construct and qualitative study, reagents arise, submitted to expert consensus for content validity. The scale was administered to a universe of N=172 clinical mentors. For interrater agreement of the scale, statistical coefficients were used. Reliability was achieved by Cronbach's Alpha. Construct validity was by exploratory factor analysis.

Results:

Interjudge agreement obtained high internal consistency; item with correlation <0.5 were eliminated, significant item were incorporated, p> 0.05. The final version of the scale had 33 item, with Cronbach's score of .897. The exploratory factorial analysis explained 74% of the total variance, contributing four factors.

Conclusions:

The scale has validity and reliability, propitious diagnosis of pedagogical knowledge of mentors to conduct nursing practices.
