Abstract

PURPOSE
This study was to develop a valid and reliable self-care performance scale for stomach cancer patients with gastrectomies.
METHODS
The initial items for the self-care performance scale were derived by a literature review and in-depth interviews with stomach cancer patients with gastrectomies and a conceptual framework based on Orem's theory was used. The identified items were evaluated for content validity by experts. The main survey with refined items was performed with a sample of 232 patients. The data were analyzed using item analysis, Pearson correlation coefficients, Cronbach's alpha and factor analysis.
RESULTS
A 22 item instrument with 7 factors was developed and the total variance explained was 66.9%. The factors were 'manage dietary restriction', 'avoid hazards', 'rest and elimination', 'manage social support and stress', 'regulation diet', 'meal portion control' and 'seek information and follow-up care'. The internal consistency, Cronbach's alpha was .86 and reliability of the subscale ranged from .65 to .82.
CONCLUSION
This study suggested that the self-care performance scale is a reliable and valid instrument to measure self-care performance for patients with stomach cancer after gastrectomy.
