慢性HBV感染孕妇疾病相关心理压力量表的初步编制及信效度评价

目的初步编制慢性HBV感染孕妇疾病相关心理压力量表并对其信效度进行检验，为评价慢性HBV感染孕妇与疾病相关的妊娠期心理压力提供测评工具。方法在全面检索文献的基础上通过访谈法发展条目池，经专家审议评定重修后形成量表。对368例慢性HBV感染初产孕妇进行测试，对量表信效度进行评价。结果量表共包含5个因子，24个条目；本量表各因子得分与总分之间相关系数为0．712—0．894，呈高度相关；各因子之间相关系数在0．409～0．631之间，均低于各因子与总分的相关系数，差异均有统计学意义（P〈0．01）；5个公因子累积贡献率达64．055％；5个因子重测信度分别为0．856，0．887，0．828，0．813，0．801，总量表重测信度为0．895；量表5个因子内部一致性信度Cronbaeh’S仅系数为0．788—0．865，量表总体Cronbaeh’S仅系数为0．932。结论该量表具有较好的信度和效度，可用于测量慢性HBV感染孕妇与疾病相关的妊娠期心理压力。

Preliminary establishment, reliability and validity test of the disease related psychological pressure scale of pregnant women with chronic HBV infection

Objective To establish and test the reliability and validity of the disease related psychological pressure scale of pregnant women with chronic HBV infection, so as to provide mental stress assessment tool for the pregnant women. Methods Item pool was developed after the interview and comprehensively retrieved literatures ,then after expert review and rebuilt, the scale items were fixed. Totals of 368 pregnant women with chronic HBV infection disease were investigated and the reliability and validity of scale were test. Results The scale had 5 factors and 24 items, and the correlation coefficient between each factor score and total score was 0. 712 - 0.894. The correlation coefficient among each factor was 0.409 - 0.631 which was significantly lower than that between each factor score and total score （ P 〈 0. 01 ）. The cumulative contribution rate of 5 factors was 64. 055%, and tes-retest reliability of 5 factors was O. 856,0. 887,0. 828, 0.813. The Cronbach＇ s a of internal consistency of 5 factors was 0. 788 -0.865 ,and the Cronbach＇ sot of scale was 0.932. Conclusions The scale has good reliability and validity, and can be used for measuring the disease related pregnancy psychological pressure for chronic HBV infection pregnant women.
