目的:对孕期心理相关危险因素筛查表进行信度和效度检验,评价筛查表的适用程度。方法:在5家妇幼保健机构中共调查孕妇630名,通过相关分析、探索性因子分析、信度分析和效度分析等方法完成筛查表的效能考评。结果:通过条目再筛选剔除了3个反应性较低的条目;信度考评结果均在0.6左右,已达到一定的要求;筛查表与校标量表SAS、SDS的相关系数分别为0.518和0.500,呈中度相关。结论:孕期心理相关危险因素筛查表的信效度考评结果基本达到要求,建议通过干预试点进一步改善其效能。
OBJECTIVE: To test the reliability and validity of the screen of psychological risk factors in pregnancy and evaluate the applicability of the screening table. Methods: In the five maternal and child health institutions, a total of 630 pregnant women were surveyed by means of correlation analysis, exploratory factor analysis, reliability analysis and validity analysis to complete the screening test. Results: Three entries with low reactivity were eliminated by item re-screening. The reliability test results were all around 0.6, which met certain requirements. The correlation coefficients between screening table and school-scale SAS and SDS were 0.518 and 0.500 , Was moderately related. Conclusion: The reliability and validity of the screening test of psychologically related risk factors during pregnancy basically meets the requirements. It is suggested that the effectiveness of interventions should be further improved through intervention trials.
