Development of Performance Evaluation Scale for
Forest Engineers Using Confirmatory Factor Analysis Method
Managers of forest enterprises, as managers of many
other enterprises and organizations want to know the performance levels
of their employees. For this reason, many enterprises use various
methods to determine the performance levels. The primary purpose of this
study is to develop a Performance Evaluation Scale (PES) in order to
determine the performances of the forest engineers who are currently
working at the forest enterprises in Aegean Region, and then to
investigate the validity and reliability of the scale. This study was
conducted within the 23 forest enterprises of Denizli, Izmir and Mugla
Forest Regional Directorates in the Aegean region of Turkey. A total of
52 criteria were determined for performance evaluation as a result of
focus group meetings and individual interviews conducted with the
experienced forest engineers. These criteria were scored by 85 forest
engineers by using a questionnaire designed according to the nine-grade
Likert scale. Appropriateness of the data was evaluated via the t test,
the Bartlett Sphericity test and the Kaiser-Meyer-Olkin (KMO) test. Then,
the data were converted into the factors which are less and significant
and independent of each other, with explanatory factor analysis method.
Thus, the six factors describing 68.67% of the total variance were
obtained. Each of the factors was named according to the factor loads
and the criteria and then, the scale was formed. Finally, confirmatory
factor analysis was performed and five-factor structures with an
acceptable level of goodness of fit indices were created.
Key words: Aegean region, confirmatory factor analysis (CFA),
forest engineer, performance evaluation scale, Turkey.
