Development and validation of an elimination ostomy adjustment scale

Abstract

Theoretical framework: An ostomy represents a potential threat to people’s lives and is translated into physical, emotional and social maladjustments. The specific Nursing intervention may positively affect the adjustment to changes, helping people integrate them in their daily lives. Objectives: Development and validation of a psychometric instrument designated as Escala de Adaptação a Ostomia de Eliminação (EAOE) (Elimination Ostomy Adjustment Scale) in ostomy patients. Methodology: The scale was developed based on the Nursing literature, as well as other measuring instruments, with the participation of a panel of experts. The sample was composed of 256 patients with intestinal or urinary elimination ostomies, who were followed up in a stoma therapy Nursing consultation. Construct validity was assessed using the principal components analysis, with varimax rotation. Results: The analysis showed good item quality (KMO=0.812). Six factors were retained, which explained 52.38% of the total scale variance. Reliability was assessed using Cronbach’s alpha (global scale=0.87; subscales= 0.85-0.61). Conclusion: The scale showed good validity and reliability. Further studies should be developed, thus complementing its psychometric analysis.
