安全感量表在莆田市老年人群中信度和效度的检验

Test on Reliability and Validity of Security Questionnaire in Putian Elderly Population

目的考评安全感量表(SQ)应用于莆田市老年人安全感状况的信度和效度。方法应用安全感量表(SQ)和自我接纳问卷(SAQ)对586例莆田市老年人进行测试。结果安全感量表评价老年人安全感的2周重测信度为0.756(P<0.001),分半信度为0.771,Cronbach'sα系数为0.805;量表2个维度的集合效度和区分效度试验成功率均为100%;因子分析提取4个公因子,累积解释变异量54.384%,与理论构想基本相符;量表总分与自我接纳问卷总分相关系数r=0.712(P<0.001)。结论安全感量表具有较好的信度和效度,适合用于莆田市老年人安全感的测量。

Objective To examine the reliability and validity of Security Questionnaire（ SQ） in evaluating sense of security of Putian elderly population. Methods A total of 586 Putian elderly people were investigated with Security Questionnaire（ SQ） and Self Acceptance Questionnaire（ SAQ）. Results The retest reliability of SQ for evaluating the elderly population＇s security condition during 2 weeks was 0. 756（ P〈0. 001）. The split- half reliability was 0. 771 and Cronbach＇s α- coefficient was 0. 805. The success rates of tests on collection validity and differentiate validity of the two dimensions were both 100%. Through factor analysis,we got four common factors,and cumulative explained variance was 54. 384,which was consistent with theoretical construct of the scale. The correlation coefficient of the total scores of SQ and SAQ was 0. 712（ P〈0. 001）. Conclusion SQ has relatively high reliability and validity,thus is suitable for evaluating the security condition of Putian elderly population.
