The purpose of this study is to adapt the Principal Emotion Inventory (PEI) developed by Junjun Chen, which measures the emotions experienced by school administrators in various situations, to Turkish culture and to assess the scale's psychometric qualities. There were 305 school principals in the research group, representing various school levels (preschool, primary school, secondary school and high school). Various analyses were conducted to provide evidence for the validity and reliability of the measurement tool. In line with the findings of the construct validity confirmatory factor analysis, it was determined that eight of the goodness-of-fit indices showed acceptable fit and three of them revealed excellent fit. It was confirmed that the Turkish form validated the five-dimensional structure of the original 25-item PEI. Factor loadings ranged from 0.32 to 0.72 in the Enjoyment sub-dimension; 0.42 to 0.69 in the Pride sub-dimension; 0.59 to 0.79 in the Frustration subdimension; 0.55 to 0.69 in the Anxiety sub-dimension; and 0.49 to 0.77 in the Hopelessness sub-dimension. In order to provide evidence of reliability, Mcdonald Omega was calculated utilizing factor loadings and specific variances in addition to Cronbach Alpha coefficient. The Omega coefficients calculated for the five sub-dimensions were 0.45 (Enjoyment), 0.72 (Pride), 0.82 (Frustration), 0.77 (Anxiety) and 0.83 (Hopelessness), respectively. The Cronbach Alpha coefficients calculated for the five sub-dimensions were 0.54, 0.71, 0.82, 0.77 and 0.83, respectively. The scale is a valid and reliable measuring tool that may be used to ascertain school principals' feelings regarding the situations they encounter, as demonstrated by all of these analysis findings.
