Description

This research was designed as a quasi-experimental study with pretest and posttest measurements, based on epidemiological intervention methods. The study will take place in the interventional radiology unit of Muş State Hospital. The study population will include all patients who are admitted to the radiology unit for thyroid (goiter) biopsy. The sample size was calculated using the G*Power 3.1.9.7 program with a medium effect size (0.5), α=0.05, and power (1-β)=0.80, resulting in a total of 68 participants-34 in the intervention group and 34 in the control group.

Inclusion criteria: being literate and not having any psychiatric disorder. Exclusion criteria: having a psychological disorder that may affect the reliability of responses (e.g., bipolar disorder, dementia) or having undergone a thyroid biopsy before.

Participants will be assigned alternately: patients with odd numbers will be in the control group, and even numbers in the experimental group. The experimental group will watch a therapeutic (relaxing) video projected on the wall immediately before and during the biopsy. The video aims to reduce anxiety and discomfort associated with the procedure. Control group patients will receive the routine procedure without any additional intervention.

Data collection tools will include:

Descriptive Information Form: Prepared by researchers to record demographic and clinical characteristics.

Visual Analog Scale for Pain (VAS-Pain): Developed by Freyd (1983) to measure pain intensity on a 10-cm scale (0 = no pain, 10 = worst pain).

State Anxiety Inventory: Developed by Spielberger et al. (1970), validated in Turkish by Öner and Le Compte (1998), used to assess situational anxiety.

Visual Analog Scale for Comfort (VAS-Comfort): A 10-cm visual scale to evaluate patient comfort levels during the procedure (0 = least comfort, 10 = greatest comfort).
