Development and Validation of the Satisfaction Concerning Stoma Care Questionnaire (SSCQ).

Abstract

Purpose: The purpose of this research was to develop the Satisfaction Concerning Stoma Care Questionnaire (SSCQ) and evaluate its structural and convergent validity and internal reliability.

Design: Instrument development and evaluation of validity and reliability.

Subjects and setting: A preliminary 22-item SSCQ was administered in a larger web-based survey to members of 2 ostomy-related patient associations with members throughout the Netherlands. The data of patients who underwent surgery within 2 years were selected for analysis.

Methods: The development of the SSCQ was informed by a preexisting survey that focused on the experiences of stoma patients with general health care. Structural validity and homogeneity of the SSCQ were assessed using explanatory factor analysis and Cronbach's α coefficients. Convergent validity was also evaluated.

Results: The final SSCQ comprised 20 items covering 3 domains: "preoperative care and information," "postoperative care and guidance," and "contact with and ostomy nurse." The SSCQ demonstrated structural and convergent validity and internal reliability. The Cronbach's α value of the SSCQ was 0.95, whereas the independent domains retrieved a high α coefficient ranging from 0.90 to 0.93. The SSCQ and independent domains were able to distinguish between high and low patients' ratings for satisfaction concerning the received stoma care.

Conclusions: The SSCQ demonstrated structural and convergent reliability, along with internal consistency. It may be used to measure the satisfaction of patients with ostomies concerning stoma care. Future prospective studies using the SSCQ are needed to generate additional insights into providing optimal care for ostomy patients.
