Turkish Adaptation of the Stoma-Specific Quality of Life Questionnaire: A Validity and Reliability Study

Aim: This methodological study aimed to evaluate the validity and reliability of the Turkish version of the Stoma-Specific Quality of Life (SQOL-TR) questionnaire, developed to assess the Quality of Life in individuals with enteral and urinary ostomies. Method:The study was conducted with 125 patients with ostomies at the stoma therapy unit of a university hospital in Ankara.Data were collected using a demographic information form, the Quality-of-Life Scale for Individuals with an Ostomy (O-QOL), and the SQOL-TR.In the first stage, linguistic validation and a pilot test were conducted.In the second stage, construct validity was assessed using confirmatory factor analysis, and concurrent validity was evaluated through comparison with the O-QOL.Reliability was tested via Cronbach's alpha, composite reliability, and item analysis.Results: Participants had a mean age of 59.6612.70 years and an average ostomy duration of 16.4721.86months.Of these, 40.0% had colostomies, 29.6% ileostomies, and 26.4% urostomies.Psychometric analyses revealed a content validity index of 1.00.The questionnaire consisted of four subdimensions: elimination concerns, psychological impact, daily activities, and social relationships.It showed a strong positive correlation with the O-QOL (r=0.78,p<0.001) and a reliability coefficient of 0.964.All items demonstrated high discriminative power. Conclusion:The SQOL-TR is a valid and reliable instrument for individuals with colostomies, ileostomies, or urostomies.Adapted into six cultures, it is suitable for use in multicenter and multinational research as well as clinical follow-up.
