This study aims to develop a scale to measure people's attitudes towards cancer screening and conduct a pilot study and validity-reliability study of the developed scale.

RESULTSThe study group of 334 participants consisted of 50% males and 50% females, and the mean age was 42.93±9.60years.Four items with item score-scale score correlation less than ±0.200 were excluded from the 28-item candidate scale.Cronbach's alpha coefficient of the 24-item scale was calculated as 0.95.Face and content validity of the scale was evaluated with two different groups.Factor analysis that was used to assess the construct validity of the one-dimensional 24-item scale determined that explained the variance ratio was 52.62%.
