溃疡性结肠炎患者自我管理量表的编制及信效度检验

Development and reliability and validity test of Ulcerative colitis patient self-management Scale

目的编制溃疡性结肠炎患者自我管理量表并进行信效度检验,为评估我国溃疡性结肠炎患者的自我管理水平提供测量工具。方法本量表的编制以自我管理理论为指导,结合广泛查阅文献及半结构访谈结果,初步形成条目池,通过专家咨询,形成初始问卷。以便利抽样的方法采用初始量表调研了324例南开大学附属天津市人民医院溃疡性结肠炎患者。结果溃疡性结肠炎患者自我管理量表包括4个维度,23个条目。各条目内容效度为0.867~1.000,量表内容效度为0.860。探索性因子分析共提取4个公因子,累积方差贡献率为66.395%。总量表Cronbachα系数为0.937,各维度Cronbachα系数为0.820~0.916。量表重测信度为0.934(P<0.01),各维度重测信度为0.914~0.950(P<0.01)。结论本研究初步编制了溃疡性结肠炎患者自我管理量表。量表包括疾病治疗管理、日常生活管理、心理社会管理、疾病信息管理4个维度,共23个条目,且具有良好的信效度,可用于测评溃疡性结肠炎患者的自我管理水平。

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.
