Purpose: This study was conducted to determine the effect of an online educational intervention on migrant women's knowledge and attitudes toward cancer screening.
DesigN:This study was designed as a two-arm, parallel-group, randomized controlled trial with pre-test and post-test assessments.
Method: The study population will consist of women registered at the Cancer Early Diagnosis, Screening and Training Center (KETEM) affiliated with the Erzincan Provincial Health Directorate. The sample size was calculated based on a two-group (intervention and control) and two-measurement (pre-test and post-test) study design. Using repeated-measures ANOVA with a medium effect size (d = 0.25), a significance level of 5% (α = 0.05), and a statistical power of 80% (1 - β = 0.80), the required sample size was determined to be 34 participants per group (34 in the intervention group and 34 in the control group), resulting in a minimum total sample of 68 participants. To account for potential attrition, it was planned to recruit 80 participants (approximately 20% more than the minimum required sample size).
