About this study

Official title: Effect of a Nature-View Curtain Used as a Distraction Method on Pain, Anxiety, and Fear During Ultrasound-Guided Thyroid Fine-Needle Aspiration Biopsy: A Randomized Controlled Trial

Thyroid fine-needle aspiration biopsy (FNAB) may cause procedure-related pain, anxiety, and fear. This randomized controlled trial evaluated whether visual distraction with a nature-view curtain could reduce these outcomes. A total of 100 adults undergoing ultrasound-guided thyroid FNAB were randomly assigned in a 1:1 ratio to a nature-view curtain group or a standard-care control group. Participants in the intervention group were instructed to focus on a ceiling-mounted nature-view curtain throughout the biopsy, whereas participants in the control group underwent routine biopsy without this visual distraction. Pain intensity was the primary outcome; anxiety and fear of pain were secondary outcomes. Outcomes were assessed approximately 15 minutes before and approximately 15 minutes after the procedure.

Read the detailed description

This completed, two-arm, parallel-group, randomized controlled trial was conducted at Adana City Training and Research Hospital in Adana, Türkiye, between June 1, 2025, and February 28, 2026.

The study included 100 adults scheduled to undergo ultrasound-guided thyroid fine-needle aspiration biopsy because of a suspected thyroid nodule or mass. Participants were stratified by sex and assigned in a 1:1 ratio to the nature-view curtain group or the standard-care control group using blocks of two. Within each sex stratum, the first participant in each block was assigned by coin toss, and the second was allocated to the other group.

Both groups underwent routine ultrasound-guided thyroid fine-needle aspiration biopsy. Participants in the intervention group were instructed to focus throughout the procedure on a ceiling-mounted, 195 × 135 cm curtain displaying a nature scene. Participants in the control group underwent the routine biopsy procedure without nature-view curtain distraction. The biopsy procedure lasted approximately 5 to 10 minutes.

Pain intensity, anxiety, and fear of pain were assessed approximately 15 minutes before and approximately 15 minutes after the procedure. Pain intensity assessed using the Visual Analog Scale was the primary outcome. Anxiety assessed using the Beck Anxiety Inventory and fear of pain assessed using the Fear of Pain Questionnaire-III were secondary outcomes.

Because of the nature of the intervention, participants and study personnel were not masked. Statistical analyses were conducted by an independent statistician who received coded group data and was unaware of the group identities.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analogue Scale

    The Visual Analogue Scale (VAS) is a 10-cm (100-mm) scale used to assess pain intensity. Scores range from 0 ("no pain") to 10 ("worst imaginable pain"), with higher scores indicating greater pain intensity. Assessments were performed approximately 15 minutes before the ultrasound-guided fine-needle aspiration biopsy procedure and approximately 15 minutes after completion of the procedure.

    Measured: Approximately 15 minutes before and approximately 15 minutes after the ultrasound-guided fine-needle aspiration biopsy procedure.

Secondary outcomes (2)
  1. Fear of Pain Questionnaire-III (FPQ-III)

    The Fear of Pain Questionnaire-III (FPQ-III) is a 30-item instrument assessing fear of pain across three domains: severe pain, minor pain, and medical pain. Items are scored on a 5-point Likert scale, yielding a total score ranging from 30 to 150, with higher scores indicating greater fear of pain. Assessments were performed approximately 15 minutes before the ultrasound-guided fine-needle aspiration biopsy procedure and approximately 15 minutes after completion of the procedure.

    Measured: Approximately 15 minutes before and approximately 15 minutes after the ultrasound-guided fine-needle aspiration biopsy procedure.

  2. The Beck Anxiety Inventory (BAI)

    The Beck Anxiety Inventory (BAI) is a 21-item self-report questionnaire used to assess the severity of anxiety symptoms. Total scores range from 0 to 63, with higher scores indicating greater anxiety severity. Assessments were performed approximately 15 minutes before the ultrasound-guided fine-needle aspiration biopsy procedure and approximately 15 minutes after completion of the procedure.

    Measured: Approximately 15 minutes before and approximately 15 minutes after the ultrasound-guided fine-needle aspiration biopsy procedure.

Model description
This was a two-arm, parallel-group, randomized controlled trial with pre-intervention and post-intervention assessments. Participants were stratified by sex and assigned in a 1:1 ratio to the nature-view curtain group or the control group using blocks of two. Within each sex stratum, the first participant in each block was assigned by coin toss, and the second was allocated to the other group. Both groups underwent routine ultrasound-guided thyroid fine-needle aspiration biopsy; only the intervention group was instructed to focus on the nature-view curtain during the procedure.

Questions about this trial

What is this clinical trial studying?

A study testing Nature-View Curtain Visual Distraction in people with Thyroid Nodule (Diagnosis), run by Dicle 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 2 inclusion and 1 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 27 Aug 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?

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?

Visual Analogue Scale (time frame: Approximately 15 minutes before and approximately 15 minutes after the ultrasound-guided fine-needle aspiration biopsy procedure.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 27 Aug 2026.
