Social Robot Interaction on Fear and Pain Levels in Children

June 7, 2026 updated by: Remziye Semerci, Trakya University

The Effect of Social Robot Interaction on Fear and Pain Levels in Children During Venous Blood Sampling: A Randomized Controlled Study

The goal of this clinical trial is to compare the effectiveness of social robot interaction and digital game-based distraction in reducing fear and pain during venous blood sampling in children aged 4-12 years with chronic diseases.

The main questions it aims to answer are:

  • Does social robot interaction reduce procedural fear and pain more effectively than standard care during venous blood sampling?
  • Does social robot interaction provide greater emotional recovery after the procedure compared with digital game-based distraction and standard care? Researchers will compare a social robot intervention group, a digital game-based distraction group, and a standard care group to determine their effects on children's fear and pain levels before, during, and after venous blood sampling.

Participants will:

  • Be randomly assigned to one of three groups: social robot, digital game, or standard care.
  • Complete fear and pain assessments 5 minutes before, during, and 5 minutes after the venous blood sampling procedure.
  • Interact with a social robot or play a digital game before and during the procedure if assigned to one of the intervention groups.
  • Receive routine clinical care if assigned to the standard care group. The study aims to provide evidence on the effectiveness of technology-based distraction methods for reducing procedural distress and improving the procedural experience of children undergoing venous blood sampling.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control Group
Experimental: social robot
Other: Social Robot
Children interacted with an interactive social robot for approximately 5 minutes before venous blood sampling and throughout the procedure. The robot provided age-appropriate storytelling, songs, verbal communication, movement-based interaction, and visual stimulation to distract children and reduce procedural fear and pain.
Experimental: digital game
Other: Digital Game
Children received a digital game-based distraction intervention using the Bubble Rainbow application. Participants were allowed to familiarize themselves with the game for approximately 5 minutes before venous blood sampling. During the procedure, children continued playing the game on a tablet device while receiving support from their parents. The game included interactive activities such as bubble popping, color matching, and visual attention tasks designed to engage the child's attention and reduce procedural fear and pain.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Wong-Baker Faces Pain Rating Scale
Time Frame: Pain was assessed 5 minutes before venous blood sampling, during the procedure, and 5 minutes after the procedure.
Procedural pain was assessed using the Wong-Baker FACES Pain Rating Scale. The scale consists of six facial expressions scored from 0 (no pain) to 10 (worst pain), with higher scores indicating greater pain intensity
Pain was assessed 5 minutes before venous blood sampling, during the procedure, and 5 minutes after the procedure.
Children Fear Scale
Time Frame: Fear was assessed 5 minutes before venous blood sampling, during the procedure, and 5 minutes after the procedure.
Procedural fear was assessed using the Scary Scale, a self-report instrument designed for children aged 4-12 years. The scale consists of six facial expressions scored from 0 (no fear) to 10 (highest fear), with higher scores indicating greater fear levels.
Fear was assessed 5 minutes before venous blood sampling, during the procedure, and 5 minutes after the procedure.
