Agri Ibrahim Cecen University106 enrolled

Overview

Aim: The aim of this study is to evaluate the effect of mandala coloring on labor pain, childbirth experience, and maternal satisfaction in pregnant women. Materials and Methods: This study was conducted as a randomized controlled trial with a pretest-post test group design including measurements at multiple time points. The study population consisted of pregnant women admitted for vaginal delivery to the labor unit of a hospital between June 1, 2025, and May 1, 2026. Sample size was calculated using the G\*Power 3.1.9.7 program. In the sample size calculation, the Cohen's d = 0.80 value obtained from the reference study was used as the basis and was converted to an approximate effect size of f = 0.40. Analysis performed with a 5% significance level and 80% statistical power indicated that the required minimum sample size for the three groups was 66 participants in total. To prevent potential data loss, support voluntary participation, and increase statistical power, 36 participants were initially planned for each group; however, because one participant in each intervention group was younger than 18 years of age and was therefore excluded, the study was completed with a total of 106 participants in the mandala coloring (n = 35), Nada Yoga music (n = 35), and control (n = 36) groups.

Outcomes

Primary Outcomes

Visual Analog Scale (VAS)

The Visual Analog Scale (VAS) is It is a unidimensional measurement tool used to evaluate labor pain intensity. Pain level is determined by measuring the point marked by the participant on a 10-cm line ranging from 0 (no pain) to 10 (unbearable pain). Higher scores indicate more severe pain perception. The VAS is widely used as a valid and reliable method for the quantitative evaluation of pain perception, particularly in pregnant women and women during labor

Time frame: Baseline, Periprocedural (labor stages: first, second, third)

Personal Information Form

This form was developed by the researchers based on the relevant literature to collect data on the participants' sociodemographic characteristics.

Time frame: Baseline

Birth Satisfaction Scale-Short Form (BSS-S)

The Birth Satisfaction Scale-Short Form (BSS-S) This scale, developed by Martin and Fleming and revised by Martin and Martin, is a 10-item, 5-point Likert-type instrument designed to evaluate women's perceptions of childbirth. The Turkish validity and reliability study was conducted by Göncü and Karahan. Scores obtained from the scale range from 0 to 40, with higher scores indicating greater satisfaction; in the Turkish adaptation, scores were classified as low (\<13), moderate (14-27), and high (≥28) satisfaction. Items are scored between 0 and 4, and items 2, 4, 7, and 8 are reverse coded. Although the original scale included three subdimensions, the Turkish validity study identified two subdimensions with eigenvalues above 1: Personal Attributes \& Stress (PAS) and Quality of Care (QC).

Time frame: Baseline, Periprocedural (labor stages: first, second, third)

State Anxiety Inventory (SAI-I)

The State Anxiety Inventory (SAI-I) It was developed to evaluate anxiety level at a specific moment. The scale was adapted into Turkish by Öner and Le Compte. The scale is a self-report instrument that evaluates the individual's current emotional state. It consists of a total of 20 items, and items are scored on a 4-point Likert scale (not at all = 1, somewhat = 2, very much = 3, completely = 4). Obtained scores range from 20 to 80, with higher scores indicating higher anxiety levels.

Time frame: Baseline, Periprocedural (labor stages: first, second, third)

Labor Process Evaluation Form

The Labor Process Evaluation Form (Appendix 5) is a tool developed by the researcher based on the relevant literature (Tuncay, 2024) to assess the childbirth process of the participants.

Time frame: Periprocedural (labor stages: first, second, third)

Labor Process Evaluation Form (LPEF)

Labor Process Evaluation Form (LPEF): It was prepared by the researcher in accordance with the literature to evaluate clinical and experiential characteristics associated with the labor process in the participants. The form includes labor stages, labor duration, and basic clinical findings related to the mother and newborn

Time frame: Periprocedural (labor stages: third)
