Peripheral venous catheterization, which involves the placement of an invasive device into the lumen of a peripheral vein, is a commonly used procedure in children receiving hospital treatment.IV insertion is a particularly painful and stressful experience for children. This is because children have more limited coping skills than adults. This study was designed as a randomized controlled trial to examine the effect of sticker intervention on pain and anxiety experienced during IV insertion.

The study consists of an sticker group and a control group. Participants will be assigned to groups using stratified randomization. Anxiety levels in both groups will be assessed using the Children's Anxiety Scale-State (ÇAS-D), while pain levels will be evaluated by both the child and the researcher using a visual pain scale before, during, and after the procedure.For children in both groups, 10 minutes before the intravenous procedure, both the child and the researcher will rate the child's anxiety and pain using scales.During the IV procedure, the researcher will place the sticker chosen by the child on the IV insertion site. Meanwhile, the researcher will rate the child's anxiety and pain using scales. No sticker will be placed on the IV insertion site of the control group, and the child's anxiety and pain will be rated using scales.For both groups, 10 minutes after the intravenous procedure, both the child and the researcher will rate the child's anxiety and pain using scales.

Inclusion Criteria:

• Children aged 5-10 years,
