The control group will receive routine clinical care. No intervention will be made.

Before the circumcision, children will be shown a video animation show and will be made to play games with health riddles and normal riddle books.

The distribution of the participating children to the experimental and control groups will be carried out by simple random sampling method. Children included in the Normal Riddle Book group will be introduced to a book containing general, entertaining riddles that are not related to health during the pre-circumcision period.

The book will be given to the children approximately 1 hour before the circumcision operation and the children will be allowed to read the puzzles, solve them or interact with the researcher/nurse. The application period is planned as approximately 20-30 minutes.

The children's fear, anxiety and pain levels will be measured before and after the application. During the application process, the children's attention level, interest in the book and general behavior will be observed and recorded.

The introductory information form prepared by the researchers consists of items related to the child's age, gender, height, weight, place of residence, number of siblings, previous hospitalization, previous surgery, mother's age, education status, father's age, education status and the family's economic status.

This scale was developed by McMurtry and colleagues in 2011 and was adapted to Turkish by Gerçeker and his team in 2018 and validated. Designed for children between the ages of 5 and 10, this scale presents facial muscle changes in fearful expressions with a graphic artist's drawings based on photographs of frightened faces. The scale can be used by the family, child, or researcher to evaluate children. The scale shows the child a scale containing five facial expressions scored between 0 and 4. These expressions are interpreted as follows: 0: Neutral expression (no fear), 1: Very little fear, 2: Some fear, 3: More fear, 4: Highest level of fear. This scale can be used to measure the child's level of fear before and during the procedure.

The "Child Anxiety Scale-State" (CAS-D) scale, developed by Ersig and his colleagues in 2013, is used to measure the situational anxiety of children between the ages of 4-10. Its validity was provided by Gerçeker and his team in 2018. CAS-D is designed in the shape of a thermometer and has a bulb chamber at the bottom and horizontal lines upwards. Each horizontal line represents one point, and there are 10 points in total. The bottom line represents a score of 0 and indicates a situation where there is no anxiety. The anxiety level increases as you go higher, and the top line represents the highest anxiety with a score of 10.

The Wong-Baker Faces Pain Rating Scale is an adaptation of the Faces Rating Scale, a picture projection technique that uses 6 pictures of a child's facial expressions in pain to assess the child's level of pain. This scale is used to best describe the child's current level of pain.

The child is asked to choose the face that best describes their pain. The descriptions of the faces are as follows:

Face 0: Depicts a painless, happy face, meaning "I'm very happy, I'm in no pain." Face 5: Depicts a crying face, meaning "it hurts as much as you can imagine, but you don't have to cry to feel that bad." The responses on this 5-point scale range from 0 (very happy, no pain) to 5 (it hurts as much as you can imagine) and help determine the child's level of pain.
