NCT07249723

Brief Summary

This study was conducted to compare the effects of two active distraction methods-bubble blowing and a material-free cognitive distraction/positive reinforcement technique-applied during venous blood sampling on pain, fear, and anxiety levels in children aged 7-12 years.

Outcome Measures

Primary Outcomes (2)

  • Wong-Baker FACES Pain Rating Scale (WB-FACES)

    Developed by Wong and Baker (1988), this scale assesses pain intensity in children aged 3-18 years based on facial expressions, using a 0-5 scoring system. Pain intensity was assessed using the Wong-Baker FACES Pain Rating Scale (0-10; higher scores indicate worse pain).

    A total of 2 evaluations will be made: before the procedure starts, the post-test immediately after the end of the procedure.

  • Children's Fear and Anxiety Scale (CFS)

    Developed by McMurtry et al. (2011) and adapted into Turkish by Gerçeker et al. (2018), this scale evaluates fear and anxiety during the procedure on a 0-4 rating scale. 0-10; higher scores indicate greater fear and anxiety.

    A total of 2 evaluations will be made: before the procedure starts, the post-test immediately after the end of the procedure.

Secondary Outcomes (1)

  • Visual Analog Scale (VAS)

    A total of 2 evaluations will be made: before the procedure starts, the post-test immediately after the end of the procedure.

Study Arms (3)

Bubble Blowing Group

EXPERIMENTAL

Before the procedure, each child was given a bubble toy and instructed to blow bubbles throughout the procedure. The procedure duration was recorded with a stopwatch. Post-procedural pain and anxiety were assessed using standardized scales. A single-use bubble toy was used for each child.

Other: Bubble Blowing Group

Positive Reinforcement Group

EXPERIMENTAL

Before the procedure, the researcher established communication with the child, and a short cognitive activity chosen by the child (e.g., counting numbers, word game) was implemented throughout the procedure. The parent provided physical and verbal support to the child. After the procedure, the child received verbal positive reinforcement.

Other: Positive Reinforcement Group

Standard Procedure Blood Sampling Group

NO INTERVENTION

Children in the control group underwent the standard blood sampling procedure in accordance with routine clinical practice. Outcome measurements were conducted after the procedure. Once data collection was completed, children in this group also received verbal feedback. All measurements were performed immediately before and after venipuncture. A single-needle insertion technique was used, and all blood draws were performed by the same pediatric nurse, who was permanently assigned to the unit, to ensure procedural standardization.

Interventions

In the Positive Reinforcement Group, children performed a non-material cognitive activity of their choice during the procedure (such as counting, reciting a short poem/song, or a word game). At the end of the procedure, verbal positive reinforcement was provided (e.g., "Well done," "You were very brave").

Positive Reinforcement Group

In the Bubble Blowing Group, children were given a bubble toy during the procedure and asked to blow bubbles. This method, which requires active motor participation, was used to divert the children's attention away from the stress of the procedure.
