恶性肿瘤患者同伴支持需求量表的编制和信效度检验

Development and reliability and validity test of peer support demand scale for patients with malignant tumor

目的 编制恶性肿瘤患者同伴支持需求量表,并进行信效度检验,为评估恶性肿瘤患者对同伴支持的需求提供测评工具.方法 以同伴支持理论为指导,通过理论回顾和质性访谈,拟定同伴支持需求调查量表条目池,通过两轮专家咨询和量表预调查,确定量表条目初稿.采用量表初稿对300例肿瘤患者进行问卷调查,测评量表的信效度.结果 恶性肿瘤患者同伴支持需求量表包括同伴支持了解需求、情感需求、信息需求、评价需求4个因子,共21个条目,累计方差贡献率为59.684%.量表内容效度（S-CVI）为0.920,内部一致性信度Cronbacha′sα系数为0.815,重测信度为0.824.结论 该量表的内容效度、内部一致性信度均在可接受的范围内,基本达到了编制目的,可用于恶性肿瘤患者同伴支持需求的调查.

Objective To develop a peer support demand scale for patients with malignant tumor, and to test its reliability and validity,so as to provide an assessment tool for evaluating demand of peer support in patients with malignant tumor.Methods Guided by peer support theory,with theoretical review and qualitative interview,item pool of the peer support demand scale was preliminarily made. After a two-round expert consultation and preliminary scale investigation,first draft of the items was determined. 300 patients with malignant tumor were surveyed by the first draft of the scale,so that reliability and validity of the scale were tested.Results In the peer support demand scale for patients with malignant tumor,4 factors with 21 items were included,namely demands on peer support understanding,emotion,information and evaluation,The cumulative variance contribution rate was 59.684%. The content validity （S-CVI） was 0.920. Cronbacha′s α coefficient of the internal consistency reliability was 0.815,and the retest reliability was 0.824. Conclusions Content validity and internal consistency reliability are within acceptable range,which makes it basically qualified and can be used for investigation on patients with malignant tumor about their peer support demands.
