Abstract
Background
Cancer screening is an important component in the struggle against cancer-induced morbidity and mortality. The aim of the study was to develop a scale that will measure the knowledge about cancer screening and will be used in the Turkish society.
Methods
The research is a scale development (validity and reliability) study. A total of 265 men and women between the ages of 18-70 are included in the study. The data collection form used in the study comprises two parts. It is a 15-item questionnaire on sociodemographic characteristics form and a candidate scale with 28 items.
Results
The mean age of the participants was 41 years; 50.9% (n=135) were female. The face and content validity of the scale were done by two different teams. Item score-scale score correlation <0.20 in 1 item out of 28 items. During the structural factor analysis, 2 items with a factor load of <0.30 were excluded from the scale. The Cronbach’s alpha coefficient of the 25-item scale was calculated 0.89. The explained variance of the scale was 41.8%.
Conclusion
As a result of the research, a new scale called ‘Knowledge Scale for Cancer Screening’ is developed, comprising 25 items and 3 sub-dimensions.
