Development and reliability and validity test of Ulcerative colitis patient self-management Scale / 中国实用护理杂志

ABSTRACT

Objective:To develop a self-management scale for patients with ulcerative colitis and test its reliability and validity,so as to provide a measurement tool for evaluating the self-management level of patients with ulcerative colitis in China.Methods:Guided by the theory of self-management, combined with extensive literature review and semi-structured interview results, the initial item pool was formed, and the initial questionnaire was formed through expert consultation. 324 cases of ulcerative colitis in a third-class Hospital of Tianjin were investigated by convenience sampling.Results:The self-management scale of ulcerative colitis patients included 4 dimensions and 23 items. The content validity of each item was between 0.867 and 1,and the content validity index of the scale was 0.860. Four factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate of variance was 66.395%. The Cronbachs coefficient of overall scale was 0.937,while four dimensions was between 0.820 and 0.916. The retest reliability of the scale was 0.934 ( P<0.01) and the retest reliability of each dimension was between 0.914 and 0.950 ( P<0.01). Conclusions:The self-management scale of patients with ulcerative colitis has been developed. The scale includes four dimensions disease treatment management,daily life management,psychosocial management and disease information management. It has 23 items in total and has good reliability and validity. It can be used to evaluate the self-management level of patients with ulcerative colitis.
