Summary
The Turkish version of the stoma self-efficacy scale is a valid and reliable tool for assessing self-efficacy in individuals with stomas, crucial for improving their quality of life.
Area of Science:
- Nursing
- Psychometrics
- Quality of Life Research
Background:
- Self-efficacy in stoma care is vital for adherence and enhancing the quality of life for individuals with stomas.
- Assessing and improving self-efficacy are key to patient well-being and successful stoma management.
Purpose of the Study:
- To evaluate the validity and reliability of the stoma self-efficacy scale for Turkish-speaking populations.
- To provide a culturally adapted and psychometrically sound instrument for measuring stoma self-efficacy.
Main Methods:
- A methodological study involving translation, back-translation, and expert review for language and content validity.
- Face validity was assessed by an expert panel and individuals with stomas.
- Reliability (internal consistency, test-retest) and construct validity (exploratory and confirmatory factor analysis) were examined in 174 participants.
Main Results:
- The scale demonstrated excellent content validity (CVI = .96) and internal consistency (Cronbach's alpha = .95).
- Test-retest reliability was high, indicated by strong intraclass correlation coefficients.
- Factor analysis confirmed a two-factor structure, and confirmatory factor analysis supported the model's good fit, indicating strong construct validity.
Conclusions:
- The Turkish version of the stoma self-efficacy scale is a valid and reliable instrument.
- This validated scale can effectively measure self-efficacy levels in Turkish-speaking individuals with stomas.
- The findings support the use of this scale to guide interventions aimed at improving stoma care and patient outcomes.

This process nurtures a critical component of self-esteem:...

Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
