Validity and Reliability of The Turkish Version of The Solid Waste Management Scale in Health Institutions

Aim: This research was conducted with the aim to determine the validity and reliability of the
Turkish version of the Solid Waste Management Scale in health institutions.
Method: The study population consisted of nurses working in two different hospitals (918
+ 939 = 1857 nurses). The samples were selected from the universe using the improbable
sampling method. The data were collected by a Personal Information Form and the Solid
Waste Management Scale in Healthcare Institutions. The data were analyzed based on
the computations of descriptive statistics including mean, standard deviation, frequencies,
percentages, Cronbach’s alpha reliability coefficient, Pearson Product Moments Correlation,
Factor Analysis, Bartlett’s Test, and Kaiser-Meyer-Olkin Test.
Results: The content validity index of the scale was found to be 0.98. The Cronbach’s alpha
reliability coefficients of the scale ranged between 0.59, and 0.73, while the item factor loads
between 0.31, and 0.94, and the item-total correlation values between 0.21, and 0.77. The
factorial structure of the scale was confirmed as a result of the Exploratory and Confirmatory
Factor Analyses.
Conclusion: The Turkish version of the Solid Waste Management Scale in Health Institutions
showed that it is a valid and reliable tool for determining the level of knowledge and attitudes of
nurses working in health institutions about solid waste management. This scale, whose validity
and reliability has been tested, can be used to determine the attitudes and knowledge levels of
nurses working in health institutions on solid waste management.
