多囊卵巢综合征患者生活方式自评量表的初步编制及信度效度分析

目的 初步探索适用于多囊卵巢综合征(PCOS)患者的生活方式自评量表,并测定其信度效度.方法 对98例PCOS患者采用躯体症状、心理行为、生活习惯和社会功能四要素的行为学问卷量表进行调查.通过因素分析法删减项目、调整结构,进行信度和效度检验,产生19条目的PCOS生活方式自评量表；然后对40例PCOS患者和40例健康对照者进行鉴别效度检验.结果 PCOS生活方式自评量表包含19条目5个因子；因子分析得到特征根大于l的5个因子,累积的解释变异量为56.625％.内部一致性Cronbach'sα系数为0.626 ～0.826,重测信度ICC指标为0.709～0.822.量表中运动意识、体质认识和生活节奏三个因子的得分在PCOS患者和健康对照者间具有显著差异.结论 该量表符合PCOS患者的生活习惯特征,并可为PCOS患者实施生活方式干预提供指导和依据.

Development of lifestyle self-assessment scale in patients with polycystic ovary syndrome and analysis of reliability and validity

Objective To preliminarily develop a lifestyle self-assessment scale being suitable for patients with polycystic ovary syndrome (PCOS) and test its reliability and validity.Methods 98 patients with PCOS were surveyed by behavior questionnaire including somatic symptom,psychological behavior,life habits and social function.The lifestyle self-assessment scale for PCOS including 19 items was generated by factor analysis with cutting items and adjusting structure and tests of the reliability and validity.Then,40 patients with PCOS and 40healthy controls were surveyed to test the scale' discriminant validity.Results The lifestyle self-assessment scale for PCOS was consisted by 19 items which generated 5 factors (each characteristic root ＞ 1,cumulative rate =56.625％ ).The Crunbach' sα was 0.626 ～ 0.826 and the intraclass correlation coefficient was 0.709 ～0.822.There were significant differences in three factors containing exercise consciousness,physique cognition and rhythm of life in the scale between PCOS and control group.Conclusion This scale accords with the living habits characteristics of PCOS patients and can provide guidance and basis for lifestyle intervention.
