Effect of Buzzy®, Cognitive Behavioral Intervention, and Kaleidoscope During SC Injection in Children With Cancer
A study testing Cognitive Behavioral Intervention Package Group, Buzzy® Group and Kaleidoscope Group in people with Pediatric Cancer and Procedural Pain, run by Kocaeli University at 1 site in Turkey (Türkiye).
Trial summary
Subcutaneous injections are commonly used in pediatric oncology care and may cause pain, fear, and anxiety in children. Repeated exposure to needle-related procedures may increase procedural distress and affect children's cooperation and coping during treatment. Read more about this study

About this study
Official title: Buzzy®, a Cognitive-Behavioral Intervention Package, and a Kaleidoscope for Reducing Pain, Fear, and Anxiety During Subcutaneous Injections in Children With Cancer: A Three-Arm Randomized Controlled Trial
Subcutaneous injections are commonly used in pediatric oncology care and may cause pain, fear, and anxiety in children. Repeated exposure to needle-related procedures may increase procedural distress and affect children's cooperation and coping during treatment. Therefore, simple, safe, and feasible non-pharmacological interventions are needed to improve children's comfort during routine procedures.
This randomized parallel trial was designed to compare three clinically feasible non-pharmacological approaches with different mechanisms during subcutaneous injections in children with cancer. Buzzy® provides cold and vibration as a sensory-based method, the cognitive behavioral intervention package supports preparation and coping, and the kaleidoscope provides visual distraction. By comparing these approaches within the same procedural context, the study aimed to provide practical evidence for pediatric oncology nurses when selecting interventions to reduce procedural distress.
All procedures were conducted in the routine clinical procedure area of a pediatric oncology clinic. The same subcutaneous injection procedure was used for all participants, and standardized assessment time points were applied before and immediately after the procedure.
Read the detailed description
This study was conducted as a randomized, parallel-group clinical trial in children with cancer undergoing routine subcutaneous injection. Participants were assigned to one of three intervention groups: Buzzy®, a cognitive-behavioral intervention package, or kaleidoscope distraction.
All interventions were delivered in the same clinical setting and within the same procedural context. Before the injection, baseline levels of procedural fear and state anxiety were assessed. The assigned intervention was then applied according to the group allocation during the subcutaneous injection procedure. Pain, fear, and state anxiety were evaluated immediately after the procedure using standardized pediatric assessment tools.
The trial was designed to compare three non-pharmacological strategies that are practical for use in pediatric oncology nursing care. The purpose was to determine whether sensory stimulation, cognitive-behavioral preparation and coping support, or visual distraction differed in their effects on procedural pain, fear, and anxiety during subcutaneous injection.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cognitive Behavioral Intervention Package GroupBehavioural
The Cognitive Behavioral Intervention Package was delivered by the researcher before, during, and after the subcutaneous injection. Before the procedure, the child received brief age-appropriate preparation, selected a preferred distraction or coping strategy, and the parent was guided on how to support the child. During the injection, the researcher provided standardized verbal coaching, encouragement, and coping support, while the parent provided physical and verbal comfort. The child used the selected coping strategy throughout the injection. After completion of the outcome assessments, brief positive reinforcement was provided. The intervention was implemented using a structured checklist to support standardization.
Buzzy® GroupDevice
The Buzzy® device was used as a cold and vibration intervention during subcutaneous injection. The device was placed at the injection site 60 seconds before needle insertion, and cold and vibration were initiated. Immediately before needle insertion, the device was repositioned approximately 3 cm proximal to the injection site. It remained in place throughout the injection and was removed immediately after the procedure was completed. No additional distraction or cognitive behavioral coaching was provided beyond standard procedural explanations.
Kaleidoscope GroupDevice
The kaleidoscope was used as a visual distraction intervention during subcutaneous injection. The child was shown the kaleidoscope shortly before the procedure and was allowed a brief familiarization period. The kaleidoscope was introduced approximately 1 minute before needle insertion, and the child continued to look through it throughout the injection. The intervention ended when the injection was completed. No additional cognitive behavioral coaching or cold/vibration intervention was provided beyond standard procedural explanations.

What is being measured
The primary outcome is the main question the study is designed to answer.
Post-Procedural Pain Intensity Assessed Using the Wong-Baker FACES Pain Rating Scale
Post-procedural pain intensity will be assessed immediately after subcutaneous injection using the Wong-Baker FACES Pain Rating Scale. This scale ranges from 0 to 5, with 0 indicating no pain and 5 indicating the worst pain. Higher scores indicate greater pain intensity.
Measured: Immediately after subcutaneous injection
Secondary outcomes (2)
Procedural Fear Assessed Using the Children's Fear Scale
Procedural fear will be assessed before and immediately after subcutaneous injection using the Children's Fear Scale. This scale ranges from 0 to 4, with 0 indicating no fear and 4 indicating extreme fear. Higher scores indicate greater procedural fear.
Measured: Before and immediately after subcutaneous injection
State Anxiety Assessed Using the Children's Anxiety Scale-State
State anxiety related to subcutaneous injection will be assessed before and immediately after the procedure using the Children's Anxiety Scale-State. This scale ranges from 0 to 10, with 0 indicating no anxiety and 10 indicating the highest level of anxiety. Higher scores indicate greater state anxiety.
Measured: Before and immediately after subcutaneous injection

Questions about this trial
What is this clinical trial studying?
A study testing Cognitive Behavioral Intervention Package Group, Buzzy® Group and Kaleidoscope Group in people with Pediatric Cancer and Procedural Pain, run by Kocaeli University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-Procedural Pain Intensity Assessed Using the Wong-Baker FACES Pain Rating Scale (time frame: Immediately after subcutaneous injection). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07667712, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2026.
