# Cultural adaptation and validity evidence of the Student Nurse Stressor-15 (SNS-15) Scale for Brazil

## TL;DR

This study adapted and validated the Student Nurse Stressor-15 Scale for use in Brazil, confirming its reliability and validity.

## Contribution

The paper provides a culturally adapted and validated version of the SNS-15 for Brazilian nursing students.

## Key findings

- The SNS-15 items were distributed into four factors through exploratory factor analysis.
- Confirmatory factor analysis showed satisfactory fit indices for the Brazilian version of the scale.
- The instrument demonstrated high reliability with McDonald’s Omega of 0.86.

## Abstract

to carry out the cultural adaptation and evaluation of validity evidence of the Student Nurse Stressor-15 (SNS-15) Scale for use in Brazil.

psychometric study, conducted from the stages of translation, synthesis, back-translation, review by a committee of seven experts, pre-test and evaluation of measurement properties with 32 and 238 nursing students, respectively. Descriptive statistics, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA) were performed. The reliability of the instrument was estimated using McDonald’s Omega (ω).

EFA subsidized the distribution of the fifteen SNS-15 items into four factors. Using AFC, satisfactory fit indices were achieved (Comparative Fit Index = 0.94; Tucker-Lewis Index = 0.93; Root Mean Square Error of Approximation = 0.06; Standardized Root Mean Square Residual = 0.16) and ω = 0.86.

the Brazilian version of the SNS-15 presents evidence that confirms its validity and reliability.
